The great battle of enterprise storage is on!

The time has come to take sides on the core question of storage for virtual servers: Do you want storage intelligence to live in the hypervisor or the array? Most administrators are already lining up on one side or the other, unintentionally casting their vote while the rest flounder. But the storage industry must wake up and embrace the divide.

Hypervisor Huggers Unite!

Do you "heart" virtualization?

VMware’s vSphere dominates the world of enterprise server virtualization and has become the core element of the modern open systems datacenter. Microsoft recognizes this but has been unable to field a competitive hypervisor ecosystem for the virtual datacenter. Today, vSphere is the state of the art and nowhere is this more apparent than in storage.

In just a few years, VMware has delivered and updated a host of advanced storage functionality, from provisioning to migration and load balancing to backup and data protection. vSphere 5 includes an advanced and scalable storage virtualization layer, delivering everything a datacenter needs. VMFS sculpts basic block storage into a shared resource for virtual machines, with snapshots, policy-based layout and movement, and flexible allocation and thin provisioning.

Most VMware administrators are “server guys” and relish these features. They have never experienced an automated “storage service” like this, and the enterprise storage world has never been able to construct anything remotely as flexible, user-friendly, and functional. And Hypervisor Huggers don’t need complex enterprise storage arrays to do it: They can use basic iSCSI or Fibre Channel devices to provide performance and capacity and let VMware do the rest!

Storage DRS is exemplary of the new virtual datacenter world. Introduced in vSphere 5 (and restricted to the pricey Enterprise Plus license), Storage DRS uses the core technology of Storage vMotion to dynamically balance I/O and capacity across a diverse pool of storage. Storage DRS even uses Policy-Driven Storage and VASA to enforce tiered storage and data placement strategy. This kind of virtualization has been a “holy grail” quest for the enterprise storage industry, but they’ve never delivered on their promises.

Cheers for Storage Stalwarts!

Do you wish all this virtualization nonsense would just go away?

But not every IT environment wants be 100% vSphere focused, and many aren’t convinced that dumb storage is the smartest place for their data. These Storage Stalwarts want smarter and better-integrated storage arrays, and VMware is innovating here as well.

VMware’s Storage APIs for Array Integration (VAAI) technology is squarely aimed at this market. VAAI allows vSphere to hand off heavy storage operations to the high-end storage arrays from the major players. It works transparently, too, coordinating cloning without the kind of scripting and hair-pulling that used to require. VAAI in vSphere 4.1 also includes block zeroing support and something called “atomic test and set” which we’ll get to in a moment. Microsoft announced their own cloning integration, ODX, but it won’t ship until Windows Server 8 appears sometime next year.

But cloning is just the tip of the iceberg when it comes to Hypervisor-to-array integration. The rising army of NAS users have seen the glory of more-complete array integration for a while, and they’re not quiet about it. They love that VMware’s NFS protocol support makes storage “disappear” in vCenter, becoming just another resource with integrated thin provisioning and flexible allocation and movement.

VMware is moving aggressively to please their Storage Stalwarts, adding more VAAI support for block and file in vSphere 5. But, as the company laid out at VMworld 2011, neither access method is ideal for virtual servers. So VMware has been pushing the enterprise array vendors for ever-greater integration. They see a future where a VAAI-based protocol enables arrays to de-multiplex I/O streams from the hypervisor and intelligently handle per-VM data.

Stephen’s Stance

You can spot a Hypervisor Hugger by their big LUNs: They would rather treat storage as a bulk commodity, and array vendors should be lining up to get their business. Storage Stalwarts will jump on each new VMware innovation, finally making use of the capabilities they have spent over a decade paying for but not utilizing. The only untenable stance is trying to keep a foot in both worlds: It’s foolish to buy an enterprise array and use it as bulk storage!

• Storage Fixes in VMware ESX Server 3.5 Update 2
• Storage Changes in VMware ESX 3.5 Update 3
• Storage Changes in VMware ESX 3.5 Update 4
  
• Storage Changes in the VMware vSphere 4 Family

One first step is VMware’s whitepaper, “What’s New in VMware vSphere 5.0 – Storage“.

Licensing and Availability of Features

VMware has once again changed the licensing and pricing model, throwing the Internet into a tizzy:

• “Advanced” has been eliminated, moving up to “Enterprise”
• Pooled vRAM entitlements work across the entire vCenter environment
• New features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses
• VAAI, PSP multipathing, and Storage vMotion are only found in “Enterprise”
• Thin Provisioning and VADP are available regardless of edition

VMware mucked with vSphere licensing again...

Major New vSphere 5 Storage Features

Storage DRS

Storage DRS is the world’s worst-kept secret, with everyone and his brother talking about it for over a year. Like the existing VM DRS capability, Storage DRS creates resource clusters and automatically moves VMs between them. Storage DRS uses utilization and performance metrics to make the call, and has three modes of operation. It sounds awesome, but it’s an Enterprise Plus-only feature.

Storage APIs – Storage Awareness (VASA)

There’s not much information presently, but a VAAI companion is introduced in vSphere 5: The vSphere Storage APIs for Storage Awareness (VASA) is a communication mechanism for vCenter to detect array capabilities like RAID Level, Thin Provisioning State, Replication State, etc. This will come in handy for all the other features in vSphere 5, especially policy-driven storage!

Policy-Driven Storage

Another new Enterprise Plus feature is Policy-Driven Storage. This allows storage tiers to be defined in vCenter based on SLA, performance, and other metrics which are used during provisioning, cloning, Storage vMotion, and Storage DRS. It leverages VASA for metrics and characterization and supports all arrays in the HCL, regardless of whether they’re NFS, iSCSI, or FC. It includes easy compliance status reporting in vCenter as well.

FCoE Software Initiator

Those of us “in the know” about storage expected VMware to add software FCoE support, so it’s no surprise that they did. This dramatically expands the potential FCoE footprint from just the few CNAs already supported in vSphere 4. It appears to be based on Intel’s OpenFCoE, since it shows up as “Intel Corporation FCoE Adapter” in the GUI!

vSphere Storage Appliance (VSA)

VMware enters the virtual storage appliance (VSA) market with their own offering, the vSphere Storage Appliance (also called VSA). Aimed primarily at the SMB market, it’s actually fairly clever, replicating storage between two or three nodes in a cluster for high availability and using NFS for access rather than iSCSI. And unlike the Celerra UBER that so many techies loved, the VMware VSA is ready for production use!

Existing Storage Features Enhanced in vSphere 5

VMFS 5

VMFS has been improved for scalability and efficiency, but the 2 TB limit on VMDKs remains (except for physical RDM). Only storage geeks like me need to worry about the specifics, but suffice to say that VMFS 5 requires less tuning and worrying and ought to scale and perform better thanks to increased maximums and leveraging the Atomic Test and Set (ATS) technology also used in VAAI. For newly-created volumes, there’s no more block size tuning, and alignment issues are addressed.

Storage APIs – Array Integration (VAAI 2)

See also VMware VAAI Storage Array Support in Plain English

VAAI has been revved, bringing back Thin Provisioning Stun (the AWOL “fourth primitive”) and adding NFS support.

There are now five block primitives for VAAI, depending on if you count thin space reclaim. This is really more of a bug fix than anything, since most folks assumed that the existing thin support already reclaimed deleted VMs and vMotioned VMDKs. I’m more interested in the addition of SCSI UNMAP in addition to WRITE_SAME! There’s also some additional T10 support, though I’m not clear on what it is or where it works.

We’ve also got VAAI for NFS environments now. NAS had sweet thin provisioning support even before block datastores, but the new Reserve Space command adds thick provisioning if that’s what you like. We’ve also got Full File Clone, which is like Full Copy for NFS but doesn’t work with Storage vMotion. And there’s some Extended Stats API to bring in more detail on file status. I also hear there’s an API for Native Snapshot Support, but it’s not widely discussed. Finally, note that NFS plugins come from vendors, not VMware as is the case for block VAAI.

Storage I/O Control

SIOC is enhanced for use in Storage DRS environments, becoming aware of the new datastore clusters. It also gets NFS support, and presumably uses VASA for metrics. But it’s still only available with Enterprise Plus licenses.

iSCSI Initiator GUI

The solid vSphere iSCSI initiator gets a friendly GUI for configuration. I like friendly iSCSI GUIs – just ask Microsoft!

Storage vMotion

The mechanism behind Storage vMotion has changed for a third time in as many releases, this time using “Mirror Mode” to mirror writes to in-progress vMotions. It also now supports migration of vSphere snapshots and Linked Clones. This can be offloaded for VAAI block, but not NFS.

vSphere Replication

New in vCenter Site Recovery Manager 5.0 is software-based replication. Although not technically a vSphere 5 feature, this is a major new storage feature in the VMware world. It allows any-to-any software-based storage replication for disaster recovery.

Stephen’s Stance

Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses. I can’t blame VMware for making a buck, but it would be nice if more capabilities were available to the small shops!

I’ll be writing on all these features in detail shortly. Watch this space!

How granular is your storage? This question is just as relevant today as when I first published this article in 2008!

Many storage challenges focus on correlating high-level uses of data (such as applications) with the nuts and bolts of storage infrastructure. These discussions often revolve around the conflict between data management, which demands an ever-smaller unit of management, and storage management, which benefits most from consolidation. Developing data management capability that is both granular enough for applications and scalable enough for storage is one key to the future of storage.

Storage Management: Scaling Up

As I discussed in a previous Sunday Series piece, Turning the Page on RAID, the data storage industry has traditionally focused on reducing granularity. Disk capacity has expanded, and RAID technology has multiplied this by combining multiple physical drive mechanisms into a single virtual one. Storage virtualization technologies, from the SAN to the server, have also often been touted primarily as a mechanism to reduce heterogeneity. From a technical perspective, therefore, granularity has been an obstacle to overcome.

The core organizational best practice for storage management is the reduction of complexity and the enforcement of standardization. Consolidation of storage arrays and file servers is a common goal, as IT seeks to benefit from economies of scale. The goal of both initiatives is the creation of a storage utility or managed storage service. This mirrors efforts on the server and network sides to consolidate and virtualize hardware.

Although both technological and organizational factors have traditionally driven granularity out of storage, this does not have to be the case. Virtual pools of storage are ideal for providing storage on demand, as disk-focused RAID groups give way to more flexible sub-disk storage arrangements. And an operational focus on standardized storage service offerings has the potential to enable scalable management of these smaller units.

Filing Service

File-based protocols would seem to have more potential for granular storage management, but they have been undermined by the hierarchical nature of modern file storage. Whether the connection to a file server uses NFS, CIFS, or AFP, the key unit of management is actually the shared directory, not the file. All files in the share \\firefly\backups would be located on the same server and would be managed as a unit.

NAS virtualization can change this somewhat, as can more specialized NAS servers. Although Microsoft DFS enables consolidation and virtualization of NAS shares, it does not allow subdivision of shares below the directory level – all files in a directory must be placed on the same server. Tricks like stubbing and links allow for some movement, but these do not solve the core issue. Specialized virtual NAS devices from F5 (the ARX, nee Acopia), NetApp, BlueArc, Symantec, and others have the ability to move files individually, providing as much a virtualized storage environment as any block-focused enterprise array. Avere is also beginning to talk about granular file management.

But even an ideal virtualized file server lacks the kind of granularity demanded by users. They care about data, not files, and most applications consolidate their data storage into a few files. Consider a database, for example, where users want each record treated uniquely but storage devices see just a few much larger files. We need a storage revolution, where someone creates an ideal storage platform in which each individual record or object includes custom metadata and is managed independently. This would truly be a massive change, however, and it is not clear that all applications will follow the object storage model of Google and Amazon.

Small is Beautiful

Barring a revolution in data management, our best hope is to allow greater granularity in storage management. As mentioned above, virtualization technology has the potential to enable management and protection of any unit of storage, right down to the individual block or record. But the reality of storage virtualization has not matched its promise.

What is needed is greater integration. Each layer of virtualization (file system, volume manager, hypervisor, network, array, and RAID) also hides necessary details from lower layers. Consider the case of a virtual server snapshot: The application and filesystem must be in a quiesced state to allow a snapshot to be taken at the storage level, but the storage array has no intrinsic information about how its capacity is used. A given LUN might contain dozens of servers on a shared VMFS volume, so all must be snapped together.

Integration can be enabled by sharing more information through APIs. VMware leverages Microsoft Volume Shadow Copy Service (VSS) integration for shared storage so a VMFS snapshot can call the operating system and even applications (Windows Server 2003 only, for now) to prepare the data. Similarly, VSS can communicate directly with supported iSCSI and Fibre Channel arrays, calling a snapshot at the right moment. And Microsoft is, no doubt, enhancing VSS as we speak.

As virtualization technology matures, expect this type of integration to improve. We hope to see more APIs exposed by VMware and Microsoft, allowing communication up and down the stack to break through the information barrier. Imagine a future where a standard API like VSS can pass a message through VMware, Xen, and Hyper-V to the underlying storage array to initiate a snap. I predict that this kind of integration-enabled granularity is not too far off.

Do we really need parallel NFS?

Did some pNFS proponent slip a love potion into the coffee at EMC? Suddenly it’s pNFS time at the company known for its reluctance to embrace file sharing and filesystems in general. The purple prose is flying, with Chad Sakac declaring himself “a big fan of the application of NFS” and Chuck Hollis extolling the “inherent simplicity and ease-of-management of NFS.” The NetApp guys must be amused by the bear hug from Hopkinton, but many are seeing deja-vu all over again.

Chad’s Icky Bits

(Apologies for that heading, but those are Chad’s words, not mine)

Chad Sakac’s red rose for pNFS included a few thorns aimed at good old NFSv3. He calls these the “icky bits” and spills some ink over them:

1. “NFS Server failure behavior,” says Chad, leads to issues as serious as “a guest OS crash” and administrators “resorting to unnatural acts” to compensate. He talks about EMC’s DART OS being optimized to fail over in under a minute to avoid application issues and the difficulty in actually accomplishing this feat.
2. Chad also points out that “NFS client limitations” can lead to “unexpected bottlenecks.” Load balancing large workloads across multiple gigabit Ethernet NICs means hand-tuning, since NFS pins traffic to a single MAC address.

Certainly these limitations were known to many in the storage industry, but haven’t they also been addressed repeatedly? NetApp, EMC, and BlueArc do indeed suggest adjusting NFS heartbeat values to allow time for the cluster to recover, but this seems more a limitation of their clustered server architecture than of NFS itself. Scale-out NFS servers from Isilon and HP don’t seem to require these “unnatural acts.”

As for client limitations, manually balancing client loads is a reality in many large storage architectures, not just NFS. Perhaps the fact that NFS can handle so many more I/O requests in a given timeslice makes this more of an issue, but it tends to be transient.

Chad has repeatedly expressed his love for NFS, especially as a datastore for VMware. Clearly, he intended to point out these “icky bits” to highlight the possibilities for pNFS. But the method used (calling them “icky” for one) resembles mud slinging.

Chuck Wants pNFS

(Chuck’s titles also lend themselves to mis-reading)

Chuck Hollis is more careful in his wording, extolling the virtues of pNFS without calling anything “icky”. Indeed, there’s just one NetApp dig: He says their “emulated containers of LUNs” are “hardly optimized”, which is a welcome change of tone from previous debates.

But the underlying message is the same: pNFS is new and wonderful, encouraging proliferation of hand-holding, flower distribution, and rainbows. Again I ask, is this really true? Is pNFS ready for this kind of adulation when, as Chuck points out, “it’s going to take a while before the rest of the portfolio, industry and ecosystem catches up.  Maybe a year or so.”

Seriously? A year until pNFS is ready for mass enterprise adoption? Admittedly, EMC has been working on pNFS (as MPFS) for a long time, but predictions of “just another year” for a major protocol transition set off warning bells. This is doubly true when most clients (including VMware) don’t yet offer even basic support.

Stephen’s Stance

One wonders if airing this dirty laundry is an attempt to highlight EMC’s pNFS work or to discredit plain old NFS as a datacenter protocol. As I wrote about in Our New Thing Is Awesome (‘Cause Our Old Thing Sucked), the “parade of progress” sometimes degenerates into “out with the old,” and this is perilous for purveyors of durable goods like storage systems.

I am also very concerned with the proliferation of “layout types” within pNFS. It seems that every vendor has a hand in the protocol, and each is adding their own technology to the mix. We started with files and now have both objects and blocks. Will these be widely supported? Do we really need them? Or will pNFS start looking like Bluetooth: Bloated, incompletely-implemented, and ignored except for special use cases.

But my motivation behind this post is simpler than that. I would like to pose a question: Is NFS (v3) really that “icky”? Do we really need pNFS? Or have these problems been solved previously?

Iomega's new ix12-300d brings EMC's SOHO company into the data center

EMC’s Iomega unit today released the 12-drive rack-mount storage product we have all been waiting for. It was never a question of whether Iomega could produce such a beast: The EMC LifeLine software and Iomega hardware were definitely up for it. The question was always if EMC would direct Iomega to fill the gaping hole in their storage lineup between the 4-drive ix4-200r and the entry-business AX4 arrays. The new ix12-300r packs 12 drive bays, scaling from 4 TB all the way to 24 TB, and backs it with quad gigabit iSCSI, redundant power, and everything else the small data center needs.

Stepping Up

The ix12 is a big step up. Although they sold multi-drive RAID systems even before the EMC acquisition, this new device is unlike anything we’ve seen before from Iomega. This slim (2U) chassis is all drives up front, with 12 hot-swap slots full of 3.5″ SATA storage. Under the hood is a dual-core 3 GHz Intel Core2duo E8400 “Wolfdale” CPU, a major horsepower upgrade from the single-core Celeron in the ix4-200r. It also has double the memory (2 GB) compared to that 4-drive product.

It all makes sense now: EMC's storage spectrum, from home to enterprise

If you’re concerned about performance after trying out a desktop ix4-200d, you needn’t worry. The desktop unit has a lowly 1.2 GHz Marvell 6281 and just 512 MB of RAM. While this might be enough for a desktop user, it could never handle the pounding of servers in a shared networked configuration. The ix4-200r, with its 3.2 GHz Intel Celeron D 352 “Cedar Mill“, offered much better performance even though its name was just one letter different. And the ix12′s CPU is three times faster still, though it remains a single-controller system.

More significant changes lurk around the back of the ix12. Dual redundant power supplies, a frequent request in this class, and variable-speed fans, surround four Ethernet ports. Each sports gigabit speed and the set supports Microsoft Windows MPIO, can be aggregated with 802.3ad, or used in VLAN configurations with up to 4 VLAN tags per port. The ix12 speaks just about every language, from NFS and SMB to AFP and iSCSI, and now adds WebDAV and DFS support, too.

A few limitations separate this new ix12 device from its enterprise-grade brothers, however. As noted, a single controller manages all access, so redundancy and parallel processing are limited. Although the ix12 sports 12 drive bays, it only has four SATA channels internally; each bay shares a channel with two others using SATA expanders. Don’t expect to push wire speed over all four Ethernet ports at once, even with all this newfound CPU power.

A Wall of Drives

Base ix12s ship with 4 drives installed, but we were disappointed to learn that additional drives must be purchased in 4-disk packs from Iomega. Although this decision is understandable, the ix series remains a holdout amid growing legions of bring-your-own-drive competitors. At least the company supports mixing and matching drive sizes, including 1 TB and 2 TB at present. We suspect that the unit uses the same reliable 5900 rpm Seagate Barracuda LP drives as the ix4-200d.

Iomega added a few tricks to the LifeLine software to take advantage of a possible 12 drives installed. First up is the addition of dual-parity RAID-6 for improved data protection. The company (and this reviewer) suggest this over RAID-5 once more than 5 drives are combined in one set. Don’t worry, though, because RAID configuration can be changed online and any unused drive can be used regardless of its location in the array. The ix12 also adds drive spindown, saving power when the RAID set isn’t in use.

Like the ix4, any portion of a RAID set can be carved out into an iSCSI LUN for Ethernet-connected hosts. Iomega claims that LUN provisioning times have improved with the added horsepower and software tweaks, and we hope this is true. A maximum of 256 LUNs can be configured in this way, though even 12 drives are unlikely to drive much performance to that many storage users.

Where to Use It?

Although not listed yet, Iomega promises that the ix12 will have a place on the Exchange ESRP, Windows Server and Hyper-V logo list, and VMware Compatibility Guide this month. It’s already the first Iomega product to be “EMC E-Lab Tested”, meaning it is on the EMC Support Matrix; this fact alone speaks volumes of EMC’s expectations for the unit. My own experience shows that Iomega iSCSI is fine for smaller VMware and Hyper-V deployments.

Clearly, the ix12 is a new kind of Iomega array. If the 200d and 200r were a sign that the company wanted to move out of the house, the ix12 is a demonstration that they have graduated. Starting at US $5,000, the ix12 is all business and its resume ought to impress in interviews. It can’t quite boast the scalability and redundancy of established arrays (including its brothers from EMC), but it ought to be an easy acquisition for companies looking for a little more storage here or there.

One is left with questions, though: How big will EMC let Iomega get? If 12 drives are acceptable, what about 24? Is SAS off limits? What about 10 Gigabit Ethernet and even Fibre Channel over Ethernet (FCoE) eventually? Can we dream of dual controllers? At some point, the Iomega lineup could even threaten the CLARiiON!

Then there is the competitive landscape. Iomega leapfrogged the 8-drive Data Robotics lineup and landed squarely in competition with the likes of the revitalized Overland Storage but at a much lower price. We also have Netgear, HP, Dell, and Promise, and there is an attractive D-Link box packing 15 drives and 10 GbE. Iomega also has to worry about its own big brother, the Dell/EMC AX4, starting around $12k. It’s a competitive market, and Iomega is in for a fight as even more vendors wake up to the possibilities in this market.

The Iomega ix4-200d is a sleek 4-drive SOHO RAID system that does just about everything, from NAS to Time Machine to iSCSI for a list price right around $700

Iomega is well into its second coming as EMC’s entry-level storage division. First, they applied EMC’s compact and full-featured LifeLine home storage software to existing gear, giving birth to the Home Media Network Hard Drive, StorCenter ix2, and StorCenter Pro ix4-100. Then they wooed the small-business community with the rack-mount StorCenter ix4-200r, adding iSCSI target support and VMware compatibility.

Today, they are back with the new ix4-200d, probably Iomega’s best product yet. It includes every feature of the rack-mount ix4-200r, including NAS and iSCSI target mode plus great new stuff like one-touch synchronization. All of this is packaged in a Drobo-like desktop system with a starting list price of just $700, or less than half the cost of a comparable ix4-200r!

Desktop Storage

External desktop storage products, exemplified by Western Digital’s wildly successful My Book series, have been a huge retail hit. Priced just over $100, these drives pack a terabyte or more and offer plug and play simplicity. I recently visited a small business with a WD or Seagate USB enclosure on every single desk. I’ve purchased five USB- or FireWire-connected hard drives myself over the last two years!

But these single-drive desktop wonders are a disaster waiting to happen:

• They fail frequently (like my Maxtor 3200), instantly wiping out the data they contained
• They are targets for thieves, so data loss prevention (DLP) experts warn against their use
• They aren’t shareable natively, so most people resort to sneakernet swapping rather than fight with Windows to present them as a network share
• When they’re full, they’re full, forcing the purchase of a whole new drive

Many vendors sell grown-up versions that address some or all of these concerns with multiple drives, network connections, and encryption, but these have been slow to catch on. Since they contain redundant drives and extra hardware and software, they are much more expensive than their little cousins. Iomega has done battle in this arena with their original StorCenter ix2 and the ix4-100, but these have yet to catch on. Even Drobo, with their fanatical user-friendly focus, has failed to convince many buyers.

Then there is the world of business storage. Way down at the bottom of the enterprise storage pyramid lies the realm of small 4- and 8-drive storage arrays. These SMB storage arrays offer a lot of capacity and reliability for the money but very little in the way of features. Iomega’s StorCenter Pro ix4-200r, in contrast, wowed the techies with a full iSCSI target stack that was certified for VMware ESX. But the price, over $1500, definitely limited sales to the home hobbyist.

“Just Right” Storage

Although the name is similar to the StorCenter Pro ix4-200r launched this Spring, Iomega went back to the drawing board for the ix4-200d. They built an entirely new device that could offer the impressive features of their StorCenter Pro line at a price closer to consumer storage offerings. The result boasts everything the Pro has and more at less than half the price:

• You want connectivity? The ix4 sports dual gigabit Ethernet ports that can be teamed up for performance or split off for redundancy.
• You want NAS? The ix4 supports NFS, SMB, and even Apple’s AFP, plus it’s Active Directory compatible.
• How about iSCSI? It’s a full-featured iSCSI target, certified for Microsoft Server 2003 and 2008.
• Want to host virtual machines? The ix4 is certified with VMware ESX 4 vSphere using both NFS and iSCSI, on the Xen HCL, and that Microsoft logo means it will work with Hyper-V as well.
• Need backup? The ix4 comes with EMC’s Retrospect and supports OS X Time Machine over AFP just like an Apple Time Capsule.
• Looking for weird features? How about support for up to 5 Axis network cameras, BlueTooth Picture Transfer Protocol, and UPnP/DLNA media service!
• Iomega also added a new feature, QuickTransfer, to synchronize files between devices.

This is one seriously feature-rich storage system. In fact, this glut of features is the ix4′s Achilles heel: How do you effectively communicate the value of a device that does so much? Most of the buying public has never heard of most of these features, so the price remains hard for some to justify.

Every ix4 configuration comes loaded with four hard disk drives

Another hurdle for the ix4 is Iomega’s decision to fill it with hard drives. One cannot buy an empty ix4-200d, and both the 2 TB and 4 TB configurations come loaded with four hard disk drives. This raises the price of entry and scares off the very techies who might be interested in the device. The majority of Drobos are purchased with no drives at all, and storage geeks like me love the idea that disks can be added as-needed in the future. Although Iomega is open to users swapping out the drives in their own StorCenter device, this is not its intended use case. Iomega’s decision to sell the ix4-200d as a loaded appliance seems counter to the price sensitivity and flexibility needs of buyers.

QuickTransfer: Data Synchronization for Everything

One nifty new feature included with the ix4-200d is QuickTransfer, a one-touch data synchronization capability. Leveraging rsync technology, but hiding this complexity with a more-friendly wizard-based GUI, QuickTransfer allows users to set up synchronization jobs between the ix4 and a variety of targets:

• USB drives can be plugged into one of the three USB 2.0 ports and synchronized with a subset of the content of the ix4. For example, a portable USB drive could be “recharged” with the latest set of data before one heads out of the office.
• Two Iomega ix4′s, or other NAS systems for that matter, can be synchronized over the Ethernet/IP LAN. This would provide a robust and bandwidth-friendly remote office backup or data replication solution.
• A PC or Mac can also be synchronized over a network share, providing a simple alternative to the bundled backup software.

QuickTransfer is exclusive to the ix4-200d for now, but Iomega assured me that it would be included in future StorCenter products and added to the StorCenter Pro ix4-200r in the near future. It is unknown if or when other existing StorCenter devices will get QuickTransfer, however.

Iomega’s Next Move

What will Iomega do next? They must be ready to announce their vSphere 4 and Microsoft Windows Server certification soon, since both company’s web sites already list the device in their compatibility lists. Iomega ought to try to take advantage of the interest among VMware users with a big VMworld splash. They will be there, but it is awfully hard to get noticed at such a large event. I am looking forward to the event to get a hands-on test.

The ix4 should begin showing up for sale at online stores very quickly. Amazon listed the rackmount product within days of its release, and we expect the same this time. But will Iomega offer this cheaper device in retail stores? It would be great to have it available at Staples and Best Buy, but shelf space for a storage system this expensive would be hard to get. Instead, expect it at specialty outlets like Fry’s and perhaps Micro Center.

How much does the StorCenter ix4-200d cost?

• The 2 TB model (SKU# 34546 with four 500 GB drives) lists at $699.99
• The 4 TB model (SKU# 34549 with four 1 TB drives) lists at $899.99
• The 8 TB model (SKU# 34563 with four 2 TB drives) lists at $1,899.99

It also seems likely that the 2-bay product is up for a refresh in the near future. The ix2 can’t be said to be very attractive, so hopefully the company will do something about this with the next-generation product. It is unclear whether the inexpensive 2-bay device will get iSCSI support, but I suspect it will. Beyond this, might Iomega move further upmarket with an 8-drive unit? We shall see!

Iomega has been a staple of the desktop computing environment for decades, but the company’s products have never been quite at home in even small corporate data centers. That changes today with the introduction of the iSCSI StorCenter Pro ix4-200r. As of now, EMC’s SOHO storage subsidiary is a serious challenger in the small business and entry-level VMware ESX storage market.

It might look like the existing NAS 200rL, but the ix4-200r sports upgraded hardware and a new rev of EMC’s LifeLine storage software. This unit packs a serious punch, boasting full iSCSI target support for servers running Windows or Linux (or anything else with an iSCSI initiator) in addition to NFS, SMB, media streaming, print services, and just about every other protocol.

Although both Iomega and VMware are under the EMC corporate umbrella, it was a surprise to find that the ix4-200r is certified compatible with ESX using both iSCSI and NFS right out of the gate. This is the only inexpensive storage system to wear a VMware badge, and this alone will likely make it a fixture in small offices and VMware labs. The desktop StorCenter ix4-100 and StorCenter ix2 are already widely used in these environments even without iSCSI, after all. The ix4-200r provides a complete SAN-in-a-box, supporting multiple NAS and iSCSI shares with dynamic allocation of the internal RAID-5 protected storage.

Although aimed at the office, the ix4-200r retains the vast set of LifeLine capability we’ve seen in Iomega’s other offerings. This includes media streaming for UPnP (Twonky) and iTunes (Firefly), remote access, Active Directory support, and print services. The new unit even packs the more unusual Axis video surveillance capture capability. It sports two USB ports on the back and one on the front for expansion, data import, backup, or printers as well. Probably the best software feature is EMC’s Retrospect backup client, which was recently updated on the Mac platform.

The ix4-200r starts at just $1,799 (list) for 2 TB, and I expect resellers to dip well below that number. For comparison, Amazon currently sells the smaller non-iSCSI desktop 2 TB ix4-100 for $675 and the 1 TB ix2 for $268 and I’ve seen each for much less. I expect a street price of $1600 for the 2 TB rackmount unit – competing products from Buffalo and Netgear are priced and marked down similarly. The 4 TB model is priced $1,000 higher, perhaps unrealistically high given that the only difference is the use of 1 TB hard drive units instead of the 2 TB’s 500 GB drives. For comparison, Drobo just introduced their limited single-server 8-bay iSCSI DroboPro at $1,750 configured with four 500 GB drives. But none of these alternatives boast a spot on the ESX compatibility list, and I suspect this may be a deciding factor for many. Note that you can’t buy less than four hard drives in an ix4-200r, though the drives are easy to replace.

Iomega was kind enough to give me a preview of the ix4-200r at their offices, and I came away impressed by the new array and the company in general. They have a solid vision of the needs of the small office and are hard at work on products to meet them. Although the iSCSI support is not coming to the company’s other LifeLine-powered systems (the ix2, ix4-100, and Home Media) at this point, I would not be at all surprised to see it become a staple in future networked storage systems. A large gap remains below the EMC CLARiiON range, so I suspect that larger Iomega systems are on the way as well. As a potential buyer, I’d like to see Windows logo qualification, and Hyper-V support would be super as well. And as a Mac user, I’d love to see Time Machine support and for Iomega follow Drobo by offering a free iSCSI initiator – a guy can dream, right?

Updates and clarifications:

• Iomega has added the StorCenter Pro ix4-200r to their web site alongside the non-LifeLine StorCenterPro 200rL
• The ix4-200r will not be released until April 22, 2009
• The new rackmount ix4-200r is listed at $1799.99 for 2 TB and $2799.99 for 4 TB. I don’t expect to see either sell for less than a few hundred off those list prices
• The ix4-200r has been listed in the VMware ESX compatibility guide for a few days now for both iSCSI and NFS connectivity – I’m surprised no one noticed!
• Although it’s not mentioned in the press release, Iomega tells me that the StorCenter Pro ix4-200r does still support the BlueTooth file exchange found on its little brothers

Iomega's StorCenter Pro ix4-100 is VMware certified, hot swappable, and not bad to look at!

As I expected, EMC’s Iomega subsidiary today rolled out the StorCenter Pro ix4-100 a big brother to the popular but plain StorCenter ix2 NAS device. This new model add hot-swappable drives (there are four now), RAID-5, and a longer warranty to make it suitable for small office use. It uses a blacked-out version of the chassis from the non-LifeLine StorCenter Pro 150d.

Like the ix2, the Pro ix4 is certified for VMware ESX using NFS. iSCSI is still absent, though EMC folks have talked about adding this in short order.

This is the third member of the LifeLine-powered NAS family from Iomega: The confusingly-named single-drive Home Media Network Hard Disk Drive, the dual-drive StorCenter ix2, and this four-drive StorCenter Pro ix4-100. The “-100″ nomenclature suggests that more 4-drive models might be on the way, perhaps a “-200″ model sharing its rackmount chassis with the existing non-LifeLine StorCenterPro 200rl.

With NetApp exiting the small-business market by ending their StoreVault line, who would have thought big old EMC would be the one to step up? At $799 or $1,299 for the 2 and 4 TB versions, the ix4 is about the same price as a Drobo, which is $749 or $999 plus $199 for the DroboShare NAS.

Zip drives like this 1996 parallel-port example made Iomega famous, but EMC is giving the company a second act

Pity poor old Iomega. The company responsible for hot products like the Zip drive and coulda-beens like the Clik drive was stumbling in the early part of this decade, unable to distinguish itself from all of the other providers of commodity external storage devices for consumers. Although the company had built the Zip into a viable floppy drive successor, USB “thumb drives” took that market by storm, replacing removable disks with flash memory.

The company was working to break into the small business market in the middle of this decade, offering Rev disk-based backup, small desktop and rack-mount NAS servers, and internet storage in addition to well-regarded software add-ins. But by that time, Maxtor, Seagate, and Western Digital had come to dominate the external USB drive market, and Lexar, PNY, and the like had taken over the removable world.

Then EMC stepped in with their March, 2008, $178 million buyout offer. Iomega rebuffed the offer at first, since it was in the process of being merged with China’s Excelstor. But after some apparently tough back and forth between the companies, Iomega finally accepted a $213 million offer in early April, completing the acquisition in June. Although it made sense for EMC to move down-market, as Cisco did with their similar Linksys acquisition, many wondered how this would work out, especially when one considers the contentious buyout process.

We needn’t have worried – ever since the EMC buyout, Iomega has rocketed forward, introducing intriguing new products, finding synergies within EMC, and gaining mindshare. Although they still peddle commodity storage, Iomega’s new line of EMC-powered NAS systems is getting the real attention (VMware geeks especially should take a hard look at the StorCenter ix2!) But the company ought to make a few marketing changes if it is to really succeed.

EMC Throws a Lifeline

Without a doubt, it was EMC’s LifeLine software that injected the most adrenalin into Iomega. Although it predated the acquisition, LifeLine is a perfect fit for Iomega: It’s a Linux-based NAS operating system with RAID, Retrospect backup, integrated media services (compatible with iTunes, Xbox, Wii, and UPnP), print services, and unusual features like Picture Transfer Protocol, Bluetooth, and Axis surveillance storage.

It’s a great combination of home features, and Iomega quickly launched a product including this software: the StorCenter ix2. Although Iomega had used the StorCenter brand name for years on a variety of NAS devices, the ix2 was the first to use EMC’s LifeLine software. The combination of Iomega, LifeLine, and Retrospect makes for a compelling home product, and many a “terabyte home” is switching to the platform. But the product’s inherited industrial design is plain (one blogger suggested it had a Wife Acceptance Factor issue), and the naming is confusing. A casual shopper would have no way of differentiating the various StorCenter products – indeed, it is difficult for me to figure out the various product lines from Iomega’s sales-oriented web site!

Predictably, Iomega is expanding their LifeLine-powered lineup both down- and up-market. The company recently introduced a smaller single-drive LifeLine-powered home NAS device, and we are hearing rumors of larger office-oriented versions. But the little guy also uses hand-me-down clothes, and is tagged with a mouthful of a name that is at once inconsistent and forgettable: Home Media Network Hard Drive. The average consumer would have no way of knowing what lurks under the skin of this home NAS, since it looks exactly like the basic USB-connected Prestige line! Why can’t the company that gave us the pretty eGo drive design something a little more attractive – check out what the competition is offering!

Moving On Up

Although their home-oriented offerings are compelling, VMware geeks should keep their eye on the upscale uses of the LifeLine platform! It hasn’t been officially announced, but EMC folks are saying that iSCSI will be added to LifeLine in short order. And the platform is already VMware certified!

Interested in building your own VMware lab? Pick up an ix2 and use NFS until the iSCSI software is added. It’s on the HCL, and makes an excellent platform for playing around with ESX! Plus, you can stream iTunes and store webcam video of your door at the same time!

Although the rest of the StorCenter line isn’t currently LifeLine powered, I’m sure it’ll be upgraded in short order. It might not be powerful enough for real enterprise computing, but a small office or lab would be well served by EMC’s kid-brother systems.

Although Iomega’s latest offerings are compelling, the company really needs to do something about its marketing. Ditch the bland and confusing names and cases and come up with something really compelling. Let buyers know which systems are LifeLine-powered and transform the web site from an online store into a site that draws attention to the unique features of these systems. Although EMC’s products might sell themselves, the consumer / prosumer / small business market is a tough one, as Iomega must already know.
