W. Curtis Preston launched his own series of Backup Central Live! seminars for 2011

Last week, after the Exec Event in Palo Alto, I joined my friend W. Curtis Preston for his first Backup Central Live! event. Curtis has spent years educating IT pros about data protection, this was the first week of a new series of self-produced events. And let me tell you, although I’ve seen him present dozens of times, Curtis was really in his element here. He held the packed room enthralled, and the vendor sponsors I talked to were very pleased about the event!

Introducing Backup Central Live!

The Backup Central Live! series are day-long seminars across the USA in 2011. Each event includes over 3 hours of content from “Mr. Backup”, W. Curtis Preston, as well as presentations from Jacob Farmer and the sponsoring vendors. The seminars are free for qualified end-users, which includes most of the readers of this blog!

Curtis and company will cover the challenges of backing up and recovering data in a variety of settings:

• Virtualized servers (e.g. VMware, Hyper-V, Xen)
• Very large servers and data centers
• Remote offices and laptops
• Data retained for multiple years

The session also includes technical detail about key products and technologies:

• Cloud Backup Services
• Deduplication
• Continuous data protection (CDP) and near-CDP
• Archive software
• Tape and its proper role

Attendees even get free breakfast and lunch, which was of a good hotel caterer quality in my opinion.

The Backup Central Live! crew does a great job putting together a professional event

I knew Curtis could put together quality backup content, but the crew deserves credit for such a professional and successful event. They attracted some great sponsors, too, including AppAsure, Aptare, FalconStor, NEC, Quantum, Spectra Logic, and Cirtas. And Jacob Farmer’s involvement was a pleasant surprise, too: I’ve always enjoyed the deep technical conversations I’ve had with him!

If you enjoyed my own backup, archiving, and storage seminars in the past, I know you’ll love this event. The next Backup Central Live! cities are as follows. If you’ll be around, you really ought to attend!

• Orlando, FL Feb 1 Register here
• Houston, TX Feb 8 Register here
• Chicago, IL Feb 22 Register here

My only suggestion for the crew is that they get a bigger room next time!

This is the second entry in my Top-Ten in Storage series.

Not every innovative product can succeed in the market, and no matter how good some ideas seem, they can fail to make much of an impact. The truth is, people buy solutions, not technologies.

This list includes products so cool, so ahead of their time, that they just couldn’t fail. But they did.

1988 EMC Orion/Allegro

EMC’s RAM-based storage array predated and presaged its Symmetrix, offering lightning-quick I/O for very small workloads. But the Orion had a few serious drawbacks: It was astonishingly expensive, offered tiny capacity, and was never available for open systems. EMC’s initial offerings in the open systems market, Centriplex and Harmonix, also deserve mention though the company proved its worth with its “best” Symmetrix a few years later.

1985 3COM 3Server

I’ve written about the 3Server before, but let’s sum up: Before RAID, SAN, and NAS, and even before NetWare and NFS became entrenched, 3COM introduced a flexible multi-disk network storage and print server called the 3Server. It was an innovative combination of hardware and software, but it lost out to NetWare on open PC hardware in the market. Although the 3Server lasted just a few years, it made a lasting contribution to the field: Its 3+Share software became 3+Open, then LAN Manager, and was finally absorbed by Microsoft to become SMB/CIFS.

HP AutoRAID (High Availability Disk Array Model 12)

The first post-RAID virtual sprang fully-formed from the big brains at HP to challenge the industry-leading modular offerings from Data General’s CLARiiON and DEC/Compaq’s StorageWorks. It one-upped everyone with automatic relocation of LUNs between different RAID levels based on workload about a decade before Compellent, EqualLogic, and 3PAR had anything of the sort. But the AutoRAID had two key drawbacks: Like mama bear, it wasn’t big enough for big companies but was too big and expensive for little ones, and it was SCSI-only (though a Fibre Channel bridge was a common accessory). Some of the concepts lived on in the HP EVA line, but AutoRAID didn’t last long.

Microsoft Object File System (OFS)/Relational File System (RFS)/WinFS

Microsoft shoulda-coulda-woulda revolutionized file storage with nearly every major operating system release. It looks the same every time: A database/filesystem hybrid that would add structure to the vast unstructured file world. Despite the hype, we haven’t seen it yet. 

MangoSoft Medley

Consider the typical LAN: Lots of clients with lots of hard drive space connected to a server with yet more disk capacity. Wouldn’t it be nice if the space on these clients could be used as a virtual network server? Well that’s just what MangoSoft announced in 1997, gaining much attention in the PC press. Sadly, the idea never really caught on, although MangoSoft continued. But distributed network storage has become the industry’s Brigadoon, trotted out as a new idea year after year.

StorageNetworks

This is my flop – I worked for StorageNetworks from 1999 through 2001.

StorageNetworks was launched in 1998 to provide off-premise storage and backup as an on-demand service for enterprise customers. They sought to take advantage of the emergence of high-speed Fibre Channel connectivity over metro distances to commoditize storage capacity. But only Houston (where I worked) had an acceptable infrastructure for the service, so the company changed focus to hosting centers. Then off-site backup. Then software. Nothing worked apart from vendor-independent services, and the (now public) company was shy to base its revenues on that. StorageNetworks was gone in 2003, but does the service remind anyone of Amazon S3 or Nirvanix? Maybe it was just ahead of its time.

Compaq VersaStor

Announced in 1999, VersaStor would have been a revolution in Fibre Channel SANs, a full out of band virtualization solution leveraging specialized HBAs directing traffic. It was continually pushed back, finally being “merged” (after Compaq) with HP’s StorageApps in-band SANLink to become CASA. But then EMC sued HP over virtualization patents, derailing CASA, and the whole mess was permanently shelved at the end of 2003.

IBM Ice Cube/Collective Intelligent Bricks Hardware

IBM rocked the storage press in 2003 with their announcement of Almaden Research’s Ice Cube concept. Instantly dubbed “Lego brick storage” (trademarks be damned!), the storage units could be stacked in two dimensions, scaling without limit. Coolest of all (literally), the bricks were chilled with water! Although the concept progressed, we still haven’t seen it. But this didn’t stop Seagate from developing a similar concept, ISE, which is now Xiotech’s main offering. IBM’s Storage Tank and VSS could have been nominated, too, but I’m not a sadist.

Revivio CDP

Revivio was the pioneer of continuous data protection (CDP), with great technology and people. But no one (other than Symantec, eventually) bought it.

Pirus

Little Pirus was working on a small but scalable virtualized target when it was acquired by Sun in September of 2002. Their technology was launched as the StorEdge 6920, a mini alternative to the HDS USP in 2004, but (according to insiders) it didn’t exactly light the world on fire. Sun finally pulled the plug on the 6920 in early 2007, with HDS taking over continuing support for anyone who bought the moribund product.

Spun Down

Although ZFS’ universal storage pool with non-RAID is a great concept, it stands in the way of at least one (sometimes) desirable storage technique: disk spin-down. Put simply, since every disk contains metadata, all disks must always be spinning. This issue is by no means a ZFS-only problem, though – certain vendors tout the (laughable) greenness of their storage systems, while hoping that the average user won’t notice the truth: That a disk simply cannot spin down while any part of it is in use. This means that tacking spin-down onto a regular storage array is like painting it a different color: There is no benefit whatsoever to the average user. Sure, a few non-provisioned drives might spin down, but what are you doing buying a lot of non-provisioned drives anyway?

The solution has always been right in front of everyone: Develop a new type of non-RAID with enough intelligence to allow drives to spin down when not used. This is what COPAN Systems did with their MAID technology: Invent an entirely new storage array, with integrated data protection and management techniques that allow alive but not active drives to spin down. Spin-down is not MAID any more than a bicycle is a Ducati.

Let’s make one thing clear: It’s really hard to reduce the power demands of storage devices. Disks guzzle watts like few other data center devices, and enterprise storage uses lots of disks. Lots of vendors are looking to hop onto the green storage bandwagon, and they all seem to realize that bringing some intelligence to power management by enabling spin-down is an open door. But it’s awfully hard to maintain performance and data protection when disks are spinning up and down all the time.

One element of the greenByte story is the way in which they have tweaked ZFS to allow disks to spin down. They limit the metadata updates to just a few disks, so the others can be idled when no access to them is made. The company suggests scheduling this for off hours to minimize latency as drives are brought back online, an approach that is less than optimal from an energy perspective but demonstrates that they understand just how difficult this problem is to crack. The core is there, however: They have integrated the data protection and storage management elements to enable spin-down to be practical.

Compressed

Another major storage industry theme of the last few years is deduplication of data. An advanced (or devolved, depending on your perspective) form of compression, deduplication allows a storage array to store duplicate data more efficiently, reducing the amount of capacity required for some applications. Data Domain is top-of-mind in this space, but just about everyone now offers some form of deduplication technology.

One major roadblock on the way to deduplication (or compression) nirvana is performance. Simply put, it’s really really hard to process data on the fly without affecting performance, especially as data scales up to the multi-terabyte range or as systems scale out to include multiple devices. One approach to tackling this issue is post-processing dedupe, which accepts incoming data in the normal way but goes back and processes it later to remove duplicates. This is the method NetApp uses, and they have leveraged it to become the first vendor to support deduplication of production applications.

Predictably, deduplication is another technology integrated into greenBytes’ “ZFS+” technology. They claim that they can handle inline compression at wire speed, and also claim deduplication inline. It’s not yet clear exactly what the difference between compression and deduplication is to the company, or just what kind of performance their inline technology will yield, but it’s certainly nice to see this tech integrated with ZFS!

Thin is In (the House!)

greenBytes gets closer to enterprise storage bingo by adding thin provisioning to the mix. Actually, as the company’s CTO was quick to point out, they had to offer virtual or thin provisioning to enable the rest of the system to function. When your storage is sliced and diced by their Cypress array, the only way to present storage is with a wink and a promise of capacity to spare. Thankfully this is not the core of their pitch, however.

The company also promises snapshots and CDP replication, all leveraging ZFS at the core. All they need to add is tier-0 solid state storage to get five chips in a row without even using the free space! Although greenBytes is using Sun’s Thumper chassis currently for their Cypress array, their core technology is the ZFS+ software, and I expect we might see this mixed quite differently in the future. This is a software company, not an array vendor.

All considered, greenBytes has thoroughly broken the link between physical and logical storage, and I applaud them for it. This is exactly the kind of storage revolution the industry needs right now.
