Are You a Hypervisor Hugger or a Storage Stalwart?

Do you "heart" virtualization?

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.

Multi-Hop FCoE Is Not Ready For Prime Time (Yet)

This big V8 is a "mild hybrid", delivering some of the benefit and all of the feel-good without changing the world...

I know that a number of FCoE-related standards are settled, and I know that there are products in the market and even some limited multi-vendor compatibility. I even accept that some customers are deploying real “Full Monty FCoE” in production. But I just can’t recommend that technology yet: It’s not prudent, widespread, and low-risk, so I say it’s not ready for prime time.

Why I Am Biased Against FCoE

This Is Storage

I am biased against FCoE because it’s too new to be blithely and broadly recommended for production enterprise use. That’s all. Yes, the standards are standardized and there are products extant. But that’s not enough for me.

Alas, VMware, Whither HDS?

Where is HDS in VMware's roadmap?

If VMware aims to transform storage presentation, and is working with major storage vendors to make it happen, HDS ought to be part of it. Their history, technology, and market position earn them a spot in the “VAAI Cabal” and their omission was a bombshell to industry-watchers like me.

Seagate Jumps Hitachi’s Density Record With 4 TB Hard Disk Announcement

Hard disk drive capacity continues to increase at breakneck speed

Earlier this week, Hitachi GST (soon to be part of Western Digital) announced they would soon ship a 1 TB single-platter hard disk drive. But archrival Seagate rained on their parade financing immediate shipment of their own 4 TB unit. With the industry consolidating rapidly, it’s good to see healthy competition among the two remaining hard disk drive giants.

Mac OS X Lion Adds CoreStorage, a Volume Manager (Finally!)

CoreStorage implements a full complement of data structures but uses them in a very simplistic manner currently.

Mac OS X was majorly deficient in that it lacked a volume manager. This wouldn’t seem like a big deal to the average user, but held back the operating system in so many ways. A volume manager brings storage virtualization to an operating system, allowing storage capacity efficiently to be managed and manipulated. But all this has changed in Mac OS X 10.7 “Lion” with CoreStorage.

The Transformation from Data Robotics to Drobo

Drobo CEO Geoff Barrall gives Gestalt IT Tech Field Day delegates a sneak peak at the new Drobo S and DroboElite

Data Robotics spent the last year transforming itself from a maker of expensive consumer storage devices to a player in the nascent small enterprise storage array market. That process took another step this week, as Data Robotics officially renamed itself Drobo. It is ironic that the company would shed a longer, corporate sounding name for the familiar consumer product designation, but there is no denying the power of the Drobo brand.

Defining Failure: What Is MTTR, MTTF, and MTBF?

MTBF is the sum of MTTR and MTTF

Most computer industry vendors use the term “MTBF” rather indiscriminately. But IT pros know that systems do not magically repair themselves, at least not yet, so MTTR and MTTF are just as important!

Not All 802.11n Networks Are Alike

802.11n is a package of enhancements, most of which are optional

Buyers of 802.11n wireless network equipment should not assume they will see a great benefit right out of the box. Most will have to enable by hand a high-performance configuration including wide channels and 5 GHz operation. And some client devices may never reach the levels of performance expected by consumers due to hardware limitations.

FCoE vs. iSCSI – Making the Choice

iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade, while FCoE is likely to take over in high-end enterprise shops

iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade. FCoE, on the other hand, is likely to take over in high-end enterprise shops. It is relentlessly promoted by major vendors, and it seems that they will force the upgrade eventually.
