Faster Ethernet Gets Weird

Faster Ethernet Gets Weird

“One size fits all” doesn’t work for Ethernet, but this proliferation of speed options sounds like trouble without automatic capability negotiation. It’s nice to have options, but the IEEE must remain focused on interoperability and rein in the interests of the various companies proposing next-generation Ethernet technologies.

EMC VFCache (aka “Project Lightning”) Is One Small Step, But an Important One

EMC VFCache (aka “Project Lightning”) Is One Small Step, But an Important One

EMC VFCache (née Project Lightning) is a fairly simple offering: A server-based PCIe flash card that acts as a read cache with no integration with storage arrays or hypervisors. But EMC’s entrance into the host-based flash storage market is a powerful demonstration of the wave of disruption caused by flash-based storage and high-performance computing.

VMware ESX FCoE CNA Compatibility in Plain English

VMware ESX FCoE CNA Compatibility in Plain English

VMware has one awesome hardware compatibility list, but its thoroughness can be daunting. It’s fairly easy to search for a specific piece of hardware, but it’s difficult to tell what’s supported in a general sense. I’ve boiled down certain key hardware categories into a general plain-english list of what’s in and out of the ESX HCL. Let’s kick things off with FCoE CNAs.

Stephen’s HP Product Line Decoder Ring

Stephen’s HP Product Line Decoder Ring

HP has always been an alphabet soup company, assigning just about every item in their bewildering array of products a unique product number. Like Mercedes-Benz cars, even the product names are a mix of letters and numbers that can be off-putting to browsers. Now that they have grown to supersize proportions through internal expansion and acquisition, just about everyone outside the company seems to have trouble decoding the product line, so I decided to take a stab at decoding the enterprise lineup in plain english.

Storage Changes in VMware ESX 3.5 Update 4

March 31, 2009 By Stephen Leave a Comment

Like clockwork, VMware has cranked out another update to their flagship enterprise product, ESX 3.5. The last update came out in early November, 2008, and included some major new functionality. What’s in store this time to intrigue storage folks? Not much. For more information on earlier updates, see my articles: Storage Fixes in VMware ESX […]

Storage Changes in VMware ESX 3.5 Update 3

November 7, 2008 By Stephen 3 Comments

Just over three months after releasing Update 2 for ESX 3.5, VMware has released Update 3. That last Update brought major storage changes like VSS support, hot VMFS extension, Storage VMotion across Fibre Channel and iSCSI, and support for 10 Gb Ethernet and 8 Gb FC support. For more information on Update 2, see my […]

Is the FCoE Starting Pistol Aimed at iSCSI?

Is the FCoE Starting Pistol Aimed at iSCSI?

To hear this week’s storage industry news reports, one might think that Wagner’s fat lady came to Storage Networking World (SNW), singing her song as the iSCSI world collapses. Storagebod wonders what iSCSI’s death will look like. Chris Mellor at The Register says “Game Over” as NetApp, QLogic, Emulex and VMware join EMC and Cisco in singing the […]

QLogic and Emulex Deliver 8 Gb Fibre Channel For VMware ESX

July 30, 2008 By Stephen 1 Comment

As I mentioned on Monday, VMware’s Update 2 for ESX 3.5 includes support for 8 Gb Fibre Channel HBAs. This is an important development, so I went looking through the official ESX I/O Compatibility Guide to see which HBAs in particular were supported, but none were listed. This was pretty puzzling, but Rich from VM […]

Storage Fixes in VMware ESX Server 3.5 Update 2

July 28, 2008 By Stephen 5 Comments

VMware just released Update 2 for VMware ESX Server 3.5 (Virtual Infrastructure), and it includes some storage fixes of note: Support for Volume Shadow Copy Service (VSS) for filesystems Windows Server 2003 and Windows Server 2008 guests.  This means VMware services like VCB and SRM can now signal Windows Server to quiesce filesystems before creating a […]

Reacting to TechTarget’s Storage Products of the Year

February 11, 2008 By Stephen Leave a Comment

TechTarget’s Storage magazine today announced the winners of their annual Products of the Year awards, and it’s an impressive array of technologies. Although I did not contribute to the voting this year, I heartily endorse the outcomes! Overall, I was impressed with many of these products this last year, but certainly CommVault, HDS, ProStor, Xsigo, […]
