VMware ESX FCoE CNA Compatibility in Plain English

Converged Networking Adapters like this QLogic 8242 are all the rage, but which are supported in VMware ESX and which have the broadest coverage of DCB features?

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

Do you want X-series or P-series storage? Is A-series networking gear any good? And where did all these HP products come from?

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

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

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?

The pistol shot heard this week was the starting gun for FCoE, not the execution of 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

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

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

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, [...]

Emulex and QLogic Learn to Speak Klingon!

Well, not exactly Klingon, but both Host Bus Adapter powerhouses chose today to announce 8 Gb/s Fibre Channel HBAs. This would be somewhat more exciting if there was any device these high-speed adapters could speak to. But switches, arrays, and drives are still a ways off. So for now, Emulex and QLogic can only speak [...]
