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 article, Storage Fixes in VMware ESX Server 3.5 Update 2.

Update 3 is not as important from a storage perspective, but there are some goodies in there:

• New VMDK recovery tool (nifty!)
• Storage tweaks like fixed multipathing on IBM SVC, interrupt coalescing on QLogic 4 Gb FC HBAs, and some bug fixes
• Expanded support for SATA (but not for VMFS), SAS, and some Broadcom NICs (but still no TOE)

Beth Pariseau over at SearchStorage.com has another great interview, this time with “Mr. SCSI”, Larry Boucher of Alacritech. Despite being early to market with TCP offload engine (TOE) Ethernet NICs, and iSCSI HBAs in particular, the company has been less successful than many would have expected. This is probably because most folks just didn’t use ‘em - iSCSI works fine with a plain-Jane gigabit NIC on today’s modern computers.

Boucher suspects (as do I) that 10 Gb speed will make TOEs much more critical, and he expects Alacritech to be well positioned to take advantage of this shift.  He sees TOE becoming integrated with future PC chipsets, and not just for storage.  Asked when he expects “the year of 10 gigabit” to come, Boucher estimated 2009.  Sounds reasonable to me!
