Can ESX 3.5 emulate SCSI‐3 disk reservation protocol?

Can ESX 3.5 emulate SCSI‐3 disk reservation protocol? I mean I can install Microsoft Windows 2008 cluster with ESX 3.5? Or ESX 3i?

My Windows 2003 Clusters are working since December 2007 on ESX 3.5 pretty smooth I can say...the problem now when I check the requirements for Windows 2008 cluster it said: "Disk bus type does not support clustering".

"Working" and "Supported" are two different things. And yes its still SCSI-2 on ESX 3.5.

I don't believe clustering (MSCS) is supported on 3.5 or 3i, regardless of Windows version.

I'm pretty sure that the SCSI controller in an ESX VM still only supports SCSI-2 so you would have to use the MS software iSCSI initiator from within the cluster VMs to get around this for Windows 2008.

Thank you for the answer. So I will need iSCSI SAN to build a Windows 2008 cluster. Are there some plans to support SCSI-3 reservation protocol in the next version of ESX?

Finally you post the correct answer: ESX 3.5 supports just SCSI-2.

BTW, I asked if I can install Windows 2008 cluster on ESX 3.5 or ESX 3.5i, not if it's supported...
