I too have been using AoE for a while now (almost 4 years), and it's been rock solid for us, and much more resilient than any of our iSCSI implementations...or DASD for a lot of boxes. Coraid has started producing HBA's that you can use with VMWare, we haven't tried those yet but we have used the Windows HBA's and been very happy with them so far.

Sure, because vmware doesn't support AoE afaik. You don't have much choice.

AoE has been far more stable for me than any of the various iSCSI
target/initiators I have deployed. It is just dead simple. There really isn't
much to go wrong with it.

It is FOSS. Anyone can support it (not that I have ever really needed much
support in my 4 years of using it). It is in the standard kernel distribution.
Various people have written their own AoE targets even.
I buy Supermicro boxes, put disks in them, bond dual gig-e interfaces, create
an LVM volume group, point vblade (FOSS AoE target) at the VG and let my Xen
dom0's running cluster-lvm slice up disk and install virtual machines. I have
deployed several dozen of these. This has worked great for years now. You don't
necessarily need Coraid or much of any real support.
