I'm just looking for an update on VCB support for multipathing on the proxy. I know it wasn't supported on ESX3.02 but I see no mention of whether or not it is supported in the documentation for 3.5 Upgrade 2.
I believe VCB has supported multipathing since the 3.02 days. I've been running MPIO drivers and multiple paths for at least six+ months now. BTW, I've only recently upgraded to ESX v3.5
Here's the official scoop: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2195414
