Hi Dexterous,
I have the Apple version of the vTrak e610f and would like to provision it to use it with ESXi 5.1.
Promise tech support mentioned that they have a beta firmware release that's not on their website for the vTrak e610f, its version 10.07. Have you tried that one with ESXi 5.1 by chance?
Since you're a reseller, can you give me your contact info. I'd like to acquire the vTrack e610f chassis for the channel sku firmware so I can switch it over and use it with ESXi 5.1.
Thanks, Jonathan
