Ok so question for the ib users on the forum. I recently installed 3 mellanox connect x-2 EN adapters 2 in VMware esxi 5.5 hosts and 1 in a server 2012 R2 storage back end. After plugging in the cables and configuring the ip's for the point to point setup everything just worked.
I even plugged the 2 esxi hosts into each other and used the infiniband NICs as vmotion network and again it just worked.
The reason I'm confused is because from what I read at a minimum I thought I would need either an infiniband switch or software to run as a subnet manager but i didn't It all just worked like a normal nic.
Question:
1. Do you not need a subnet manager for 10 gig Ethernet infiniband adapters?
2. I swore I read end to end I finiband in esxi 5.5 wasn't possible yet because the software that ran the subnet manager didn't work on esxi 5.5 (it works on 5.1) is that not true?
3. Is there some limitation to these cards just working as normal NICs without any extra software besides the drivers?
If I knew I could just use these cards without any extra headaches I would have purchased 3 more instead of my expensive 10 g Intel NICs for the storage back end.
Thanks guys
