ESX 5.1.0 IPoIB NFS datastore freezes
Hello, hopefully this is the right place to provide some information about a VMWare IPoIB datastore freeze. We are testing a new VMWare ESX 5.1.0 setup. Sadly we have only 3 ConnectX (gen 1) cards...

Also... i've seen before certain machines that do not support SR-IOV. this function also needs to be supported by the HW. you need to check with your server vendor.

I got a question about the SX6018 switch and any input would be greatly appreciated. Will the FDR ports auto-negotiate down QDR and work with ConnectX-2 adapters? Thanks!

are you running the SM from the hypervisor host machine? if yes, can you try running the SM on a regular machine?
View ArticleRe: Management command failed in KVM for SR-IOV
your SM is running on the older HCA type (MT25208) - which should be just fine but still i am thinking about maybe try to run it on a newer ConnectX card (you few of those out there).

Shouldn't be a problem. the Infiniband spec defines backward comparability. What are you planning on running between those nodes?
