[gpfsug-discuss] Virtualized Spectrum Scale

[Aaron Knister]

Hi Greg,

I'm rather curious about your srp difficulties (not to get too off 
topic). Is it an issue with srp by itself or the interaction of srp with 
the SRIOV IB HCA? We've used SRP quite a bit both virtualized and not 
and have seen good results both in terms of stability and performance.
