Because they both require a different distribution of OFED, which are mutual exclusive to install.
in theory if you deploy plain OFED it might work, but that will be hard to find somebody to support.

    I must admit, I'm curious as to why one cannot use GPFS with IB and OPA both in RDMA mode. Granted, I know very little about OPA but if it just presents as another verbs device I wonder why it wouldn't "Just work" as long as GPFS is configured correctly.-AaronOn 9/19/16 3:11 AM, Vic Cornell wrote:> Bump>> I can see no reason why that wouldn't work.
