SRP initiator 1.8.2.4 on ESXi 5.x show me a good RDMA performance.
But upgrade to ESXi 6 or above - include ESXi 6 update 2 with latest patch - then it show me a PSOD (Purple Screen Of Death) with APD (All Path Dead) randomly.
Why this problems occurs with COMSTAR target on Solaris families include OmniOS, Nexenta, etc.
IPoIB iSCSI also unstable.
I have a 2 of SX6036G VPI Gateway Switch then change all of MCX354A-FCBT's operation mode to Ethernet with mlxconfig then connect to OmniOS IPoIB iSCSI Target via VPI Gateway.
I'm also heard that Mellanox will not support Infiniband iSER on ConnectX-3 or belows from some sources.
What's your long term support policy?
If you drive Ethernet RoCE - RDMA Storage Protocol include - in virtualization then just say it!
I can't remember how many times to wait for support RDMA storage protocols for every new ESXi.
Best Regards.
