Pinned topic Configuration check for my StorWize V7000 GEN3 with NVMe Flash drives

‏2019-05-26T09:16:06Z | gen3 power9 v7000

I have on the floor a brand new IBM Power9 paired with IBM StorWize V700 GEN3 filled with NVMe Flash drives.

Configured the SAN with DRAID6 with 2 rebuild areas, my goal is to make sure the SAN can sustain two simultaneous hard drive failures (similar to Traditional RAID10).

I also wanted to make sure I have configured everything correctly to maximize the performance of the SAN. I do not need compression or duplication right now, so not enabling those on the volumes that are being mapped to the host.

Below is the configuration dump....
