Initial use case is to toss a few storage servers on it for cifs hosting. It makes sense that write performance would be slightly lowered to maintain speeds for many users but we did expect more with how many hosts/DGs we have (and with optane soaking up all the writers).
Should we stripe or...
Not happy to see this thread. Just deployed a relatively large VSAN cluster and we’re seeing abysmal write speeds.
7 hosts, 14x PM883 3.84TB capacity disks and 2x P4800X 750GB cache (per host).
Crystal disk mark shows under 1GB on the SEQ4K.

there must be something wrong...
Fairly quiet. I ran it on my desk when testing an all flash setup and it wasn’t very noticeable. If I thought I could capture the sound in a video clip then I’d suggest sending one to you but I don’t think it would come through.
