That’s a messy hole I went down and with no confirmable configurations I went with SAS SSD in my 7910 vSAN cluster using HBA 330’s. Using winsat in a windows VM to test disk speeds I get: Random 16.0 Read: 310MB/s Sequential 64.0 Read: 2892MB/s Sequential 64.0 Write: 1882MB/s
I’m finding it hard to complain and it was a much less risky solution.
