Hi,

1. Install the ESXi host on one SAS drive.

2. You can create diskgroup using SSD and MDs , each disk group should have one SSD and max upto 7 HDD (total 8 devices).

3. Recommended to have 3 or more host in the cluster.

4. Do not create RAID at hardware level, let it be passthru.

5. At the VSAN level you can create a policy of FTT =1 , which has one mirror component for each object. So that one host failure can be tolerated. If you have more hosts in the cluster, you may increase the FTT value to have more copies for redundancy.
