StarWind Virtual SAN configuration – pt.2

starwindvsanconfig01

Once the StarWind Servers have been deployed in the VMware cluster, the configuration of devices and replication is the next step of the setup procedure.

To provide HA and performance, StarWind Virtual SAN supports the following RAID configuration:

  • FLAT images – RAID 0, 1, and 10 (RAID 5, 50, 6, and 60 all-flash arrays only)
  • LSFS –  RAID 0, 1, 10, 5, 50, 6, 60

Volumes can be separated in two possible ways. OS and StarWind Device images can be kept on a single physical volume using partitions (GPT recommended for the shared storage to allow volumes bigger than 2 TB) or segregate the OS to a dedicated RAID 1 array.
