Storage Policy

A Storage Policy configures local disk layout on UCS servers: RAID drive groups, virtual drives, and M.2 boot drive configuration. It is applied to servers via a Server Profile Template and determines how physical drives are presented as storage volumes.

Examples

Example-1: The example below demonstrates a storage policy that creates an M.2 boot drive and a RAID-5 data volume from drives in slots 1–5.

compute:
  intersight:
    organizations:
      - name: MyOrganization
        policies:
          storage:

                controller_slot: MSTOR-RAID-1
