• Using DPM servers for tenant backup

    By default, the CPS installation process provisions eight tenant DPM servers per rack that can be used for tenant backup. These servers are deployed to the compute clusters and use the naming convention DPM-TenantVM-0# (-01 through -08 on the first rack, -09 through 16 on the second rack, and so on). All of these DPM servers are pre-configured and ready to protect.

    To provide spindle isolation and to keep backups on a separate pool, one storage pool on each rack is assigned for backup. This backup pool is configured as dual parity to maintain N+2 redundancy and has total usable capacity of 115.2 TB. Each tenant backup DPM server is provisioned with 20 TB of allocated disk space (20 VHDs of 1 TB each) that is provisioned on 15.4 TB of physical space. This difference between allocated and physical disk space is addressed by data deduplication that runs on the backup pool.
