Introduction

  • PowerStore can create point-in-time snapshots of one or more volumes. Snapshots are space-efficient because they consist of pointers to frozen data blocks and use redirect-on-write technology. They consume no extra space unless, for example, a thin clone is created from a snapshot and mapped to a host, and new data is written to the thin clone.

    Snapshots can be created manually or automatically using snapshot rules within protection policies. For snapshot cleanup, a service runs hourly in the background in PowerStore and removes any expired snapshots.

    Hosts cannot access snapshots unless a thin clone is created from the snapshot and presented to the host.

    For information about protection with replication, see Dell PowerStore: Replication Technologies. For additional information about metro volume witness in a non-Oracle environment, see the white paper Dell PowerStore: Metro Volume.
