Configuring a Dell™ EqualLogic™ PS Series Array as a Backup Target for CommVault™ Simpana™ Executive Summary IT managers are concerned that traditional backup methods aren’t keeping up with the needs of the business. Existing backup and recovery operations often fail due to media management issues and human error associated with legacy tape backup methods. As data continues to explode within corporate environments, IT is having trouble meeting backup windows with standard tape-based solutions.
Configuring a Dell™ EqualLogic™ PS Series Array as a Backup Target for CommVault™ Simpana™ Prerequisites This paper assumes that the DL Backup to Disk Appliance has already been configured and that the desired volumes on the EqualLogic PS Series Array have already been created and made available to the DL Backup to Disk Appliance by a SAN Administrator. The following table lists the minimum software versions required to support an EqualLogic PS Series Array as a backup target.

Configuring a Dell™ EqualLogic™ PS Series Array as a Backup Target for CommVault™ Simpana™ Once this ACL entry is created, on the protected server, a new entry with the suffix ‘vss-control’ will be present in the list of targets in the Targets tab of the iSCSI initiator properties. For each volume on which the data that needs to be protected resides, ensure there is sufficient Snapshot Reserve free space.
