About moving a storage partition for better performance

This section describes how to move a storage partition from a base unit to an expansion disk. If all or a part of your MSDP partition resides on the Appliance base unit (base disk), it is recommended that you move the MSDP partition to an expansion disk. This applies to 52xx appliances and is needed for optimum performance. The base unit should ideally be used in case the external storage is full and you are yet to expand the storage to additional storage shelves.

While moving a storage partition from a base unit to an expansion disk the following guidelines should be considered:

  • To schedule high performance backups, it is recommended to move the AdvancedDisk partition or MSDP partition from the base unit to the expansion disk . For example, moving the MSDP partition would result in the backup to MSDP to span across 450MB/s and 850MB/s storage which leads to performance improvements.

  • The approximate time required to move 4TB from a base unit to an expansion disk is ~2.45hours on a light load system. This can be considered as the basis to calculate the time for moving additional TB of data.

  • The amount of data being backed up should be limited when moving a storage partition. If the backup is not limited the time required to move a partition can increase and be double the actual time required. The best practice is to limit the backup coming in during the move, if this precaution is not taken the time to move 4TB the move can increase up to 5 hours

You can move a storage partition using the following options:
