Available datwsheet single and dual controller models, the DS scales in capacity to support a total of 48 hard disk drives by using the EXP expansion unit. DS comes standard with 4 storage partitions. Expansion Unit Step 3: Now the host systems can only access their assigned logical drives, just as if these logical drives were locally attached to them. VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive.

Storage partitioning adds a high level of flexibility to the DS Storage Server. The Obm premium feature allows for up to VolumeCopies.

You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive.

DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data backups and increased data protection. That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server.

Allows for up to 4 FlashCopies per volume. As opposed to FlashCopy where only the original values of changed data are copied to the repositorythe whole source logical drive is copied to target.

Back to Top Step 9: Ibj to Top Step 2: Back to Top Step 4: Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems. Therefore, the access to that LUN is exclusively reserved for that host. As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies. TD Back to Top Step 5: While establishing the copy, the datashfet logical drive will be in read-only state.
