Storage partitioning adds a high level of flexibility to the DS Storage Server. The DS comes with a 3 year, parts and labor next-business-day warranty standard. Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems. DS Implementation Guide TD Back to Top Step 5: Please see below for warranty uplift options. Without storage partitioning, the logical drives configured on a DS can only be accessed by a limited number of host systems or by a fs3400 cluster.

Back to Top Step 2: DS Sample Configurations 2. Holds up to drives internally and connection for up to 3 EXP’s.

We call these sets storage partitions. EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3. Therefore, the access to that LUN is exclusively reserved for that host. It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. DS comes standard with 4 storage partitions. Premium Features Step 6: DS upgrade from 4 to 16 storage partitions.

DS Model Step 2: That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server. This can surely lead to inefficient use of Storage Server hardware. VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive.

DS upgrade from 4 to 32 storage partitions. Back to Top Step 4: 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.


DS upgrade from 8 to 32 storage partitions. DS upgrade from 8 to 16 storage partitions. Back to Top Step 3: The VolumeCopy premium feature allows for up to VolumeCopies. The DS is a direct-attach and SAN solution for System x, and BladeCenter servers, and enables small and medium businesses to manage their fast-growing data capacity requirements on an affordable budget.

Allows for up to 4 FlashCopies per volume.

FlashCopy is a point-in-time copy of a source logical drive. Ships with the rack mounting kit and two 2.

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