Holds up to drives internally ds3040 connection for up to 3 EXP’s. Ships with the rack mounting kit and two 2. The DS is a direct-attach and SAN solution for System x, and BladeCenter servers, and enables datasheeet and medium iibm to manage their fast-growing data capacity requirements on an affordable budget. Therefore, the access to that LUN is exclusively reserved for that host.
You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive. SAN Switches Step 8: Two SFP’s needed for the single controller model. VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. DS comes standard with 4 storage partitions. As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies.
DS Model Step 2: The EXP comes with a 3 year, parts and labor next-business-day warranty standard. Walk through this step-by-step guide, choosing appropriate models and options as indicated below: EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3.
DS upgrade from 8 to 32 storage partitions. That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server. DS upgrade from 16 to 32 storage partitions. Four SFP’s needed for dual controller model. Many options are available to uplift this protection to higher levels.
DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data backups and increased data protection.

Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives. Back to Top Datassheet 2: Storage partitioning adds a high level of flexibility to the DS Storage Server.
While establishing the copy, the source logical drive will be in read-only state. Without storage partitioning, the logical drives configured on a DS can only be accessed by a limited number of host systems or by a single cluster.
Expansion Unit Step 3: Back to Top Step 4: Allows for up to 4 FlashCopies per volume.
Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems. With FC host connectivity and SAS back-end technology, the DS is designed to improve productivity through data consolidation, availability, performance and scalability. DS upgrade from 8 to 16 storage partitions.
Back to Top Step 9: DS Implementation Guide 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 4 to 32 storage partitions. The DS comes with a 3 year, parts and labor next-business-day warranty standard. Purchase two for dual controller models.
IBM System Storage DS Overview – IBM System Storage – India
The VolumeCopy premium feature allows for up to VolumeCopies. Once all the data is copied to the target, the target will remain available if the source logical drive is lost.
Now the host systems can only access their assigned logical drives, just ivm if these logical drives were locally attached to them. Available in 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 upgrade from 4 to 16 storage partitions.

It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. DS Sample Configurations 2. We call these sets storage partitions. This can surely lead to inefficient use of Storage Server hardware.
Back to Top Step 3: Up to three EXPs can be connected to expand capacity and IOPs performance of the solution to help address your data needs today and tomorrow. Premium Features Dztasheet 6: FlashCopy is a point-in-time copy of a source logical drive.
The time required to establish a copy will depend on the size of the source data and the operation priority settings.
