Many options are available to uplift this protection to higher levels. That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server.

We call these sets storage partitions. Be aware that FlashCopy is a prerequisite for VolumeCopy. SAN Switches Step 8: Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives. DS upgrade from 16 to 32 storage partitions. DS upgrade from 4 to 16 storage partitions. 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 Step 6: While establishing the copy, the source logical drive will be in read-only state.

IBM System Storage DS Overview – IBM System Storage – India

Allows for up to 4 FlashCopies per volume. Now the host systems can only access their assigned logical drives, just datasneet if these logical drives were locally attached to them. 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.

Four SFP’s datasheet for dual controller model. TD Back to Top Step 5: DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data backups and increased data protection.

As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies.

EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3. Storage partitioning adapts the SAN idea of globally accessible storage ibmm the local-storage-minded operating systems.

The time required to establish a copy will depend on the size of the source data and the operation priority settings.

Once all the data is copied to the target, the target will remain available if the source logical drive is lost.

Back to Top Step 3: Back to Top Step 4: 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. FlashCopy is a point-in-time copy of a source logical drive. 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. The EXP comes with a 3 year, parts and labor next-business-day warranty standard.

This can surely lead to inefficient use of Storage Server hardware. Expansion Unit Step 3: Ships with the rack mounting kit and two datqsheet. DS comes standard with 4 storage partitions. DS Sample Configurations 2. Storage partitioning adds a high level of flexibility to the DS Storage Server.

VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. With FC host connectivity and SAS back-end technology, dw3400 DS is designed to improve productivity through data consolidation, availability, performance and scalability.

Two SFP’s needed for the single controller model. The VolumeCopy premium feature allows for up to VolumeCopies. Walk through this step-by-step guide, choosing appropriate models and options as indicated below: DS upgrade from 8 to 16 storage partitions.

It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode.
