IBM System Storage DS3400

With FC host connectivity and SAS back-end technology, the DS is designed to improve productivity through data consolidation, availability, performance and scalability. DS Sample Configurations 2. DS Implementation Guide Walk through this step-by-step guide, choosing appropriate models and options as indicated below: 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.

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. Holds up to drives internally and connection for up to 3 EXP’s. Two SFP’s needed for the single controller model. Ships with the rack mounting kit and two 2.

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. The EXP comes with a 3 year, parts and labor next-business-day warranty standard. Please see below for warranty uplift options.

FlashCopy is a point-in-time copy of a source logical drive. Allows for up to 4 FlashCopies per volume. As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies.

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. You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive. The time required to establish a copy will depend on the size of the source data and the operation priority settings. While establishing the copy, the source logical drive will be in read-only state.

Once all the data is copied to the target, the target will remain available if the source logical drive is lost. The VolumeCopy premium feature allows for up to VolumeCopies.

Be aware that FlashCopy is a prerequisite for VolumeCopy. It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. 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. This can surely lead to inefficient use of Storage Server hardware. Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives.

We call these sets storage partitions. Now the host systems can only access their assigned logical drives, just as if these logical drives were locally attached to them.

Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems. That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server.

Therefore, the access to that LUN is exclusively reserved for that host. DS comes standard with 4 storage partitions. Back to Top Step 9: Four SFP’s needed for dual controller model. EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3.

DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data backups and increased data protection.

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.
