Back to Top Step 9: Purchase two for dual controller models. 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. Four SFP’s needed for dual controller model. DS Model Step 2: EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3.

Premium Features Step 6: Back to Top Step 3: We call these sets storage partitions. DS upgrade from 4 to 32 storage partitions.

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

Ships with the rack mounting kit and two 2. Holds up to drives internally and connection for up to 3 EXP’s. Allows for up datasheey 4 FlashCopies per volume. This can surely lead to inefficient use of Storage Server hardware.

DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more datashwet 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.


DS upgrade from 8 to 16 storage partitions. Back to Top Step 4: Back to Top Step 2: FlashCopy is a point-in-time copy of a source logical drive. With FC host connectivity and SAS back-end technology, datashet DS is designed to improve productivity through data consolidation, availability, performance and scalability.

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 datasheeg an affordable budget.

Be aware that FlashCopy is a prerequisite for VolumeCopy. DS comes standard with 4 storage partitions. The EXP comes with a 3 year, parts and labor next-business-day warranty standard. Expansion Unit Step 3: Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems. The DS comes with a 3 year, parts and labor next-business-day warranty standard.

Therefore, the access to dw3400 LUN is exclusively reserved for that host.

Many options are available to uplift this protection to higher levels. DS upgrade from 16 to 32 storage partitions.

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. The time required to establish a copy will depend on the size of the source data and the operation priority settings. The VolumeCopy premium datashheet allows for up datadheet VolumeCopies.

That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server.

VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. Two SFP’s needed for the single controller model. You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive. DS Implementation Guide SAN Switches Step 8: Walk through this step-by-step guide, choosing appropriate models and options as indicated below: DS upgrade from 4 to 16 storage partitions.

DS upgrade from 8 to 32 storage partitions. Once all the data is copied to the target, the target will remain available if the source logical drive is lost. Please see below for warranty uplift options. Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives. TD Back to Top Step 5: DS Sample Configurations 2. Now the host systems can only access their assigned logical drives, just as if these logical drives were locally attached to them.

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. Storage partitioning adds a high level of flexibility to the DS Storage Server.
