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. Be aware dqtasheet FlashCopy is a prerequisite for VolumeCopy. Once all the data is copied to the target, the target catasheet remain available if the source logical drive is lost. 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.

Back to Top Step 9: 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. DS upgrade from 8 to 16 storage partitions.

Allows for up to 4 FlashCopies per volume. DS Model Step 2: The time required to establish a copy will depend on the size of the source data and the operation priority settings.

DS Sample Configurations 2. Dtasheet FC host connectivity and SAS back-end technology, the DS is designed to improve productivity through data consolidation, availability, performance and scalability. FlashCopy is a point-in-time copy of a source logical drive.

DS upgrade from 4 to 16 storage partitions. 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. We call these sets storage partitions.

Holds up to drives internally and connection for up to 3 EXP’s. Storage partitioning, on the other hand, allows you to create sets, containing the datasueet with their host bus adapters and the logical drives. ibn

Back to Top Step 4: The VolumeCopy premium feature allows for up to VolumeCopies. The DS comes with a 3 year, parts and labor next-business-day warranty standard.

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.

This can surely lead to inefficient use of Storage Server hardware. DS upgrade from 8 to 32 storage partitions. DS upgrade from 4 to 32 storage partitions. Four SFP’s needed for dual controller model. Datxsheet allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. VolumeCopy ibbm a way to provide a complete point-in-time copy of a source logical drive. Premium Features Step 6: DS comes standard with 4 storage partitions.

Purchase two for dual controller models. As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies.


That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server. Please see below for warranty uplift options.


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

SAN Switches Step 8: While establishing the copy, the source logical drive will be in read-only state.

Walk through this step-by-step guide, choosing appropriate models and options as indicated below: TD Back to Top Step 5: EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3.

Storage partitioning adds a high level of satasheet to the DS Storage Server. Now the host systems can only access their assigned logical drives, just as if these logical drives were locally attached to them. Back to Top Step 2: Ships with the rack mounting kit and two 2.

The EXP comes with a 3 year, parts and labor datashete warranty standard. You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive.

Back to Top Step 3: Two SFP’s needed for the single controller model. DS upgrade from 16 to 32 storage partitions. Expansion Unit Step 3: DS Implementation Guide Storage partitioning adapts the SAN datasjeet of globally accessible storage to the local-storage-minded operating systems.
