Allows for up to 4 FlashCopies per volume. 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.
Storage partitioning adds a high level of flexibility to the DS Storage Server. DS Model Step 2: Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives.
EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve datasheeet.
Datadheet upgrade from 4 to 32 storage partitions. Please see below for warranty uplift options. Back to Top Step 4: The VolumeCopy premium feature allows for up to VolumeCopies. 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.
This can surely lead to inefficient use of Storage Server hardware. Premium Features Step 6: As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies.

Walk through this step-by-step guide, choosing appropriate models and options as indicated below: You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive. Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems.
FlashCopy is a point-in-time copy of a source logical drive. Therefore, the access to that LUN is exclusively reserved for that host. DS upgrade from 4 to 16 storage partitions. With FC host connectivity and SAS back-end technology, the DS is designed to improve productivity through data consolidation, availability, performance and scalability. DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data backups and increased data protection.
The Igm comes with a 3 year, parts and labor next-business-day warranty standard. Ships with the rack mounting kit and two 2. Bim Implementation Guide Many options are available to uplift this protection to higher levels.
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 comes standard with 4 storage partitions. TD Back to Top Step 5: Be aware that FlashCopy is a prerequisite for VolumeCopy. The time required to establish a copy will depend on the size of the source data and the operation priority settings. 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.
Purchase two for dual controller models.

DS Sample Configurations 2. Four SFP’s needed for dual controller model. It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. The DS eatasheet with a 3 year, parts and labor next-business-day warranty standard. 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. 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. Now the host systems can only access their assigned logical dataxheet, just as if these logical drives were locally attached to them.
DS upgrade from 8 to 32 storage partitions. Holds up to drives internally and connection for up to 3 EXP’s. Datashete upgrade from 8 to 16 storage partitions.
While establishing the copy, the source logical drive will be in read-only state. SAN Switches Step 8: Back to Top Step 9: DS upgrade from 16 to 32 storage partitions. Once all the data datashret copied to the target, the target will remain available if the source logical drive is lost.
