Two SFP’s needed for the single controller model. The EXP comes with a 3 year, parts and labor next-business-day warranty standard. Storage partitioning adds a high level of flexibility to the DS Storage Server. As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies. With FC host connectivity and SAS back-end technology, the DS is designed datsheet improve productivity through datashret consolidation, availability, performance and scalability.
SAN Switches Step 8: DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data backups and increased data protection. DS upgrade from 4 to 32 storage partitions. Ibj, the access to that LUN is exclusively reserved for that host.
That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server. This can surely lead to inefficient use of Storage Server hardware. Back to Top Step 9: TD Back to Top Step 5: The DS comes with a 3 year, parts and labor next-business-day warranty standard. Many options are available to uplift this protection to higher levels.
Now the host systems can only access their datasheft logical drives, just as if these logical drives were ds34000 attached to them. Ships with the rack mounting kit and two 2.

Please see below for warranty uplift options. The VolumeCopy premium feature allows for up to VolumeCopies. DS upgrade from 16 to 32 storage partitions. It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode.
Allows for up to 4 FlashCopies per volume.

Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems. DS upgrade from 8 to 32 storage partitions.
Purchase two for dual controller models. DS Model Step 2: DS Sample Configurations 2.
We call these sets storage partitions. Four SFP’s needed for dual controller model.

VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. DS Implementation Guide Holds up to drives internally and connection for up to 3 EXP’s. You can use this functionality for data replication, relocation, backup, or to restore snapshot datqsheet to the original logical drive. The time required to establish a copy will depend on the size of the source data and the datasbeet priority settings.
Back to Top Step 3: Once all the data is copied to the target, the target will remain available if the source logical drive is lost. The DS is a dagasheet 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.

Expansion Unit Step 3: DS upgrade from 8 to 16 d3s400 partitions. Be aware that FlashCopy is a prerequisite for VolumeCopy. DS comes standard with 4 storage partitions.
DS upgrade from 4 to 16 storage partitions.
Premium Features Step 6: While establishing the copy, the source logical drive will vatasheet in read-only state. Walk through this step-by-step guide, choosing appropriate models and options as indicated below: 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.
FlashCopy is a point-in-time copy of a source logical drive. EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3. 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.
Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives. Back to Top Step 4: As opposed to FlashCopy where only the original values of changed data are copied to the datahseetthe whole source logical ib is copied to target. Back to Top Step 2:
