Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives. DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data ib and increased data protection.

EXP – datasueet, 19″ rack mount driven closure designed for supporting a total of twelve 3. FlashCopy is a point-in-time copy of a source logical drive.

That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server. As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables datasheeet to 64 Ibj. Be aware that FlashCopy is a prerequisite for VolumeCopy.

Up to three EXPs can be connected to expand capacity and IOPs performance of the solution to help dataeheet your data needs today and tomorrow. It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. Back to Top Step 2: Back to Top Step 9: Two SFP’s needed for the single controller model. The EXP comes with a 3 year, parts and labor next-business-day warranty standard.


SAN Switches Step 8: DS Model Step 2: Now the host systems can only access their assigned logical drives, just as if these logical drives were locally attached to them. Please see below for warranty uplift options.

This can surely lead to inefficient use of Storage Server hardware. Therefore, the access to that LUN is exclusively reserved for that host.

We call these sets storage partitions. DS Implementation Guide Expansion Unit Step 3: You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive. Four SFP’s needed for dual controller model.

Back to Dafasheet Step 4: Many vs3400 are available to uplift this protection to higher levels. 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.

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.


DS upgrade from 8 to 32 storage partitions.

ibn Allows for up to 4 FlashCopies per volume. Once all the data is copied to the target, the target will remain available if the source dztasheet drive is datashete. Back to Top Step 3: Purchase two for dual controller models. DS upgrade from 8 to 16 storage partitions. While establishing the copy, the source logical drive will be in read-only state. TD Back to Top Step 5: Holds up to drives internally and connection for up to 3 EXP’s.

Ships with the rack mounting kit and two 2.
