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.

Ships with the rack mounting kit and two 2. Allows for up to 4 FlashCopies per volume. Storage partitioning adds a high level of flexibility to the DS Storage Server. Please see below for warranty uplift options.

VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. Four SFP’s needed for dual controller model.

Datasheef FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent 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. Be aware that FlashCopy is a prerequisite for VolumeCopy.

Two SFP’s needed for the single controller model. Storage partitioning adapts the SAN idea of globally accessible storage to the dqtasheet operating systems.

This can surely lead to inefficient use of Storage Server hardware. That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server.

The time required to establish a copy will depend on the size of the source data and the operation priority settings. Back to Datwsheet Step 4: 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.

Once all the data is copied to the target, the target will remain available if the source logical drive is lost. 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.


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. Walk through this step-by-step guide, choosing appropriate models and options adtasheet indicated below: DS Sample Configurations 2. FlashCopy is a point-in-time copy of a source logical drive.

DS comes standard with 4 storage partitions. EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3.

While establishing the copy, the source logical drive will be in read-only state. DS upgrade from 8 to 32 storage partitions. Holds up to drives internally and connection for up to 3 EXP’s. Without storage partitioning, the logical drives configured on a DS can only be accessed by a limited number of host systems or by a d3400 cluster.
