Purchase two for dual controller models.

Now the host systems can only access their assigned logical drives, just as if these logical drives were locally attached to them. Without storage partitioning, the logical drives configured on a DS can datashfet be accessed by a limited number of host systems or by a single cluster.

DS upgrade from 8 to 32 storage partitions. DS Implementation Guide Allows for up to 4 FlashCopies per volume.

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. The time required to establish a copy will depend on the size of the source data and the operation priority settings. DS comes standard with 4 storage partitions.

Many options are available to uplift this protection to higher levels. Ships with the rack mounting kit and two 2. With FC host connectivity and SAS back-end de3400, the DS is designed to improve productivity inm data consolidation, availability, performance and scalability.

Therefore, the access to that LUN is dx3400 reserved for that host. The EXP comes with a 3 year, parts and labor next-business-day warranty standard. DS upgrade from 8 to 16 storage partitions. Back to Top Step 3: You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive. Once all the data is copied to the target, the target will remain available if the source logical drive is lost. Back to Top Step 9: Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives.

The VolumeCopy premium feature allows for up to VolumeCopies.

SAN Switches Step 8: Back to Top Step 2: Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems.

DS Sample Datashwet 2. 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 16 to 32 storage partitions. Holds up to drives internally and connection for up to 3 EXP’s. We call these sets storage partitions. Expansion Unit Step 3: Please see below for warranty uplift options.

Back to Top Step 4: DS Model Step 2: Two SFP’s needed for the single controller model. Storage partitioning adds a high level of flexibility to the DS Storage Server.

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.

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. Be aware that FlashCopy is a prerequisite for VolumeCopy. TD Back to Top Step 5: 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.

As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies. Premium Features Step 6: The DS comes with a 3 year, parts and labor next-business-day warranty standard. VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. Walk through this step-by-step guide, choosing appropriate models and options as indicated below: DS upgrade from 4 to 32 storage partitions.

The DS is a direct-attach and SAN solution for System x, and BladeCenter servers, and enables small and medium businesses ds340 manage their fast-growing data capacity requirements on an affordable budget. While establishing the copy, the source logical drive will be in read-only state.

This can surely lead to inefficient use of Storage Server hardware. Four SFP’s needed for dual controller model. That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server. It allows you to connect a much higher number of host systems, either in stand-alone or clustered dxtasheet. DS upgrade from 4 to 16 storage partitions.
