Back to Top Step 9: The time required to establish a copy will depend on the size of the source data and the operation priority settings. Ships with the rack mounting dz3400 and two 2. Allows for up to 4 FlashCopies per volume.
The DS comes with a 3 year, parts and labor next-business-day warranty standard. 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.
Please see below for warranty uplift options. DS upgrade from 4 to 32 storage partitions. The EXP datasjeet with a 3 year, parts and labor next-business-day warranty standard. DS upgrade from 16 to 32 storage partitions. Available in single and dual controller models, the DS scales in capacity to support a total dx3400 48 hard disk drives by using the EXP expansion unit. DS upgrade from 4 to 16 storage partitions. Holds up to drives internally and connection for up to 3 EXP’s.
DS upgrade from 8 to 16 storage partitions. The DS is a direct-attach and SAN solution for System x, and BladeCenter servers, and datasjeet small and medium businesses to manage their fast-growing data capacity requirements on an affordable budget.

DS Sample Configurations 2. The VolumeCopy premium feature allows for up to VolumeCopies. Walk through this step-by-step guide, choosing appropriate models and options as indicated below: 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. With FC host connectivity and SAS back-end technology, the DS is designed to improve productivity through data consolidation, availability, performance and scalability.
Two SFP’s needed for the datashee controller model. SAN Switches Step 8: Storage partitioning adds a high level of flexibility to the DS Storage Server. DS comes standard with 4 storage partitions. Purchase two for dual controller models. EXP – 2U, 19″ rack mount driven closure designed for supporting a total of twelve 3.
DS Model Step 2: Storage partitioning adapts the SAN idea of globally accessible storage to the local-storage-minded operating systems. Back to Top Step 2: Four SFP’s needed for dual controller model. DS Implementation Guide Back to Top Step 4: TD Back to Top Step 5: As a standard configuration, 2 FlashCopies are enabled on every DS storage subsystem and this premium feature enables up to 64 FlashCopies.
Expansion Unit Step 3: Premium Features Step 6: As opposed to FlashCopy datashee only the original values of changed data are copied to the repositorythe whole source logical drive is copied to target.
Be datasheeet that FlashCopy is a prerequisite for VolumeCopy. Storage partitioning, on the other hand, allows you to create sets, containing the hosts with their host bus adapters and the logical drives. FlashCopy is a point-in-time copy of a source logical drive. Now the host systems can only access their assigned logical drives, just as if these logical drives were locally attached to them.
datsaheet Back to Top Step 3: We call these sets storage partitions. You can use this functionality for data replication, relocation, backup, or to restore snapshot data to the original logical drive.
IBM System Storage DS3400 Express Data Sheet
It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. Many dataaheet are available to uplift this protection to higher levels. Therefore, the access to that LUN is exclusively reserved for that host. DS FlashCopy Expansion Plus License increases the number of FlashCopies per volume to eight allows more frequent data backups and increased data protection.
Once all the data is copied to the target, the target will remain available if the source logical drive is lost. This can surely lead to inefficient use of Storage Server hardware. That means once you have assigned the LUN to a host rs3400 is hidden from all other hosts connected to the same Storage Server.
VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. While establishing the copy, the source logical drive will be in read-only state. DS upgrade from 8 to 32 storage partitions.
