Adding Existing Hitachi Data Protection Capabilities to HUS
Additional block‐based replication software packages that are also supported on the HUS platform
include:
Hitachi Replication Manager (HRpM)—a module within Hitachi Command Suite that allows the HUS
administrator to aggregate the set‐up, configuration, and on‐going management of multiple block‐based
copy functions supported for use with HUS. This applies to local and remote HUS systems.
Administrators can schedule and automate replication processes using HRpM.
Hitachi Data Protection Suite (HDPS) — based on CommVault Simpana.
Hitachi TrueCopy Synchronous and TrueCopy Extended Distance —for remote copying of full volume
data clones, TrueCopy Synchronous supports synchronous data replication and immediate recoverability
when using a target HDS storage platform located up to 300km away. TrueCopy Extended Distance
utilizes asynchronous replication for volume cloning over any distance for disaster recovery and business
continuance purposes.
Conclusion
HUS represents an advancement in storage system‐based data protection in that both the block and file
sides of a unified storage system are included under the unified storage umbrella. For block storage,
administrators can use Hitachi Copy‐on‐Write Snapshot and ShadowImage. For file and object storage,
JetClone is offered. Both support in‐system backup and recovery processes. HAPRO combines these
capabilities for both block and file data protection under a unified storage umbrella that is managed
from a familiar interface.
In addition, both HAPRO and Dynamic Replicator give storage administrators the ability to implement
application‐level data protection in ways that can be managed by other IT staff members including
application administrators. This takes a set of time consuming and repetitive tasks, and delegates them
to other IT stakeholders.
As noted earlier, accelerating demand for storage capacity across industry segments is gradually
rendering existing data protection practices ineffective and unsustainable. In‐system data protection
relieves the pressure on existing data center‐based backup and recovery processes so they can be
continually scaled upward to cover explosive data growth. Application‐level data protection that is also
implemented within the storage system allows storage administrators to simplify their working
environments. Hitachi delivers both these capabilities within the HUS framework.
