Hitachi Virtual LVI Converts single volumes (logical volume images or logical units) into multiple
smaller volumes to improve data access performance.
Hitachi Data Retention
Utility Protects data in logical units / volumes / LDEVs from I/O operations illegally
performed by host systems. Users can assign an access attribute to each
volume to restrict read and/or write operations, preventing unauthorized
access to data.
Feature Description
Hitachi Virtual LVI Converts single volumes (logical volume images or logical units) into multiple
smaller volumes to improve data access performance.
Hitachi Volume Security
software Restricts host access to data on the Virtual Storage Platform. Open-system
users can restrict host access to LUNs based on the host's world wide name
(WWN). Mainframe users can restrict host access to volumes based on node
IDs and logical partition (LPAR) numbers.
Hitachi Volume
Retention Manager Protects data from I/O operations performed by hosts. Users can assign an
access attribute to each logical volume to restrict read and/or write
operations, preventing unauthorized access to data.
Feature Description
Hitachi TrueCopy® Remote
Replication software and
Hitachi TrueCopy®
Synchronous software for
Mainframe Performs remote copy operations between storage systems at different
locations. TrueCopy provides the synchronous copy mode for open
systems. TrueCopy for Mainframe provides synchronous copy for
mainframe systems.
Hitachi ShadowImage® In-
System Replication software
and
Hitachi ShadowImage® In-
System Replication software
for Mainframe Creates internal copies of volumes for purposes such as application
testing and offline backup. Can be used in conjunction with True Copy or
Universal Replicator to maintain multiple copies of data at primary and
secondary sites.
Hitachi Copy-on-Write
Snapshot software and
Hitachi Thin Image (open
systems only) Snapshot creates a virtual, point-in-time copy of a data volume. Since
only changed data blocks are stored in the Snapshot storage pool,
storage capacity is substantially less than the source volume. This
results in significant savings compared with full cloning methods. With
Copy-on-Write Snapshot, you create virtual copies of a data volume in
the Virtual Storage Platform. Thin Image can perform the cost-effective
duplication by storing only differential data between primary volumes
and secondary volumes of VVOLs.
Hitachi Universal Replicator
software and
Hitachi Universal Replicator
software for Mainframe
This feature provides a RAID storage-based hardware solution for
disaster recovery which enables fast and accurate system recovery,
particularly for large amounts of data which span multiple volumes.
Using Universal Replicator, you can configure and manage highly reliable
data replication systems using journal volumes to reduce chances of
suspension of copy operations.
Compatible FlashCopy® V2 This feature provides compatibility with IBM Extended Remote Copy
(XRC) asynchronous remote copy operations for data backup and
recovery in the event of a disaster.
