5.6.4
LUN Expansion Function
The LUN Expansion function expands the size of a logical unit (volume) accessed by a host
computer by combining multiple logical units (volumes) internally.
5.6.5
Password Protection Function
The Password Protection function restricts the number of Storage Navigator Modular users
who are allowed to access a disk array subsystem; it also prevents simultaneous access from
multiple users.
5.7
Copy Solution Features and Functions
The AMS200 subsystem provides features and functions which allow you to maintain remote
and subsystem internal copies of all user data on the AMS200 storage subsystem for data
backup or duplication. These features include:
ShadowImage In-System Replication Function
Copy-On-Write Snapshot Function
NAS Backup Restore Modular Function
NAS SyncImage Modular Function
5.7.1
ShadowImage In-System Replication Function
The Hitachi Data Systems ShadowImage In-System Replication function enables you to
maintain subsystem-internal copies of all user data on the AMS200 storage subsystem for
purposes such as data backup or duplication. The duplicated volumes are created within the
same AMS200 subsystem as the primary volume.
ShadowImage In-System Replication operations are non-disruptive and allow the primary
(main) volume of each volume pair to remain online to all hosts for both read and write I/O
operations. Once established, ShadowImage In-System Replication operations continue
unattended to provide asynchronous internal data backup. Usability is further enhanced
through a resynchronization capability that reduces data duplication requirements and
backup time, thereby increasing user productivity.
5.7.2
Copy-On-Write Snapshot Function
The Hitachi Copy-On-Write Snapshot feature enables you to maintain a logical copy of logical
units (volumes) at a point in time between the disk array subsystems.
