HP XP7 Documentation Roadmap (H6F56-96004)

Synchronous. By combining data-copy program products features, you can recover important data
from all kinds of failures.
For example, by using Continuous Access Journal and Continuous Access Synchronous, you can
manage copied volumes in a 3-data-center configuration. If a failure occurs in one of the data
centers during business hours, volumes in another data center can be used to continue the business.
Volume replication can then be performed in the third data center.
HP XP7 for Compatible XRC User Guide
Compatible Replication for IBM XRC provides asynchronous remote replication functions for data
backup in the event of a disaster.
With Compatible XRC, the data written from the host at the primary site is written to the primary
volume by means of the cache memory at the primary storage system. At the same time, the data
is temporarily stored in cache memory as a sidefile. At the secondary site, the System Data Mover
(SDM) software asynchronously reads the sidefile data over communications lines from the primary
storage system at the primary site. SDM then writes the data to the secondary volume in the
secondary storage system in the same order as it was written at the primary site.
Compatible XRC is used for mainframe systems and is compatible with Extended Remote Copy,
which is an IBM host software feature.
Compatible XRC is compatible with System Data Mover in Data Facility Storage Management
Subsystem (DFSMS), which is common to the XRC environment.
HP XP7 Auto LUN User Guide
Auto LUN provides functions tor migrate volumes to optimize and balance workloads on data
drives.
If an excessive number of accesses to particular data drives or data are made from hosts , the I/O
wait time for the data drives increases, and the performance might decrease. Auto LUN allows
you to balance access workloads that are concentrated on particular data drives, removing
bottlenecks from your system.
Migrating volumes using Auto LUN is completely non-disruptive because the data being migrated
can remain online to all hosts for read and write operations throughout the entire migration process.
When the load to a specific processor increases, loads can be dispersed due to migrating volumes
by Auto LUN.
FICON® Data Migration Operation Manual
FICON® Data Migration migrates data from an existing storage system to a new storage system
by using the FICON® interface.
In general, data migration is invoked by a mainframe host or a storage system. If FICON® Data
Migration is used, data migration is invoked by a storage system and is not affected by the
performance of hosts.
To perform data migration, use this function in conjunction with Business Copy Z.
HP XP7 SNMP Agent User Guide
SNMP Agent
SNMP Agent collects information such as network device errors and network device usage, using
the SNMP network management protocol. The SNMP Agent is installed on a disk or other device
that are managed on the network. When a failure occurs, the SNMP Agent issues an SNMP trap
to SNMP Manager to report the failure. In addition, SNMP Agent can report product numbers,
nicknames, reference codes, and component identifiers.
