6 Data replication operations with RAID Manager
This chapter describes data replication operations with RAID Manager.
About data replication operations
The data replication features of the RAID storage system include:
•
Local replication:
Business Copy ◦
◦ Snapshot
◦ Auto LUN
•
Remote replication:
Continuous Access Synchronous ◦
◦ Continuous Access Asynchronous
◦ Continuous Access Journal
For detailed information about any of these features, see the applicable user guide (for example,
HP XP7 Business Copy User Guide).
Features of paired volumes
Paired logical volumes are often handled independently by servers. When RAID Manager is used,
the paired volumes can be managed by the Continuous Access Synchronous, Business Copy,
and/or Continuous Access Journal pairing functions, as combined or separated pairs. Continuous
Access Synchronous, Business Copy, and Continuous Access Journal regard the two volumes being
combined or separated as a uniquely paired logical volume used by the servers. Paired volumes
can also be handled as groups, grouping them by units of server software or units of databases
and their attributes.
For detailed information about volume pairs (for example, maximum number of pairs per storage
system, maximum P-VOL size), see the user guide for your storage system and copy function (for
example, HP XP7 Business Copy User Guide).
