HP P6000 Continuous Access Implementation Guide (T3680-96431, August 2012)

1 HP P6000 Continuous Access
HP P6000 Continuous Access is the remote replication component of HP controller software. When
this component is licensed and configured, the controller copies data online, in real time, to a
remote array over a SAN. Properly configured, HP P6000 Continuous Access provides a
disaster-tolerant storage solution that ensures data integrity and, optionally, data currency RPO if
an array or site fails.
Figure 1 (page 7) shows a typical remote replication setup with arrays on local and remote sites
connected by two linked fabrics. Two ISLs connect the local and remote fabrics.
NOTE: In SAN design terminology, an ISL is also referred to as an interswitch link.

Features
HP P6000 Continuous Access features include:
• Continuous replication of local virtual disks on remote virtual disks
• Synchronous, basic asynchronous, and enhanced asynchronous replication modes
• Automated failover when used with other cluster software
• Failsafe data protection
• Ability to suspend and resume replication
• Bidirectional replication
• Graphical and command line user interfaces (GUI and CLUI) to simplify replication management
• Automatic suspension of replication if the link between arrays is down.
