5 Using Dell PS Series Asynchronous Replication | TR1052
Introduction
Replication provides a method for protecting volume data without setting the volumes offline and without
causing disruption to applications and users. It also provides a disaster-recovery option in case the original
group or volume is destroyed or unavailable.
Dell™ PS Series Asynchronous Replication is used to copy volume data from one PS Series group to
another PS Series group. The two groups must be connected through a TCP/IP network, and can be an
unlimited distance apart.
Audience
The information in this guide is intended for technology professionals interested in using Dell PS Series
storage with Asynchronous Replication to protect and recover data.
Objective
This guide details the Asynchronous Replication feature in Dell PS Series firmware.
While Dell PS Series storage also provides real-time data protection with Synchronous Replication, this
topic is not covered in this guide. For additional information on Synchronous Replication, refer to the
document, Dell EqualLogic PS Series Array: Understanding Synchronous Replication (SyncRep) .
For off-network PS Series volume replication, Dell also provides a standalone program called the Manual
Transfer Utility. For additional information on this program, refer to the Manual Transfer Utility Version
