The remote replication feature for PowerVault MD3 storage systems efficiently replicates data between locations to make sure that information is protected from both system failures and site failures. This feature duplicates data between PowerVault MD3 storage systems to make sure data is available in the event of a disaster and for other business data migration needs. This document describes how the remote replication feature provides recovery points and group-oriented consistency across multiple virtual disks and supports efficient data transfers over FC and iSCSI (TCP/IP) networks.
