HP Application Recovery Manager software A.06.10 Concepts guide (March 2008)

Local replication
For local replication, the HP StorageWorks Business Copy (BC) EVA configuration is
used. This enables you to create replicas to be used for instant recovery purposes
(note that only snapclones can be used for instant recovery). With this, large replica
sets can be used, the number of members being limited primarily by the available
space on the array. The maximum number of standard snapshots and vsnaps is
limited by the EVA storage system.
Local replication integrating with LVM mirroring
The Application Recovery Manager EVA integration supports LVM mirroring in
configurations where volume groups are LVM-mirrored from one (or more) EVA(s) to
another EVA(s). The LVM-mirrored source volumes and their LVM mirrors belong to
the same logical volume.
For this configuration, you need at least two disk arrays located in physically separate
sites.
