Replication between XP24000/20000 and XP12000/10000 requires firmware 50.09.37.00/02 (or later).
HP P9000 (XP) Continuous Access is supported using the Fibre Channel protocol or ESCON
protocol. Current P9500 and XP storage systems support replication using Fibre Channel. Legacy
XP storage systems use either Fibre Channel or ESCON. Data replication between different storage
systems is supported only if they use the same protocol.
Table 155 (page 305) describes the supported protocol and storage system source-target
combinations.

When performing replication between two storage systems, the following restrictions apply:
• Legacy storage systems have limitations on the control-unit range, port numbers, and LUNs.
• Support for “host group” is limited by storage system functionality. This also affects the internal
addressing of devices allocated to host ports and the configuration of RAID Manager.
• The emulation mode and the device (volume) size must be the same on both storage systems.
• There are firmware requirements for replication between different P9500 and XP storage
systems. For firmware versions, see Table 154 (page 305).

Synchronous replication is supported on P9500, XP24000/20000, and XP12000/10000 storage
systems. The maximum distance or latency supported for synchronous replication is 200 km when using
