HP StorageWorks 4000/6000/8000 - Enterprise Virtual Arrays - XP Continuous Access Protocols and Source-Target Replication Pairing

XP Continuous Access is supported using the Fibre Channel protocol or ESCON protocol. Current 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 166 describes the supported protocol and storage system source-target combinations.

Legend: • = supported; — = not supported
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 XP storage systems. (See Table
165 for firmware versions.)

Access Synchronous replication.
