flexibility and availability. The logical paths between the MCU and RCU must be separate from the
logical paths between the host and RCU. For serial interface connections, all remote copy activities
between two XP128/XP1024/XP10000/XP12000s, such as TC390, TC390A, CA Sync, and CA
Async, can share the same remote copy connections. For Fibre Channel interface connections, only
TC390 activities (Sync and Async) can share the same fibre remote copy connections (future support
will eliminate this restriction). For information on using channel extenders, see ”

Fibre Remote Copy Connections
The following figure shows the remote copy connection configurations for Fibre Channel interface TC390
operations. The MCU and RCU of each TC390 pair must be connected through multimode shortwave or
single-mode longwave optical fibre cables. If you use multimode shortwave optical fibre cables, fibre
cables up to 1.5 km in length and up to two switches are required for distances greater than 0.5 km. If you
use single-mode longwave optical fibre cables, fibre cables up to 30 km in length and up to two switches
are required for distances greater than 10 km. TC390 operations can be performed at distances of up to
30 km (18.6 miles) using standard single-mode longwave support. Long-distance solutions are provided
using approved channel extenders and communication lines.

NOTE:
For Fibre Channel interface connections, you can use the switches as for ordinary switch
connections and no special settings are required for the XP128/XP1024/XP10000/XP12000.
Fibre Channel interface connection provides three different configurations:
•
Direct connection: Two devices are connected directly together.
