Setting up Remote Copy Connections
The following figure shows the remote copy connection configurations for Universal Replicator for
Mainframe operations. The primary storage system and secondary storage system of each Universal
Replicator for Mainframe pair must be connected via optical fiber cables. If you use multimode
shortwave optical fiber 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 long wave optical fiber cables,
fibre cables up to 30 km in length and up to two switches are required for distances greater than
10 km. Universal Replicator for Mainframe operations can be performed at distances of up to 30
km (18.6 miles) using standard single-mode long wave support. For further distance, the channel
extender connections are required. Universal Replicator for Mainframe operations can be performed
at distances of up to 30 km (18.6 miles) using standard single-mode long wave support. For
distances greater than 43 km (26.7 miles), approved channel extender products and
telecommunications lines are required.
Figure 10 Universal Replicator for Mainframe Remote Copy Connection Configuration
The remote copy connection between the primary storage system and secondary storage system
provides three different configurations:
•
Direct connection (see Figure 11 (page 61) )
•
Switch connection (see Figure 12 (page 61) )
•
Extender connection (see Figure 13 (page 61) )
