Setting up Remote Copy Connections
Figure 3-1 shows the remote copy connection configurations for URz operations. The primary storage system and secondary storage system of each URz 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. URz 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. URz 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.
