6. HP Representative: Install the URz remote copy connections between the primary storage
system(s) and secondary storage system(s). This hardware (optical fibre cables, switches, etc.) is
supplied by the user.
See “Setting up Remote Copy Connections” on page 65 for remote copy configurations. Distribute
the paths between different storage clusters and switches to provide maximum flexibility and
availability. The logical paths between the primary storage system and secondary storage system
must be separate from the logical paths between the host and secondary storage system.
Setting up Remote Copy Connections
Figure 9 on page 65 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-m
ode long wave support. For distances greater than 43 km (26.7 miles), approved channel
extender products and telecommunications lines are required.
