Campus Topology - HP Surestore Disk Array 12h - And FC60 Advanced User's Manual

Campus Topology

The campus topology uses the same hardware components as the high availability,
distance, and capacity topology. The components for each instance of this topology
include:
• Up to four host systems or servers
• Two Fibre Channel I/O adapters per host
• Two pairs of cascaded 10-port HP Fibre Channel-AL Hubs
• Two controller modules per disk array
• Maximum of nine dual-controller module disk arrays
• Maximum 500 m fibre optic cable distance on each connection between each host and
HP Fibre Channel-AL Hub and between each HP Fibre Channel-AL Hub and disk array,
for a total Fibre Channel-AL cable length not to exceed 5000 m
This topology is almost identical to the high availability, distance, and capacity topology.
The difference is that in the campus topology one-half of the host systems, HP Fibre
Channel-AL Hubs, and disk arrays are located in one building while the other half of the
hosts, HP Fibre Channel-AL Hubs, and disk arrays are located at another site. The
distribution of systems and hardware between two physical sites provides protection
against a power failure or some other catastrophic site-wide failure.
