This configuration has two Fibre Channel switches at the primary site and two Fibre Channel
switches at the secondary site (four switches total), which provide for complete failover and
redundancy. Failures could involve Fibre Channel switches, Fibre Channel cables, and any host or
storage array. Two Fibre Channel switches at each site also provide redundancy to the local site in
addition to a fully redundant remote configuration. No single point of failure exists in the hardware
components.
The following figure shows the highest availability campus configuration. The controller-drive trays
are shown schematically with four host ports on each of two controllers in each controller-drive tray.
In this configuration, use the A4 connection and the B4 connection for remote mirroring traffic
instead of the A2 connection and the B2 connection. You can use controller ports A2, A3, B2, and B3
for additional host access if needed.
