Cluster Architecture 2-23 Figure 2-10 shows an acceptable method for cabling the I/O path components in a quad redundancy configuration. In this example, the following connections are made: I Each of four host adapters in each node connects to the same-numbered Fibre Channel SAN Switch (host adapter #1 to Fibre Channel SAN Switch #1, host adapter #2 to Fibre Channel SAN Switch #2, host adapter #3 to Fibre Channel SAN Switch #3, host adapter #4 to Fibre Channel SAN Switch #4). I The two odd-numbered Fibre Channel SAN Switches connect to port 1 of the array controllers. Fibre Channel SAN Switch #1 connects to array controller A, port 1 in each storage subsystem. Fibre Channel SAN Switch #3 connects to array controller B, port 1 in each storage subsystem. I The two even-numbered Fibre Channel SAN Switches connect to port 2 of the array controllers. Fibre Channel SAN Switch #2 connects to array controller A, port 2 in each storage subsystem. Fibre Channel SAN Switch #4 connects to array controller B, port 2 in each storage subsystem.
