Cluster Architecture 2-17 Table 2-2 identifies the features of the active/standby and active/active configurations for redundant Fibre Channel Fabrics. Table 2-2 Features of Active/Standby and Active/Active Configurations for Redundant Fibre Channel Fabrics I/O Path Configuration Active/standby with one RA4000/RA4100 Array Active/standby with two or more RA4000/RA4100 Arrays Advantage Active/standby is the only I/O path configuration you can use in a redundant Fibre Channel Fabric that contains just one RA4000/RA4100 Array. Provides true cabling symmetry between the Fibre Channel SAN Switches and array controllers. A Fibre Channel SAN Switch connects to the same array controller slot (top or bottom) in every RA4000/RA4100 Array. Disadvantage Load balancing between the two Fibre Channel SAN Switches is less than ideal because the connection to the active array controller in every RA4000/RA4100 Array is routed through the same Fibre Channel SAN Switch. The second Fibre Channel SAN Switch provides no active I/O pathway unless an active array controller or its cable connection to the first Fibre Channel SAN Switch fails. continued
