4.8.1
Drive Port Connectivity in a Dual-Controller Array
Drive channels connect to the internal drives in the array and can also connect to
drives in external expansion units. The key difference between the SANnet II 200 FC
and SATA array drive channels is the assignment of two ports for each channel:
drives in external expansion units. The key difference between the SANnet II 200 FC
and SATA array drive channels is the assignment of two ports for each channel:
■
The SANnet II 200 FC array has a drive channel assigned to two ports on each
I/O controller module. Each drive channel is a pair of ports on a single I/O
controller module. In a dual-controller configuration, the top controller has two
ports for drive channel 2, and the lower I/O controller module has two ports for
drive channel 3.
