The DCS3700 storage subsystem with Performance Module Controllers series controller modules can have
up to eight host ports, depending on the configuration, as shown in the following figure:
The host ports on the DS4200 and DS4700 (model 72) controller module are numbered from left-to-right
on controller B as Ch 1, Ch 2, Ch 3, and Ch 4. Controller A, which is installed upside-down in the
enclosure, is numbered from right-to-left in the same sequence, as shown in the following figure:
