The EVA8400 requires that disk enclosures be balanced across three loops. With six disk enclosures
in an expansion rack, there should be two disk enclosures per loop. With nine disk enclosures in an
expansion rack, there should be three disk enclosures per loop.
Figure 18

show how
the disk enclosures within each loop are connected in both of these scenarios.
