HSV controller cabling
All data cables and power cables attach to the rear of the controller. Adjacent to each data
connector is a two-colored link status indicator. Table 5 (page 16) identifies the status conditions
presented by these indicators.
NOTE: These indicators do not indicate whether there is communication on the link, only whether
the link can transmit and receive data.
The data connections are the interfaces to the disk enclosures or loops (depending on your
configuration), the other controller, and the fabric. Fiber optic cables link the controllers to the
fabric, and, if an expansion cabinet is part of the configuration, link the expansion cabinet disk
enclosures to the loops in the main cabinet. Copper cables are used the controllers (mirror port)
and the controllers and the disk enclosures or loops.
Storage system racks
All storage system components are mounted in a rack. Each configuration includes one controller
enclosure holding both controllers (the controller pair), FC cables the controller and the disk
enclosures. Each controller pair and all associated disk enclosures form a single storage system.
