Figure 1–2 RAID Array 3000 6-Slot Device Expansion Shelf (Optional)

SHR-1091

A battery-backup subsystem is included with the Controller Shelf in the form of a rackmount UPS (Uninterruptable Power Supply). In case of a power failure, the UPS provides temporary power to the storage system while it flushes its cache contents to disks. The UPS is normally installed in the lowest available slot in the cabinet.

CAUTION

The UPS is sized to perform this function for the Controller and Device Expansion Shelves only. No other electrical devices should be plugged into the UPS.

As an option, a second RAID controller module can be added for redundancy. The second controller operates in conjunction with the installed controller to protect data in case of a malfunction in the primary unit. The optional controller is installed directly below the primary controller in the center of the shelf.

The RAID Array 3000 Controller Shelf enclosure and its associated options are listed and described in Table 1–1.
