StorageWorks Product Speciﬁcations

This appendix chapter describes the physical and environmental speciﬁcations for

the StorageWorks products. See the Digital Systems and Options Catalog for the

operating speciﬁcations for storage devices, controllers, and host computers.

A.1 Input Power Requirements

The input power requirements for a StorageWorks enclosure are determined by

the number of shelves, the enclosure power distribution units, the fans, and other

features.

A.2 Power Units

Each StorageWorks shelf requires an ac or dc power unit. The power unit type is

determined by the enclosure power system, either ac or –48 V dc.

All shelves can have a redundant power unit to ensure that a power unit

failure does not disable the shelf. In most cases, battery backup units (BBUs)

can be combined with the shelf power unit to provide extended system data

integrity. See the following table and StorageWorks Family User’s Guide for more

information about the power units.

Table A-4 contains the speciﬁcations for the BA35X–HA, the BA35X–HB, and the

BA35X–HC StorageWorks power units.
