Storage System Racks
All Enterprise Virtual Array 3000 components are mounted in the storage system
rack. The available racks are the Enterprise Racks and the Rack System/E racks.
The rack configuration is determined by the number of disk enclosures being
used. Multiple storage systems can be installed in a single rack. For more
information about storage system racks and configuration information, including
expansion and interconnection, refer to the HP StorageWorks Enterprise Virtual
Array Hardware Configuration Guide.
Power Distribution
The power distribution components differ between the Enterprise racks and the
Rack System/E racks. See “
Enterprise Racks Power Distribution Components ” on
page 129 or “ Rack System/E Power Distribution Components ” on page 133.
For either rack, the characteristics of the full redundant rack power configuration
are as follows:
■ Each PDU is connected to a separate circuit-breaker-protected, 30-A AC site
power source (220–240 VAC ±10%, 50 or 60 Hz, ±5%).
Figure 55 illustrates
the compatible 60-Hz and 50-Hz wall receptacles.
Figure 55: 60-Hz and 50-Hz wall receptacles
Note: If local regulations forbid use of these receptacles, you must change the
connectors on the PDU power cords.
■ The standard power configuration for the storage system rack is a fully
redundant configuration. Implementing this configuration requires:
— Separate circuit-breaker-protected, 30-A site power sources with a
compatible wall receptacle. See Figure 55 .
