Rack Configurations; Power Distribution - HP 6100 User Manual

Unique frame and rail design — Allows fast assembly, easy mounting, and outstanding
structural integrity.
Thermal integrity — Front-to-back natural convection cooling is greatly enhanced by the
innovative multi-angled design of the front door.
Security provisions — The front and rear door are lockable, which prevents unauthorized
entry.
Flexibility — Provides easy access to hardware components for operation monitoring.
Custom expandability — Several options allow for quick and easy expansion of the racks to
create a custom solution.

Rack configurations

Each system configuration depends on the number of disk enclosures included in the storage system.
For more information about racks and configurations, including expansion and interconnection,
see the HP Enterprise Virtual Array Hardware Configuration Guide.

Power distribution

AC power is distributed to the rack through a dual Power Distribution Unit (PDU) assembly mounted
at the bottom rear of the rack. The characteristics of the fully-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%).
60-Hz and 50-Hz wall receptacles.

IEC 309 receptacle, 3-wire, 30-A, 50-Hz
The standard power configuration for any Enterprise Virtual Array rack is the fully redundant
configuration. Implementing this configuration requires:
◦ Two separate circuit breaker-protected, 30-A site power sources with a compatible wall
receptacle (see
One dual PDU assembly. Each PDU connects to a different wall receptacle.
◦
Six Power Distribution Modules (PDM) per rack. Three PDMs mount vertically on each
◦
side of the rack. Each set of PDMs connects to a different PDU.
◦ The drive enclosure power supplies on the left (PS 1) connect to the PDMs on the left with
a gray, 66 cm (26 in) power cord.
◦ The drive enclosure power supplies on the right (PS 2) connect to the PDMs on the right
with a black, 66 cm (26 in) power cord.
