Third-Party/Existing Rack Mounting; Service Installation Prerequisites - HP 3PAR StoreServ 7450c Planning Manual

6 Third-Party/Existing Rack Mounting

Some installations may use third-party or existing racks to house the HP 3PAR StoreServ 7450
Storage components. Install system components only into a standard 19-inch rack. The rack must
also be equipped with the appropriate PDUs or power receptacles and have access to an adequate
power source that provides the recommended level of redundancy.
For site administers who choose to mount storage system components, the following kits are
available:
7450 Node Enclosure
Drive Enclosure
Service Processor
NOTE: For physical dimensions and power/heat specifications for storage system components,
see "Power and Heat Specifications" (page

Service Installation Prerequisites

Location of Rack
Place the rack in its final location.
Make sure the operational power, with the correct connectors, exists in the proposed location
of the rack. The system will operate in 100-240VAC 50/60Hz and requires 200-240 VAC
PDUs or power strips. Each drive enclosure requires two C13/C14 connections. The SP
requires one C13/C14 connection.
36 inch (91.4 cm) of service clearance is required directly in front of the rack. This is required
due to the depth of the enclosure and potential to damage to other equipment that is in front
of the rack/enclosure.
30 inch (76.2 cm) of service clearance is required on both sides of the front of the rack. This
is required because two people must lift the enclosure and set into the rack. The allocated
space is necessary on each side for the person to stand and maneuver the enclosure.
30 inch (76.2 cm) of unobstructed clearance is required directly behind the enclosure to
service the nodes (for example, do not attach PDUs, power-strips, power cord routing, and
other things to the back of the rack). There must be unobstructed clearance directly behind
the node enclosure in order to remove or install a controller node.
Rack Requirements
The rack is operational and has enough space for the installation. HP installation and upgrade
services does not include building a new rack, re-racking, or moving existing components.
The required contiguous rack space is defined by the quantity of 7450 Storage and drive
enclosures in the system. There must be 2U of rack space for each HP 3PAR 7450 Storage
enclosure and 2U SAS drive enclosure, 4U of rack space for the 4U SAS drive enclosure, and
1U for a service processor. HP also recommends having an open rack space above and below
the installed storage system components for drive enclosure upgrades.
Only use a 4-post rack for an installation. Using any other types of racks is prohibited . The
vertical RETMA rails must have square holes.
