Compaq ProLiant DL360 Ultra-Dense Server Deployment in Compaq Racks

Compaq ProLiant DL360 Ultra-Dense Server Deployment in Compaq Racks 40
128H-1100B-WWEN
3.5 Configuration-E: 36 Full-rated Servers, Low
Voltage
This configuration shows a 42U rack with a maximum number of servers in a low voltage
facility. If high voltage input is available, then this configuration is not recommended, because
fewer than 42 ProLiant DL360 servers will be supported in a 42U rack, considering the maximum
input current rating for the servers. In N.A., assuming 110V line voltage, only up to 36 servers
can be supported with 4 Low Voltage 24A PDUs. In Japan, assuming 100V line voltage, only up
to 32 servers can be supported with 4 Low Voltage 24A PDUs. This example configuration is
illustrated here for the N.A. market.
Note that up to 4 Compaq Low Voltage PDUs can be installed in the sides of a Compaq 36U or
42U racks. Each ProLiant DL360 server can consume up to 2.7A @110V, i.e., each 24A PDU
can support up to 9 ProLiant DL360 servers. Therefore, with 4 Low Voltage 24A PDUs, only up
to 36 servers can be supported.
Note that up to 42 servers may be installed, if the deployment plan can support de-rated power for
each ProLiant DL360 server power supply. See Section 3.4.
The remaining space in a 42U rack is available for other devices, such as network switches. If no
network switches are installed in this rack, then there will be several standard network cables
exiting the rack, which are to be routed to appropriate off-rack switches. In the configuration
summary below, all network switches are located outside of the rack.

Configuration-E Summary
Rack Contents
Units
36 servers with all fixed or all sliding rails with cable trays
4 Low Voltage 24A PDUs vertically mounted in the side panel compartments
Internal Cables
36 power cords going to 4 PDUs in the side panels [These cables are supplied
with the servers.]
Cables External to Rack
36 (management) network cables from the optional Remote Insight Lights-Out
Edition RJ-45 connector to external switches
36 (data) network cables from on-board RJ-45 to external switches, assuming
use of only one LAN connection per server.
4 input power cords from the rack to external power outlets
Site Utility Requirements (worst-case)
Power: 4 dedicated 100V-120V 30A branch circuits.
Thermal: up to 35,850 BTUs/hour [This number is a worst-case. The actual
BTUs/hour will depend on the OS/application software running and the server
hardware configurations.]
Weight: up to 1,518 lb (with sliding-rails) [The network cables are not
accounted for since most implementations route the network cables to the
ceiling-hung cable rails outside of the rack.]
