Compaq ProLiant DL360 Ultra-Dense Server Deployment in Compaq Racks

Compaq ProLiant DL360 Ultra-Dense Server Deployment in Compaq Racks 51
128H-1100B-WWEN
BEST PRACTICE
3.10 Configuration-J: 36U Rack, 36 De-rated
Servers, High Voltage
This configuration is a recommended "best practice" for a high voltage facility (N.A. only) where
36 ProLiant DL360 servers are to be installed in a 36U rack.
There are 36 servers and 2 PDUs. Therefore, each PDU will need to support 18 servers. A 24A
High Voltage PDU supporting 18 servers can allocate each server with maximum current of
(24/18=) 1.34A.
Assuming 208V, the allocated maximum input power for each server will be
1.34A * 208V = 279W
The maximum thermal dissipation per server will be
279W * 3.41 = 952 BTUs/hour
For 36 servers, the total thermal dissipation will be (952*36=) 34,272 BTUs/hour.
In Section 2.2, a fully configured system was measured to consume lower than 200W (Table 2-3,
Server Configuration-5). Hence, if each de-rated server configuration input power is lower than
279W then 36 servers can be supported via this configuration summary.
Remote console management via Remote Insight Lights-Out Edition is recommended when
deploying a large number of servers, such as this configuration. The network cables are routed to
the network switches located off-rack. This configuration still allows the use of a “walk-up” local
console, where a person can walk up to the rear of the rack and plug in a set of KVM cables to a
particular server.
