Compaq ProLiant DL360 Ultra-Dense Server Deployment in Compaq Racks

Compaq ProLiant DL360 Ultra-Dense Server Deployment in Compaq Racks 60
128H-1100B-WWEN
3.14 Configuration-N: 22U Rack, Low Voltage PDU
This configuration shows a maximum number of ProLiant DL360 servers in a Compaq 22U rack
in a low voltage facility. If console management is done via the optional Remote Insight Lights-
Out Edition then all network switches to where the network cables connect can be located in the
same rack or elsewhere.
As explained in Section 2.4, a 24A Low Voltage PDU can support up to nine full-rated
ProLiant DL360 servers. Therefore, with two 24A Low Voltage PDUs, 18 servers can be
supported.
The configuration summary below is for the 18-server configuration.
22 servers can be used if the servers’ power budget is de-rated as follows
:
The maximum current draw for each server when a 24A Low Voltage PDU is used to
support 11 servers will be as follows:
Maximum input current per server = 24A / 11 servers = 2.19A @ 110V
That means the maximum input power each server can consume will be
2.19A * 110V = 241W
The maximum thermal dissipation per server will be
241W * 3.41 = 822 BTUs/hour
For 22 servers, the total thermal dissipation will be (822*22=) 18,084 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 241W, then 22 servers can be supported via this configuration summary.
