ProLiant DL360 G2 Server High-Density Deployment

ProLiant DL360 G2 Server High-Density Deployment 30
Configuration C: Traditionalist (28 Servers, Low-Voltage)
The following calculation verifies supporting 28 servers (de-rated Power Budget) with 24 A
low-voltage PDUs:
Since there are 4 PDUs supporting 28 servers, 4 KVM switches, 2 Ethernet switches, 2 Ethernet
hubs and (1) 1U Keyboard/Monitor, each PDU needs to support up to 18 devices. A 24 A
low-voltage PDU supporting 8 servers can allocate each server with maximum current of (24/8=)
3.0 A. Assuming 110 V, the allocated maximum input power for each server will be:
3.0 A * 110 V = 330 W
The maximum thermal dissipation per server will be:
330 W * 3.41 = 1,125 BTUs/hour
For 28 servers, the total thermal dissipation will be (1,125*28=) 31,508 BTUs/hour
.
In the “Measured Input Power” section of this document, a fully configured system was measured
to consume lower than 250 W (Table 6, Server Configuration 4). If each de-rated server
configuration input power is lower than 330 W, then 28 servers can be supported via this
configuration summary.

Configuration C Summary
Rack Contents
Units
28 servers with all fixed or all sliding rails with cable trays
4 low voltage 24 A 0U/1U PDUs
2 x 48 port Ethernet switches
2 x 24 port Ethernet hubs
4 KVM switches
1 x 1U Keyboard/Monitor
Internal Cables
36 power cords going to 4 PDUs in the side panels [These cables are supplied with the servers.]
32 KVM cables going from switch to server, switch to switch and switch to 1U Keyboard/Monitor
28 (management) network cables from the Integrated Lights-Out Edition’s RJ45 connector to two 24 port 10/100
Ethernet hubs
56 (data) network cables from the on-board 10/100/1000 NICs’ RJ-45 connectors to two 48 port Ethernet switches
each with 44 10/100T ports and 4 gigabit ports, assuming use of two LAN connections per server
Cables External to Rack
4 low voltage input power cords connecting from the PDUs to facility AC power feeds
Site Utility Requirements (worst-case)
Power: 4 dedicated 100 V-120 V 30 A branch circuits.
Thermal: up to 31,508
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 1,690 lb [The network cables are not accounted for since most implementations route the network
cables to the ceiling-hung cable rails outside of the rack.]
