Ultra-Dense Server Deployment in Racks

Compaq Ultra-Dense Server Deployment in Compaq Racks 51
128H-0400A-WWEN
3.13 Configuration-M: 22U Rack, 22 Servers, High Voltage
This configuration shows a “best practice” for Compaq 22U racks with 22 servers in a high voltage
facility. Remote console management via the optional Remote Insight Lights-Out Edition is
recommended. The network cables are routed to the network switches located off-rack.
Configuration-M Summary
Rack Contents
Units
22 servers with all fixed or all sliding rails with cable trays
2 High Voltage 24A PDUs vertically mounted in the side panel compartments
Internal Cables
11 Y-power cords going to 2 PDUs in the side panels
Cables External to Rack
22 (management) network cables from the optional Remote Insight Lights-Out
Edition RJ-45 connector to external switches
22 (data) network cables from on-board RJ-45 to external switches, assuming
use of only one LAN connection per server.
2 input power cords from the rack to external power outlets
Site Utility Requirements (worst-case)
Power: 2 dedicated 200V-240V 30A branch circuits.
Thermal: up to 21,900 BTU [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 940 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].
