Ultra-Dense Server Deployment in Racks

Compaq Ultra-Dense Server Deployment in Compaq Racks 37
128H-0400A-WWEN
3.6 Configuration-F: 42 Servers, Off-Rack Local Console,
High Voltage
This configuration shows a 42U rack with a maximum number of servers in a high voltage facility with
server management via local console. Therefore, there will be several KVM cables from each server
exiting the rack, which are to be routed to KVM (Server Console) switches located off-rack. This
configuration is not recommended because of long/bulky KVM cables and the inability to manage
any server from any console.
Configuration-F Summary
Rack Contents
Units
42 servers with all fixed or all sliding rails with cable trays
3 High Voltage 24A PDUs vertically mounted in the side panel compartments
Internal Cables
22 Y-power cords going to 3 PDUs in the side panels
Cables External to Rack
42 sets of KVM cables (126 cables worst-case) from the servers to the
external Server Console Switches
42 (data) network cables from on-board RJ-45 to external switches, assuming
use of only one LAN connection per server
3 input power cords from the rack to external power outlets
Site Utility Requirements (worst-case)
Power: 3 dedicated 200V-240V 30A branch circuits.
Thermal: up to 41,820 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 1,678 lb (with sliding-rails) [The KVM and the network cables
are not accounted for since most implementations route these cables to
the ceiling-hung cable rails outside of the rack.]
