By moving servers out of the computer room and
into cabinets Kell Systems has improved energy efficiency and space
According to management consultancy Accenture, the
energy expenditure required to cool servers is as much as the energy
required to power the servers themselves, pushing up company cooling
budgets, and in turn carbon emissions.
One solution to this problem is to ditch the traditional computer room,
and to house servers, and other network infrastructure, in cabinets.
Server cabinets developed by Kell Systems use forced-air cooling to keep
temperatures under control, and to ensure that noise levels are low
enough for the cabinets to be usable in the open office, thus removing
the need for dedicated air-conditioned server room facilities
In a typical usage case, Kellís cabinets reduce perceived server noise
by up to 90 per cent, CO2 emissions by 96.5 per cent, floor space by 90
per cent, operating costs by 98 per cent, and capital costs by 65-80 per
cent, when compared to a conventional server room (based on typical
office with servers, switches, patching, UPS, KVM and tape backup).
If a typical 3.6 kW server room installation were replaced with an
equivalent Kell ComputerVault Pro cabinet deployed in the open office,
hardware cooling costs can be reduced by £1,300 per annum (calculation
based on a conservative price of 10p per kW/hour).
Whilst server manufacturers are bringing out new energy efficient
models, unless introduced alongside a strategy that can reduce the cost
of cooling them, only a fraction of the potential energy cost savings
can be achieved. Server cabinets enable companies to meet this demand
for cost-effective cooling.
How it works
Kell server cabinets operate on a principle of fresh-air cooling, where
ambient air is drawn in at floor level of the enclosure, channelled over
the front of the equipment, and then extracted out of the enclosure at
the rear. Located out in the open office they do not need the dedicated
air-conditioning of equivalent server rooms, as any heat generated is
dispersed indiscernibly into the large body of air of the office.
An analogy to explain the energy dispersal might be that if you drop
some ice cubes into a large bath of water, the temperature change to the
bath water is negligible, but if you drop the same ice cubes into a your
drink, the temperature drop is substantial. In a similar way, small
computer rooms require dedicated air conditioning because warm air from
the equipment is pumped into a small, confined space, so heat builds up
very quickly. While conceptually simple, this approach requires high
standards of manufacturing and assembly to ensure successful results.
