Our providers power facilities far
exceeds the investment and design of most
other SME web hosting firms. Rather than leave our customer's Internet
service to chance, they have wisely invested in key power infrastructure
to ensure any loss of utility power, power equipment failures, and
wire cuts do not
result in a loss of service. Over $650,000 has been investing in
power equipment alone!
Ultra Power
Redundancy through Power Equipment, Batteries and Diesel Generators
All of our providers Internet Data Centers (IDCs) fall under their
power facility, consisting of a battery room, a power room, and
generators located outside the building. The battery room consists
of 200 C&W Liberty Series 1000
Lead-Calcium batteries. These batteries weigh 95 pounds each, and
the 4 battery racks total 19,000 pounds. At 100%
load, the batteries will have a 27% run-time.
Currently, they are running at a 10%
load, giving about 9.5 hours of battery
run-time. The power room consists of two 400kVa Liebert Series 600
systems, which are used for power regulation.
Though the batteries could provide the
needed power for an extended time, they are not meant to be a long-term
power back-up solution. The two diesel generators serve the purpose
of providing an extended power alternative to utility service. The
two diesel generators can run about 24
hours without refueling, and a service contract is maintained with
a local fuel company to provide delivery of specified diesel generator
within an hour of a telephone call!
While these generators had to be utilized due to loss of utility
power in the past, they have never needed re-fueling while the utility
power remained out.
How Power
is Delivered to Power your Internet Presence
Our provider's primary source of DC power is the local utility company,
Kansas City Power & Light. If the utility service is unavailable,
the diesel generators provide a long-term
power source alternative. From the power source, the electricity
flows through the Automatic Transfer Switch (ATS). The electricity
then passes through the Liberty 100 batteries in a daisy-chain formation.
From the batteries, the power proceeds up one of the two busbars
within the building. The power is then delivered to one of 3 Power
Distribution Units (PDUs). From the PDUs, the power is then broken
down into individual wiring that runs below the raised floors in
the IDCs to each individual rack or cabinet.
