One of
the biggest problems with most data center designs is sizing.
On one hand people talk of having a modular system, which
will give them the flexibility to scale up the center as and
when requirements increase and on the other hand, they go
on to build a data center from day one to cater to all capacity
needs that they may have in the distant future. This leads
to underutilization of resources and ultimately wastage of
money. A better idea is to build a modular data center for
current and near future needs. With a modular system in place
you can increase the capacity of the center as ad when required
in the distant future.
A very important, and most overlooked, criterion while
building a data center is its location, and in most cases
you also do not have much in hand to decide. But still there
are several things you can control. You should not go ahead
and build you center at any available space in the office
building. Factors such as accessibility to the center in
case of an emergency, earthquake, fire and flood and history
of the place, and its ability to accommodate increasing
number of equipment, should be kept in kind. Technology
obsolescence in the computer world happens much faster than
any other field. While you may today have the latest equipment,
they are bound to become obsolete in a matter of 2-3 years.
