Locating Servers
Servers are among the most important components of a business network, and
the
locations you select for them depend on who will be responsible for their
daily oper-
ation and maintenance. In any case, servers should be more physically secure
than
workstations, and they should have protection against power spikes and
interruptions.
Some networks have departmental servers, and administrators prefer to
physically
place them in the individual departments, leaving each group of workers
responsible
for its own server. This policy generally affords less physical security for
the server and
creates a greater risk of unauthorized access to the computer itself.
Whenever possible,
you should locate departmental servers in locked closets, with appropriate
power pro-
tection and environmental controls. In some cases, the utility closet on
each floor of a
building, containing the hubs and patch panels, also functions as a server
closet.
Other organizations prefer to place all their servers in a single data
center, where pro-
fessional administrators can maintain them. This is often a preferable
solution because
the data center is usually easier to secure physically and typically has
sufficient power
and environmental controls already.
