Lesson 4: Locating Network Resources
One important part of the network infrastructure design process is creating
a blueprint
that specifies the locations of network components. After you have selected
the proto-
cols that the network will use, you have a lot of the information needed to
plot the
locations of network resources, such as the maximum lengths for your cables
and the
number of hubs you can use on each LAN. To complete the blueprint, you need
a dia-
gram of the site where the network is to be installed, as well as some idea
where the
furniture and other fixtures will be located.
After this lesson, you will be able to
■ Understand the criteria used to determine network component locations
■ Plan locations for workstations, peripherals, cables, connectivity
devices, and servers
on your network
Estimated lesson time: 20 minutes
Determining Location Criteria
Creating a network blueprint is not the concern of the IT department alone.
Although
certain technical aspects of the network design would be lost on most
people—such as
the locations of servers and routers—the network blueprint also determines
where the
workstations for the network’s users will be located, and this obviously
concerns the
people responsible for the office floor plan.
The criteria you must consider when planning the locations for network
components
are various. Chief among these is access by users to the equipment they need
to per-
form their jobs. This means that users must have convenient access to
workstations
that are appropriate to their tasks, as well as access to peripheral devices
such as
printers and scanners. However, although user convenience is important,
equipment
must also be easily accessed by technical support and maintenance staff. For
network
infrastructure equipment, such as servers, hubs, and routers, the physical
security of
the devices is another vital factor when creating the blueprint. Finally,
there are the
requirements of the business and its owners, such as cost, appearance,
portability,
and expandability.
Locating Workstations
Assuming that a floor plan for the site already exists that includes the
location of users’
desks and other furniture, it may seem as though locating workstations is
simply a mat-
ter of putting a computer on each desk. Actually, there is a good deal more
to it than
that. Planning also includes determining what type of computer is needed and
exactly
where the equipment should be located in relation to the desk.
