Introduction To Servers
A server is any computer or computer program (in this post we’ll be focusing on the computer systems) with the ability to provide functionality to any system/program which are called “clients”. The “functionalities” are usually referred to as services and they include data and resource sharing among clients and carrying out complex calculations. Now we move on to the types, there are three types of servers: the Blade,Tower and Rack Servers.
Blade Servers are servers which have their unnecessary parts removed to conserve physical space, they can consist of up to 180 servers per system. Due to their ability to contain large numbers of servers, they are used for specific purposes like web hosting, virtualization and cluster computing. They have a number of issues despite their advantages; high power usage, ventilation and air conditioning among others.
Tower Servers are computers which are intended for use as servers, they are built in upright cabinets similar to tower personal computers. This is the major difference between them and and other types of servers which are rack mounted by default. They are easier to cool due to their design and encourages a very large number of units to be added. The only problems involved are cable complexity, weight and each units requires a dedicated fan.
Rack Servers are computers dedicated for use as servers they are installed in frameworks called “racks”, there are multiple slots for mounting called “bays” for each individual server to be installed. This minimizes floor space, consolidates network resources and simplifies wiring. Heating is the major disadvantage for this server type.
