What is a Mainframe Server?
A mainframe server is a very large and powerful server used
to control a large portion of a enterprise. There are only a
few companies that produce true "mainframe servers."
Mainframes are sometimes called "Enterprise Servers" or
"Super Computers." While the term server can refer to
hardware or software, mainframe server always refers to ha



Chassis and Operating System
Mainframe servers often resemble a refrigerator. They are
extremely large machines composed of the most technical
equipment known to the networking industry. Mainframe
servers include an array of CPU's, memory, and disk drives.
They have hot-swapable power supplies, and uninterrupted
power supplies all built in to the machine. Companies like
IBM, Sun Microsystems, HP, SGI, and Cray produce some of the
most powerful mainframe computers on the planet. Most of
these machines run some type of proprietary Operating
System. For instance, the Cray SV1 system runs an OS called
UNICOS. IBM mainframes can run a variety of OSes but they
commonly run OS/390, z/OS, or AIX UNIX. All mainframe OSes
are some derivative of UNIX compiled to support the
extremely powerful architecture of these machines. These
machines do use Pentium or AMD CPU's of any type. They
contain special CPU's designed for mathematical algorithms.
The image below shows a picture of an IBM mainframe server.

Mainframe Usage
You might wonder what a mainframe server is used for? While
its use is limited, a mainframe server can be used as a file
server for a very large organization (this usually means the
government or government contracted organizations). Large
universities and research organizations also use mainframes
for various projects. Mainframes can be clustered together
to harness the power of multiple servers and perform a
single task
