IBM Blade Center
IBM
International Business Machines Corporation (IBM, or
colloquially, Big Blue; NYSE: IBM) is a computer technology firm
headquartered in Armonk, NY, USA. The company, which was founded in
1888 and incorporated June 15, 1911, manufactures and sells computer
hardware, software, infrastructure services, hosting services, and
consulting services. IBM is the biggest information technology company
in the world and holds more patents than any other tech company.
With almost 332,000 employees worldwide and revenues of $91 billion
annually (figures from 2005), IBM is also one of the few information
technology companies with a continuous history dating back to the 19th
century. It has engineers and consultants in over 170 countries and
development laboratories located all over the world, in all segments
of computer science and information technology; some of them are
pioneers in areas ranging from mainframe computers to nanotechnology.

Blade servers are self-contained computer servers,
designed for high density. Whereas a standard rack-mount server
can exist with (at least) a power cord and network cable, blade
servers have many components removed for space, power and other
considerations while still having all the functional components
to be considered a computer. A blade enclosure provides services
such as power, cooling, networking, various interconnects and
management - though different blade providers have differing
principles around what should and should not be included in the
blade itself (and sometimes in the enclosure altogether).
Together these form the blade system.
In a standard server-rack configuration, 1U (one rack unit, 19"
wide and 1.75" tall) is the minimum possible size of any equipment.
The principal benefit of, and the reason behind the push towards,
blade computing is that components are no longer restricted to these
minimum size requirements. The most common computer rack form-factor
being 42U high, this limits the number of discrete computer devices
directly mounted in a rack to 42 components. Blades do not have this
limitation; densities of 100 computers per rack and more are achievable
with the current generation of blade systems.
