A blade server is a thin, modular electronic circuit board, containing one,
two, or more microprocessors and memory, that is intended for a single,
dedicated application (such as serving Web pages) and that can be easily
inserted into a space-saving rack with many similar servers. One product
offering, for example, makes it possible to install up to 280 blade server
modules vertically in multiple racks or rows of a single floor-standing cabinet.
Blade servers, which share a common high-speed bus, are designed to create
less heat and thus save energy costs as well as space. Large data centers
and Internet service providers (ISPs) that host Web sites are among
companies most likely to buy blade servers.
A blade server is sometimes referred to as a high-density server and is
typically used in a clustering of servers that are dedicated to a single task,
such as:
Web page serving and caching
SSL encrypting of Web communication
The transcoding of Web page content for smaller displays
Streaming audio and video content
Like most clustering applications, blade servers can also be managed to
include load balancing and failover capabilities. A blade server usually comes
with an operating system and the application program to which it is
dedicated already on the board.
Individual blade servers are usually hot-pluggable and come in various
heights, including 5.25 inches (the 3U model), 1.75 inches (1U), and
possibly "sub-U" sizes. (A U is a standard measure of vertical height in an
equipment cabinet and is equal to 1.75 inches.)

Brick server
A brick server is a compact computer server module without a chassis that
can come in various processor, RAM, I/O, and storage configurations and is
designed to fit into rack locations similar to those for blade servers. Like
blade servers, brick servers are intended to fit in multiple numbers into a rack
that provides a shared backplane. Blade and brick servers allow more servers
to be contained in the same floor space than the more conventional pizza
box servers with a chassis. The term, used by Dell and others, suggests that
a brick server, when available, will be more brick-like in shape than a blade
server. Dell refers to it as a "super-blade server."
Pizza box server
The term "pizza box server" refers to the shape of a computer server
enclosed in a rectangular and horizontally-arranged chassis and often
installed in a rack with similar servers. In any country where Italian pizza
can be ordered for home or office delivery, it comes in a box of roughly
the same size as one of these servers.
