Historically, when the demand on a server got too great,
another server was purchased and slid beside the first one and
took up the incremental demand. As demands grew, more
servers were purchased and real estate in computer rooms was
quickly becoming a scarcity. Imagine a room full of identical
boxes in rows.

The principal behind blade server technology is efficiency. The
concept is to simplify, and blade accomplishes this through
sharing resources. In typical rack mounted servers, each server
has its own I/O, its own storage, its own processor, its own
power supply - each could stand and operate by itself.

What this means is that to increase performance from your rows
of servers - you not only bought more processors, you bought
more of everything… whether you needed it or not!

With Blade Technology, common elements that all the servers
can"share" are brought together. With blade, there is a single
power supply, a single I/O bus, shared cooling, a single network
connection and every time you want to add the equivalent of a
new server - a board is slid into the rack and joins all the other
"boards" - (said BLADES) in the rack. Need more performance?
Add another blade. You don't buy another backplane or another
power supply or another Ethernet connector - they are already
there… simply buy what is needed to incrementally meet/exceed
existing demands.

From one central point, every element in the environment is
monitored and every new item added is managed in the same
fashion. Simplify cabling. Simplify power. Simplify space
management. Simplify shared components. Simplify and
save.

Save through lower cost to operate, manage and maintain. Save
through more effective and efficient use of existing investments
in technology. Save through lower costs to upgrade, deploy and
rollout. Simplify and save.
