– James Caulker, spokesperson for  Aspen Systems (www.aspensystemsdirect.com), says:
A blade server has the power of a rackmount server but without the space. Standard rackmount servers are measured in U, equal to 1.75 inches in height, and although they limit the amount of floorspace needed, they still occupy an adequate amount of space. A blade server is far more freeing and provides less limitations.
Those interested in purchasing blade servers should consider the following advantages:

Less Space Necessary

The most obvious advantage of a supermicro blade server is the amount of space it doesn’t require. A blade server is far more space conscious; the bulkiness and physical mass of a server is greatly reduced.  A blade server is stripped of excess components but still has the capacity and power that a server provides. In fact, a blade server is far more efficient because it still has the capabilities of a standard server in a far more compact form.

Power and speed

The sheer power of a blade server is unrivaled. Although blade servers may appear less powerful due to the minimization in size, they actually have more capacity capabilities than a standard server. The ergonomic design does not negatively impact the actual server’s strength in any way, shape, or form. A blade server has the best socket density per unit space. Enhanced performance is significantly recognizable with a blade style server. Depending on the actual blade server, some are available with upwards of 40 sockets per 7U. Blade servers with more density show an impressive increase of 42% per 1U – that is nearly 50% more power than a standard server. This establishes that blade style servers are far more dense than some of the densest 1U servers.

Not only does the increased density mean more energy and power, it also means more space and capability. With 1.2 terabytes of memory per 7U, a blade server is a tiny powerhouse. Efficient design and extraordinary power makes a blade server an advantageous purchase.

Combine these technical attributes with the fact that there is over 1.2 terabytes of memory per 7U footprint, blade style servers offer an astounding amount of configuration options to meet the most demanding needs.


An important feature that makes blade servers an excellent choice is the cost-effectiveness. A blade server is less expensive but also reduces management costs, which really add up, thus making it a smart money-saving purchase. Blade servers are far more economical than a standard server. Powerful servers require an incredible amount of energy to sustain them. Energy costs can be incredibly money draining but a blade server is designed to need less energy output. Especially modern blade style servers, are built with less energy needs. Finally, backplanes of blade servers are the same across each, thus less power is wasted between nodes.
