What is Blade computing and Blade server?

A Blade server is a server chassis containing server computers called server blades which are designed for high performance in less storage space. The difference between ordinary rack mount servers and blade servers is that all the power needs of the entire system is provided by the chassis as one single unit thereby eliminating the need for separate power cords for each server maintained. Other cable requirements are also eliminated. Thus a blade server saves space, which is a significant factor in modern computing era.

The consolidation of power supplies also reduces the total power consumption since individual power supplies to each server is not required. All the resources are centralized which results in lower management cost.It is easy to upgrade and add new servers. All that is needed is to slide the new servers into chassis space.

Each server blades contain 1 to 4 processors with ample memory racked in the blade chassis. One can also add additional memory modules outside the system. The entire system can be centralized by removing memory modules from server blades and adding one single external memory module. This can eliminate data redundancies too.

Server management tools and virtualization software comes in the software part which enables the server administration and ensures proper and maximum server utilisation.
