An HP Blade Server is different from a typical rack based server in that the the enclosure actually provides the cooling, connectivity, power and management to each of the blades within the chassis. Each HP Blade server only contains the core processing elements making it a much more efficient server configuration. Each HP Blade server is also hot swappable. Because cooling, connectivity and power elements are shared between all of the Blades within the enclosure, each HP Blade server does not need to include those parts individually.
Each HP Proliant Blade contains numerous I/O cards, hot plug hard drives, memory, multi function network interconnects and remote management. HP Blades can connect to other storage blades for additional storage capacity.
