The blade server is a low-cost server platform of High Availability High Density (HAHD). It is designed for special application industries and high-density computer environments. Each "blade" is actually a system mother. Board, similar to a separate server.

　　In this mode, each motherboard runs its own system, serving a different set of users, with no association. However, you can use system software to aggregate these boards into a single server cluster. In cluster mode, all motherboards can be connected to provide a high-speed network environment that can share resources and serve the same user base.

　　The design features of the blade server give it many advantages. The low-power design of the blade server saves a lot of energy and reduces energy consumption. The small footprint and high-density computing save space effectively, which saves a lot of space costs for enterprises with tight room space or server hosting. The blade server adopts a centralized management method, which simplifies the management of the server and reduces maintenance costs. Finally, using a blade server to construct a server cluster, which is easy to maintain and manage, is the most suitable for constructing a cluster. It can be said that it fundamentally overcomes the shortcomings of the chip server cluster, and is called the terminator of the cluster.
