Description

Hard disk backboard and server

Technical Field

The cost performance of a server can be greatly improved if the server can meet different requirements, so that the compatibility can be improved in all aspects as much as possible during server development.

In the traditional backplane design, the mapping relationship between nodes and hard disks is generally fixed, and the signal of one hard disk is from only one node, so the number of hard disks corresponding to one node is also fixed, and generally, the number of hard disks corresponding to each node is also the same. However, as the customer demand increases, the number of hard disks mapped by the same node may be different when corresponding to different service scenarios, and for the hard disk backplane, a requirement that different nodes need different numbers of hard disks is also provided. The number of hard disk interfaces on one hard disk back plate is fixed, and on the basis of fully utilizing all hard disks, the hard disks on the back plate need to be flexibly distributed to nodes. Due to the limitation of the traditional backboard design scheme, the requirements of customers cannot be well met, the scheme needs to be changed according to the requirements of the customers, the main board needs to be matched with a plurality of hard disk backboards with different designs, the research and development cost and the labor input are increased, and the cost performance of the main board is greatly reduced.
