Description

technical field

[0001] The invention belongs to the technical field of server memory expansion, and in particular relates to a system and method for realizing high-density server memory pool expansion. Background technique

[0002] With the rapid development of servers, there are more and more application fields of servers, and the demand for hard disk capacity, memory capacity, number of GPUs, and number of CPU cores of servers is increasing. With the increasing demand for CPU functions, the CPU package is getting bigger and bigger. The current CPU package size has reached 102mmx142mm, resulting in a normal 2U (2x44mm) 2-way server motherboard unable to meet the 24 (2DPC) from each CPU, a total of 48 Therefore, a normal 2U2-socket motherboard can only support 24 sticks of memory, that is, 12 sticks per CPU (1DPC).

[0003] The standard size of a traditional 2U2-way motherboard is 425mm wide. The size of the new CPU package plus 24 (2DP) memory is 277mm, and the size of the...
