Abstract

The invention provides a system and a method for realizing memory pool expansion of a high-density server. The system comprises a server mainboard board card and a memory expansion card; the server mainboard board card is provided with a CPU, the CPU is provided with an integrated memory controller and a PE port, and the integrated memory controller is connected with an integrated memory; the memory expansion card is provided with a memory rapid controller, and the memory rapid controller is connected with an expansion memory; and the memory fast controller is connected with a PE port of the CPU. According to the system and method for realizing memory pool expansion of a high-density server, memory expansion is achieved through cooperation of the CPUs and the memory rapid controller; the invention can be used for a single CPU or multiple CPUs, the original scheme that only server board cards can be added for memory adding is avoided, cost is reduced, cache consistency between the CPUs can be improved, the PE port resources of the CPU are more balanced, and the performance of the CPU is developed to the greatest extent.

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...
