NUMA (Non-Uniform Memory Access Architecture), the basic feature of NUMA server is that it has multiple CPU modules, each CPU module is composed of multiple CPUs (such as 4), and has independent local memory, I/O slots, etc. .
Because of the connectivity and information exchange between the nodes through the interconnect module, each CPU accesses local memory faster than the shared memory and other CPU local memory. Therefore, letting the upper layer perceive NUMA, the allocation of resources within the node, can significantly improve performance on data and specific tasks or user-related business servers.
