Embodiment Construction

[0027]The following embodiments of the present application provide a memory expansion system and method. In a multi-processor-designed system, when the processing capability meets the requirements but the memory capacity requirement exceeds the capacity of the processor's built-in memory, the memory expansion system can Install expansion chips on other processor installation positions to replace the processor, and install the required expansion memory on the memory installation position of the processor installation position where the expansion chips are located, so that the existing processor can communicate with the expansion chip through the QPI interface Communication is carried out to realize the access to the extended memory connected to the extended chip, so it can solve the problem that the existing multi-processor design server expands the memory capacity by adding processors to cause redundant processing capacity.

[0028] In order to enable those skilled in the art t...

Abstract

An embodiment of the invention discloses a memory extending system and a memory extending method. The system comprises processors, extended memories, extended chips and multiple processor installation positions, and a memory installation position is arranged at each process installation position; the processor installation positions are connected mutually through QPI (quick path interconnect) interfaces, at least one processor installation position is provided with a processor, and at least one of the rest installation positions serves as extended installation position; the extended chips are installed in the extended installation position; the extended memories are installed to the memory installation positions connected with the extended chips. The memory extending system has the advantages that the extended chips are mounted at other processor installation positions to replace the processors, and the existing processors are enabled to be capable of accessing the extended memories carried by the extended chips through the extended chips, so that memory capacity of the existing processors is increased on the condition that processing capacity is not improved, and the problem of processing capacity redundancy caused by the fact that memories are extended by adding processors in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of information storage, in particular to a memory expansion system and method. Background technique [0002] For a computer system, the computing power of the processor, the memory capacity, and the bandwidth of the input / output interface are three important performance evaluation indicators. In order to improve computing power, the system needs to configure high-performance processors, such as multi-core multi-thread processors, and often multiple processors are interconnected to form SMP (Symmetrical Multi Processing, Symmetrical Multi-Processor) or NUMA (Non Uniform Memory Access, non-uniform memory access) structure to achieve concurrent business processing. In order to expand the memory capacity, the processor usually integrates multiple memory controllers, and each controller can support multiple memory sticks. Combined with the above-mentioned multi-processor technology, the memory capacity...
