Heterogeneous hybrid memory server architecture

Abstract

The invention discloses a heterogeneous hybrid memory server architecture which comprises a CPU (central processing unit) computation board and an NVM (non-volatile memory) board. CPU chips are arranged on the CPU computation board and are connected with DRAM (dynamic random access memory) chips; master FPGA (field programmable gate array) chips are arranged on the NVM board and are connected withthe DRAM chips and NVM memory bars; the CPU chips are connected with the master FPGA chips by QPI (quick path interconnect) bus; the global cache consistency of non-volatile memories can be maintained by the master FPGA chips, and accordingly global memories can be shared. The heterogeneous hybrid memory server architecture has the advantages that each NVM with low power consumption and high capacity is used as a far-end memory, each DRAM with low capacity and high speed is used as a near-end memory, and accordingly heterogeneous hybrid memory systems with high capacity and low power consumption can be constructed; addresses are compiled for the heterogeneous memories in a unified manner, accordingly, the problems in the aspects of heterogeneous memory system coupling and speed matching can be solved, and the global data consistency can be maintained; the heterogeneous hybrid memory server architecture is high in memory capacity and CPU access efficiency and low in power consumption.

Description

technical field [0001] The invention relates to the field of memory server architecture, in particular to a heterogeneous hybrid memory server architecture. Background technique [0002] Existing computers all use the method of reading data from the memory, but with the vigorous development of big data, cloud computing and other technologies, people put a large amount of data into the memory for analysis and calculation, which makes the memory capacity of the traditional mode Problems such as limited power consumption and high power consumption have become more and more prominent. At the same time, there is still the problem of low data processing speed due to I / O performance mismatch between the existing computer memory and external memory. Contents of the invention [0003] In order to solve the above problems, the present invention provides a heterogeneous hybrid memory server architecture with large capacity and high access efficiency. [0004] The technical solution...
