Description

A kind of Novel extending module realizing expanding system internal memory based on QPI bus

Technical field

The utility model relates to calculator memory expansion technique field, specifically a kind of Novel extending module realizing expanding system internal memory based on QPI bus.

Background technology

Along with internet, large data and the arriving in virtual epoch, more and more higher requirement is proposed to the capacity that inside computer system stores.In the processing of traditional computer architecture, processor is connected with memory extender by SMI link, and processor generally only has four groups of SMI links to carry out memory expansion, along with the explosive growth of current data volume, need the speed increase that the data of processor process become geometric, virtualized application is simultaneously more and more extensive, need the interior storage capacity that system provides larger, therefore there is very large restriction by means of only the mode of SMI link exented memory at present, be difficult to meet the demand that current data increase widespread use.Therefore, in the urgent need to developing a kind of Novel extending module, to meet the demand of market end for big data quantity process.

Summary of the invention

Technical assignment of the present utility model is for the deficiencies in the prior art, a kind of Novel extending module realizing expanding system internal memory based on QPI bus is provided, it is strong and use the feature of dirigibility that this Novel extending module has both extendability, can meet the demand of market end for big data quantity process.

The utility model solves the technical scheme that its technical matters adopts:

A kind of Novel extending module realizing expanding system internal memory based on QPI bus, comprise memory expansion chip and memory extender, memory expansion chip and memory extender are arranged on corresponding installation position, described memory expansion chip uplink port is connected with the QPI bus of multipath server, memory expansion chip downlink port is connected with memory extender, and memory expansion chip comprises QPILink interface sub-module, logical transition submodule and internal memory SMILink interface sub-module;

QPILink interface sub-module is connected with memory expansion chip uplink port, for receiving the QPI signal that multipath server sends;

Logical transition submodule sends to internal memory SMILink interface sub-module after being used for that the QPI signal received is changed into eight groups of smi signals;

Internal memory SMILink interface sub-module is connected with downlink port, for reading data or write data in memory extender according to group smi signal of eight after logical transition, and the data read is sent to logical transition submodule.

Further, described memory extender supports binary channels.

Further, each described passage supports two physical memory dimm sockets.

Further, described multipath server comprises multiple processor, three groups of interconnected QPILink of express passway supported by each processor, and wherein two groups of QPILink are for carrying out the interconnection between multiple described processor inside, remain one group of QPILink and are connected with the uplink port of memory expansion chip.

Further, described each processor carries memory extender.

Further, described memory expansion chip and/or memory extender are connected with corresponding installation position by hot plug mode.

A kind of Novel extending module realizing expanding system internal memory based on QPI bus of the present utility model, compared with prior art, the beneficial effect produced is:

The utility model is by being directly connected Novel extending module with the QPI bus of Intercommunication between processor, after converting eight groups of SMI links to, the expansion as required of local system internal storage data is realized by collocation memory extender, thus improve existing system internal data storage capacity, simultaneously, this expansion module supports the plug-and-play operation of hot swap type, has both and uses dirigibility and the strong feature of extendability.
