When receiving data processing command, pending data corresponding with the data processing command is determined, and the pending data is divided into
At least two subdatas generate subcommand corresponding at least two subdatas.That is: each subdata is corresponding with a son
Order, the subcommand include an address mapping relation, and it is corresponding to be used to indicate the physical address that the subdata stores before transmission
The corresponding memory space of physical address to be stored, the subdata are needed by the address in subcommand after memory space and transmission
Mapping relations transmission.Since each subdata is corresponding with address mapping relation required when respective data are transmitted, in this way,
When carrying out data transmission, subdata to be transmitted is divided by electronic equipment to be transmitted several times, when transmitting each time, therefore, to assure that each
In the corresponding subcommand of subdata in address mapping relation the corresponding memory space of physical address state, determine that this time needs to pass
Defeated subdata, and transmitted by the address mapping relation in the subcommand for the subdata determined.Upon completion of the transmission, into
Row transmits next time when, equally, reflected based on address in the corresponding subcommand of subdata each in the remaining subdata that do not transmit

Relationship, specifically, the address mapping relation in the corresponding subcommand 1 of subdata 1 is from the physical address 1 of host memory to NVMe
The physical address 3 of hard disk, the address mapping relation in the corresponding subcommand 2 of subdata 2 be from the physical address 2 of host memory to
The physical address 1 of NVMe hard disk；Address mapping relation in the corresponding subcommand 3 of subdata 3 be from host memory physically
The physical address 1 of NVMe hard disk is arrived in location 3.When carrying out data processing, firstly, determining that each subdata needs the NVMe stored hard
The corresponding working condition of physical address in disk.Such as: at current time, the physical address 3 of NVMe hard disk is busy state, NVMe
The physical address 1 of hard disk is idle state, and the physical address 2 of NVMe hard disk is busy state, at this point, electronic equipment determines this
The subdata of secondary transmission is subdata 3, and subdata 3 is written to NVMe hard disk physically by the physical address 3 of host memory
Location 1.After the completion of subdata 3 is written, electronic equipment confirms what the remaining digital data 1 that do not transmit and subdata 3 to be stored again
The corresponding working condition of physical address in NVMe hard disk, at this point, the NVMe hard disk in address mapping relation corresponding with subdata 1
Physical address 3 be idle state, the physical address 2 of the NVMe hard disk in address mapping relation corresponding with subdata 2 is non-
Idle state, at this point, electronic equipment determines that the subdata of this transmission is subdata 1, by subdata 1 by the physics of host memory
Address 1 is written to the physical address 3 of NVMe hard disk.After the completion of subdata 1 is written, finally by subdata 2 by host memory
Physical address 2 is written to the physical address 2 of NVMe hard disk.The write operation of pending data is completed in this way.
It similarly, is that pending data is read out into host memory by hard-disc storage space when handling the read operation of data
Memory space, mode is the same with the out-of-order transfer mode of above-mentioned write operation, here, the application does not repeat them here.It follows that subnumber
It can be subdata 3, subdata 1, subdata 2 with out-of-order transfer, transmission sequence according to.And in the prior art, subdata is necessary
Sequential delivery, it is necessary to transmit subdata 2 after first etc. subdatas 1 have passed, then transmit subdata 3.
By above-mentioned example it is found that in the present embodiment, for the read-write operation of data, data to be read and write can be decoupled
At multiple subdatas, generate subcommand corresponding with multiple subdatas, so in transmission consideration storage state by subdata into
Row out-of-order transfer, reduces data delay.Without having to sequential delivery as the prior art.Thus it is possible to effectively solve existing
The technical issues of delay larger with the presence of reading and writing data in technology, realizes the technology effect quickly and efficiently handled data
Fruit.
