Description
Technical field
The present invention relates to field of data storage, more particularly to a kind of setting method, system, one kind of NVME hard disk hot-plugs
Computer readable storage medium and a kind of GPU servers.
Background technology
With the development of science and technology, conventional central processor, that is, CPU (Central Processing Unit centres
Reason device) it cannot be satisfied to requirement of real-time higher big data progress quickly and effectively calculation process demand, while emerging skill
The ripe demand to GPU (Graphics Processing Unit, graphics processor) server of art artificial intelligence concept
It increases, therefore results in each manufacturer server and strongly increase R＆D intensity to GPU servers.Simultaneously to critical data business
Requirement and the requirements such as processing, storage it is also higher and higher, capacity and power consumption and the NVME (Non-Volatile of common hard disc
Memory express, a kind of theaflash protocol) all there is disadvantage in hard disk comparison, and the advantages of NVME hard disks is mainly reflected in lower
Time delay, higher data transmission, lower power consumption control, memory capacity are big etc., therefore use Switch chips can be same
When support GPU and NVME scheme receive artificial intelligence associated companies extreme favor.
In the prior art, occur NVME hard-disc storages insufficient space or in advance peace when GPU servers are in service operation
The NVME hard disk numbers of dress are inadequate, at this moment need replacing new NVME hard disks and cannot influence business normal operation, therefore NVME is warm
Plug function just seems increasingly important.But the realization of NVME warm connection functions not only needs the support that linux system drives, BIOS
(Basic Input Output System, basic input output system) similarly needs to support NVME warm connection functions, usually
Hot plug NVME hard disk functions are normal after when NVME hard disks connect, booting enters linux system, but when NVME hard disks are not connected
Hot plug will produce mistake after being switched on into linux system, and all NVME hard disks can all be lost at this time.In such a scenario to interconnection
The service operation of net company can cause detrimental effects.
Therefore, it is this hot plug operations of NVME hard disks how to be carried out under the premise of ensureing that the data of GPU card are not lost
The current technical issues that need to address of field technology personnel.

Flow chart.
Specific steps may include：
S101：It is phase according to the system topology of the GPU servers before GPU servers enter linux system
The NVME slot bit allocation memory sources answered；
Occur NVME hard-disc storages insufficient space or preassembled NVME hard disks when GPU servers are in service operation
Number is inadequate, at this moment needs replacing new NVME hard disks and cannot influence business normal operation, therefore NVME warm connection functions are just shown
It obtains increasingly important.Therefore, the present embodiment is to solve the NVME hard disk hot-plugs after entering linux system to influence business from normal
The problem of operation.
If it is understood that under normal conditions when NVME hard disks have connected, it is switched on and enters linux system, then into
The operation of row hot plug NVME hard disks does not interfere with the normal operation of business.But NVME hard disks are opened when not connect with corresponding interface
Hot plug will produce mistake after machine enters linux system, and NVME hard disks all at this time can all be lost, and traffic affecting is normally transported
Battalion.
Wherein, GPU servers may include polylith GPU card and polylith NVME hard disks, not hard to GPU card and NVME herein
The quantity of disk is specifically limited, and those skilled in the art can carry out appropriate according to the practical application scene of this programme
Setting.Since a GPU server can correspond to multiple NVME hard disks, that is to say, that there may be corresponding numbers on GPU servers
NVME slot position of the amount for installing NVME hard disks, NVME hard disks are connect by being mounted on NVME slots position with GPU servers.Value
It obtains it is noted that being to the NVME slot bit allocation memory sources all with hot plug demand, as a kind of preferred in this step
Embodiment, can be each NVME slots position mean allocation preset byte length memory source.Certainly, it is that NVME is specific
How many memory source are distributed, are to be selected according to practical situations by those skilled in the art, herein without specific
It limits.
S102：It, will be described using NVME drivers after the GPU servers enter the (SuSE) Linux OS
Memory source needed for NVME hard disks is assigned to corresponding NVME hard-disk interfaces, to carry out hot plug behaviour to the NVME hard disks
Make.
Wherein, after entering (SuSE) Linux OS, (SuSE) Linux OS can be according to the memory source reserved in S102
Related distribution is carried out, hot plug operations can be carried out after NVME slot bit allocation memory sources.NVME vacant slots connect
