Can be NVME hard disks；Hard-disk slots are NVME hard-disk slots；Aforesaid operations system can be (SuSE) Linux OS.Also
It is to say, the NVME hard-disk slots start on host can support NVME hard disk hot-plug functions after entering (SuSE) Linux OS, i.e.,
NVME hard-disk slots can be inserted into any NVME hard disks or any NVME hard disks of renewal.
According to foregoing description, specifically, perform step S101 and memory money is directly carried out to the hard-disk slots on host in advance
When distribution is reserved in source, following steps can be specifically included：
SBIOS directly distributes correspondingly sized memory source to the NVME hard-disk slots on host in advance.
Then, hard disk driver after step S102 enters operating system is performed to be carried out accordingly according to reserved memory source
During distribution, following steps can be specifically included：
NVME drivers can be reserved according to SBIOS needed for NVME hard disks in linux system after into (SuSE) Linux OS
Memory source carry out related distribution.
Afterwards, perform after hard-disk slots of the step S103 on host are assigned to memory source and carry out hard disk hot-plug processing
When, following steps can be specifically included：
The NVME hard-disk slots that Switch converters connect under linux system carry out heat after storage allocation resource and insert
Pull out processing.
Finally, accessed NVME equipment can be recognized after NVME hard-disk slots connection hard disk and system is normal.
Wherein, hot plug processing is carried out, can specifically be included：NVME hard disks are directly inserted in any vacant NVME hard disks
In groove position, the NVME hard disks being inserted into NVME hard-disk slots are identified；Or, directly carry out the renewal of NVME data in hard disk.
