Embodiment one
With the issue of the server architecture of intel a new generations, each manufacturer server all sets in new server architecture
The support of the solid state hard disc NVMe SSD of U.2 interface type is counted.NVMe SSD are used as a kind of new high performance solid state hard disc
The read or write speed of storage medium is greatly improved, while shortening the access time between CPU 4 and storage medium.For
U.2 solid state hard disc brings using upper convenience when hot plug is provided.
With reference to Fig. 2 and Fig. 3, for supporting there are three class schemes in the U.2 scheme of the solid state hard disc NVMe SSD of interface type：
NVMe Switch, retimer card and onboard FPGA, although such scheme is also brought using upper relatively flexible simultaneously
Some other problems, such as operating system cannot obtain solid state hard disc NVMe SSD corresponding No. BayID on front panel, from
And hard disk 1 cannot be in use accurately positioned, and a kind of method of the mark of identification hard disk 1 of the embodiment of the present invention can
Solid state hard disc can be accurately positioned when solid state hard disc is particularly using multiple hard disks 1, be operated on it with facilitating.
A kind of method of the mark of identification hard disk 1 of the embodiment of the present invention, applies in smart machine, as shown in figure 1, should
Method includes：Headspace is distributed in hard disk 1 particularly solid state hard disc, and the mark storage of hard disk 1 will be distributed to reserved
In space.The headspace can be independently of the memory space of other hard disks 1, and user can not when using 1 data storage of hard disk
In storing the data to the headspace；The headspace can also be what factory was divided when the hard disk 1 is produced to it
Space (such as smartlog), the headspace can be with characteristics such as the title of storage hard disk 1, capacity and temperature for intelligence
Equipment reads and uses, and this is designated the valid data that can determine corresponding hard disk 1.
With reference to Fig. 1, the method also includes the System Management Bus 5 of identity map to hard disk 1, from System Management Bus 5
Middle identification mark.The System Management Bus 5 of hard disk 1 are the communication trunk between hard disk 1 and smart machine, and it includes multiple points
Branch such as SMbus1 and SMbus2 etc., smart machine can be operated and controlled by the System Management Bus 5 to hard disk 1,
The mark that will be distributed for hard disk 1 first is stored in headspace, then by the System Management Bus 5 of the identity map to hard disk 1,
Specially by the register of the identity map to System Management Bus 5, and the mode for mapping can be effective by the mark of hard disk 1
System Management Bus 5 are delivered to, and many hardware devices are connected with System Management Bus 5, therefore the mark can be very
Easily recognized by other hardware devices, the identification to identifying is meant to being accurately positioned to corresponding hard disk 1, for example
CPU 4 effectively can be managed after recognizing the mark to the hard disk 1, can be smart in multiple hard disks 1 when breaking down
It is determined that there is mistake in which hard disk of position 1, so as to replacing in time.
In one embodiment, it is the allocation identification of hard disk 1 by BIOS.BIOS (not shown)s are needed to smart machine
All of hardware is identified and registers, and can be it when BIOS recognizes hard disk 1 to carry out the management of bottom to hardware
Allocation identification, for example, hard disk 1 distribute PCIe slot ID, and this No. ID is the EBI ID of smart machine (such as server)
Number, the method for above-mentioned allocation identification can be realized by changing the program in BIOS.In another embodiment, it is being hard disk
Can also be distributed by other hardware devices during 1 allocation identification, it is also possible to realized by various ways such as active uploads.

Front panel BayID), logical identifier distributes to the virtual mark for not representing actual on-position of hard disk 1 for smart machine
Know, and physical label includes the step of then can be identified for that the actual installation position of hard disk 1, identification marking：It is total by system administration
The recognition logic of line 5 is identified, and it is total that it can be mapped directly to system administration by the logical identifier by above-mentioned steps from headspace
On line 5, therefore can be by the Direct Recognition of System Management Bus 5 logical identifier.It is total by system administration for physical label
Line 5 recognizes physical label from the corresponding backboard 2 of hard disk 1, and in one embodiment, backboard 2 has multiple slots, each slot
With corresponding numbering, multiple hard disks 1 may be mounted on the slot of backboard 2, and the backboard 2 can recognize every piece of reality of hard disk 1
The location on border, that is, be capable of identify that the physical label of hard disk 1, and backboard 2 is also connected on System Management Bus 5, so that
By System Management Bus 5 physical label can be recognized from the corresponding backboard 2 of hard disk 1.
In one embodiment, methods described also includes corresponding logical identifier and physical label, to position hard disk
1.The step causes that each hard disk 1 is respectively provided with logical identifier and corresponding physical label, both is corresponded further bright
The true identity information of hard disk 1, so that the operating system of smart machine using multiple hard disks 1 when solid state hard disc is particularly
Each hard disk 1 can be accurately identified, particularly it is capable of identify that the BayID of the front panel of each hard disk 1, it is to avoid in the prior art
Needs manually check the problem that can learn its BayID.
The System Management Bus 5 of identity map to hard disk 1 there are into various methods, can be in actual content persistent data form
The mode of change is mapped to System Management Bus 5, and the corresponding data of the mark after change can effectively be known by System Management Bus 5
Not, it is also possible to read by other equipment by System Management Bus 5, in one embodiment, identity map is arrived in this method
The step of System Management Bus 5 of hard disk 1, is specifically, the mark that will be stored in headspace copies System Management Bus 5 to
In register, direct copying saves the process of data mode change, improves mapping efficiency, and direct copying is easy and effective in addition does not allow
Made a mistake when easily causing data transfer, it is ensured that the reliability of data.

1 mark such that it is able to be accurately positioned hard disk 1.
In one embodiment, BIOS is further configured to the allocation identification of hard disk 1.It is right that BIOS (not shown)s need
The all of hardware of smart machine is identified and registers, to carry out the management of bottom to hardware, when BIOS recognizes hard disk 1
Can be its allocation identification, for example, hard disk 1 distribution PCIe slot ID, this No. ID is the total of smart machine (such as server)
Line interface ID, the method for above-mentioned allocation identification can be realized by changing the program in BIOS.In another embodiment,
Can also be distributed by other hardware devices when for 1 allocation identification of hard disk, it is also possible to realized by various ways such as active uploads.
In one embodiment, mark includes logical identifier (such as PCIe slot ID) and physical label (such as hard disk 1
Front panel BayID), logical identifier distributes to the virtual mark for not representing actual on-position of hard disk 1 for smart machine
Know, and physical label then can be identified for that the actual installation position of hard disk 1, management module is further configured to total by system administration
The recognition logic of line 5 is identified, and it is total that it can be mapped directly to system administration by the logical identifier by above-mentioned steps from headspace
On line 5, therefore can be by the Direct Recognition of System Management Bus 5 logical identifier.For physical label, management module is by being
Reason bus 5 under the overall leadership recognizes physical label from the corresponding backboard 2 (BP) of hard disk 1, and in one embodiment, backboard 2 (BP) has
Multiple slots, each slot has corresponding numbering, and multiple hard disks 1 may be mounted on the slot of backboard 2, and the backboard 2 can be with
Every piece of actual location of hard disk 1 of identification, that is, be capable of identify that the physical label of hard disk 1.As shown in Figures 2 and 3, one
