The invention discloses an intel? A management method of NVMe hard disks belongs to the technical field of server hard disk backplanes. The intel? The management method of NVMe hard disk is through I2C? switch chips PCA9546 and I2C? The expander chip TCA6408 sends SMBUS, PRESENT and IFDET information of the hard disk to the BMC for analysis and processing, the BMC outputs another path I2C, and the TCA6408 generates a driving signal of a state indication LED lamp. Intel? The management method of the NVMe hard disk is simple to operate, saves the hardware cost, can effectively manage the temperature, the VPD value, the health information, the fault and other information of the hard disk, and has good popularization and application values.
Description
Technical field
The present invention relates to server hard disk back plane technical field, a kind of management method of intelNVMe hard disk is specifically provided.
Background technology
At present, along with the fast development of cloud computing and large data, many applications are all had higher requirement to the literacy etc. of memory device.Originally traditional AHCI standard and SATA are for mechanical hard disk, cannot play the advantage of solid state hard disc.Since in March, 2011, NVMe1.0 standard was issued, NVMe hard disk is subject to the favor of high-end storage application with advantages such as its low delay, low-power consumption, high read or write speeds.Current intel has released 3 sections of NVMe hard disks such as P3500, P3600 and P3700, and expectation will improve its firmware in the third season in this year, and the SMBUS of hard disk will comprise its temperature, VPD value, health and fitness information, fault information etc. when the time comes.Can predict, the coming years, NVMe hard disk will progressively become the main flow of server application.
In the face of emerging NVMe hard disk, with regard to server design, need to determine its management method, realize the monitoring to information such as the LED of disk state and hard disk backboard end and instruction.
Summary of the invention
Technical assignment of the present invention is for above-mentioned Problems existing, provides a kind of simple to operate, saves hardware cost, and effectively can manage the management method of the intelNVMe hard disk of hard disk.
For achieving the above object, the invention provides following technical scheme:
A kind of management method of intelNVMe hard disk, by I2Cswitch chip PCA9546 and I2Cexpander chip TCA6408, SMBUS, PRESENT and IFDET information of hard disk is delivered to BMC to resolve and process, BMC exports another road I2C, is produced the drive singal of status indicator LED lamp by TCA6408.Monitoring to information such as the LED of disk state and hard disk backboard end and instruction can be realized by described method, hardware cost can be saved, and effectively can manage the information such as temperature, VPD value, health and fitness information, fault of hard disk.
As preferably, described I2Cexpander chip TCA6408 works in input state, and described TCA6408 works in output state.
As preferably, described SMBUS contains temperature, VPD value, health and fitness information, the fault information of hard disk; PRESENT and IFDET can be used to judge the hard disk that the SFF-8639 interface of hard disk backboard connects and drives type.
The present invention has following outstanding beneficial effect: save the demand to control MCU on backboard, and hard disk input information transmission is to host B MC process; Realizing, on the basis to effective management of NVMe hard disk, saving hardware cost.
Accompanying drawing explanation
Fig. 1 is the management method schematic diagram of the intelNVMe hard disk before improving;
Fig. 2 is the management method schematic diagram of the intelNVMe hard disk after improving;
Fig. 3 is the schematic diagram of the management method of intelNVMe hard disk of the present invention.
Embodiment
Be described in further detail below in conjunction with the management method of drawings and Examples to intelNVMe hard disk of the present invention.
In the present invention, when not doing contrary explanation, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings; " inside and outside " refers to profile inside and outside relative to each parts itself.
Embodiment
Be illustrated in figure 1 the management method schematic diagram of the intelNVMe hard disk before improvement, composition graphs 2 and Fig. 3 and Fig. 1 contrast, the management method of intelNVMe hard disk of the present invention, by I2Cswitch chip PCA9546 and I2Cexpander chip TCA6408, SMBUS, PRESENT and IFDET information of hard disk is delivered to BMC to resolve and process, BMC exports another road I2C, is produced the drive singal of status indicator LED lamp by TCA6408.Monitoring to information such as the LED of disk state and hard disk backboard end and instruction can be realized by the method, hardware cost can be saved, and effectively can manage the information such as temperature, VPD value, health and fitness information, fault of hard disk.Wherein I2Cexpander chip TCA6408 works in input state, and TCA6408 works in output state.SMBUS contains temperature, VPD value, health and fitness information, the fault information of hard disk; PRESENT and IFDET can be used to judge the hard disk that the SFF-8639 interface of hard disk backboard connects and drives type.
The practical work process of the management method of intelNVMe hard disk of the present invention is:
1) number of the NVMe hard disk managed as required, selects the chip number of PCA9546 and TCA6408;
2) according to the I2C link load situation of BMC on actual mainboard, choose reasonable input information and the I2C link of output information and the I2C address of IC chip;
3) according to demand, the integrated process code to hard disk information in BMCFW;
4) hardware circuit of this Managed Solution is completed according to the structure of Fig. 3.
PCA9546 is the I2Cswitch chip that 4 tunnels turn 1 tunnel, and the SMBUS of 4 NVMe hard disks is transferred to 1 road I2C signal and exports BMC to by it.TCA6408 is 8 road I2C/GPIOexpander chips, PRESENT and the IFDET information of four hard disks is transferred to 1 road I2C signal and exports BMC to by the TCA6408 of input, these two kinds of information on BMC process I2C0 link, in the temperature, health and fitness information etc. of host side display hard disk, and produce state control information, TCA6408(output mode is exported to by I2C1 link), 6408 resolve the control signal producing status indicator LED lamp.
Above-described embodiment, just the present invention's more preferably embodiment, the usual change that those skilled in the art carries out within the scope of technical solution of the present invention and replacement all should be included in protection scope of the present invention.
