With the development and progress of server technology, some servers will have tens of large-capacity hard disks for storing a large amount of data, and the power consumption of each hard disk is generally about 12 watts, so that it can be seen that in a data storage server, the power consumption of the hard disk accounts for a large proportion of the power consumption of the whole server. When the server is powered on and started, if all the hard disks are powered on simultaneously, and the power supply has the problem of surge current, the power-on instantaneous current is too large, impact can be brought to power supply equipment, and even potential safety hazards can be caused.

Since different CPLDs may be on different I2C buses, and each register controlling power on/off of a hard disk in different CPLDs controls power on/off of a hard disk in different slots, when controlling power on/off of one or some hard disks, it is necessary to perform a correspondence through complex calculation, and then write the calculated data into the corresponding register in the corresponding CPLD using the I2c-test tool.

IPMI (Intelligent Platform Management Interface) is based on Management
The industrial standard adopted by the peripheral equipment used in the enterprise system with the structure is that a user can monitor physical health characteristics of the server, such as temperature, voltage, fan working state, power state and the like, by using IPMI, and can also develop own IPMI command to control and set other equipment modules on the server, and the BMC can perform read-write operation on equipment on an I2C bus on a mainboard. The BMC reads and writes the registers which correspondingly control the power on and power off of the hard disk in different CPLDs through I2C bus communication, so that the corresponding power on and power off of the hard disk can be realized.
The embodiment of the invention can directly set the number of the power-on blocks of the server hard disk by using an IPMI command, then calculates according to the set number of the power-on blocks, the total number of the hard disks on each hard disk backboard, the number of the hard disk blocks in each row, the hard disk sequence controlled by each register in the hard disk backboard CPLD, the total number of the hard disks in each row of the hard disk array and other data, and finally obtains the control data to be written in each hard disk backboard CPLD.
Generally, register data of the CPLD is one byte, namely 8 bits, and can control up and down of 8 hard disks at most. Assuming that a server is provided with N hard disk backplanes, each backplane corresponds to a CPLD control chip on an I2C bus, and the hard disk array on each backplane is m rows by N rows (N is less than or equal to 8), the total number of hard disks in each row is w-N; setting the number of the powered-on hard disk blocks as k, making a equal to k/w, b equal to k% w, c equal to b/n, d equal to b% n, a representing the number of hard disk rows needing to be powered on completely, that is, the number of registers needing to be written with all power-on control data on each hard disk backplane CPLD, b representing the number of hard disk blocks needing to be powered on in the a +1 th row, c representing the number of backplane blocks needing to be powered on in the a +1 th row, and d representing the number of hard disk blocks needing to be powered on in the a +1 th row and the c +1 th backplane. Where k/w represents the integer portion of k divided by w, and k% w represents the remainder portion of k divided by w.
And setting the total number of the hard disk blocks electrified in each group and the time interval between the two groups of electrified hard disk blocks. The embodiment of the invention firstly develops an IPMI command which can set the hard disk to be powered on and powered off, and the IPMI command is sent to set the number of blocks to be powered on by the server when the server is powered on and started.
And judging whether the set total hard disk block number is effective or not. In some embodiments, determining whether the set total number of hard disk blocks is valid comprises: and judging whether the set total number of hard disk blocks exceeds a hard disk threshold value of each power-on. For example, the threshold of the hard disk for each power-on is 100, and if the set total number of hard disk blocks is 150, the set total number of hard disk blocks is invalid. In some embodiments, determining whether the set total number of hard disk blocks is valid further comprises: and judging whether the set total number of hard disk blocks exceeds the total number of the hard disks of the server.
And responding to the fact that the set total hard disk block number is effective, calculating the number of the totally electrified hard disk lines and the number of the non-totally electrified hard disk lines based on the total hard disk block number, and setting corresponding first electrifying data based on the totally electrified hard disk line numbers. And after receiving the command, the BMC analyzes the command and judges whether the set number of the power-on blocks of the hard disk is valid, if so, the BMC stores the number of the power-on blocks of the starting hard disk of the server into the power-down nonvolatile memory chip, and if not, an error code is returned to prompt the operation and maintenance personnel of the server to set errors. When the server is powered on and started, the hard disk control program reads the set number of the hard disk power-on blocks from the power-down nonvolatile memory chip, firstly judges whether the parameter is valid or not after reading, if the parameter is invalid, the hard disk control program considers that the parameter is not set, and calculates the next step according to the default of all power-on; and if the parameters are valid, calculating the number a of the hard disk rows which need to be completely electrified according to the parameters. and a is k/w, when k can divide w completely, the number of the hard disk rows which are not all powered on is 0, and when k cannot divide w completely, the number of the hard disk rows which are not all powered on is 1. The hard disks in the first a rows need to be completely powered on, control data does not need to be calculated, and the number of the hard disk blocks needing to be powered on in the (a + 1) th row needs to be calculated. That is, the first power-on data is written into the corresponding CPLD without calculation.
And judging whether the number of the rows of the hard disks which are not completely electrified is one, responding to the number of the rows of the hard disks which are not completely electrified being one, and calculating second electrified data corresponding to the number of the rows of the hard disks which are not completely electrified. In some embodiments, calculating second power-on data corresponding to the number of rows of the hard disks which are not powered on completely comprises: calculating the number of all electrified back plate blocks and the number of non-all electrified back plate blocks in the number of non-all electrified hard disk rows, and calculating the electrified data of all electrified back plate control hard disks; judging whether the number of the non-all electrified back plate blocks is one; and responding to the situation that the number of the backboard blocks which are not all electrified is one, and calculating the data of controlling the electrification of the hard disk by the backboard which is not all electrified. B hard disks in front of the a +1 th row of hard disks need to be electrified, the number of the backboard blocks which need to be controlled to be electrified in the a +1 th row is calculated according to the c ═ b/n, namely CPLD registers corresponding to the c hard disk backboard in front of the a +1 th row write in all electrified control data, and then the data of electrification control of the a +1 th row and the c +1 hard disk backboard are calculated. The number of the hard disk power-on blocks on the a +1 th row and the c +1 th backboard is calculated according to d ═ b% n, and then the data bit 1 represents power-on and the data bit 0 represents power-off so as to calculate the data for controlling the power-on of the hard disk, for example, d ═ 5, then the data for controlling the power-on of the hard disk on the a +1 th row and the c +1 th backboard is 0x 1F. 0x1F represents 00011111, i.e. 5 hard disks powered up.
Because the k hard disks are powered on before being controlled, the k hard disks to the m × N hard disks are all controlled to be powered off, and according to the calculation process, all the hard disks from the c +1 hard disks to the N back plates in the a +1 row need to be controlled to be powered off, the 1 st hard disk from the a +2 row to the m hard disk back plates need to be controlled to be powered off, and 0x00 can be directly written into the corresponding CPLD register.
And powering on the corresponding hard disk based on the first power-on data and the second power-on data. In some embodiments, powering up the corresponding hard disk based on the first power-up data and the second power-up data includes: the BMC writes the first power-on data and the second power-on data to the corresponding CPLDs through the I2C bus respectively so as to control the corresponding hard disks. After calculating the register control data for controlling the power on and power off of each hard disk in each CPLD in the process, the BMC writes the data into the CPLDs respectively and correspondingly through I2C bus communication. When the server is powered on, the CPLD of each hard disk backboard controls the power switch of the hard disk according to the power-up and power-down control data bit corresponding to each hard disk in the register, so that the control of the number of power supply blocks of the hard disk is realized during the startup, the off-peak power-up of the server is further realized, and the stable output of the power supply of the server is facilitated. Such as: a certain server is provided with 120 hard disks, the power consumption of each hard disk is 12 watts, and the power consumption of the whole server is 2000 watts. When the number of the power-on blocks of the server startup hard disk is not set, all the hard disks are defaulted to be powered on, and the power consumption of the hard disks is 1440 watts; if the first 10 hard disks are powered on when the computer is started and the rest 110 hard disks are not powered on when the computer is started, the power consumption of the hard disks during the startup is 120 watts, and the power consumption of the whole computer is 680 watts. Therefore, the embodiment of the invention can greatly reduce the starting power consumption of the server and greatly improve the power output stability of the server.
When receiving a setting command for setting the power-on block of the hard disk of the server, the method also records the information of the number of the power-on blocks of the hard disk, the time for receiving the command and the like into a local log file; after the control data are calculated, the data sent to each CPLD are recorded into a local log file, so that the hard disk is well documented in the process of controlling power on and power off.
And responding to the time interval between the two groups of power-on, and powering on the next group of hard disks. In some embodiments, powering up the next set of hard disks comprises: and calculating the number of the totally electrified hard disk lines and the number of the non-totally electrified hard disk lines based on the total number of the hard disk blocks and the number of the totally electrified hard disk blocks of the next group, and setting corresponding first electrified data based on the number of the totally electrified hard disk lines. After the BMC detects that the startup is finished, the rest hard disks which are not electrified are electrified again according to the above process, for example, the first 10 hard disks are electrified by sending a command for the first time, the first 20 hard disks are electrified by sending a command for the second time (actually, the first 10 electrified hard disks +10 newly electrified hard disks), and the like, and the off-peak electrification effect of the server is realized by the analogy of control. Of course, the number of hard disk blocks powered on each time may also be different, for example, the second command is sent to control the first 30 hard disks to be powered on (actually, the first 10 powered-on hard disks +20 newly powered-on hard disks).
The above embodiments are described below by way of a specific example:
let m be 3, N be 4, N be 10, and k be 105. Then W-N-40.
Firstly, the number of rows a of all powered-on hard disks and the number of rows of non-all powered-on hard disks are calculated, wherein a is equal to k/w equal to 2, b is equal to k% w equal to 25, and b is not equal to 0, so that the number of rows of non-all powered-on hard disks is 1, that is, the hard disk in the 3 rd row is partially powered-on.
And then, calculating the number c of all the electrified back panel blocks and the number of all the electrified back panel blocks in the number of the rows of the hard disks which are not electrified, wherein c is b/n is 6, and d is b% n is 1, so that the first 6 back panels in the 3 rd row are all electrified, and a hard disk is electrified on the 7 th back panel.
Fig. 2 is a flowchart illustrating an embodiment of a method for off-peak power-up of a server hard disk according to the present invention. As shown in FIG. 2, beginning at block 101 and proceeding to block 102, the total number of hard disk blocks powered up for each group and the time interval between powering up the two groups are set; then, go to block 103, judge whether the total hard disk block number is valid, if yes, go to block 104, if not, end directly; a block 104, calculating the number of rows of all powered-on hard disks and the number of rows of non-all powered-on hard disks based on the total number of hard disk blocks, and setting corresponding first powered-on data based on the number of rows of all powered-on hard disks; proceeding to a block 105, determining whether the number of the non-all-powered hard disk rows is one, if so, proceeding to a block 106, calculating second powered-on data corresponding to the number of the non-all-powered hard disk rows, then proceeding to a block 108, if not, proceeding to a block 107, powering on the corresponding hard disk based on the first powered-on data, and then proceeding to a block 109; block 108, powering up the corresponding hard disk based on the first power-up data and the second power-up data; proceeding then to block 109, the next set of hard disks is powered up in response to reaching the time interval between powering up the two sets, and proceeding then to block 110, which ends.
It should be particularly noted that, the steps in the embodiments of the method for powering up a server hard disk in a peak-off manner may be mutually intersected, replaced, added, or deleted, and therefore, the method for powering up a server hard disk in a peak-off manner through reasonable permutation and combination shall also belong to the scope of the present invention, and shall not limit the scope of the present invention to the embodiments.
