detailed description

The embodiments are described below with reference to the accompanying drawings, and the features of the embodiments and the embodiments may be arbitrarily combined with each other without conflict.

In the embodiment of the present disclosure, the plurality of hard disks of the hard disk array are sequentially activated; the startup current of the hard disk is obtained before each hard disk is started, and it is determined whether the sum of the startup current and the current current of the hard disk array is less than or equal to a current rating of the hard disk array, wherein the current current is updated according to an operating state of the plurality of hard disks; and a sum of the starting current and a current current of the hard disk array is less than or equal to a rated current of the hard disk array When the hard disk is booted.

Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of a method for controlling power-on of a hard disk in a hard disk array according to the present disclosure.

In step 110, multiple hard disks of the hard disk array are sequentially started.

The hard disk array is composed of a plurality of hard disks, and the hard disks in the hard disk array may be the same type of hard disks or different types of hard disks. In this embodiment, the hard disk array is exemplified by four hard disks. Referring to FIG. 2, the four hard disks are a hard disk of type seagate2000, two hard disks of type WD250, and one hard disk of type hitachi500. The rated current of the hard disk array is 10A, and the working parameters of the four hard disks are as follows:

硬盘型号Hard disk model	启动电流Starting current	启动时长Startup time	工作电流Working current
WD250WD250	2A2A	4s4s	1A1A
hitachi500Hitachi500	4A4A	7s7s	2A2A
seagate2000Seagate2000	7A7A	10s10s	3A3A

It can be understood that the hard disk array can also be composed of two, three, five, six, seven, and the like, and the number of hard disks can be determined according to actual needs. The hard disk model may be the above model or other models than the above models. When powering on the hard disk of the hard disk array, first determine whether there is an unstarted hard disk in the hard disk array. After determining that the hard disk is not started in the hard disk array, start the multiple hard disks in the order of the hard disk in the hard disk array. . Taking the above hard disk array as an example, in the hard disk array, the boot order of the plurality of hard disks is the first boot of the hard disk model seagate2000, the second hard disk of the first model WD250, and the second model is WD250. The third boot of the hard disk is the fourth boot of the hard disk of the hitachi 500. When the hard disk of the hard disk array is powered on, the hard disk is sequentially started in the above order.

In step 120, the startup current of the hard disk is obtained before starting each hard disk, and it is determined whether the sum of the startup current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array, where The current current is updated according to the operating states of the plurality of hard disks.

When powering on the hard disk of the hard disk array, first start the hard disk of the model seagate2000, and obtain the starting current of the hard disk before starting the hard disk. The starting current can be obtained by looking up a table. In the system of the hard disk array, there is a table of starting time, starting current and working current indexed by the hard disk model. It can be known from the table that the starting current of the hard disk is 7A. After obtaining the startup current of the hard disk, determining whether the sum of the startup current and the current current of the hard disk array is less than or equal to The rated current of the hard disk array. Since the hard disk of the model seagate2000 is the first boot hard disk of the hard disk array, the current current of the hard disk array before the hard disk of the model seagate2000 has not been started is 0A. However, the current current of the hard disk array is not fixed, and the current current of the hard disk array is updated according to the operating state of the multiple hard disks, and the current current is updated when the hard disk is started. When the hard disk startup is completed, the current current is also updated, that is, when the system detects that a hard disk is started or a hard disk is started, a current current update command is triggered, and then the current current is once performed according to the command. Update.

In step 130, the hard disk is started when the sum of the startup current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array.

The hard disk is activated when it is determined that the sum of the startup current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array. For example, before the first hard disk is started, the sum of the starting current and the current current of the hard disk array is 7A+0A, that is, 7A, and the current value is less than the rated current value of the hard disk array by 10A, and the hard disk is started, and Set the hard drive to be started. After the hard disk is started, the current current is updated once, and then steps 110 to 130 are repeated until all the hard disks in the hard disk array are started, and the hard disk is powered on. During power-on operation of the hard disk array, if it is determined that the sum of the startup current and the current current of the hard disk array is greater than the rated current of the hard disk array before starting the hard disk, wait for a period of time until the determination is performed. The hard disk is started when the sum of the startup current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array, and the hard disk is set to be activated. During the waiting time, it may be determined in real time or periodically whether the sum of the starting current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array, and may also update the current current of the hard disk array each time. After determining whether the sum of the starting current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array, when it is determined that the sum of the currents is less than or equal to the rated current, immediately start the Hard drive and set the hard drive to be started.

In the embodiment, when the hard disk in the hard disk array is powered on, the current current of the hard disk array is updated according to the running state of the hard disk array of the hard disk array, and the current detecting module is not required to be acquired, thereby saving hardware cost and simultaneously Starting a plurality of hard disks of the hard disk array, and determining whether a sum of a boot current of the hard disk and a current current of the hard disk array is less than or equal to a rated current of the hard disk array of the hard disk array before starting each hard disk, where the starting current and the current are The hard disk array is activated when the sum of current currents of the hard disk array is less than or equal to the rated current of the hard disk array, and the hard disk array can be solved. When the hard disk is powered on at the same time, the power output is over-current, shut down, and other abnormal conditions, which reduces the maximum power consumption of the system and reduces the impact on the power supply.

When each hard disk in the hard disk array is started, the current current of the hard disk array is updated once. The update process is: increasing the current current of the hard disk array. The starting current of the hard disk, that is, the current current is equal to the sum of the current current of the previous time and the starting current of the hard disk.

In step 320, when the hard disk startup is completed, the current of the hard disk array is subtracted from the current of the hard disk and the operating current of the hard disk is increased.

When the booting of each hard disk of the hard disk array is completed, the current current of the hard disk array is also updated once, and the updating process is: subtracting the starting current of the hard disk from the current current of the hard disk array and adding the The operating current of the hard disk, that is, the current current is equal to the current current of the previous time minus the starting current of the hard disk plus the operating current of the hard disk. Referring to FIG. 4, the determining whether the hard disk is booted or not includes steps 410 to 420.

In step 410, it is determined whether the started time of the hard disk in the activated state in the hard disk array reaches the startup time.

After the booting, the hard disk in the bootable state of the hard disk array determines whether the booting time of the hard disk is reached in real time or timing. Referring to FIG. 5, the determining whether the boot time of the hard disk in the boot state in the hard disk array reaches the boot time of the hard disk includes

In step 520, it is determined whether the started time of the hard disk reaches the startup time according to the startup time and the started time corresponding to the hard disk, wherein the started time is a time difference between the current time and the startup time.

After the hard disk is started, record the startup time and startup time of the hard disk, and pass a A timer or counter records the started time of the hard disk. In the process of determining whether the boot time of the hard disk reaches the startup time, the startup time and the startup time of the recorded hard disk may be obtained, and determining the hard disk according to the startup time and the startup time of the hard disk. Whether the started time has reached the startup time. Determining that the started time of the hard disk reaches a startup time when the started time is greater than or equal to the startup time; determining that the started time of the hard disk does not reach the startup when the started time is less than the startup time duration. The started time is a time recorded by a timer or a counter, and the time value is a time difference between the current time and the start time.

In step 420, when the boot time of the hard disk in the boot state reaches the boot time, it is determined that the hard disk boot is completed.

When it is determined that the started time of the hard disk in the startup state reaches the startup time, it is determined that the hard disk startup is completed. When the set timer or counter value reaches the set startup time, a startup completion command is triggered, and after receiving the startup completion command, the system determines that the hard disk startup is completed, and if the system does not receive the startup completion command, Indicates that the hard disk is still in the startup state, and no startup is completed.

In this embodiment, when the current current of the hard disk array is updated, the current current of the hard disk array is updated after the hard disk is started and the hard disk startup is completed, and the current current is not updated in real time or periodically, so that the current is The current current update is very simple and not cumbersome.

After the model of the hard disk is read, the working parameters of the hard disk are obtained according to the model, wherein the working parameters include a starting current, an operating current, and a startup time. For example, when the model of the hard disk is seagate2000, the model is indexed, and a table of starting time, starting current and working current with the hard disk model as the main key is found, and the hard disk can be obtained according to the table. Working parameters. When the hard disk model is read as WD250, the model is also indexed to find a boot time, starting current and working power with the hard disk model as the main key.

The startup module 10 activates the hard disk when it is determined that the sum of the startup current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array. For example, before the first hard disk is started, the sum of the starting current and the current current of the hard disk array is 7A+0A, that is, 7A, and the current value is less than the rated current value of the hard disk array by 10A, and the hard disk is started, and Set the hard drive to be started. After the hard disk is started, the current current is updated once, and then the startup process is repeated, and the process and the judgment process are determined until all the hard disks in the hard disk array are started, and the hard disk is powered on. During the power-on operation of the hard disk of the array, if it is determined that the sum of the startup current and the current current of the hard disk array is greater than the rated current of the hard disk array before starting the hard disk, waiting for a period of time until determining that the When the sum of the startup current and the current current of the hard disk array is less than or equal to the rated current of the hard disk array, the startup module 10 starts the hard disk and sets the hard disk to be activated.

After each hard disk in the hard disk array is started, the determining module 30 updates the current current of the hard disk array once, and the update process is: current to the hard disk array. The current increases the starting current of the hard disk, that is, the current current is equal to the sum of the current current of the previous time and the starting current of the hard disk; when each hard disk of the hard disk array is booted, the determining module 30 also needs Updating the current current of the hard disk array by updating the current of the hard disk array by the current of the hard disk and increasing the operating current of the hard disk, that is, the current current is equal to the current current time.
