In order to further describe the storage control method shown in FIG. 1 , please refer to FIG. 2 , which shows a flow chart of a storage control method according to another embodiment of the present invention. Taking the application in a hybrid storage system including a mechanical hard disk and a solid state disk as an example, the storage control method may include:

Step 202, the storage system obtains control parameters, the control parameters include: at least one of the type of system business, the temperature value of the mechanical hard disk, the vibration value of the mechanical hard disk, the remaining erasable times of the solid-state hard disk, and the remaining capacity of the solid-state hard disk ;

Among them, the type of system business can be divided into sequential writing and random writing, wherein, sequential writing is the type of system business when the data writing sector of the system business is a continuous sector, and random writing is the data of the system business The type of the system service when the writing sector is a discontinuous sector.

The temperature value and vibration value of the mechanical hard disk can be obtained respectively through the temperature sensor and the vibration sensor built in the storage array. In addition, the storage system can also directly read the temperature information of the mechanical hard disk included in the SMART (Self-Monitoring, Analysis and Reporting Technology) information reported by the mechanical hard disk.

The remaining erasable times of the SSD can be obtained directly from the SMART information reported by the SSD. The remaining capacity of the solid state disk can be directly reported by the solid state disk.

Step 204, the storage system controls the storage operation in the hybrid storage system according to the obtained control parameter.

When the control parameter includes the type of system business, the storage system can detect whether the type of the system business is sequential writing; wherein, the sequential writing is: the type of the system business when the data writing sector of the system business is a continuous sector ; If it is detected that the type of the system service is sequential writing, the storage system controls the service data of the system service to be written into the solid-state hard disk first.

Specifically, in order to give full play to the advantages of fast read and write speeds of solid-state hard disks, the storage system may write data whose business type is sequential writing to the solid-state hard disk first.

When the control parameter includes the temperature value of the mechanical hard disk, the storage system can detect whether the temperature value of the mechanical hard disk exceeds the first temperature threshold; if it detects that the temperature value of the mechanical hard disk exceeds the first temperature threshold, the storage system controls the mechanical hard disk Reduce read and write speeds.

Preferably, after controlling the mechanical hard disk to reduce the read and write speed, the storage system can also detect whether the temperature value of the mechanical hard disk exceeds a second temperature threshold, and the second temperature threshold is greater than the first temperature threshold; if the temperature value of the mechanical hard disk is detected If the second temperature threshold is exceeded, the storage system controls the mechanical hard disk to stop running.

More preferably, after controlling the mechanical hard disk to stop running, the storage system can also detect whether the temperature value of the mechanical hard disk is lower than a third temperature threshold, and the third temperature threshold is equal to or smaller than the second temperature threshold; When the temperature value of the hard disk is lower than the third temperature threshold, the storage system controls the mechanical hard disk to restart operation.

Specifically, different types of mechanical hard disks may have different temperature ranges for normal use. The storage system can set a first temperature threshold in advance according to the operating temperature range of the currently used mechanical hard disk. In order to prevent the mechanical hard When the temperature threshold is reached, the read/write speed of the mechanical hard disk will be reduced. When it is detected that the temperature of the mechanical hard disk exceeds the preset second temperature threshold, which is higher than the first temperature threshold, the storage system can stop the operation of the mechanical hard disk, and transfer the read and write operations of the current system business to the solid-state hard disk for operation . Further, after the mechanical hard disk stops running, if it is detected that the temperature of the mechanical hard disk drops to the preset third temperature threshold (the third temperature threshold can be set to be smaller than the second temperature threshold or equal to the second temperature threshold ), you can restart the mechanical hard disk.

When the control parameters include the vibration value of the mechanical hard disk, the storage system can detect whether the vibration value of the mechanical hard disk exceeds the first vibration threshold; if it detects that the vibration value of the mechanical hard disk exceeds the first vibration threshold, the storage system controls the mechanical The hard disk slows down the read and write speed.

Preferably, after controlling the mechanical hard disk to reduce the read/write speed, the storage system can also detect whether the vibration value of the mechanical hard disk exceeds a second vibration threshold, and the second vibration threshold is greater than the first vibration threshold; if the mechanical hard disk is detected If the vibration value exceeds the second vibration threshold, the storage system controls the mechanical hard disk to stop running.

More preferably, after controlling the mechanical hard disk to stop running, the storage system can also detect whether the vibration value of the mechanical hard disk is lower than a third vibration threshold, and the third vibration threshold is equal to or smaller than the second vibration threshold; When the vibration value of the hard disk is lower than the third vibration threshold, the storage system controls the mechanical hard disk to restart operation.

Specifically, the storage system can set a first vibration threshold in advance according to the vibration value range of the mechanical hard disk in normal use. In order to prevent the mechanical hard When the first vibration threshold is exceeded, the read/write speed of the mechanical hard disk is reduced. When it is detected that the vibration value of the mechanical hard disk exceeds the preset second vibration threshold higher than the first vibration threshold, the storage system can stop the operation of the mechanical hard disk and transfer the read and write operations of the current system business to the solid state disk run in. Further, after the mechanical hard disk stops running, if it is detected that the vibration value of the mechanical hard disk drops to the preset third vibration threshold (the third vibration threshold can be set to be smaller than the second vibration threshold or equal to the second vibration threshold equal), you can restart the mechanical hard disk.

When the control parameters include the remaining erasable times of the solid-state hard disk, the storage system detects whether the remaining erasable times of the solid-state hard disk is less than a predetermined erasable threshold; if it is detected that the remaining erasable times of the solid-state hard disk is less than the predetermined threshold, the storage system controls the SSD to stop erasing and writing operations.

Specifically, assuming that the preset erasing threshold is 1000 times, when the storage system detects that the remaining erasable times of the solid-state hard disk is less than 1000 times, in order to prevent the service life of the solid-state hard disk from reaching the limit and reduce the read-write reliability of the solid-state hard disk In this case, the storage system can stop the erasing and writing operation of the solid-state hard disk, and thereafter no longer perform the erasing and writing operation on the solid-state hard disk.

When the control parameter includes the remaining capacity of the solid-state hard disk, the storage system detects whether the remaining capacity of the solid-state hard disk is less than the predetermined capacity threshold; The data with the least amount of access and the least number of historical accesses is moved to the mechanical hard disk.

Assuming that the predetermined capacity threshold is one-tenth of the total capacity of the solid-state drive, when the storage system detects that the remaining capacity of the solid-state drive is less than one-tenth of its total capacity, in order to prevent the solid-state drive from being full and affecting the system Performance, the storage system can move the predetermined amount of data that is not currently accessed and has been accessed the least number of times in the solid-state hard disk to the mechanical hard disk, so as to make room for subsequent read and write operations on the solid-state hard disk.

It should be noted that, in some embodiments, the control parameters acquired by the storage system must include the type of system business, and optionally, may also include the temperature value of the mechanical hard disk, the vibration value of the mechanical hard disk, and the remaining rewritable At least one of the number of times and the remaining capacity of the solid state disk.

In other embodiments, the control parameters acquired by the storage system must include the remaining erasable times of the solid-state hard disk. Optionally, it may also include the type of system business, the temperature value of the mechanical hard disk, the vibration value of the mechanical hard disk, and the solid-state hard disk. At least one of the remaining capacities of .

In some other embodiments, the control parameters obtained by the storage system must include the remaining capacity of the solid-state hard disk, and optionally, may also include the type of system services, the temperature value of the mechanical hard disk, the vibration value of the mechanical hard disk, and the remaining capacity of the solid-state hard disk. at least one of erasing times.

To sum up, it can be seen that the control parameters may necessarily include the type of system business, the temperature value of the mechanical hard disk, the vibration value of the mechanical hard disk, the remaining rewritable times of the solid-state hard disk, and the remaining capacity of the solid-state hard disk. Part of the control parameters , optionally including other control parameters among the five parameters.

At least one control parameter; when the type of system business is sequential writing, the control business data is written to the solid-state hard disk first, so as to fully utilize the advantages of fast read and write speed of the solid-state hard disk; when the temperature value of the mechanical hard disk is higher than the first When the first temperature threshold is reached, the mechanical hard disk is controlled to reduce the operating speed. When the temperature value of the mechanical hard disk is higher than the second temperature threshold, the mechanical hard disk is controlled to stop running. When the temperature value of the mechanical hard disk is lower than the third temperature threshold, the mechanical hard disk is controlled to restart. , which solves the problem of decreased read and write stability in the prior art when the temperature of the mechanical hard disk is too high, and achieves the purpose of improving the overall performance of the system; when the vibration value of the mechanical hard disk is higher than the first vibration threshold, control the mechanical hard disk to reduce the operating speed , when the vibration value of the mechanical hard disk is higher than the second vibration threshold, the mechanical hard disk is controlled to stop running, and when the vibration value of the mechanical hard disk is lower than the third vibration threshold, the mechanical hard disk is controlled to restart, which solves the problem of excessive vibration of the mechanical hard disk in the prior art When it is intense, the problem of reading and writing stability declines to achieve the purpose of improving the overall performance of the system; when the remaining erasable times of the solid-state hard disk is lower than the predetermined erasing threshold, the erasing and writing operation of the solid-state hard disk is stopped, which solves the problem in the prior art. When the erasing and writing life of the solid-state hard disk is exhausted, the stability of reading and writing is reduced to achieve the purpose of improving the overall performance of the system; The least amount of data is moved to the mechanical hard disk, so that when the capacity of the solid-state hard disk in the prior art is insufficient, the advantages of fast reading and writing speed of the solid-state hard disk cannot be brought into play, and the purpose of improving the overall performance of the system is achieved.
