a method for optimizing the input and output performance of a mechanical hard disk specifically comprises the following steps:

and step 109, if the input/output data is the write input/output data, invalidating the current write input/output data of the auxiliary cache partition and the main cache partition, and updating the write input/output data of the main cache partition through the input/output optimal channel node.
By the scheme, mapping is established between the solid state disk and the mechanical hard disk, the read IO performance of the mechanical hard disk is accelerated, main and auxiliary cache partitions are established through the solid state disk, the data hit by the cache is updated in the main cache partition through invalidating the IO of the auxiliary cache partition, so that the IO hit by the main and auxiliary partitions can be different, the IO performance of the mechanical hard disk is optimized, and the resources of a storage system are saved.
In some embodiments, the method further comprises:
and if the input and output data is not hit by the cache partition, reading and writing the input and output data from the accelerated volume.
In some embodiments, the method further comprises:
writing the updated write input/output data of the main cache partition to the accelerated volume.
In some embodiments, updating write input output data of the main cache partition by the input output optimal channel node includes:
and responding to the completion of the current write input output data failure of the auxiliary cache partition and the main cache partition, and writing new write input output data into the main cache partition through the input output optimal channel node.
In some embodiments, the method further comprises: if the input/output data is the read input/output data, the data is read from the cache partition and returned to the host side.
In some embodiments, writing the updated write input output data of the primary cache partition to the accelerated volume includes:
writing the updated write input/output data of the main cache partition to a rear-end disk of the accelerated volume.
Embodiments of the present invention will be described below by way of specific examples.
And creating a cache partition by using the solid state disk, wherein the cache partition is divided into a main cache partition and an auxiliary cache partition, and creating an accelerated volume by using the mechanical hard disk. The cache partition is connected to a plurality of storage devices, for example, a dual-control storage device, where the dual-control storage device is connected to the cache partition, and designates a storage device connected to the main cache partition as an IO optimal channel node, and if the storage device is called a candidate, another storage device is connected to the auxiliary cache partition. The configuration management end of the server only stores node information of the main cache partition, the main cache partition and the auxiliary cache partition are distinguished only through the cache partition ID, configuration writing IO is only carried out from the perspective, when IO is processed, the cache partition is assumed to be accelerated by mapping due to multipath strategy, and the cache partition is assumed to hit a lot of IO after a period of time. The host end writes an IO, and the position where the IO is written to the back-end disk is inserted into the cache partition by the cache partition through a pre-reading algorithm. The IO hit by the primary and secondary cache partitions is exactly the same at this time. Now, as the IO is written, the data of the disk at the back end of the accelerated volume needs to be updated and the IO hit in the cache partition needs to be updated. At the moment, the auxiliary cache partition is informed of losing the hit IO, the main cache partition is also informed of losing the hit IO, and after the auxiliary cache partition is finished, the main cache partition is informed of the main cache partition, and the main cache partition writes the new write IO into the cache partition and writes the new write IO into the rear-end disk. Thus, the IO hit by the main cache partition and the secondary cache partition respectively connected with the two storage devices are different. When the read IO comes down, if the read IO is from the auxiliary cache partition connected with the opposite-end storage device, and the auxiliary cache partition does not have hit IO at the moment, the data is directly read from the rear-end disk of the accelerated volume, and then the data is fed back to the main sentence after being inserted into the cache partition; if the read is from the reference, the hit IO on the reference can be directly fed back to the host without reading from the back-end disk.
By the scheme, the IO reading performance of the mechanical hard disk is accelerated, the resources of a storage system are saved, and the IO performance of the HDD is optimized.

if the input/output data is the write input/output data, invalidating the current write input/output data of the auxiliary cache partition and the main cache partition, and updating the write input/output data of the main cache partition through the input/output optimal channel node;
writing the updated write input/output data of the main cache partition to the accelerated volume.
2. The method as recited in claim 1, further comprising:
and if the input and output data is not hit by the cache partition, reading and writing the input and output data from the accelerated volume.
3. The method of claim 1, wherein updating write input output data of a main cache partition by the input output optimal channel node comprises:
and responding to the completion of the current write input output data failure of the auxiliary cache partition and the main cache partition, and writing new write input output data into the main cache partition through the input output optimal channel node.
4. The method as recited in claim 1, further comprising: if the input/output data is the read input/output data, the data is read from the cache partition and returned to the host side.
5. The method of claim 1, wherein writing the updated write input output data of the primary cache partition to the accelerated volume comprises:
writing the updated write input/output data of the main cache partition to a rear-end disk of the accelerated volume.
6. A system for optimizing mechanical hard disk input/output performance, comprising:
the system comprises a creation module, a storage module and a storage module, wherein the creation module is configured to create a cache partition based on a solid state disk and an accelerated volume based on a mechanical hard disk, and create a mapping between the cache partition and the accelerated volume, wherein the cache partition comprises a main cache partition and an auxiliary cache partition;
the acquisition module is configured to acquire a plurality of storage devices connected with the main cache partition and the auxiliary cache partition, and takes the storage devices connected to the main cache partition as input-output optimal channel nodes;
the first judging module is configured to respond to receiving input and output data sent by a host side and judge whether the input and output data is hit by a cache partition or not;
the second judging module is configured to judge whether the input and output data is read input and output data or write input and output data if the input and output data is hit by a cache partition;
and the invalidation module is configured to invalidate the current write input output data of the auxiliary cache partition and the main cache partition if the input output data is the write input output data, and update the write input output data of the main cache partition through the input output optimal channel node.
7. The system of claim 6, further comprising a read-write module configured to read input-output data from the accelerated volume if the input-output data is not hit by the cache partition.
8. A computer device, comprising:
at least one processor; and
a memory storing a computer program executable on the processor, wherein the processor performs the steps of the method of any one of claims 1-5 when the program is executed.
9. A computer readable storage medium storing a computer program, characterized in that the computer program when executed by a processor performs the steps of the method according to any one of claims 1-5.
