Detailed Description

The invention is further described below with reference to the following figures and specific examples.

The present invention is specifically described with reference to fig. 1-2:

firstly, the cloud mobile phone needs to perform partition planning on local flash storage of an operated hardware platform, and a section of available partition space is preset for a subsequent method.

The cloud mobile phone mounts the large-capacity block storage device provided by cluster storage in a network mode, and carries out formatting operation on the block storage device for combined use of the devices.

A partition preset in local flash storage is combined with block storage equipment mounted on an android system in a network mode to form combined equipment, and the combined equipment is used for storing user data of the android system.

The storage of the subsequent user data is firstly issued to the local flash storage of the combination device, at this moment, the local flash storage partition is equivalent to the cache partition of the combination device, and after the data is issued to the local flash storage, asynchronous I/O (input/output) mode synchronization is carried out on the large-capacity storage device mounted in a network mode by matching with a direct-write or write-back cache strategy, so that the rapid storage operation of the data is realized, and the data writing performance is improved.

When a user application needs to read some data, the data is retrieved or searched in the cache partition at this time, and the data request of the app can be quickly responded after the data is searched, so that the quick reading operation of the data is realized, and the data reading performance is improved.

After the user logs in the application app, the data directory corresponding to the user app program points to the combined storage device, and the storage device is formed by combining the local flash and the network block storage device, so that the flexible expandability is achieved, and the performance of the storage device is almost the same as that of the entity mobile phone.

By adjusting or modifying the I/O storage strategy of the device, the harsh requirements of the application app on storage under different use requirements and scenes of a user can be effectively and flexibly met.

Asynchronous I/O refers to a synchronization strategy of data, firstly, the data in the scheme can be down-brushed to a cache partition, and when the data storage of the cache partition reaches a preset threshold value, the triggering data is down-brushed from the cache partition to a large-capacity storage device mounted in a network mode. The process of writing data to the cache partition does not occur simultaneously with the process of writing data to the network mount device, and is referred to herein as asynchronous I/O.

The strategy is that the data synchronization operation can be triggered when the size of the file stored in the flash partition reaches 30% -50% of the size of the partition, so that the problem that the size of the data exceeds the size of the flash partition is solved.

The speed of data brushing to local flash storage is obviously higher than the speed of data brushing from flash to network storage equipment, and at this time, if data congestion does occur in continuous large I/O (input/output) issuing, the system will drop the speed and the speed is recovered to the scene without flash. The special scene needs to be additionally optimized for an actual case, for example, a cache flash partition with a larger capacity is provided for the scene, and meanwhile, the back-end storage can be optimized, and a similar high-capacity cache is added for the back-end storage, so that the cache mode cannot solve all problems, and only the adaptation evaluation can be performed for a specific use scene.

The asynchronous I/O mainly aims at reducing the issuing times of I/O and converting random I/O requests into sequential I/O requests, the flash has the advantages of high randomness, high concurrency, high bandwidth and high cost, the network mounted large-capacity equipment has the advantages of large storage capacity, high processing bandwidth during sequential I/O storage and low cost, and different advantages of physical storage media are fully utilized and combined.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
