Data storage management method and system based on storage equipment

Abstract

The invention discloses a data storage management method and system based on storage equipment; the method comprises the following steps: setting a plurality of data storage channels respectively having an independent storage medium zone; setting a data storage zone and a data buffer zone in the storage medium zone; distributing the plurality of data storage channels into a plurality of data interactive buffer groups; doing read-write operations for each data storage channel in a polling mode; when one data storage channel is busy, other data buffer zones of other data storage channels in the data interactive buffer group can serve as data buffer memory of the data storage channel. The data buffer zones are arranged in the storage medium as buffer memory; other storage channels in the same group serve as the data buffer zone, thus effectively solving the problems that one busy storage channel will cause whole storage equipment blocking, greatly reducing buffer memory capacity in the storage equipment, and reducing chip area and cost.

Description

technical field [0001] The invention belongs to the field of storage control, in particular to a data storage management method and system based on a storage device. Background technique [0002] see figure 1 , which is a schematic diagram of the storage management principle of the storage device in the prior art. The storage management structure of the storage device in the prior art generally includes a controller, a data cache, and multiple storage channels. Each storage channel is provided with a storage channel drive module and a storage medium connected. In the prior art, the storage medium is only used for data storage. The controller completes the data reading and writing of the storage medium of each storage channel by controlling the storage channel drive module. The controller usually uses serial polling to separately The storage channel reads and writes data. Once a storage channel is in the "busy" state, it needs to wait for the storage channel to return to th...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to allocate a cache for each storage channel to temporarily store the data allocated to the channel when the channel is "busy", which greatly increases the required cache capacity and significantly increases the area and cost of the main control chip;

[0005] 2. When the storage channel is in the "busy" state, the data cache operation is completed by the controller, which increases the overhead of the controller and affects the storage speed and efficiency
