Abstract

The embodiment of the invention discloses a data processing method and device, relates to the field of information technology, and solves the problem that data is easily lost when the thin pool is full. The specific solution is: judge whether the data area of ​​the thin pool is full, and if the data area is full, store the data in the cache in the page reserved area in the form of pages. The invention is used for data processing.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a data processing method and device. Background technique [0002] Thin Provisioning technology (Thin Provisioning, TP) is a virtualized storage technology evolved from the traditional space allocation method. It gathers all physical storage space into a thin pool for unified management. The thin pool is the bottom layer of the thin provisioning system. The logical storage space mapped from the physical storage space. A thin logical unit number (Logic UnitNumber, LUN) is a storage unit of a thin pool, and physical storage space can be obtained from the thin pool as required. [0003] When the thin pool is full, there may still be data in the cache that cannot be written into the thin pool, and the system can only keep this part of the data in the cache, which will occupy a large amount of cache, affect other services, and stay in the cache The data is easily lost, ...
