The existing data splicing method makes full use of the physical storage space and has a high space utilization rate, but its implementation is complicated, and since the recovery of the data will form scattered fragments of different sizes, it is necessary to defragment the space to improve the utilization efficiency, so, Brings additional overhead to the storage system
Relatively speaking, the data partitioning method is easy to allocate and recover, and the system overhead is low, but each data occupies a partition block independently. Even if the size of the data is much smaller than the block size, the remaining space of the block cannot Reuse, at the same time, the number of partitions should not be too large, and it is impossible to create a partition for each data size. If this is the case, there will be many partitions, and the space allocated to each partition will be very small, and the data falling on each partition The amount is not certain, which will cause frequent repartitioning of space between partitions

The invention provides a data storage space distribution method and device, and electronic equipment. The data storage space is divided into at least two storage areas, each storage area is provided with a plurality of strip blocks used for storing data with specified sizes, the strip blocks corresponding to different storage areas are different in capacity, and the method comprises: obtaining thedata size of the stored data in each strip block; Respectively comparing the data volume with each preset gear, and counting the number of data falling into each preset gear; According to the numberof the occupied blocks in each storage area and the statistical parameters, determining whether to create a new storage area and corresponding blocks, Wherein the statistical parameters comprise the number of the counted data falling into the preset gear and / or the statistical value describing the statistical distribution rule of the number. According to the provided distribution method of the data storage space, waste of the storage space can be reduced, reasonable partition configuration is achieved, and the utilization rate of the storage space is increased.
Description
technical field [0001] This description relates to the technical field of data storage, and in particular to a data storage space allocation method, device and electronic equipment. Background technique [0002] Based on the high storage cost of the storage system, and the size of the stored data is relatively discrete, how to allocate storage space to store data of different sizes has always been a problem in data storage. Common data preservation methods include: data splicing method and data partitioning method. Among them, the data splicing method splices multiple data together to form a large physical block, and then saves it; the data partitioning method divides the actual physical storage space of the storage device into multiple partitions, and the block size of each partition is different. Same. The existing data splicing method makes full use of the physical storage space and has a high space utilization rate, but its implementation is complicated, and since the ...
