Problems solved by technology

[0021] 1. When a large number of data streams are written concurrently, the monitoring storage system is under great pressure to simultaneously process and analyze the data destination address, and the average IO response time increases significantly
[0022]2. When a large number of data streams are written concurrently, the cache unit will request to write data to the array at the same time after it is full, resulting in irregular disk writing Seek phenomenon, which increases the refresh time, resulting in a decline in the performance of storage devices
[0023]3. When a large number of data streams are written concurrently, the usage rate of the cache unit is high. When data is written to the storage device in time, the corresponding cache unit will be in a state of waiting for continuous data for a long time, which will affect the use of the cache unit by other normal devices, and the performance of the storage device will decline

Embodiment Construction

[0060] The core idea of ​​the present invention is to divide the written data stream into several batches according to the length of the time slice and process them separately. When the storage device processes one batch of data packets, the other batches of data packets will wait in turn. The arrival of its own time slice, only when the length of its own time slice is reached, the array will be written. Therefore, a large number of concurrent sequential data streams are divided into batches according to time slices, which reduces the concurrent workload of the storage device for judging the continuity of data written into the cache unit, and reduces the average response time of IO; and by combining a large number of concurrent The sequential data flow is divided into batches according to the time slice, which reduces the request to write data to the array after the cache unit is full, so that the disk presents a certain sequence when writing, which is convenient for seeking an...

Abstract

The invention discloses a storage method based on time division multiplex. Storage equipment divides data into at least two batches; the storage equipment sets time slice lengths for the data of each batch according to dividing results; and the storage equipment sequentially receives the data of each batch according to the time slice lengths and processes the data. The invention obviously enhances the utility ratio of a buffer unit by using a time division multiplex technology.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a storage method and device based on time division multiplexing. Background technique [0002] RAID (Redundant Array of Inexpensive Disks, Redundant Array of Disks) is a high-performance, high-reliability storage technology that provides logical storage for application terminals or terminal clusters by combining a series of individual disks in different ways disk. Among them, the advantages of using RAID include: expanding disk capacity, improving disk read and write performance, and data security. [0003] Specifically, RAID technology has been widely used in various occasions of data storage, using RAID technology includes RAID0, RAID1, RAID5, RAID6, RAID10, etc.; wherein, RAID0 does not have redundancy capabilities, and RAID1 is not a complete disk array; and RAID5, RAID6, and RAID10 are composed of multiple disks (for example, no less than 3 disks for RAID5 an...
