Embodiment Construction

[0058] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are only part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0059] See figure 1 This figure shows a scenario where a distributed data deduplication storage system 10 according to the present application is applied to IoT devices in a data center, and the facility architecture of the storage system 10. The storage system 10 generally includes several storage units, and all data entering and leaving the storage system 10 passes through the host 50. The storage unit can be, but is not limited to, a hard disk, a solid state drive, a magnetic tape, or a disk array. The number of st...

Abstract

The invention discloses a distributed repeated data deletion and storage system and a distributed repeated data deletion method thereof, which can be applied to a data center of Internet of Things equipment. The system comprises a plurality of storage units, wherein each storage unit comprises: a plurality of positions for storage; a control unit which is used for controlling the operation of thestorage units; and a distributed repeated data deletion module to provide or update the deterministic function to the control unit and an edge component, and perform each step of the method in the control unit and / or the edge component. According to the method provided by the invention, the repeated data deletion is no longer executed by a storage system (a control unit), but the whole process canbe realized through the storage system and the edge component connected with the storage system. Load of the storage system may thus be reduced.

Description

Technical field [0001] This application relates to the field of Internet of Things equipment, and in particular to a method and storage system for distributed deduplication. Background technique [0002] The data center stores a large amount of data for access. Over time, the same data may be packaged in different formats. For example, if a statistical graph is embedded in an EXCEL file or a WORD file, it occupies the storage space of the same data, thus wasting storage space. On the other hand, for continuous data input from a single source, repeated data will also reduce the performance of the data center. This is often seen in streaming update surveillance videos, which contain multiple consecutive frames, one or more corners of which remain unchanged. This is not only another waste of storage space, but also a bottleneck for data transmission in a limited bandwidth network environment. [0003] In order to solve the above problems, the prior art provides many data deduplicat...
