Problems solved by technology

However, there is serious performance degradation inside the SAS topology, and the performance of each level of storage medium is about 5% lower than that of the upper level.
This leads to unbalanced performance of the storage medium, and the storage array built on this basis cannot exert the best performance.

Embodiment Construction

[0014] The core idea of ​​the present invention is to provide a JBOD storage system, which enables all internal storage media to share bandwidth equally, improves storage reliability, and avoids performance attenuation of some storage media.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] The first JBOD storage system provided by the embodiment of this application is as follows: figure 1 said, figure 1 It is a schematic diagram of the first JBOD storage system provided by the embodiment of this ap...

Abstract

The invention discloses a JBOD storage system. The JBOD storage system comprises a first-level SAS Expander, the first-level SAS Expander is provided with an expansion port for inward expansion, the expansion port is connected with at least two second-level SAS Expanders in parallel, and each second-level SAS Expander is connected with a storage part. By means of the JBOD storage system, all storage media in inside space can equally share bandwidth, storage reliability is improved, and performance decay of part of the storage media is reduced.

Description

technical field [0001] The invention belongs to the technical field of data storage, in particular to a JBOD storage system. Background technique [0002] With the needs of business development, there is a further demand for high-density JBOD in the storage field. The general 16-bay JBOD and 24-bay JBOD cannot meet the needs of some users, so 60-bay JBOD, 92-bay JBOD or JBOD with more bays came into being. [0003] The SAS (Serial Attached SCSI / Serial SCSI technology, which is a disk connection technology) topology inside the traditional high-density storage JBOD adopts a serial method. Although the design is simple, it can also support multi-bay expansion. However, there is serious performance degradation inside the SAS topology, and the performance of the storage medium at each level is about 5% lower than that of the storage medium at the previous level. This leads to unbalanced performance of the storage medium, and the storage array built on this basis cannot exert t...
