Abstract

The invention provides a JBOD (Just Bunch of Disks), which comprises a case, a controller and a disk, wherein the controller and the disk are arranged in the case; and the disk is connected with the controller. The JBOD can at least realize high density.

Description

Technical field [0001] The present invention relates to the technical field of storage devices, in particular to a JBOD. Background technique [0002] In order to quickly expand storage resources and improve resource utilization, it is necessary to separate the disk from the server locally, so disk clusters (JustBunchofDisks, JBOD) were born, which are widely used in traditional disk array backends and new storage computing in the Internet field Decoupling platform. [0003] The existing JBOD solutions are divided into two categories: One is the JBOD used in traditional fields, such as DellMD1400, Quanta M4240H and Quanta M4600H, etc., which are mainly used in the back end of disk arrays, such as EMCVMAX. The other is the JBOD solution adopted by large Internet vendors, represented by Facebook and Microsoft, Internet vendors use JBOD to decouple computing and storage resources. [0004] However, the JBOD in the prior art has the following problems: low density, high cost, difficult...
