Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0010] A preferred embodiment is given below:

[0011] A low-cost JBOD is composed of a chassis 9, a controller 7, a SAS RIAD card 8, a built-in SAS RAID card external device 6, and a hard disk. The RAID card external device 6 is connected. Built-in SAS RAID card external device 6 is composed of 8087SAS internal interface 1, data line 2 and 8088SAS external interface 3, 8087SAS internal interface 1 and 8088SAS external interface 3 are connected through data line 2. The 8088SAS external interface 3 of the built-in SAS RAID card external device 6 is provided with an IO plate 4 . The corresponding relationship between the 8087SAS internal interface 1 and the 8088SAS external interface 3 pin angles of the built-in SAS RAID card external device 6 is: A2-B2; A3-B3; A5-B5; A6-B6; A13-B8; A14-B9; A16-...

Abstract

The invention relates the field of computer fittings, and specifically provides a low-cost JBOD, comprising a cabinet, a controller, a SAS RIAD card, a built-in SAS RIAD card external connection device and a hard disc, the hard disc connects with the controller by the SAS RAID card, the SAS RAID card and the SAS RAID card external connection device are connected. Compared with prior art, the low-cost JBOD has the characteristics of simple structure, and convenient usage, etc.

Description

technical field [0001] The invention relates to the field of computer accessories and specifically provides a low-cost JBOD. Background technique [0002] In the prior art, the number of hard disks supported by general servers is limited. In order to increase the number of disks, SAS RAID cards are mostly used, but some built-in SAS RAID cards have no external interface, and SAS RAID cards need to be used in conjunction with computer hardware systems, and cannot pass through RAID cards. Connect directly to the disk expansion cabinet (JBOD). The data connection with the disk expansion cabinet can only be realized by replacing the RAID card, which is complicated to operate and wastes resources. However, general-purpose disk expansion cabinets often have high costs and a long development cycle. Contents of the invention [0003] The present invention aims at the disadvantages of the above-mentioned prior art, and provides a JBOD with simple structure and low cost, so that w...
