JBOD mainboard and storage system

Abstract

The invention discloses a JBOD mainboard and a storage system. The JBOD mainboard comprises an independent expander chip, uplink ports and downlink ports, wherein the uplink ports and the downlink ports are connected with the independent expander chip; the number of the uplink ports and the number of the downlink ports are both at least three, and connected domain isolation is carried out betweendifferent uplink ports; a connected domain between different downlink ports is configured; the uplink ports are connected with a host through an SAS cable; and the downlink ports are connected with the lower-level JBOD mainboard through an SAS cable so as to realize expansion of the JBOD mainboard. According to the JBOD mainboard, uplink and downlink ports are expanded, and the design cost, powerconsumption, complexity, IO depth and time delay in the use process of the JBOD mainboard are reduced, and the problems of difficult heat dissipation and the like are avoided. Correspondingly, the storage system disclosed by the invention also has the above technical effects.

Description

technical field [0001] The present application relates to the technical field of storage, in particular to a JBOD motherboard and a storage system. Background technique [0002] In the prior art, in order to improve the expansion capability of the JBOD main board, the JBOD main board is usually connected to more lower-level JBOD main boards, which will increase the design cost, power consumption and complexity of the JBOD main board, and will also increase the IO depth and prolong the use of the JBOD main board. delay in the process. [0003] Therefore, how to reduce the cost, power consumption and complexity of the JBOD main board is a problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the purpose of the present application is to provide a JBOD mainboard and a storage system, so as to reduce the cost, power consumption and complexity of the JBOD mainboard. The specific plan is as follows: [0005] In the first aspect, ...
