A kind of pcie card form hard disk expansion device and electronic equipment

Abstract

The invention provides a hard disk expansion device and electronic equipment in the form of a PCIE card, belonging to the technical field of computer servers, solving the problem that adding a PCIE SSD in the prior art cannot realize unified management of hard disks, and the cost of adding machines is high and flexible. The technical problem of poor performance and inability to achieve dynamic configuration. Including a motherboard and a backplane in the form of a PCIE card; the motherboard includes a PCIE slot, a first multiplexer, a BMC and a CPU; the two input ends of the first multiplexer are respectively connected to the backplane I2C chain of the BMC The output end of the first multiplexer is connected to the PCIE slot, and the PCIE link of the CPU is connected to the PCIE slot; the backplane in the form of a PCIE card includes CPLD, hard disk connector, in-position signal end and Gold finger matching the PCIE slot. The invention uses the golden finger to connect all the signals of the general backplane and the mainboard to the mainboard through the golden finger, and the PCIE card has good flexibility and can realize the flexible expansion of the hard disk.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a hard disk expansion device in the form of a PCIE card and an electronic device. Background technique [0002] With the development of information technology, the current server configuration is more and more abundant, which needs to meet various needs. Due to the increasing data volume of the current server, the number of hard disks required increases accordingly. And for the servers under different applications in the computer room, some servers will overflow and some will be insufficient in storage capacity. In the case of insufficient storage capacity, when the internal backplane of the chassis cannot expand the hard disk, the number of servers can only be increased to make up, and the cost is high. Therefore, it is very necessary to flexibly increase the number of hard disks in the server. [0003] In the current server, the signal connection between the backpla...
