Problems solved by technology

[0006] There are two ways to expand the storage backplane of traditional servers. The first method is to customize the server storage backplane with different numbers of hard disk interfaces according to product requirements. The installation method is as follows: figure 1 As shown, the disadvantage is: in order to meet the requirements of different storage servers for the number of hard disks, it is necessary to customize and develop server storage backplanes, and install server storage backplanes of different models and sizes in the storage server. Take out the original server storage backplane from the server and replace the server storage backplane
The installation method is as follows figure 2 As shown, the disadvantages of this method are: high structure and space requirements, difficult installation in a tight server space, affecting heat dissipation, and due to the use of a large number of cables and high-speed connectors, high cost, complicated installation, and inconvenient replacement

Embodiment 1

[0034] Embodiment 1 of the present invention provides an expandable and combined server storage backplane, including a main card and at least one expansion supplementary card, and three expansion supplementary cards can be cascaded on the main card.

[0035] see image 3 As shown, the main card includes a storage board power supply module, a hard disk storage expansion module, a control module, a power connector, and a high-speed connector. The hard disk storage expansion module is connected to several hard disks, the control module is connected to the hard disk storage expansion module, and the high-speed connection of the main card The connectors are respectively connected with the hard disk storage expansion module, the control module and the expansion supplementary card, and the power connectors of the main card are respectively connected with the storage board power supply module and the expansion supplementary card.

[0036] see Figure 4 As shown, each expansion card i...

Embodiment 2

[0042] On the basis of embodiment 1, see image 3 As shown, the high-speed connector of the main card connects the SAS interface and logic control interface of the hard disk storage expansion module to the expansion supplementary card, so that the hard disk connected to the expansion supplementary card communicates with the hard disk storage expansion module, and controls lighting and electronic switch strobe .

[0043] see image 3 As shown in the figure, the power connector of the main card supplies power to the hard disk connected to the expansion card through the storage board power supply module of the main card.

[0044] see image 3 As shown, the storage board power supply module of the main card includes a power connector and a voltage conversion circuit, the power connector obtains power from the outside, and the voltage conversion circuit adjusts the output voltage, which is used as the power input of the hard disk and the expansion card .

[0045] The hard disk ...

Embodiment 3

[0050] On the basis of embodiment 2, the main card also includes an external SAS interface, a power supply interface and a management interface, wherein the SAS interface of the main card is connected to the SAS controller of the RAID card installed on the server main board, and is used for the server main board through the expansion backplane communicate with the hard drive. One side of the management interface is connected to the main board, and the other side is connected to the hard disk storage expansion module, which is used to control, manage and configure the expansion board. The power interface realizes the power supply function of the hard disk and the backplane chip.

[0051] The embodiment of the present invention adopts an expandable and combined server storage backplane. Through the direct connection combination of the main card + expansion supplementary card, three expansion supplementary cards are cascaded on the main card. Through combination and matching, vari...

Abstract

The invention discloses a scalable combined server storage backplane, which relates to the field of server storage backplane. The backplane includes a master card, at least one expansion attachment card, each expansion attachment card comprises a set of electronic switches, two high-speed connectors, one high-speed connector connecting that main card or the upper expansion attachment card, the other high-speed connector cascading the lower expansion attachment card, two high-speed connectors are connected through electronic switches, each high-speed connector is connected with a hard disk; themaster card switches the control signal to the high-speed connector of the next stage of the extension attachment card by controlling the electronic switch. The invention can connect three expansionattachments at the upper level of the main card, flexibly realizes the function of a multi-disk storage server, shortens the development time, improves the product development speed, reduces the cost,and is simple and convenient to update.

Description

technical field [0001] The invention relates to the field of server storage backplanes, in particular to an expandable and combined server storage backplane. Background technique [0002] A rack server is a high-performance general-purpose computer that, as an important node of the network, stores and processes data or information on the network. With the rapid development of cloud computing, big data, mobile Internet and the Internet of Things, it brings challenges to massive data, diversification and information services, complex data aggregation and interaction capabilities, and, in the "hardware reconstruction + software Driven by the integrated architecture of "Definition + Network Function Virtualization", whether it is an Internet data center, an enterprise-level data center, or a telecom network infrastructure, the demand for servers is increasingly urgent and diverse. [0003] Storage servers are designed for a specific purpose, and therefore configured differently...
