Description

Circuit board, server and server network
Technical Field
The present disclosure relates to the field of networks, and more particularly, to a circuit board, a server and a server network.
Background
In a conventional data network, SFP (Small Form-factor pluggable transceiver) 28 and QSFP (Quad Small Form-factor pluggable transceiver) 28 are used as main interfaces of 25G and 50G network cards, and the following table shows the general conditions.
TABLE 1 network card interface situation
Speed of rotation Type of package Number of differential lines
25G SFP28 1
50G QSFP28 2
A BMC (Baseboard management controller) management network generally uses an RJ45 connector to transmit data at a rate of 1000Mbps because the rate requirement is not high.
On a conventional server, at least 2 network cables are required for one server, 1 for 25G or 50G data networks and the other for management network transmission.
This implementation has several disadvantages as follows:
at least two network cables on one node result in a more complicated connection mode.
Typically switches support only optical or electrical ports. The data network is an optical port and the management network is an electrical port, so that one node is connected to 2 switches at the same time.
The OPEN19 specification was initiated by LinkedIn (lingering) by the end of 2016 and is suitable for data centers of any size. The OPEN19 specification redefines the interconnection mode of the nodes and the switches, and the interconnection mode comprises the type of the switch, the type of the cable, the transmission protocol and the type of the connector, which are all customized. Compared with the traditional network connection mode, the following aims are provided:
(1) a maximum of 12 nodes share one network cable, so that the deployment is convenient.
(2) The data network and the management network are external in the node by using the same connector.
(3) The network usage of 10G, 25G and 50G can be simultaneously supported.
