Server device

Technical Field

The invention relates to the technical field of servers, in particular to a server.

Background

Currently, when multiple nodes are provided in a server, various cables, such as signal lines and power lines, are connected between the multiple nodes and each control board. Therefore, once one of the nodes in the server is abnormal or fails, the failed node cannot be directly operated and maintained under the condition that the node is in power-on operation. In general, all nodes need to be powered down and shut down, and then various cables connected with each control board are removed. After the operation and maintenance of the nodes are completed, the cables between the nodes and the control boards are connected.

Therefore, during the power-off maintenance of the node, the customer service is affected, and even if the data is migrated through the standby node, the customer service is further affected due to data loss and data error of the standby node and the maintenance node in the data transmission process, so that the use requirement of the customer cannot be met.

Therefore, the sustainable support of the service can be ensured to the greatest extent, the service migration actions which are increased before the client shuts down all 2 nodes can be reduced as much as possible, even if the client has the design of disaster recovery and data migration, more standby machines are required to be additionally deployed, and the loss and inaccuracy of the data transmission process can exist in the data migration process, so that the client service is influenced, the sensory experience of a user is directly generated, the data loss of the user can be caused under more serious conditions, and based on the fact, the live thermal maintenance of the node module 1 and the PCIE equipment 2 in the server becomes urgent and important.

Embodiments of the present invention are described below with reference to fig. 1 to 15.

According to an embodiment of the present invention, in one aspect, there is provided a server, which includes a chassis 5, a node support 61, a PCIE support 62, and an equipment support 63.

As shown in fig. 8, the male connector of the node module 1 is adapted to be connected with the female connector. That is, for the power supply, the high-speed signal, and the low-speed signal of the node module 1, all can be transmitted through the male connector and the female connector.

Likewise, as shown in fig. 3, a PCIE bracket 62 is provided with female terminals, the PCIE bracket 62 is provided in the mounting cavity, and the PCIE bracket 62 is used for mounting the PCIE device 2.

Cables are arranged in the node support 61, the PCIE support 62 and the equipment support 63, and the female connector, the female terminal and the auxiliary equipment are connected in a communication manner through the cables. Meanwhile, when the installation of each part is completed, the power supply 4 in the device bracket 63 may perform independent power supply and power-off operations on each node module 1 and PCIE device 2 through the cable.

By setting the node support 61 and the PCIE support 62, the embodiment of the present invention may enable the node modules 1 and the PCIE device 2 to perform hot plug operation, that is, if one node module 1 is abnormal or fails when a server is provided with a plurality of node modules 1, operation and maintenance processing may be performed on the failed node module 1 under the condition that the server normally supplies power, without performing power-down shutdown operation on another normal node module 1. Specifically, when the node module 1 is maintained, if the node module 1 needs to be unplugged, the pluggable connectors such as the female connector and the male connector can be unplugged directly, without removing various cables, and after the operation of the node module 1 is completed, the node module 1 is plugged back into the node bracket 61 directly. Likewise, when the PCIE device 2 needs to be maintained, the PCIE device 2 may be directly unplugged. Therefore, after the interconnecting cable is made into a fixed pluggable connector, blind plugging operation can be realized, and thus, quick switching of different interconnection modes can be realized. Furthermore, the server is not required to be subjected to power-off maintenance, normal operation of the client service is ensured, and the use requirement of the client is met.

Meanwhile, in the actual installation process, the cables to be plugged and unplugged are not required to be searched, and a technician can directly install the node module 1 and the PCIE equipment 2, so that the quick switching of different interconnection modes can be realized. And because the positions of the female connector and the female terminal are fixed, and the volumes of the female connector and the female terminal are larger, the blind plugging operation can be performed by technicians, and therefore the operation flow of the technicians is simplified.

Further, in an alternative embodiment, when the node module 1 is mounted to the node bracket 61 and the PCIE device 2 is mounted to the PCIE bracket 62, the power supply 4 on the device bracket 63 supplies power to the node module 1 and the PCIE device 2.

Meanwhile, in the actual installation process, a technician does not need to independently find and insert a special control line, and can directly install the node module 1 and the PCIE equipment 2, so that the operation flow of the technician is simplified to a certain extent, and the working efficiency of the technician during equipment assembly is improved. And because the positions of the female connector and the female terminal are fixed, and the volumes of the female connector and the female terminal are larger, the blind plugging operation can be performed by technicians, and therefore the operation flow of the technicians is simplified.

Further, in an alternative embodiment, the node bracket 61, the PCIE bracket 62 and the equipment bracket 63 are fixed to the bottom of the mounting cavity by detachable components.

When the customer only needs to use one node module 1, the overall structures of the node bracket 61, PCIE bracket 62, and equipment bracket 63 are not changed. Since only one of the node modules 1 is used, only the other node module 1 and the peripheral cables associated with the other node module 1 need to be removed, thereby meeting the needs of different customers.
