Detailed Description

The core of the invention is to provide a management device and a server system of a multi-node server, which can avoid the condition that the server cannot share the modules with the server to interact when any gating control module group fails, and improve the reliability of the multi-node server.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a management apparatus for a multi-node server according to the present invention, the apparatus including:

the selection modules 11 are connected with the servers in a one-to-one correspondence manner and used for sending the control signals generated by the servers corresponding to the selection modules to the gating control module group 12 corresponding to the selection signals when receiving the selection signals generated by the servers corresponding to the selection modules;

each gating control module 12 is connected to each selection module 11, the gating control module 12 is configured to receive a control signal, send the control signal to the server sharing module 13, receive a feedback signal generated by the server sharing module 13 according to the control signal, and send the feedback signal to the selection module 11, so that the selection module 11 sends the feedback signal to a server corresponding to the selection module 11, and N is an integer not less than 2.

In order to improve the reliability of the multi-node server, in the application, a plurality of selection modules 11 are provided, the selection modules 11 are connected with the servers in a one-to-one correspondence manner, N gating control module groups 12 are further provided, each gating control module group 12 is connected with all the selection modules 11, and can receive a control signal sent by each server through the corresponding selection module 11 and send the control signal to the server sharing module 13.

It should be noted that the multi-node server belongs to one of rack servers, and the multi-node server is composed of a plurality of nodes and a management unit, for example, a plurality of servers and SMCs, in the multi-node server, when one server executes a certain job, part of the job can be distributed to other servers through the connection relationship between the nodes to reduce the burden of the server, and in addition, the multi-node server can also be used as a server for storing data, and can be flexibly applied according to the actual situation, and in the multi-node server, each server can share some modules, such as a power supply module, a fan heat dissipation module, a storage module, and the like.

In view of the problem of low reliability of the prior art method for individually managing a multi-node server through SMC, please refer to fig. 2, fig. 2 is a schematic diagram of a prior art structure of a management apparatus for a multi-node server, in which all servers and each server sharing module 13 are connected to SMC, a server sends a control signal to each server sharing module 13 through SMC, and a feedback signal generated by the server sharing module 13 according to the control signal is also sent to the server through SMC, that is, SMC is used as host, since the server and server sharing module 13 are connected only through SMC, when a failure occurs in SMC, it is equivalent to a disconnection between the server and server sharing module 13, which results in no interaction between the server and server sharing module 13, and besides, the requirement of SMC hardware performance specification is high, but also at higher costs.

In this application, specifically, before the server generates the control signal, the server may generate a selection signal, where the selection signal may be a signal set manually, and send the selection signal to the corresponding selection module 11, so that the selection module 11 can send the control signal to the designated gating control module 12, for example, when 2 gating control module groups 12 are provided, since both the two gating control module groups 12 are connected to the selection module 11 corresponding to the server, the server may send the selection signal to the corresponding selection module 11 to send the selection module 11 the control signal to the designated one of the two gating control modules, since a plurality of gating control module groups 12 are provided, which is equivalent to a plurality of hosts being provided, when any one gating control module group 12 fails, the server may send the control signal to the server common module 13 through the other gating control module groups 12, a highly available access link is formed.

The gating control module can also receive a feedback signal generated by the server sharing module 13 according to the control signal and send the feedback signal to the selection module 11 corresponding to the control signal, when the selection module 11 sends the feedback signal to the server corresponding to itself, for example, when the server sharing module 13 is a storage module, the server wants to query the remaining amount of the storage space of the storage module, the server generates a selection signal and sends the selection signal to the selection module 11 corresponding to itself, then generates a control signal containing the queried remaining amount of the storage space and sends the control signal to the designated gating control module group 12 through the selection module 11, the gating control module group 12 sends the control signal to the storage module, the storage module generates a feedback signal containing the remaining amount of the storage space of itself after receiving the control signal, and the gating control module acquires the feedback signal, the feedback signal is sent to the selection module 11, and the selection module 11 sends the feedback signal to the server, that is, the feedback signal is sent to the server through the original path for sending the control signal, and the server can know the remaining amount of the storage space of the storage module according to the feedback signal.

In summary, by providing the selection module 11 and the N gating control module groups 12 connected to the servers in a one-to-one correspondence manner, the gating control module groups 12 are respectively connected to the selection modules 11, when receiving a selection signal generated by a server corresponding to the selection module 11, the selection module 11 sends a control signal generated by the server to the gating control module group 12 corresponding to the selection signal, the gating control module group 12 sends the control signal to the server sharing module 13, the gating control module group 12 is further configured to receive a feedback signal generated by the server sharing module 13 according to the control signal, and send the feedback signal to the server corresponding to the selection module 11 through the selection module 11, wherein the server sharing module 13 includes a fan module, a storage module, and a power module. The condition that the server cannot interact with the server sharing module 13 when any gating control module group 12 fails can be avoided, and the reliability of the multi-node server is improved.

On the basis of the above-described embodiment:

as a preferred embodiment, receiving the control signal and sending the control signal to the server common module 13 includes:

when not less than 2 control signals are received at the same time, according to the preset priorities of the servers, the control signal generated by the server with the highest priority among the received control signals is sent to the server sharing module 13.

In order to avoid the situation that the server sharing module 13 receives multiple control signals at the same time to cause logic confusion, in the present application, considering that in an actual situation, there may be a situation that multiple servers simultaneously send control signals to the same gating control module group 12 through the respective corresponding selection modules 11, different priorities are set in each gating control module group 12 pair in advance, when receiving multiple control signals, by negotiating two control signals, that is, the gating control module group 12 sends the control signal corresponding to the server with the highest priority among the control signals to the server sharing module 13 by judging the priority corresponding to the server sending the control signals, this process may be implemented by using software of a preset software protocol, for example, when the server a and the server B send control signals to the same gating control module group 12 through the respective corresponding selection modules 11, the priority of the server a is preset in the gating control module group 12 as 10, the priority of the server B is preset as 1, at this time, the gating control module group 12 sends the control signal sent by the server a to the server sharing module 13, and when the server a finishes the interaction with the server sharing module 13, the gating control module group 12 sends the control signal of the server B to the server sharing module 13, so as to avoid the situation that the server sharing module 13 receives a plurality of control signals at the same time to cause logic disorder.

As a preferred embodiment, receiving the control signal and sending the control signal to the server common module 13 includes:

when not less than 2 control signals are received within a preset time period, the control signal received first is sent to the server sharing module 13 according to the time sequence of receiving each control signal.

In order to avoid the situation that the server sharing module 13 receives multiple control signals at the same time to cause logic confusion, in the present application, it is considered that in an actual situation, there may exist a situation that multiple servers simultaneously send control signals to the same gating control module group 12 through their respective corresponding selection modules 11, but due to the difference in the transmission speeds of wires and the difference in the response speeds of the selection modules 11, the time when the gating control module group 12 receives the control signals sent by the respective servers always has a precedence order, for example, the precedence time interval of receiving the respective control signals may be several milliseconds or longer, the gating control module group 12 may send the control signal received first to the server sharing module 13 according to the precedence order of receiving the respective control signals within a preset time period, when the control signal received first is sent out or the server finishes the interaction with the server sharing module 13, the gating control module 12 then sends the second received control signal to the server common module 13. The preset time period may be a very short time period, the gating control module 12 may periodically detect the sequence of the received control signals, and since only the control signal received first is sent to the server sharing module 13, the situation that the server sharing module 13 receives multiple control signals at the same time to cause logic confusion is avoided.

As a preferred embodiment, the respective servers are connected via SMBus to one-to-one corresponding selection modules 11.

In order to reduce the wire cost and the circuit complexity, in the application, it is considered that a plurality of signals need to be transmitted between the server and the selection module 11 corresponding to the server, when the selection module 11 receives the selection signal, the selection module 11 sends a control signal to the gating control module group 12 corresponding to the selection signal, the selection module 11 also obtains a feedback signal sent by the gating control module group 12 and sends the feedback signal to the server, and an SMBus (System Management Bus) includes buses with three functions, namely a data Bus, an address Bus and a control Bus, wherein the data Bus is used for transmitting data information, for example, when the selection module 11 receives the feedback signal, the feedback signal can be sent to the server through the data Bus so that a worker can check the feedback signal; the address bus is used for transmitting address signals, for example, when a server wants to inquire an address of a hard disk in a storage module belonging to the server sharing module 13, the address signals can be sent to the selection module 11 through the address bus, so that the selection module 11 sends the address signals to the gating control module group 12, and the gating control module group 12 sends the address signals to the storage module; for example, when the selection module 11 is connected to a plurality of gating control module groups 12, the server may send a signal including the designated gating control module group 12, that is, a selection signal, to the selection module 11 through the control bus, and the selection module 11 may know that the control signal needs to be sent to the designated gating control module group 12. Each server is connected with the selection modules 11 which are in one-to-one correspondence through a system bus, in addition, the connection between the selection modules and the gating control module group, the connection inside the gating control module group and the connection between the gating control module group and the server sharing module can be connected through SMBus, the functions of three buses are realized through one bus, the cost of using various wires is saved, and the complexity of the lines is reduced.

As a preferred embodiment, the selection module 11 is specifically configured to, when receiving a selection signal containing an address of the gating control module group 12 generated by a server corresponding to the selection module, send a control signal generated by the server to the gating control module group 12 corresponding to the address of the gating control module group 12.

In order to send the control signal to the gating control module group 12 corresponding to the selection signal, in the present application, each gating control module group 12 is connected to each selection module 11, so that the gating control module group 12 corresponding to the selection signal can be determined by the address of each gating control module group 12. Specifically, the addresses of the respective gating control module groups 12 connected to the selection module 11 may be defined in advance, during actual operation, the selection module 11 may determine the gating control module group 12 corresponding to the selection signal according to the address definition of each gating control module group 12, for example, when two gating control module groups 12 exist, addresses of the two gating control module groups 12 are defined in advance, as # a123 and # a222, when the server wants to send a control signal to the server common module 13 through the gating control module corresponding to the # a222 address, the server sends a selection signal containing the # A222 address to the selection module 11, the selection module 11 can determine the designated gating control module group 12 according to the address in the selection signal after receiving the selection signal, the control signal is then sent to the gated control module group 12 corresponding to the # a222 address.

As a preferred embodiment, the selection module 11 is a MUX.

In order to select any one of the gating control module groups 12 connected to the selection module 11 according to the selection signal sent by the server, in the present application, the selection module 11 is a MUX (Multiplexer), the MU may be a Multiplexer or a Multiplexer, for example, a 2-to-1 Multiplexer or a 4-to-1 Multiplexer, and the present application does not limit the MUX to be actually used. The MUX is easy to control and fast in response, can receive the selection signal of the server fast and send the control signal to the gating control module group 12 corresponding to the selection signal fast according to the selection signal, and has the advantages of small size and low power consumption.
