Detailed Description

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1a shows a flow chart of a server resource allocation method in the prior art. And part of cloud manufacturers support software and hardware cooperation based on an open source framework (such as openstack) to realize the pluggable equipment. At present, a server in the server field deploys PCIE physical devices in advance, and the server loads all PCIE type devices by default.

In the prior art, a user may send a PCIE resource request for applying or releasing PCIE resources (network card/hard disk, etc.) through a user operation interface. And the user operation interface sends the PCIE resource request to the dispatching system. The scheduling system is a continuously working daemon, receives and responds to PCIE resource requests from users, and is responsible for creating and destroying instance control forwarding. And the scheduling system forwards the PCIE resource request to the complex network system, and finally reaches the target server cluster through the forwarding of the multi-stage network switch. The target server cluster is responsible for managing the server nodes, i.e., the device systems, under the cluster. And the equipment system sends the PCIE resource request to the equipment resource receiving system. The device resource receiving system is designed based on open source nova and is very complex. The device resource receiving system forwards the PCIE resource request to the device resource allocation system (a process running in the server node OS) to be responsible for executing real PCIE resource allocation and release. After the PCIE resources are allocated, the server is triggered to restart. The server will load the Option ROM (optional memory) of all PCIE devices when restarting. After the Option ROM of all PCIE devices is loaded, the server enters an OS (operating system), the OS can load PCIE resources applied by a user, for example, the user applies for 4 network cards and 4 disks, when the server enters the OS, the resources can be loaded, and the OS can see that the device has 4 network cards and 4 hard disks.

Fig. 1b is a flow chart illustrating a server resource allocation method of the present disclosure. And a management control chip with a BMC function is added at the PCIE equipment end and is named as equipment BMC. The user can send the PCIE resource request to the device BMC only through a simple general network system. The device BMC forwards the PCIE resource request to a device resource allocation system (a process running in the device OS), and is responsible for performing PCIE resource allocation and release. After the resources are allocated, the server is triggered to restart to enable the resources requested by the user to take effect. The server may directly access the OS without going through the BIOS (Basic Input Output System ).

The design using the BMC as the control center shown in fig. 1b only needs 6 steps (the design in fig. 1a is completed in at least 9 steps, and each system in the system comprises a plurality of subsystems) to realize rapid resource allocation, so that the complexity of the process is greatly simplified, the possibility of error is reduced, and the resource allocation time is shortened. Meanwhile, the design of the present disclosure is more general in terms of software and hardware requirements, reduces complexity in system development and maintenance, simplifies deployment, and improves delivery efficiency. Through the scheduling scheme taking the BMC as the center, after the user determines to start the equipment, the Option ROM of PCIE equipment is not needed to be loaded in the server starting stage, so that the server starting time is greatly shortened, the resource waste is reduced, and the user experience is improved.

Fig. 2 shows an architecture diagram of a server resource allocation system to which the present disclosure may be applied. A server resource allocation system comprising:

a terminal, equipped with a device BMC (Baseboard Management Controller ), a device resource allocation system and a PCIE (peripheral component interconnect express, high-speed serial computer expansion bus) device set, where the device BMC is configured to receive a PCIE resource request of a user and forward the PCIE resource request to the device resource allocation system, the device resource allocation system is configured to select a target PCIE device from the PCIE device set according to the PCIE resource request and allocate the target PCIE device to the user, and the device BMC is configured to send a server restart request for loading the target PCIE device to a server;

and the server is configured to receive a server restarting request sent by the device BMC and load PCIE devices indicated in the server restarting request.

The server can be provided with a server BMC, the server BMC can realize the functions of relevant control, information supervision and the like of the server, and the server BMC is a platform for intuitively presenting server information. The server client may obtain the server information by accessing the server BMC. The performance of the server is related to not only the CPU but also the PCIE devices mounted, and common PCIE devices include raid (redundant arrays of independent disks, disk array), gpu (graphics processing unit, graphics processor), nic (network interface controller ) card, hba (host bus adapter) card, fpga (field programmable gate array ), and the like. When the server leaves the factory, different PCIE devices (one or more matched devices) are configured according to the requirements. The BMC needs to obtain type, version information, vendor information, status information, bandwidth information, temperature information, and the like of the PCIE device. Currently, when each PCIE device is adapted, the BMC needs to be independently developed and maintained, and when the model is changed and the requirement is changed (PCIE device collocation is changed), the BMC code needs to be modified for adaptation.

The device BMC is added on the PCIE device side and used for managing and controlling all PCIE devices. The device BMC chip structure is basically the same as the server BMC, but with a slight difference in functionality.

The specific flow is shown in fig. 2:

1. and filling in the required PICE resources by the user through an operation interface on the terminal, and then generating a PCIE resource request by background software of the operation interface and sending the PCIE resource request to the BMC. For example, the user requests 2 net cards, 1T disk.

2. The device BMC forwards the resource request to the device resource allocation system.

3. And the device resource allocation system selects a target PCIE device from a plurality of selectable PCIE devices according to the PCIE resource request. For example, 2 out of 10 network cards are randomly selected. A disk with a capacity of 1T is randomly selected from 20 disks, and if all the disks do not reach 1T, a plurality of disks may be selected to be allocated to the user, for example, 2 disks with a capacity of 0.5T.

Optionally, attribute information of PCIE devices such as number, capacity, speed, brands and the like may be specified in the PCIE resource request of the user. The device resource allocation system can obtain attribute information of all PCIE devices, and then match with PCIE resource requests of users. If the number of PCIE devices that can be successfully matched is greater than the user's demand, the number of PCIE devices that can be matched may be randomly selected. Optionally, if some attribute information is not specified by the user, PCIE devices with better performance may be preferentially allocated to the user, for example, although the user requests a 0.5T disk, a 1T disk may be allocated under the condition of abundant resources, so that the user can conveniently expand capacity later, and device switching is not required.

Optionally, a history record of the user's service can be collected, and relevant information of expansion and contraction of the user can be counted. The resource demand of the user is predicted, and a prediction model can be trained in advance to predict by using the history of the user. And setting a distribution coefficient according to the probability of capacity expansion. For example, if the probability is increased by 90%, the allocation coefficient may be 1.9, i.e. 1.9 times the number of resources requested by the user, and if the user requests 1T disk, 1.9T may be allocated. If the predicted user capacity reduction, namely the capacity expansion probability is 0, the allocation coefficient is 1, and the resources are allocated completely according to the number of the resources requested by the user.

4. The device resource allocation system informs the device BMC which resources are allocated after the resources are allocated. The device BMC will then notify the server to restart to load these resources.

5. The server restarts to enter the operating system and loads the allocated PCIE resources.

The traffic data of the user, after arriving at the terminal, is directed to the PCIE resources allocated to it, for example, by modifying the packet address, so that the destination address of the user packet is modified to the address of the PCIE device allocated to him.

The system provided by the embodiment of the present disclosure allocates PCIE resources to users according to PCIE resource requests of the users, instead of allocating fixed resources to the users, thereby implementing device elastic provisioning and on-demand allocation, and making devices more intelligent. By installing the device BMC on the PCIE device side, the PCIE device can be flexibly managed, and the elastic expansion capacity, the effectiveness and the reliability of the cloud server product are enhanced. Cloud resources required by customers can be delivered quickly without a complex network, so that the deployment time of a single node is saved by more than a minute level.

In some optional implementations of this embodiment, the server is further configured to: sending a request to the device BMC to not load the optional memory; the device BMC is further configured to: and setting that the optional memory (Option ROM) of the PCIE equipment allocated to the user in the PCIE equipment set is unavailable according to the request of not loading the optional memory. The optional memory of the PCIE device is loaded when the default server is restarted under normal conditions, and after the user determines to start the device, the Option ROM is not required to be loaded in the server starting stage by using the scheduling scheme taking the BMC as the center, so that the starting time of the server is greatly shortened, the resource waste is reduced, and the user experience is improved.

In some optional implementations of this embodiment, the server includes a server BMC, signaling transmission is performed between the device BMC and the server BMC through an I2C interface by using an intelligent platform management interface protocol, and service data transmission is performed through a network interface.

The I2C bus only needs one data line and one clock line, the bus interface is integrated in the chip, a special interface circuit is not needed, and a filter of the on-chip interface circuit can filter burrs on bus data. Therefore, the I2C bus simplifies the PCB wiring of the hardware circuit, reduces the system cost and improves the system reliability. Because the I2C chip is not connected with the system except the two wires and a small amount of interrupt wires, the standardization and modularization of the I2C interface can be realized through the common IC of a user, and the I2C interface can be reused conveniently.

The I2C bus is a true multi-master bus, and if two or more hosts initialize data transfer at the same time, data corruption can be prevented by collision detection and arbitration, each device connected to the bus has a unique address, and any device can act as both a master and a slave, but only one master is allowed at the same time. The data transmission and address setting are set by software, and are very flexible. The addition and deletion of devices on the bus does not affect the normal operation of other devices. The server BMC sends control instructions to the device BMC and receives control instructions from the device BMC. The I2C bus is therefore particularly suitable for communication between the server BMC and the device BMC.

The signaling between the server and the device is transmitted through the I2C interface, so that the stability and reliability of the signaling can be ensured, and the telescoping performance of the server is ensured. The service data is transmitted through the network interface, so that the data transmission speed can be improved, and the smoothness of the service is ensured.

And the IPMI (Intelligent Platform Management Interface) protocol is adopted for communication, so that the product has universality, can be compatible with products of different manufacturers, and can reduce the production cost.

IPMI can span different operating systems, firmware and hardware platforms, and can intelligently monitor, control and automatically report back the operation status of a large number of servers so as to reduce the cost of the server system.

In some optional implementations of this embodiment, signaling transmission is performed between the device BMC and the device resource allocation system through a KCS interface, and service data transmission is performed through a network interface. The KCS interface is a sub-module under the BMC, and the initialization of the sub-module, including channel selection, clock enabling, and register mapping address (0 xCA2 default) are all completed by the BMC driver. After the KCS interface is initialized as necessary, the BIOS can directly access the KCS interface. The KCS interface is used to facilitate communications using IPMI (Intelligent Platform Management Interface ) protocols. The product has universality, can be compatible with products of different manufacturers, and can reduce the production cost.

The signaling between the device BMC and the device resource allocation system is transmitted through the KCS interface, so that the time delay can be reduced, the stability and reliability of the signaling are improved, and the expansion performance of the server is ensured. The service data is transmitted through the network interface, so that the data transmission speed can be improved, and the service fluency is ensured.

With continued reference to fig. 3, a flow 300 of one embodiment of a server resource allocation method according to the present disclosure is shown. The server resource allocation method comprises the following steps:

step 301, a PCIE resource request of a user is received.

In this embodiment, the execution body of the server resource allocation method (for example, the terminal shown in fig. 1) may receive the PCIE resource request input by the user through a wired connection manner or a wireless connection manner. The user can send a PCIE resource request for applying or releasing PCIE resources (network card/hard disk, etc.) through a user operation interface of the terminal. For example, the user applies for 4 network cards and 4 disks.

Step 302, selecting a target PCIE device from the PCIE device set according to the PCIE resource request, and allocating the target PCIE device to the user.

In this embodiment, a target PCIE device is selected from a plurality of optional PCIE devices according to a PCIE resource request. For example, 2 out of 10 network cards are randomly selected. A disk with a capacity of 1T is randomly selected from 20 disks, and if all the disks do not reach 1T, a plurality of disks may be selected to be allocated to the user, for example, 2 disks with a capacity of 0.5T.

Optionally, attribute information of PCIE devices such as number, capacity, speed, brands and the like may be specified in the PCIE resource request of the user. The device resource allocation system can obtain attribute information of all PCIE devices, and then match with PCIE resource requests of users. If the number of PCIE devices that can be successfully matched is greater than the user's demand, the number of PCIE devices that can be matched may be randomly selected. Optionally, if some attribute information is not specified by the user, PCIE devices with better performance may be preferentially allocated to the user, for example, although the user requests a 0.5T disk, a 1T disk may be allocated under the condition of abundant resources, so that the user may expand capacity later, and no handover is required.

Step 303, a restart server request indicating to load the target PCIE device is sent to the server.

In this embodiment, the device BMC may notify the server to restart to load the target PCIE device assigned to the user. The server restarts to enter the operating system or BIOS and loads the allocated PCIE resources. The server selects whether to enter the BIOS or OS according to the user's settings.

The traffic data of the user, after arriving at the device, is directed to the PCIE resource assigned to it, for example, by modifying the packet address, and modifying the destination address of the user packet to the address of the PCIE device assigned to him.

According to the method provided by the embodiment of the disclosure, management control chips such as BMC are added at the PCIE equipment end, such as a server needs N resources, N kinds of resource information are notified to the PCIE equipment side BMC through a user operation interface, the communication protocol adopts IPMI or a custom communication protocol, and the equipment resource distribution system acquires the resource information of the equipment BMC, so that N kinds of resources are provided, the external environment is not relied on, the flow is greatly simplified, and the reliability of resource change and the delivery efficiency are improved.

In some optional implementations of the present embodiment, the method further includes: if the PCIE equipment usage rate allocated to the user is detected to be smaller than a first preset threshold value, releasing a part of PCIE equipment allocated to the user; and if the PCIE equipment usage rate allocated to the user is detected to be larger than a second preset threshold value, selecting a part of PCIE equipment from the PCIE equipment set to be allocated to the user. In addition to expanding or shrinking according to the configuration of the user, the technical scheme of the present disclosure also supports adaptive expansion or shrinking. The usage rate of PCIE devices in the predetermined time may be counted, if the usage rate is lower than a first predetermined threshold (e.g., 50%), which indicates that the idle rate of PCIE devices is high, and a portion of resources may be released to be reallocated to other users, thereby improving the resource utilization rate. If the usage rate is greater than a second predetermined threshold (e.g., 95%), some PCIE resources may be reassigned to the user, sharing the pressure of PCIE devices assigned to the user, and implementing load balancing.

With continued reference to fig. 4, a flow 400 of yet another embodiment of a server resource allocation method according to the present disclosure is shown. The server resource allocation method comprises the following steps:

step 401, a PCIE resource request of a user is received.

And step 402, selecting a target PCIE device from the PCIE device set to be allocated to the user according to the PCIE resource request.

Steps 401-402 are substantially the same as steps 201-202 and are therefore not described in detail.

Step 403, a request sent by the server to not load the optional memory is received.

In this embodiment, the user may determine the PCIE device to be started next time, and the user issues the instruction to the server through the operation interface of the terminal. The server informs the device BMC to control loading of the corresponding Option ROM and not loading of other types of devices. If the server is started or restarted without entering the BIOS, the server can be controlled to not load any Option ROM, so that the starting or restarting time under the server can be greatly shortened, the service on-line and deployment are accelerated, and the operation and maintenance time is shortened.

Step 404, setting that optional memory of PCIE devices allocated to the user in the PCIE device set is unavailable according to the request.

In this embodiment, the flag bit of the Option ROM allocated to the PCIE device of the user may be set to be unavailable, and the Option ROM may not be loaded when the server is restarted.

Step 405, a restart server request indicating to load the target PCIE device is sent to the server.

In this embodiment, the device BMC may notify the server to restart to load the target PCIE device assigned to the user. The server restarts to directly enter the operating system, loads the allocated PCIE resources and does not load the Option ROM.

The optional memory of the PCIE device is loaded when the default server is restarted under normal conditions, and after the user determines to start the device, the Option ROM is not required to be loaded in the server starting stage by using the scheduling scheme taking the BMC as the center, so that the starting time of the server is greatly shortened, the resource waste is reduced, and the user experience is improved.
