BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be clearly and completely described in the following description of the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The data center management system is generally divided into the following layers: physical device layer, resource pool management layer, scheduling layer, and application layer. The resource pool management layer of the data center management system constitutes a resource pool management system, which can provide management and display functions of server resources. The resource pool management system displays resource information of servers within its management scope, including CPU, memory, disk, and network card. The upper system can flexibly schedule and utilize server resources through these resource information.

1 is a flow chart of a method of obtaining server resource information according to an embodiment of the present invention. The method of Figure 1 is performed by the resource pool management system.

101. Send installation information of the temporary operating system to the server, and the installation information is used by the server to install a temporary operating system in the memory of the server.

The temporary operating system may be a full version of the operating system, or may be a cropped version of the operating system. The embodiment of the present invention does not limit this, and the temporary operating system only needs to include components for obtaining server resource information. The installation information includes the configuration file of the temporary operating system, and the like.

Installing and running a temporary operating system in memory without persisting the temporary operating system to the server's disk ensures that the server's disk data is not corrupted.

As an optional embodiment, the temporary operating system may be a Linux mirroring system, but the embodiment of the present invention does not limit the specific form or version of the temporary operating system.

As an optional embodiment, the server may be a blade server, but the embodiment of the present invention does not limit the specific form of the server.

102. Send a resource information acquisition request to the server.

The resource information acquisition request is used to request resource information of the server, for example, a server discovery command (Discovery Server( )), but the specific form of the resource information acquisition request is not limited in the embodiment of the present invention.

103. The temporary operating system of the receiving server acquires the resource of the server obtained according to the resource information request. Source information.

In the embodiment of the present invention, a temporary operating system is installed in the memory of the server, and the resource information of the server is obtained by using the temporary operating system, so that the resource information of the server can be flexibly obtained, and the versatility and limitations brought by the BMC mode are solved.

Once the temporary operating system is running on the server, you can get the server's resource information in any way. For example, a temporary operating system can obtain resource information for a server through IPMI, HPI (Host Port Interface), or other means. The HPI is a parallel interface to the host computer and is mainly used by DSP (Digital Signal Processor) to communicate with other buses or CPUs. The embodiment of the present invention does not limit the manner in which the server obtains resource information. Thus, the embodiment of the present invention is not limited to obtaining the resource information of the server through the IPMI specification, and the implementation manner is more flexible.

Alternatively, the loading of the temporary operating system can be implemented using the existing PXE (Pre-boot Execution Environment) protocol. PXE is a protocol designed by Intel to enable computers to boot over the network. The protocol is divided into two ends: PXE client (client) and PXE server (server). The PXE client is in the ROM (Read-Only Memory) of the server's network card. When the server is started, the BIOS (Basic Input Output System) transfers the PXE client to the memory and displays the command menu. After the user selects, the PXE client will be downloaded to the remote operating system and downloaded to the local network for operation. In simple terms, PXE is used to load the remote OS to the local server's network protocol.

The general workflow for PXE loading is: The blade server pre-opens the PXE function of the NIC and boots from the network. The DHCP (Dynamic Host Configuration Protocol) server gives the blade server an IP (Internet Protocol) address and indicates the IP address of the next hop TFTP (Trivial File Transfer Protocol). The blade server automatically goes to the TFTP server (below the srv/tftpboot/uhm folder) to download the operating system installation information, such as the pxelinux.O file and the configuration file in the pxelinux.cfg directory. The configuration file is a file named after the MAC (Media Access Control) address of the PXE port of the blade server in the resource management system. The blade server then performs operations such as loading the kernel, mirroring, etc. to install the operating system based on the configuration file.

As mentioned above, the loader needs to start the DHCP server, but it interferes with the DHCP server in the user's network. According to different network architectures, the embodiment of the present invention can be isolated by using a "VLAN" (Virtual Local Area Network) or a "VLAN + DHCP relay" to solve the interference problem of the DHCP server.

Specifically, as an embodiment, before step 101, the resource pool management system may set a VLAN on the access switch of the server, and connect the access switch and the server through the VLAN. The resource pool management system receives a load request sent by the server for requesting installation information of the temporary operating system through the VLAN. At this time, in step 101, the resource pool management system may send the installation information of the temporary operating system to the server through the VLAN when receiving the loading request.

Optionally, as another embodiment, the VLAN is further connected to the aggregation switch of the access switch and the server. In this case, you can set the DHCP relay of the VLAN on the aggregation switch of the server, which points to the DHCP server inside the resource pool management system.

Optionally, as another embodiment, after step 103, the resource pool management system may delete the VLAN and send a restart command to the server, where the restart command is used to instruct the server to run a normal operating system. A normal operating system is the complete operating system installed on the server's disk.

In addition, the temporary operating system of the embodiment of the present invention can be used not only to obtain resource information of the server, but also to configure the server. Optionally, as another embodiment, the resource pool management system may send a configuration command to the server, where the configuration command is used to configure the server by using a temporary operating system. example

^, configuration commands can be used to perform RAID (Redundant Arrays of Inexpensive Disks or Redundant Array of Independent Disks, redundant array of inexpensive disks or redundant array of independent disks) configuration, BIOS custom configuration, MAC address configuration, vHB A (Virtual Host Bus Adapter, virtual host bus adapter) configuration, etc., to achieve automatic configuration of the server or fast failure recovery.

Thus, the embodiment of the present invention provides a method for discovering a server of a tree machine, which provides basic data for the resource pool management system of the data center, and the discovery mechanism can be applied to the configuration of the tree machine, thereby providing a convenient way for resource scheduling of the data center.

2 is a flow chart of a method for obtaining server resource information according to another embodiment of the present invention. The method of Fig. 2 is executed by the server and corresponds to the method of Fig. 1, and therefore, the repeated description will be appropriately omitted. As an optional embodiment, the server may be a blade server, but the embodiment of the present invention does not limit the specific form of the server.

201. Receive installation information of the temporary operating system from the resource pool management system.

202. Install a temporary operating system in the server's memory according to the installation information.

203. When receiving the resource information acquisition request sent by the resource pool management system, obtain the resource information of the server by using the temporary operation system.

The resource information obtaining request is used to request resource information of the server, for example, a server discovery command (Discovery Server( )), but the specific form of the resource information obtaining request is not used in the embodiment of the present invention. Limitation.

204. Send resource information of the server to the resource pool management system.

Alternatively, the loading of the temporary operating system can be implemented using the existing PXE (Pre-boot Execution Environment) protocol. PXE loading requires a DHCP server to be started, but it interferes with the DHCP server in the user's network. According to different network architectures, the embodiment of the present invention can be isolated by using a "VLAN" (Virtual Local Area Network) or a "VLAN + DHCP relay" to solve the interference problem of the DHCP server.

Optionally, as an embodiment, before step 102, the server may send a loading request for requesting installation information of the temporary operating system to the resource pool management system by using a VLAN set by the resource pool management system on the access switch of the server. .

Optionally, as another embodiment, the VLAN is further connected to the aggregation switch of the access switch and the server. The DHCP relay of the VLAN is set on the aggregation switch of the server, and the DHCP relay points to the DHCP server inside the resource pool management system.

Optionally, as another embodiment, after step 204, the server may receive a restart command sent by the resource pool management system, and restart the running normal operating system according to the restart command. A normal operating system is the complete operating system installed on the server's disk.

In addition, the temporary operating system of the embodiment of the present invention can be used not only to obtain resource information of the server, but also to configure the server. Optionally, as another embodiment, the server may receive a configuration command sent by the resource pool management system, and configure the server through the temporary operating system according to the configuration command. For example, configuration commands can be used to perform RAID configuration, BIOS custom configuration, MAC address configuration, vHBA configuration, etc., to achieve automated server configuration or fast failure recovery.

FIG. 3 is a schematic flowchart of a process of acquiring server resource information according to another embodiment of the present invention. In the process shown in Figure 3, the switch can include the server's access switch or aggregation switch. In the embodiment of FIG. 3, the installation information of the temporary operating system miniOS may be pre-stored on the data center management system where the resource pool management system or the resource pool management system is located, so that the server can download the installation information of the miniiOS by using the PXE loading mode.

301. The resource pool management system sends a VLAN setting command SetVlan( ) to the switch, which is used to set a VLAN on the switch.

The VLAN is connected to at least the loading network port of the server and the corresponding port of the access switch, so that the server can perform PXE loading through the VLAN without loading the operating system to the DHCP server of the user network.

302, this is an optional step. If the Layer 3 gateway is on a Layer 3 LAN switch, the VLAN also needs to be connected to the aggregation switch and the access switch. In this case, the resource pool management system sends a DHCP relay setup command SetDHCPRelay( ) to the aggregation switch to set the DHCP relay on the aggregation switch. The DHCP relay points to a DHCP server inside the resource pool management system.

In this way, when the server performs PXE loading, the miniOS installation information can be obtained directly from the resource pool management system without the problem that the server's DHCP request is responded to by the user network's DHCP server.

303. When the server starts, according to the PXE loading mode, the miniOS installation information is obtained from the resource pool management system.

304. The server installs and runs miniOS in the memory of the server according to the installation information of the miniOS. Install and run miniOS in memory without persisting the miniOS to the server's disk, which ensures that the server's disk data is not corrupted.

305. The resource pool management system sends a server discovery command DiscoveryServer( ) to the server, and requests resource information of the server.

306. The server obtains resource information.

For example, the server can obtain its own resource information based on IPMI or HPI by executing the corresponding script of miniOS. However, the embodiment of the present invention does not limit the manner in which the server obtains resource information.

307. The server returns the obtained resource information to the resource pool management system.

308, this is an optional step. The resource pool management system sends configuration commands to the server to configure the server through miniOS, such as RAID configuration, BIOS custom configuration, MAC address configuration, vHBA configuration, etc., to implement automatic server configuration or fast fault recovery.

309. The resource pool management system sends a VLAN deletion command DeleteVlan( ) to the switch, and the command switch deletes the VLAN established in step 301.

310. The resource pool management system sends a restart command Reboot( ) to the server, and the server is restarted.

311, after the server is restarted, enter the normal user OS.

In the embodiment of the present invention, a temporary operating system is installed in the memory of the server, and the temporary operating system is used to obtain The resource information of the server can flexibly acquire the resource information of the server and solve the versatility and limitations brought by the BMC mode.
