Specifically, the storage performance requirement may include a storage I/O performance requirement, a virtual machine system disk, a storage anti-affinity policy between the logical disks, and a storage reverse affinity policy of the first virtual machine and the second virtual machine (required The storage resources of one virtual machine and the second virtual machine correspond to different logical unit numbers) and the like.

Step 130: Call the IaaS layer management interface to set a logical unit number corresponding to the virtual machine according to the storage performance requirement.

Specifically, the embodiment of the present invention calls the IaaS layer management interface in the cloud computing system to set a logical unit number corresponding to the virtual machine according to the storage performance requirement, and the logical unit represented by the logical unit number is located in the data storage cluster.

In the virtual machine storage resource deployment method provided by the embodiment of the present invention, the virtual machine storage resource description file is first obtained, the storage resource description file is parsed to obtain the storage performance requirement of the virtual machine, and then the IaaS layer management interface is invoked according to the storage performance requirement.

Step 210: Divide the storage device into different RAID groups according to the level of I/O performance.

Specifically, the storage device has different I/O performance due to the storage medium and interface type it employs. In the embodiment of the present invention, the IaaS layer cloud management system in the cloud computing environment divides the storage devices of the IaaS layer into different RAID groups according to the level of I/O performance.

Step 220: Divide each of the RAID groups into multiple logical units, and each logical unit is identified by a logical unit number.

The IaaS layer cloud management system in the cloud computing environment can divide the RAID group into multiple logical units, and then put the logical unit into the data storage cluster. Multiple logical units are included in the same data storage cluster. The logical units in the RAID group can be placed in different data storage clusters or in the same data storage cluster.

Step 230: Receive a virtual machine storage resource description file sent by the Saas layer application.

Specifically, the step 110 of obtaining the virtual machine storage resource description file in the first embodiment includes: receiving the virtual machine storage resource description file sent by the Saas layer application. Because the application has requirements for I/O performance, the virtual machine storage resource description file carries the storage I/O performance requirements of the virtual machine. The generating virtual machine storage resource description file may be automatically generated by the software-as-a-service SaaS layer application according to the storage resource requirement of the application, where the description file includes the storage space requirement of the application and the storage performance requirement (such as storage I/O performance requirement, storage). Anti-affinity strategy) and so on.

In addition, the virtual machine storage resource description file can also come from an open virtual format description file.

Step 240: Parse the storage resource description file to obtain a storage performance requirement of the virtual machine.

The method for parsing the storage resource description file may also obtain the storage space requirement of the virtual machine, and allocate the storage space that meets the requirement for the virtual machine.

Step 250: Call an IaaS layer management interface to set a logical unit number corresponding to the virtual machine according to the storage I/O performance requirement, and an I/O performance of the logical unit corresponding to the logical unit number is higher than the storage I/O performance. Claim.

Specifically, in this embodiment, the IaaS layer management interface is invoked to set a logical unit number corresponding to the virtual machine according to the storage I/O performance requirement of the virtual machine, and the storage I/O performance of the logical unit corresponding to the logical unit number is higher than the foregoing. Storage I/O performance requirements, this logical unit is located in the data storage cluster.

The different logical units in the data storage cluster correspond to different storage I/O performances.

In the virtual machine storage resource deployment method provided by the second embodiment of the present invention, by configuring a virtual unit with a storage I/O performance higher than a requirement, the virtual machine can meet the requirement of high I/O performance, and the present invention is implemented. For example, the storage resources that meet the requirements can be configured according to the different storage I/O performance requirements of the virtual machine, and the utilization efficiency of the storage resources is improved.

For a more detailed understanding of the virtual machine storage resource deployment method provided by the embodiment of the present invention, a specific application scenario is given below.

In this application scenario, the application of the Saas layer needs to establish two virtual machines VM1 and VM2. In order to ensure reliability, the logical volumes of VM1 and VM2 need to be placed on different LUNs. In addition, VM1 and VM2 belong to a storage I/O type virtual machine, and the number of input/output operations per second (Input/Output Operations Per Second, IOPS) is as high as 500 IOPS.

Referring to FIG. 4, a virtual machine storage resource deployment method provided by Embodiment 3 of the present invention includes the following steps:

Step 310: The IaaS layer cloud management system divides the storage devices into different RAID groups according to the level of I/O performance.

As one of the embodiments, the SSD, the SAS, and the SATA are divided into three disk arrays (Redundant Arrays of Independent Disks, RAID) according to the storage medium type, interface type, and I/O performance of the storage device. The storage I/O performance of the three RAID groups is reduced in turn. The SSD RAID group meets the high I/O performance requirements. The SAS meets the common I/O performance requirements and the SATA performance is low. It is mainly used for system backup.

Step 320: The IaaS layer cloud management system divides each RAID into multiple logical units, and places the logical units into the data storage cluster.

Among them, LUNs with different I/O performance in the data storage cluster or data storage clusters with different I/O performance can meet the I/O performance requirements of different virtual machines. The logical units in the RAID group can be placed in different data storage clusters or in the same data storage cluster. Correspondingly, there may be LUNs with the same I/O performance in the data storage cluster, and the I/O performance may not exist. The same LUN.

In this application scenario, for example, LUN0, LUN1, and LUN2 correspond to SSD storage, and LUN3 and LUN4 correspond to SAS storage, LUN5, and LUN6 correspond to SATA storage. LUN0, LUN1, and LUN2 are placed in the same data storage cluster, and LUN3-LUN6 is placed in another data storage cluster.

Steps

310 and 320 are all implemented by an IaaS layer cloud management system. For the VMware scenario, the IaaS layer cloud management system is specifically VMware vCloud director.

Step 330: The VNF management system receives a virtual machine storage resource description file sent by the Saas layer application.

The virtual machine storage resource description file is specifically VNFD, and the application manufacturer describes the virtual machine storage requirement according to the application requirement, and uploads to the VNF management system through the WEB client network. The VNF management system can be located in the PaaS layer of the cloud computing system.

Step 340: The VNF management system parses the VNFD to obtain a storage performance requirement of the virtual machine, and sends the storage performance requirement to the IaaS layer cloud management system.

Among them, the VNFD describes that the virtual machine VM1 and the virtual machine VM2 store have anti-affinity and are required to be placed on different LUNs. In addition, I/O performance requirements are 500I/OPS.

Step 350: The IaaS layer cloud management system creates virtual machines VM1 and VM2.

Specifically, the IaaS layer cloud management system allocates server resources and storage resources according to resource requirements (including computing resource requirements, network resource requirements, storage requirements, and the like) of the virtual machines VM1 and VM2.

The process of allocating storage resources by the IaaS layer cloud management system includes the steps of creating a storage mapping relationship, and the action of applying for the physical resources is implemented by step 360.

Step 360: The VNF management system invokes the IaaS layer management interface to select two logical units that meet the I/O performance requirements according to the storage requirements of the virtual machines VM1 and VM2, and sets the virtual machines VM1 and VM2 to correspond to different logical unit numbers.

Specifically, the VMs VM1 and VM2 have I/O performance requirements and require storage anti-affinity. The VNF management system calls the IaaS layer management interface to select two logical unit numbers LUN0 and LUN1 that meet the I/O performance requirements, and the settings are set. The virtual machine VM1 corresponds to LUN0, and VM2 corresponds to LUN1. In addition, by calling the IaaS layer management interface, the IaaS layer cloud management system will store the I/O performance requirements and storage anti-affinity policies of the virtual machines VM1 and VM2.

After the LUNs of VMs VM1 and VM2 are set up, the VMs are powered on through the IaaS layer management system to complete the VM creation process. The virtual machine creation process provided by this application scenario can be To meet the storage I/O performance and storage anti-affinity policies of the active and standby virtual machines, improve the reliability of the active and standby virtual machines, and select appropriate storage deployment based on the I/O defined by the virtual machine to improve storage resources. usage efficiency.

Further, in this application scenario, the IaaS layer cloud management system finds that the storage capacity and storage I/O performance of the LUN0 cannot meet the requirements of the virtual machine VM1, and the VM1 needs to be migrated from the LUN0 to the other LUN. The cloud management system automatically triggers or manually triggers a VM1 hot migration request.

The virtual machine storage resource deployment method provided by the third embodiment of the present invention further includes the following steps:

Step 370: The IaaS layer cloud management system receives the VM1 hot migration request, and obtains current deployment information of the virtual machine VM1.

The hot migration request is used to indicate that VM1 needs to be hot migrated, including the source LUN of VM1, that is, LUN0.

The IaaS cloud management system obtains the current deployment information of the virtual machine VM1. The deployment information includes the location of the logical disk of the VM1, the I/O performance requirement, and the location of the logical disk of the virtual machine VM2. In this embodiment, the logical disk of the backup virtual machine VM2 is located on the LUN1, and the LUN2-LUN6 is idle, and the I/O performance of the LUN0 corresponding to the VM1 is high.

Step 380: The IaaS cloud management system sets the migration logical unit number corresponding to VM1 according to the current deployment information of VM1 and the storage anti-affinity policy.

Specifically, the IaaS cloud management system determines that VM1 cannot be migrated to the logical unit LUN1 of VM2 according to the current deployment information of VM1 obtained in step 380, the previously stored storage reverse affinity policy, and the storage I/O performance, and finally sets LUN2. The migration logical unit number corresponding to VM1 completes the hot migration process of VM1.

In this application scenario, when a virtual machine is deployed, the storage resource is selected according to the I/O performance requirements of the virtual machine. When the initially allocated virtual machine storage resource cannot meet the requirements, the virtual machine is hot-migrated and combined with hot migration. The storage performance of a virtual machine requires the selection of target storage resources that meet the requirements. Compared with the prior art, the embodiment of the present invention can better meet the storage performance requirements of the virtual machine and improve the utilization efficiency of the storage resource.
