example 1

[0107] Example 1, the process of creating an image file in a logical volume:

[0108] In the basic architecture of Openstack, the cinder component is used as its basic block storage management. When the IPSAN disk array is used as the storage backend of cinder, the connection between the IPSAN disk array and the host where cinder is located is as follows: image 3 As shown, the host where cinder is located communicates with the service port of the disk array through a TCP / IP network connection. When the cinder end initiates a request to create a mirror image file in the IPSAN disk array, it first passes through the Hub on the control plane ( The management port of the hub) sends a volume creation command to the IPSAN disk array, and the IPSAN disk array returns after creating the volume (for example, the first logical volume).

[0109] Then cinder initiates the operation of adding the first logical volume to the mapping group to the management port of the IPSAN disk array thr...

[0112] Example 2, virtual machine startup process:

[0113] In the basic architecture of Openstack, the cinder component is used as its basic block storage management. When the IPSAN disk array is used as the storage backend of cinder, and nova-compute (computing component, or computing server) also uses the IPSAN disk array as the storage backend of the virtual machine, where the service of the IPSAN disk array and nova-compute resides The connection between the hosts such as Figure 4 As shown, the host where nova-compute is located communicates with the service port of the IPSAN disk array through a TCP / IP network connection.

[0114] When the nova-compute terminal initiates a request to start a virtual machine from the cloud disk, first the nova-compute terminal initiates the operation of adding the volume (for example, the first logical volume) to the mapping group to the management port of the IPSAN disk array through the TCP / IP channel , the disk array will add the ho...

Abstract

The invention discloses a method for creating a mirror image file in a logical volume and starting a virtual machine, and a server. The technical problem of relatively high requirements on local hardware resources for creating the mirror image file in the logical volume is solved. The method for creating the mirror image file in the logical volume comprises the following steps: the server sends a creation request to a cloud magnetic array, wherein the creation request is used for requesting the cloud magnetic array to create a first logical volume; the server initiates an operation of adding the first logical volume to a mapping group to the cloud magnetic array so as to add the first logical volume to a first mapping group, wherein the first mapping group is a mapping relation group between the server and the logical volume created by the cloud magnetic array; the server maps the first logical volume in the first mapping group to the server; and the server directly writes the obtained mirror image file in the first logical volume.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for creating a mirror image file in a logical volume, starting a virtual machine and a server. Background technique [0002] For various SAN (Storage Area Network and SAN Protocols, storage area network and its protocols) storage systems, cloud disks (such as logical volumes located in the cloud) can be used as system disks of virtual machines, and can be created in cloud disks Image file, so that VM (Virtual Machine, virtual machine) can be started from the image file, so as to achieve the purpose of rapid deployment and start of virtual machine, and can also save local resources, and it is safer and more reliable to use shared storage as the system disk of virtual machine. Flexible application. [0003] But, at present Openstack (a kind of open source cloud computing management platform project) common method of creating image file in the logical volume of the c...
