Abstract

Provided is a deployment method for a server system that includes a storage system having logical disks where disk images are stored and plural servers connected to the storage system via a storage network, the method including the step of causing a deploy management module to copy the logical disks which store the disk images to a free area of the storage system before a deployment command is received. According to this invention, disk images are quickly deployed to servers.

Claims

1. A deployment method for a server system that comprises a storage system having storage areas storing disk images to be masters and a plurality of servers connected to the storage system via a network, the deployment method comprising the steps of:

holding, by a deploy management module, storage area information including capacities and priorities of storage areas where the disk images are copied in order to manage the copied storage areas;

copying, by the deploy management module, the storage areas storing the disk images to a free area of the storage system repeatedly to make a plurality of copies of the storage areas;

determining, by the deploy management module, whether the free area of the storage system includes storage areas where disk images designated to be deployed by the deployment command have been copied, with reference to the storage area information; and

copying, by the deploy management module, the storage areas storing the disk images designated to be deployed by the deployment command in the free area of the storage system if the free area of the storage system does not include the storage areas.

2. The deployment method according to claim 1, further comprising the steps of:

receiving, by the deploy management module, a deployment command;

setting, by the deploy management module, paths between the servers designated by the deployment command in which the disk images are to be deployed and the storage areas where the disk images designated to be deployed by the deployment command have been copied, upon receipt of the deployment command; and

setting server-specific information to the storage areas where the disk images have been copied.

3. The deployment method according to claim 1, further comprising the steps of:

obtaining, by the deploy management module, usage amounts of resources of the plurality of servers; and

changing the number of copies of the disk images depending on the usage amount of the resources.

4. The deployment method according to claim 1, wherein the free area is idle resources.

5. A server system comprising:

a storage system having storage areas storing disk images to be masters;

a plurality of servers connected to the storage system via a network; and

a deploy management module for deploying the disk images to the plurality of servers,

wherein the deploy management module holds storage area information including capacities and priorities of storage areas where the disk images are copied in order to manage the copied storage areas, copies the storage areas storing the disk images to a free area of the storage system repeatedly to make a plurality of copies of the storage areas, determines whether the free area of the storage system includes storage areas where disk images designated to be deployed by the deployment command have been copied with reference to the storage area information, and, if the free area of the storage system does not include the storage areas, copies the storage areas storing the disk images designated to be deployed by the deployment command in the free area of the storage system.

6. The server system according to claim 5, wherein, upon receipt of a deployment command, the deploy management module sets paths between the servers designated by the deployment command in which the disk images are to be deployed and the storage areas where the disk images designated to be deployed by the deployment command have been copied upon receipt of the deployment command, and sets server-specific information to the storage areas where the disk images have been copied.

7. The server system according to claim 5, wherein, the deploy management module obtains usage amounts of resources of the plurality of servers and changes the number of copies of the disk images depending on the usage amounts of the resources.

8. The server system according to claim 5, wherein the free area is idle resources.

9. A medium storing a program for deploying disk images to a plurality of servers in a server system that comprises a storage system having storage areas storing the disk images to be masters and the plurality of servers connected to the storage system via a network, the program causing a computer to execute the steps of:

holding storage area information including capacities and priorities of storage areas where the disk images are copied in order to manage the copied storage areas;

copying the storage areas storing the disk images to a free area of the storage system repeatedly to make a plurality of copies of the storage areas;

determining whether the free area of the storage system includes storage areas where disk images designated to be deployed by the deployment command have been copied, with reference to the storage area information; and

copying the storage areas storing the disk images designated to be deployed by the deployment command in the free area of the storage system if the free area of the storage system does not include the storage areas.

10. The medium storing the program according to claim 9, wherein the program further causes the computer to execute the steps of:

receiving a deployment command;

setting paths between the servers designated by the deployment command in which the disk images are to be deployed and the storage areas where the disk images designated to be deployed by the deployment command have been copied, upon receipt of the deployment command; and

setting server-specific information to the storage areas where the disk images have been copied.

11. The medium storing the program according to claim 9, wherein the program further causes the computer to execute the steps of:

obtaining usage amounts of resources of the plurality of servers; and

changing the number of copies of the disk images depending on the usage amounts of the resources.
