Quick deployment method
First Claim
1. A deployment method for a server system that comprises a storage system having storage areas where disk images containing operating systems are stored and plural servers connected to the storage system via a storage network, the method comprising the steps of:
- causing a deploy management module, having a storage area management table to manage capacity and priority of copies of the storage area which store the disk image, to copy each disk image stored in at least one of a plurality of storage areas to a free area of the storage system before a deployment command, which requests deployment, is received;
causing the deploy management module to receive the deployment command;
causing the deploy management module to consult, upon reception of the deployment command, the storage area management table in order to judge whether or not the copies of the storage area that store disk images to be deployed by the command are in a free area of the storage system;
causing the deploy management module to copy the disk image to be deployed by the command to the area of the storage system when the copies of the disk image are not in the free area of the storage system;
causing the deploy management module to consult, when there is a shortage of the free area of the storage system, the storage area management table in order to select a disk image copy of low priority; and
causing the deploy management module to delete the selected disk image copy.

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.

8. A server system comprising:
-
a storage system having a storage area where disk images containing operating systems are stored; a plurality of servers connected to the storage system via a storage area network; and a deploy management module to deploy the disk images in the servers, wherein the deploy management module comprises; a communication module which receives a deployment command, and a storage area management module, having a storage area management table to manage capacity and priority of copies of the storage areas which store disk images, which copies the storage areas so that a copy of each disk image is stored in at least one of a plurality of storage areas to a free area of the storage system before a deployment command, which requests deployment, is received, wherein the storage area management module consults, upon reception of the deployment command, the storage area management table in order to judge whether or not copies of the storage areas that store disk images to be deployed by the command are in a free area of the storage system, and the storage area management module copies the storage area that store the disk images to be deployed by the command to the free area of the storage system when copies of the storage area are not in the free area of the storage system, wherein the storage area management module consults, when there is a shortage of the free area of the storage system, the storage area management table in order to select a storage area copy of low priority, and the storage area management module deletes the selected storage area copy. - View Dependent Claims (9, 12, 13)
