Abstract

A system for factory installation of software that configures the storage resources in one or more file servers as a “cache.” The factory installation system includes at least one file server coupled to a storage management engine (SME) which is coupled to a library server. A target customer system being loaded with software is coupled to the file servers and library server. The library server will have sufficient storage capacity to maintain all of the software that may be requested by a target customer system. The storage management engine will determine which software programs included on the file server memory have been the least recently used and delete those files, thus causing the remaining files on the server memory to be the most recently used. When a target customer computer is being loaded, a request is first made to the file severs for the desired software. If the desired programs are located on the file servers, then a download to the customer computer is implemented. However, if the requested software is not present, the customer computer then sends a request to the library server for the desired software and a download from the library server to the customer computer occurs. When the target customer system requests the file from the library server, the request is logged in a directory in the library server. Periodically, the SME will read the logged requests and then update the file server memories with software which has been requested by the customer computers.

means for deleting only the software files from said file server having a date older than said predetermined date which are stored on said library server.

12. A method for installing software, comprising:

storing, on at least one file server, a first set of most recently used software files;

storing, on a library server, said first set of software files and a second set of least recently used software files;

installing installation software on a target computer;

loading the target computer with a software file from said file server in response to said software file being in said first set of software files;

connecting the target computer and the library server to a storage management engine;

using the installation software to retrieve available files from the file server and to search the library server after searching the file server for a specific file;

loading said target computer with said software file from said library server in response to said software file being in said second set of software files; and

in response to loading said target computer with said software file from said library server, adding the software file from the library server to said first set of software files on the file server.

13. A method according to claim 12 further comprising maintaining, by a control system, said first set of most recently used software files on said file server.

14. A method according to claim 13 wherein said maintaining comprises:

storing, in a directory in said file server, a date when each software file in said first set of software files is accessed by said target computer;

reading said date in said directory; and

deleting, from said first set of software files stored on said file server, the software files having a date older than a predetermined date.

15. A method according to claim 14 wherein said maintaining further comprises:
