Abstract

A method of manufacturing a computer includes creating a reference two-disk software RAID pair, the software RAID pair having desired partitions mirrored by an operating system. The method also includes extracting a master image from one disk of the reference disk pair, performing a difference comparison of partitions of a target disk of the reference disk pair against the master image and obtaining a collection of differences. The method further includes writing the master image to each disk of a disk set in the computer being manufactured and applying the collection of differences to a target disk of the disk set.

Claims

1. A method of manufacturing a computer comprising:

creating a reference two-disk software RAID pair, the software RAID pair having desired partitions mirrored by an operating system;

extracting a master image from one disk of the reference disk pair;

performing a difference comparison of partitions of a target disk of the reference disk pair against the master image and obtaining a collection of differences;

writing the master image to each disk of a disk set in a computer being manufactured; and

applying the collection of differences to a target disk of the disk set in the computer being manufactured.

2. The method of claim 1, wherein the reference two-disk software RAID pair includes a software RAID1 mirror pair.

3. The method of claim 2, further wherein the software RAID1 mirror pair includes partitions mirrored by a server operating system.

4. The method of claim 3, wherein the operating system is one selected from the group consisting of Linux, Windows NT™

, and Windows 2000™

.

5. The method of claim 1, wherein performing the difference comparison and obtaining the collection of differences includes extracting locations and contents of blocks that are different between the disks of the reference pair.

6. The method of claim 5, further wherein applying the collection of differences includes applying the collection of differences block by block to the target disk in the computer being manufactured.

7. The method of claim 1, wherein writing the master image to each disk of the disk set in a computer being manufactured occurs during a preinstallation of software images to the disks.

8. The method of claim 1, wherein the master image is written to all disks of the disk set simultaneously.

9. A method of manufacturing a computer comprising:

creating a reference two-disk software RAID 1 mirror pair, the software RAID 1 mirror pair having desired partitions mirrored by an operating system;

extracting a master image from one disk of the reference disk pair;

performing a difference comparison of partitions of a target disk of the reference disk pair against the master image and obtaining a collection of differences, including extracting locations and contents of blocks that are different between the disks of the reference pair;

writing the master image to each disk of a disk set in a computer being manufactured; and

applying the collection of differences block by block to a target disk of said disk set in the computer being manufactured.

10. The method of claim 9, wherein the master image is written to all disks of the disk set simultaneously.

11. A computer system comprising:

a processor; and

a storage accessible by said processor, said storage including a software RAID mirror pair formed by;

creating a reference two-disk software RAID pair, the software RAID pair having desired partitions mirrored by an operating system,

extracting a master image from one disk of the reference disk pair,

performing a difference comparison of partitions of a target disk of the reference disk pair against the master image and obtaining a collection of differences,

writing the master image to each disk of a disk set in said computer, and

applying the collection of differences to a target disk of the disk set in said computer.

12. The computer system of claim 11, wherein the reference two-disk software RAID pair includes a software RAID1 mirror pair.

13. The computer system of claim 12, further wherein the software RAID1 mirror pair includes partitions mirrored by a server operating system.

14. The computer system of claim 13, wherein the operating system is one selected from the group consisting of Linux, Windows NT™

, and Windows 2000 ™

.

15. The computer system of claim 11, wherein performing the difference comparison and obtaining the collection of differences includes extracting locations and contents of blocks that are different between the disks of the reference pair.

16. The computer system of claim 15, further wherein applying the collection of differences includes applying the collection of differences block by block to the target disk in the computer being manufactured.

17. The computer system of claim 11, wherein writing the master image to each disk of the disk set in a computer being manufactured occurs during a preinstallation of software images to the disks.

18. The computer system of claim 11, wherein the master image is written to all disks of the disk set simultaneously.

19. A computer system comprising:

a processor; and

a storage accessible by said processor, said storage including a software RAID mirror pair formed by;

creating a reference two-disk software RAID1 mirror pair, the software RAID pair having desired partitions mirrored by an operating system,

extracting a master image from one disk of the reference disk pair,

performing a difference comparison of partitions of a target disk of the reference disk pair against the master image and obtaining a collection of differences, including extracting locations and contents of blocks that are different between the disks of the reference pair,

writing the master image to each disk of a disk set in said computer, and

applying the collection of differences block by block to a target disk of said disk set in said computer.

20. The computer system of claim 19, wherein the master image is written to all disks of the disk set simultaneously.
