Drive Addressing

This appendix illustrates the drive addressing for the disk enclosures. There are two drive numbering options:

•1 x 60 (one set of drives 1 through 60); (Figures B-1and B-3).

•2 x 30 (two sets of drives 1 through 30); (Figures B-2 and B-4) Figure B–1 1x60 Drive Layout Configuration
