Flash configurations
Flash module RAID configurations are similar to drive RAID configurations,
but with smaller numbers. The flash chassis holds only 48 drives, while the
drive chassis holds either 80 LFF or 128 SFF drives.
Each flash box is divided into two logical units. The LUs are numbered
vertically in the FBX starting with the lower logical units and then the upper
logical units. The FMDs are numbered 0 through 5 in each logical unit. The
following figure shows the numbering sequence.
