Hard Drive Numbering

The front section of the S12E enclosure houses twelve (12) hard
drives in a 4x3 configuration. (See Figure 1-3) When viewed from the
front, the drive bays (slots) are numbered 1 to 12 from left to right
and then from top to bottom.
Tray numbering sequence is important if one disk drive fails and
needs to be replaced. Replacing a wrong drive can fatally fail a
RAID3/5 array. Failing three drives destroys a RAID6 array.
