Drive location rules
The E-842R storage enclosure supports two different types of disk drives, SAS and SATA. In order
to allow optimal configurations to be built, the following rules should be observed:
Different drive types cannot be mixed in the same column.
• Slots 1, 5, 9 = column 1
• Slots 2, 6, 10 = column 2
• Slots 3, 7, 11 = column 3
• Slots 4, 8, 12 = column 4
To achieve optimum performance, drives should be populated in the following sequence:
• Initially—Slots 2, 6, and 10
• Then—Slots 3, 7, and 11
• Then—Slots 1, 5, and 9
• Then—Slots 4, 8, and 12
