2.10.1 Drive Location Rules

The FC60SS and FC60SS-XPN enclosure systems support two different types of disk

drive, SAS and SATA. In order to allow optimal configurations to be built, the following rules should be

observed:

1 Different drive types (i.e.SAS and SATA) cannot be mixed in the same column, i.e.

– Slots 1, 5, 9 = column 1

– Slots 2, 6, 10 = column 2

– Slots 3,7,11 = column 3

– Slots 4, 8, 12 = column 4

(see Table 2–2 for slot arrangement).

2 To achieve optimum performance drives should be populated in the following location sequence

– slots 2, 6 and 10 initially,

– followed by slots 3, 7, 11

– then slots 1, 5, 9

– and finally slots 4, 8, 12, i.e.
