Guidelines for allocating and loading Drives

• A Drive Pair or Drive Pairs must be installed together and must be of the same capacity, speed, and
type. Never install an uneven number of Drives of one type within a single enclosure.
• While making sure to load Drives in pairs of the same Drive type, try to distribute the same number of
Drives and Drive types in all enclosures. An even distribution may not always be possible.
• Different Drive types can be loaded next to each other in the same enclosure, but load all the Drives of
one Drive type before loading Drives of a different Drive type.
