DS4000 storage expansion enclosure models can be mixed in the pair of redundant
drive loops. Table 14 on page 64 shows whether an existing storage expansion
enclosure within a DS4500 redundant drive loop can support the addition of new
storage expansion enclosures of another model type. Table 15 on page 65 lists
possible storage expansion enclosure intermix combinations between 10-drive and
14-drive storage expansion enclosures or between 14-drive and 16-drive storage
expansion enclosures, as well as total number of drives for each combination.
