However, based on your existing storage expansion enclosure configuration if it is
not possible to separate EXP710s and EXP810s in separate drive loops, it is
recommended that you group the storage expansion enclosures by model type
behind each controller drive port as shown in Figure 36. Note that the first group of
storage expansion enclosures (denoted in the graphic as �1�) is connected to drive
port 4 of controller A and drive port 1 of controller B. Also note that within the first
group, the three EXP810s are grouped together and then connected to the
EXP710.
