recommended that you cable storage expansion enclosures of same type
together to make maintenance and troubleshooting easier in the event of failure.
you must group the enclosures together by model types. The EXP100 group
must be on either side of the EXP710 and EXP810 group. The reason for this
grouping requirement is because the controller firmware considers EXP810s and
EXP710s to be the same enclosure type (switched disk expansion unit type that
have an ESM-embedded fibre channel loop switch) even though they are actually
different models. These two storage expansion enclosure models must be
grouped together if they are contained within a drive channel/loop. When mixing
EX100, EXP710 and EXP810 in the same redundant drive loop pair, the
recommended storage expansion enclosure grouping is group of EXP710s,
followed by group of EXP810s, and followed by group of EXP100s.
v
The EXP810 enclosure speed switch must be set to 2 Gbps when connecting to
DS4300 or DS4500 storage subsystems or EXP100 and EXP710 storage
expansion enclosures.
v
The controller drive ports of the DS4000 storage subsystem controllers must
always be connected to the ports labeled 1B in both right and left ESMs of the
EXP810s in the redundant drive channel/loop pair that is connected to the
DS4000 storage subsystem. (Figure 34 on page 55 shows the location of the
ports.)
