Figure 36 shows an example of a DS5100/DS5300 storage subsystem that is
cabled to two EXP5000s using a non-trunking cabling scheme. P8 and P6 of
controller A are connected to EXP5000 ESM A drive channel ports label 1B.
Similarly, the storage subsystem drive ports P1 and P3 of controller B are
connected to the EXP5000 ESM B drive channel ports labeled 1B.
Figure 37 shows an example of a DS5100/DS5300 subsystem that is cabled to two
EXP5060s using a non-trunking cabling scheme. The storage subsystem drive ports
P8 and P6 of controller A are connected to EXP5060 ESM A drive channel ports
label 1B. Similarly, the storage subsystem drive ports P1 and P3 of controller B are
connected to the EXP5060 ESM B drive channel ports labeled 1B.
The EXP5060 storage expansion enclosure requires firmware version 7.60.13.05, or
higher.
Port 1A of the EXP5000 or EXP5060 ESMs are used to connect more than one
EXP5000 or EXP5060 enclosure behind a storage subsystem controller drive port.
Figure 38 on page 63 shows an example of a DS5100/DS5300 subsystem that is
cabled to two EXP5000s behind the same DS5100/DS5300 drive channel port
using a non-trunking cabling scheme.
