EXP100 loop redundancy
The EXP100 provides redundant loop support when the second ESM is configured,
and when both loops (called A and B) are connected to a DS4000 that supports
redundant loops. If a cable or SFP module fails on drive loop A, drive loop B
provides redundancy, which is an alternate path to your disk drives.
Figure 41 on page 57 shows a redundant loop that you might create with a DS4300
storage subsystem and four EXP100s. The numbers provided in Figure 41 on page
57 show the order in which cables should be attached.
