Figure 19. One single-controller DS3200 and multiple single-ESM storage expansion enclosures

Note: In storage expansion enclosures that are connected to a dual-controller storage subsystem, you must install the optional second ESM to support dual redundant drive paths, and must use one of the dual-controller topologies that are described in this section.
