DS3500 storage subsystem drive cabling topologies
This section describes the following preferred cabling topologies for cabling
expansion enclosures to the DS3500 storage subsystem:
v
“One single-controller DS3500 and one or more expansion enclosures”
v
“One dual-controller DS3500 and one expansion enclosure”
v
“One dual-controller DS3500 and two expansion enclosures” on page 43
v
“One dual-controller DS3500 and up to eight expansion enclosures” on page 43
If one of these examples is suitable for your hardware and application, complete the
cabling connections as shown in the illustrations. If you have hardware other than
what is shown in these examples to include in your topology, use these examples
as a starting point for creating your specific topology.
Note:
In expansion enclosures that are connected to a dual-controller storage
subsystem, you must install the optional second ESM to support dual
redundant drive paths.
One single-controller DS3500 and one or more expansion enclosures:
To
cable one single-controller DS3500 to one or more single-ESM expansion
enclosures, connect them as shown in Figure 36.
Note:
In 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.
One dual-controller DS3500 and one expansion enclosure:
To cable one
dual-controller DS3500 to one expansion enclosure, connect them as shown in
Figure 36. One single-controller DS3500 and multiple single-ESM expansion enclosures
