4. Intermixing enclosures with trunked and non-trunked cabling in the same
storage subsystem is supported.
5. See “Drive-side trunking cabling” on page 69 and review the rules and
considerations.
6. Do not cable the EXP5060 storage expansion enclosures in a cascading
scheme unless all drive channel ports are used to support the additional
EXP5060s.
7. Connect the EXP5060 and EXP5000/EXP810 storage expansion enclosures in
separate drive channels in each controller to enable drive-side trunking with the
EXP5060 storage expansion enclosure.
DS5100 and DS5300 drive cabling topologies
The following sections provide preferred cabling topologies for cabling storage
expansion enclosures to the DS5100 and DS5300. Each example provides
redundant paths to the drives. If one of these examples is suitable for your
hardware and application, complete the cabling connections as described in the
tables. If you have hardware to include in your topology other than what is shown in
these examples, use the examples as a starting point for creating your specific
topology.
Attention:
For the maximum number of storage expansion enclosures supported
per redundant drive channel pair, see Table 3 on page 9.
If you are using fiber-optic cables, install SFP modules into the ports that will
receive the cables before installing the cables.
Figure 49 on page 78 and Figure 50 on page 79 show the locations of controllers A
and B, the single-ported Fibre Channel host channels, single-ported iSCSI host
channels, Ethernet ports, and dual-ported drive channels, at the back of the
DS5100 and DS5300.
