Connecting Direct Attach Configurations
This section explains how to connect the controller enclosure directly to data hosts.
It shows configurations that support high availability and high performance, and
notes when host port interconnects must be enabled.
The controller enclosure has four host connections, two per controller. Connect FC
cables from host ports on each controller to FC HBAs on data hosts, as shown in the
following figures. To maintain redundancy, connect each data host to both
controller A and controller B.
Caution – Fiber optic cables are fragile. Do not bend, twist, fold, pinch, or step on
the fiber optic cables. Doing so can degrade performance or render data unavailable.
Note – For clarity, the schematic illustrations of the controllers shown in this
section show only relevant details such as host ports. For detailed illustrations
showing all components, see “Hardware Components and LEDs” on page 13.
Figure 3-1 shows the preferred redundant configuration. This configuration requires
that host port interconnects are enabled as described in “Configuring Host Ports” on
page 55.
