This section contains information about initially setting up a Intel RAID High Availability Storage
configuration with one or two JBODs. It also explains how to add a second JBOD to a single-JBOD
configuration without interrupting service on the configuration.
The following figure shows how to set up a two-controller-node configuration with a single JBOD
enclosure.

The cross-connections between the controllers provide redundant paths that safeguard against ESM
failure.
To retain consistent device reporting, the corresponding port numbers for both controllers must be
connected to a common enclosure ESM. In this example, port 0 to port 3 of both controllers are connected

The following figure shows how to set up a two-controller-node configuration with two JBOD enclosures.
