Figure 9 Two-Controller-Node Configuration with Dual JBODs
The top-down/ bottom-up cabling approach shown in this figure has the following benefits:
The cross-connections between controllers and ESMs safeguard against the complete disconnection
of a server from the drive enclosure.
Continued access to drives is assured in the event of a complete drive enclosure failure or removal.
Additional expansion drive enclosures can be hot-added without disrupting service, as shown in
Figure 9.
The following figure shows an incorrectly cabled configuration with two disk enclosures.
