Cabling Your Enclosure
You can cable your enclosure in either a unified-mode configuration or in a
split-mode configuration.
• In a unified-mode configuration your enclosure is connected to one host,
for example, a server with a controller card. Your enclosure can be one of
up to four enclosures daisy-chained to a single port on the controller card
in your host server. The enclosure can also be connected in a redundant
path mode with two connections to single host server. See Figure 2-2 and
Figure 2-3 for cabling diagrams of a unified mode configuration.
• In a split-mode configuration, your enclosure is connected to two separate
controller cards. The controller cards may reside in the same server or in
two different servers. The enclosure bus is logically split in half where the
first half of the enclosure is managed by one controller and the second half
of the enclosure is managed by the second controller. Table 2-1 lists the
