Cabling Your RAID Enclosure

Figure 2-5. Cabling a Single Host (Single-HBA) Using Redundant Data Paths
Dual SAS In-Port Configurations
Figure 2-6 through Figure 2-12 show supported nonredundant and redundant cabling configurations to
MD3000 RAID controller modules with two SAS In port connectors. Each diagram shows the maximum
number of optional expansion enclosures attached.
Figure 2-6 shows how one, two, three, and four hosts can each be connected to a RAID controller module
nonredundantly. The RAID controller module is subsequently expanded to two more storage enclosures.
The hosts can share storage space but without redundant paths, if one path were to fail, the server on
that path would be disconnected from the storage array.
