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.
