T
wo SDS 100 Storage Systems
Cabled to Dual RAID Controllers
To cable cluster nodes with dual RAID controllers to two
SDS 100 storage systems, connect the channel 0 connec-
tor of each RAID controller of the primary node (or the
first node) to the “A” connectors on the back of each stor-
age system, and connect the channel 0 connectors of the
secondary node’s RAID controllers to the “B” connectors
on each storage system (see Figure 2-3).
NOTE: On clusters with multiple SDS 100 storage sys-
tems, the channel 0 connectors of the two RAID
controllers must be connected to one storage system, and
the channel 1 connectors must be connected to the sec-
ond storage system. If the connections are ever removed,
you must reconnect the cables as they were connected
previously. To help ensure that the same storage system is
attached to the same channels, tagging or color-coding
the cables is recommended.
