Two 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).

ultra-high density connector

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.
