Non-Redundant DAS Configurations

Note – Using single connections between Sun StorEdge 3510 SCSI arrays and servers creates single points of failure (SPOF) that can cause interruptions in the event a connection becomes unreliable or fails. This is not a recommended configuration unless host-based mirroring is utilized to protect against single points of failure.
