Basic Topology, High Availability Version: Host with Four Fibre Channel I/O Adapters
The non-high availability version of this topology connects a host or server to one or more
single-controller module disk arrays. This version provides no hardware redundancy and
does not protect against single points of controller module, Fibre Channel cable, host Fibre
Channel I/O adapter, or internal Ultra2 SCSI bus failure. If any of these components fail, the
disk array becomes unavailable and applications cannot continue to run. The disk array
remains unavailable until the failed hardware component is replaced. Applications can
continue to run after the failure of single disk modules within logical disk units (LUNs).
