Abstract
The present invention is an apparatus and method for using the dual port feature of Fibre Channel to allow multiple computer hosts to simultaneously access a cluster of memory units that are Fibre Channel arbitrated. Typical multiple host access schemes require an expensive Fibre Channel switch and do not allow simultaneous accessing. The dual port feature of Fibre Channel devices provides for fault tolerance and redundancy, but can be used for the present invention.
