<title>Sun Cluster System</title>
<h1>Sun Cluster System</h1>

A Sun Cluster system is a highly available
configuration of up to four
    <a href="sc/node">nodes</a>
running the Sun Cluster 
software.  The nodes are connected by two private
    <a href="sc/private_net">interconnect networks</a>
and the shared data is stored on a multi-ported
storage subsystem. Each element of the storage
subsystem is accessible by at least two nodes via direct
    <a href="sc/fibre">Fiber Channel</a>
optical links or SCSI cables.
