Implementation

Normally, two System Service Processors were used per platform. One was configured as ''Main'' and the other as ''Spare''. Only the SSP in the role of ''Main'' could control the platform at any given time. Failover between ''Main'' and ''Spare'' was performed automatically by the SSP software.

Supported hardware platforms

The following systems were supported for use as System Service Processors: * Sun SPARCstation 5 * Sun Ultra 5 * Sun Enterprise 250 * Sun Netra T1
