The SUNW,clprivnet Sun Cluster private network driver is a STREAMS pseudo driver supporting Sun Cluster resident applications that use standard Solaris interfaces to communicate over the Sun Cluster private network. By striping data traffic over all links, this driver optimally utilizes the bandwidth of the private network while supporting highly available, software fault-tolerant communication.

The driver is supported by the character-special device /dev/clprivnet, but is reserved for Sun Cluster internal operation and the standard Solaris network utilities. This interface must not be directly used for general application communication.

The administration and configuration of the driver as a network interface is done completely by the Sun Cluster infrastructure internals.
