Sun Cluster 3.0 is the software backbone of Sun's clustered server environments, called SunPlex systems, said Jim Sangster, group marketing manager for Sun clusters.
Enhancements to Sun Cluster 3.0 include the ability to dynamically reconfigure a Sun Enterprise 10000 server within a cluster, removing and replacing processors, memory, and I/O devices on the fly, Sangster said.
Sun Cluster 3.0 "supports the dynamic addition and removal of processing components in an active, running cluster," Sangster said. "This decreases both planned and unplanned downtime."
Sun will extend this dynamic reconfiguration ability beyond the Enterprise 10000 server in later upgrades of Sun Cluster 3.0. Dynamic reconfiguration of SunFire mid-range and high-end servers from model 3800 through the Sun F15000 will be available from Sun Cluster 3.0 by the end of 2002, Sangster said.
Enhanced security for Apache Web Server, iPlanet Web Server, and iPlanet Mail Server was also added to the latest version of Sun Cluster 3.0. The security upgrades are meant to help prevent hacker intrusions or denial of service attacks, according to Sun.
An improved SunPlex Agent Builder is also now part of Sun Cluster 3.0. The Agent Builder helps users deploy application services faster in clustered server environments by generating pre-compiled agent binaries that can be installed without added code from developers, according to Sun.
