Sun has announced the release of Sun Cluster 3.1. According to the company, key improvements include easier upgrades as well as tighter integration with Solaris 9.
In a statement, the company said the new release will improve on older versions by allowing administrators to upgrade to later releases of the product without having to shut down the entire cluster.
In addition, the company says it has integrated the product with the Solaris 9 Resource Manager for better performance in the case of a failover. In addition, Sun has integrated Sun Cluster 3.1 with the Sun Management Center, bringing SunPlex environments under the roof of existing management frameworks to ease the load on administrators dealing with systems in different locations.
The company also touted improved capabilities meant to allow better management of service levels and better handling of spikes in demand through integration with dynamic system domains and reconfiguration, and resource management controls.
Sun Cluster 3.1 also introduces five new agents: HA IBM WebSphere MQ; HA IBM WebSphere MQ Integrator; HA SAMBA; HA DHCP; and third-party IBM DB2-HA. All of the new agents support security hardening.
