Virtualization technologies provide a safe way to consolidate multiple applications on a single system. This paper introduces the zone cluster, a virtual cluster in which a Solaris™ OS Zone is configured as a virtual node. The zone cluster supports the consolidation of multiple cluster applications on a single cluster.
This paper addresses the following topics:
• "Cluster application consolidation" presents the forces driving consolidation.
• "Server virtualization technologies" provides an overview of Sun's virtualization technologies, with an emphasis on Solaris Zones.
• "Zone cluster overview" introduces the zone cluster and further identifies numerous use cases that demonstrate its utility.
• "Zone cluster design" describes the overall design of the zone cluster.
• "Administration overview" provides an overview of zone cluster administration.
• "Example zone cluster configuration" contains step-by-step instructions for an example zone cluster configuration.
• "Zone cluster administration" describes common zone cluster administrative tasks.

Dr. Ellard Roush is the Technical Lead for the Solaris Cluster Infrastructure Group. He is the architect for the zone clusters project. This is just one of many projects that have ranged across many areas, including: membership, upgrade technology, and cluster file systems. He earned the Ph.D. in Computer Science from University of Illinois at Urbana-Champaign and M.S. in Computer Science from Stanford University.
