*High availability principles fundamentals and best practices to enhance data center procedures and application availability *Sun Cluster 2.2 infrastructure architecture, supported components and data services APIs *Sun Cluster 2.2 implementation administration, databases, data service API script templates, low-end NFS-server implementation, etc. *Beyond Sun Cluster 2.2 technology overview of the new generation Sun Cluster 3.X product The explosive expansion of e-commerce and the ever-increasing dependency on computer services have created a global demand for server availability. This Sun BluePrints publication describes elements that affect availability and introduces best practices that promote good work practices. The information contained in this publication helps increase availability at the datacenter level or at the single- server level. The Sun Cluster 2.2 technology is explained in detail-the architecture, applications (including databases), low-end NFS servers, as well as maintenance requirements. This information can help customers apply specific product solutions to satisfy the most stringent high-availability more
