Designing Enterprise Solutions with Sun™ Cluster 3.0

System Features

This section discusses the topologies available for various business requirements and applications, global features (global devices, global file service, global networking service), cluster private interconnects, and cluster configuration control.

Storage Topologies

Currently, Sun Cluster 3.0 supports three types of storage topology—clustered pairs (FIGURE 3-5), N+1 (FIGURE 3-6), and pair+M (FIGURE 3-7). These are equivalent when only two nodes are considered. The following sections describe these topologies and their advantages and disadvantages for application deployment.
