Overview of Scalable Topology

The scalable cluster topology allows connectivity of up to four nodes to a single storage array. Note the following considerations for this topology at this time:

• All nodes must have the Oracle Parallel Server/Real Application Clusters (OPS/RAC) software installed. For information about installing and using OPS/RAC in a cluster, see the Sun Cluster 3.0 12/01 Data Services Installation and Configuration Guide.

• The storage arrays supported with this cluster topology at this time are the Sun StorEdge T3/T3+ array (single-controller configuration) and the Sun StorEdge 9900 Series arrays.
