The image rac1.gif shows a sample RAC configuration. The image is split into three sections:

• The top section, labeled "Clients," shows a group of client computers connected to the network.
• The middle section, labeled "Middle Tier," shows a set of computers running application servers.
• The bottom section, labeled "Database Tier," shows a group of Database Server nodes which form the Shared Cache. These Database Server nodes are connected to a Shared Disk Database. A caption on this tier reads, "Clustered Database Server Nodes are connected via a high speed, low latency Interconnect"
