The two-node <strong>Oracle</strong> <strong>11g</strong> RAC cluster nodes <strong>and</strong> the proxy node were cabled <strong>and</strong><br />
zoned as shown in the following image. Each node contained two dual-port HBAs.<br />
The four ports were used to connect the nodes to the CX4-960. CLARiiON best<br />
practice dictates that single initiator soft zoning is used. Each HBA is zoned to both<br />
storage processors. This configuration offers the highest level of protection <strong>and</strong> may<br />
also offer higher per<strong>for</strong>mance. It entails the use of full-feature PowerPath software.<br />
In this configuration, there are multiple HBAs connected to the host; there<strong>for</strong>e, there<br />
are redundant paths to each storage processor. There is no single point of failure.<br />
Data availability is ensured in event of an HBA, cable, switch, or storage processor<br />
failure. Since there are multiple paths per storage processor, this configuration<br />
benefits from the PowerPath load-balancing feature <strong>and</strong> thus provides additional<br />
per<strong>for</strong>mance.<br />
The connectivity diagram below shows the two-node <strong>Oracle</strong> <strong>11g</strong> RAC cluster nodes.<br />
