Creating a Merged Fabric

Oracle SDN is supported in a merged IB fabric. A merged fabric occurs when Oracle Fabric Interconnects are connected so that they both act as one unified system (and IB fabric) instead of two individual systems.

How you create the merged fabric differs depending on type of switch environment you have:

• New deployment, which is a new shipment of switches that have not yet been configured in the fabric.

• Existing stand-alone, which occurs when one or more existing QDR Oracle Fabric Interconnects are already installed and operating as two independent systems, each with its own IB fabric. In this environment, you need to complete additional steps before and after cabling the switches together.

Typically, these two types of switch environment are mutually exclusive.

Environment Description Links New deployment 1. Install and power on the switches. Refer to the appropriate installation manual for your switch or Oracle Fabric Interconnect 2. Connect the cables to create a merged EDR or QDR fabric. Connecting Cables (EDR) Connecting Cables (QDR) Existing stand-alone environment 1. For QDR fabrics, shut down the IB subnet manager and remove the IB LID table. Preparing to Merge an IB Fabric (QDR) 2. For QDR fabrics, connect the cables to create a merged QDR fabric.
