Production network connections are shown in the following figures. Each leaf has one 100 GbE connection to each spine. Each Isilon node has one connection to each leaf on Rack 2. Connections from S5248F-ON leaf switches to Isilon nodes, PowerStore storage, and PowerEdge servers support either 10 GbE or 25 GbE. The examples in this guide use 10 GbE, and demonstrate breakout ports with SFS and OMNI.
Note: In this example, the two QSFP28-DD double density ports (2x 100 GbE interfaces per physical port), available on S5248F-ON switches, are used to create a 400 GbE VLTi. This configuration requires QSFP28-DD DAC cables or optics. On switches without QSFP28-DD ports, QSFP28 (100 GbE) or QSFP+ (40 GbE) ports are typically used for VLTi connections. The VLTi synchronizes L2 and L3 control-plane information across the two nodes. The VLTi is used for data traffic when there is a link failure that requires the VLTi to reach the destination. Dell Technologies recommends using at least two physical ports on each switch for the VLTi for redundancy and to provide additional bandwidth in the case of a failure.
The production network connection details for Rack 1 are shown in the following figure.
The production network connection details for Rack 2 are shown in the following figure.
