Production network connections are shown in the following figure. Each leaf has one 100 GbE connection to each spine. Each Isilon node has one connection to each leaf. Connections from S5200-series leaf switches to Isilon nodes and servers support either 10 GbE or 25 GbE. The example in this guide, 10 GbE is used to 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 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 EMC 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.
