Edge Network Reference Architecture
This appendix includes the following topic:
•  Edge network card interfaces
Edge network card interfaces
For deployments with Edge appliances, the first PCIe slot is always populated with a 4-port bypass network interface card (NIC) as standard. This NIC is used by the RiOS node as two in-path interfaces (inpath1_0 and inpath1_1) for WAN optimization. Depending on the Edge appliance model, there can be a further 1 to 5 PCIe slots available for additional multiple port NICs. Any additional multiple port NICs that you purchase and install must be specified for bypass or data at the time of ordering.
The following table summarizes the deployment options for Edge models.

In which:
•  in-path - Bypass NIC used by the RiOS node for WAN optimization traffic.
•  storage - Multiple port data NIC used by the RiOS node, enabling iSCSI access for storage traffic to and from servers external to the Edge, or as additional heartbeat interfaces with Edge HA deployment.
•  data - Multiple port data NIC used by the hypervisor node, enabling LAN access for hypervisor node traffic.
Note: You can use a multiple port data NIC for storage or data. It just depends on the slot the NIC is installed in.
