Unicycle SR-IOV Validation Servers

Verification was based on a Build Server VM and four identical Dell 740XD servers for the Regional Controller and three Unicycle nodes.

Unicycle SR-IOV Validation Networking

The diagram below shows the physical and L2 connectivity, the IP subnet plan, host and iDRAC addressing used in the validation.

The Unicycle deployment does not configure the networking subsystem thus the choice of switch subsystem components is not restricted to those shown and they can be replaced with devices offering equivalent functionality.

Unicycle SR-IOV Validation IP/VLAN Plan

Below is the detailed network and IP address plan

Unicycle SR-IOV BGP Plan

The three unicycle nodes automatically peer with an external fabric BGP speaker using eBGP. The calico nodes do not peer using an internal iBGP mesh.

Unicycle SR-IOV LAG Details

The RC and Unicycle genesis nodes boot via VLAN tagged 'host' interface which is pre-provisioned on the QFX switches with LAG bonding. Since booting occurs before the linux kernel can bring up its LAC-P signalling the QFX switches must be configured to pass traffic on their primary (first) link before the LAG bundle is up.
