Document potential Cloud Native SR-IOV Use cases

[taylor]

Goal: Implement clean room 100% open source SR-IOV use cases and create cloud native versions

• [ ] Create an overview of the goal
• [ ] List some real world use cases

Goal

PoC for NSM plus SR-IOV and other offload cards spanning multiple nodes

Use cases

• Cloud interconnection at Colo
• Edge sites where latency and security are paramount
• Multi-tenant environments
• Service chains spanning multiple nodes; manage clusters, not nodes:)

Why SR-IOV?

• Switching at ToR switch for maximum visibility/security in a multi-tenant environment
• Service chain will likely span multiple nodes; service chains could be up to 4-5 CNFs
• Accelerating the data plane throughput for high packet throughput and low processing latency
• Direct communication with the NIC device allows for close to “bare-metal” performance
• Leveraging of NIC accelerators and offloads per workload
• Deterministic performance at the edge where there will be limited compute capacity

Questions

• Can NSM and multus be used together? It appears that the Intel SR-IOV device plugin must be used with multus
• Can the X710 dual-port cards be used on packet? Or only X710 quad port card?
