Why are customers interested in changing Status Quo?

Shared & virtualized infrastructure

Attribute Servers Networking

Pro visio ning tim e Minutes Days / weeks

Co st Co st- effective Expensive

Disaggregatio ni Yes No t really

Managem ent Easy / sim ple Co m plex / hard

HW Abstractio n Yes (e .g. VMware ESX) No ne / prim itive

Customers are looking for • Programmability & automation - for innovation & agility • Networking independent of HW, locat ion & topology – for flexibility • Open – for lower CAPEX • Simplify IT – for lower OPEX

Recent Facebook announcem ent Validates disaggregation m odel

“We’re big be lievers in the value of disaggregat ion – o f breaking down traditional data center techno logies into the ir co re com ponents so we can build new system s that are more flexible, more scalable, and more

efficient .” - Facebook

• Control-plane Service is middleware infrastructure which provides DC-API (Data-centric API) to all the applications. Also provides State Storage.

• DC-API used by all software modules – primarily to configure & monitor Switching ASIC functionality, but not limited to it.

• Control-Plane adapter is essentially the Switch Driver - participates in Data-centric API, and invokes the switch-silicon SDK.

• Switching SDK exposes networking abstractions in the SDK layer
