OCP has the mission to “design and enable the delivery of the most efficient server, storage and data center hardware designs for scalable computing”.
OCP had its global 2019 summit recently. Some interesting trends on hyperscale networks are discussed here and here with the use of F16 fabric network with its a focus on higher bandwidth but also performance at the right cost instead of at any cost. The heart of this new F16 fabric is the Minipack switch, with contribution from Arista which Facebook says will consume 50 percent less power and space than the Backpack switch it replaces in the network. It is a 128x100Gb switch and uses a Broadcom Tomahawk-3 Asic. Quote: “a path from a rack in one building to a rack in another building over Fabric Aggregator was as many as 24 hops long before. With F16, same-fabric network paths are always the best case of six hops, and building-to-building flows always take eight hops. This results in half the number of intrafabric network hops and one-third the number of interfabric network hops between servers.”
Intel announced an industry collaboration around Platform Root of Trust at the Open Compute Project 2019 summit.
There’s a talk on Stratum and the use of P4 and Switch Abstraction Interface (SAI) for SDN, by Open Networking Foundation (ONF) and Google. Tencent has a use case for disaggregating their monolithic network into a modular switch with a network of controllers instead of a single controller.
Smaller data centers at the edge is another trend.
