Business and application requirements have pushed web titans like FaceBook, Google, Microsoft and Amazon to innovative next gen data center designs that can meet the processing, networking and storage capacity required to serve millions to billions of users. At the networking layer, in addition to network link speeds increasing from 10Gbps to 40Gbps to 100Gbps, we are also seeing significant topology design changes. Large data centers are moving from traditional L2-based fat tree architectures with 3-tiers of access, aggregation and core layers into L3 ECMP-based multi-stage Clos networks that maximize link utilization and simplify application workload placement.
Along with that shift, SDxCentral research has observed that next gen data center networks focus more on software-centric controls (SDN). In addition, we’re seeing a shift towards disaggregation of networking devices (separating the constituent components), merchant silicon and white boxes in select verticals. Key success factors for building next gen data center networks include modularization and standardization of the fabric, ensuring support for virtualization and containers, adding programmability and automation as well as ensuring visibility to facilitate troubleshooting.
On the data center networking stack, the next gen data center network is no longer confined to the physical fabric but expands into cross-data center interconnects (DCI) and into accelerator NICs and virtual switches on the servers, with innovation happening across all these domains.
