Edgecore Networks' open networking data center switches – two AS6700-32X
spine switches and four AS5710-54X
leaf switches – are used in ClouldLabs, running Big Switch Networks' Big Cloud Fabric (BCF) as the validation with OpenStack in 2015. This project validated the ease of deployment and full functionality of the BCF P+V solution in a customer lab environment with Edgecore's open networking TOR and spine switches.
CloudLabs is an initiative within Ciii chartered with streamlining the efforts to service its customers' cloud related needs. With the emergence of scale-out computing workloads for e-commerce, big data analytics, and private cloud, Ciii customers are demanding integrated solutions encompassing rack-scale hardware with integrated software stack. In many cases, the complete stack is a converged infrastructure that includes optimized hardware with software architectures that solve specific workload requirements around speed, performance, power, and cost. The trend of disaggregation and open source software proliferation has led to the emergence of new scale-out blueprints over the last decade that has dramatically changed the infrastructure landscape.
CloudLabs provides engineering and design services to optimize such rack level solutions with emphasis on multivendor equipment integration. CloudLabs enables customers to accelerate a spectrum of cloud, converged infrastructure, and data center strategies. For this purpose, CloudLabs have created a customer showcase staging area running a live multi-rack cloud instance on hardware developed within Flex. This staging lab facilitates our customers and partners to deploy the latest technologies and allow for faster diffusion of technologies in a controlled environment, identifying value propositions for the end customer. It also provides our customers access to a sandbox environment that can be leveraged to test the performance of their workloads and evaluate the solution capabilities.
Application Diagram / Lab Environment
Clos Network Topology
The network topology deployed at CloudLabs is a leaf-spine topology, where all devices are exactly the same number of segments away from each other, and contain a predictable and consistent amount of latency. Every physical leaf switch is interconnected with every spine switch (full-mesh). This demonstrates the Clos network topology. Leaf switches in the same rack are connected together with two links (10-GbE ports) to create a leaf group. Dual links increase the available bandwidth and provide link-level redundancy. The 10-GbE dual-bonded links from the compute nodes are connected to both ToR leaf switches in the same rack. The 10-GbE dual-bonded links from the Big Cloud Fabric Controller nodes are connected to both ToR leaf switches in the same rack for vSwitch management.
Why Edgecore Networks
As the first OCP-approved 10G/40G switches, the Edgecore bare-metal switches, AS5710-54X
, with their pre-loaded ONIE (Open Network Installation Environment) enable different network operating systems to easily run on top of the Edgecore hardware, while ECS4110-52T
48-port layer 2 GE management switches run as administration switches for BCF controllers and Leaf/Spine switches.
