Architect a Massively Scalable Data Center for big data and web 2.0 applications
A Cisco Massively Scalable Data Center (MSDC) is a collection of design tenets realized in a lab architecture. The overall architecture builds a scalable Layer 3 data center fabric over a three-stage Clos topology. The architecture is deployed to enable horizontally distributed applications, such as those found in warehouse-scale, hyperscale, and Web 3.0 environments. These applications generate workloads that require symmetric bisectional bandwidth between any computing or storage nodes attached to the network.
These applications are deployed on a cluster that is expected to scale up and down from hundreds of nodes to tens of thousands of nodes in order to serve millions of concurrent connections from clients. To support the elasticity in the control plane, the MSDC reference architecture uses Border Gateway Protocol (BGP) and open shortest path first (OSPF) as the control plane protocols.
To support the peak bandwidth requirements of some of these applications, which easily exhaust the bandwidth offered by a 10 Gbps link, the reference architecture uses Cisco Nexus 7000 and Nexus 3000 Series network platforms.
