Cloudlab testbed

Cloudlab is a distributed network similar to GENI that comprises around 5000 cores and 300-500 Terabytes of storage. Cloudlab provide 2x10Gbps network interfaces to every node through Software-Defined Networking. The infrastructure contains 100Gbps full-mesh SDN that lets users interconnect a wide range of in-cluster experimental topologies, e.g., fat trees, rings, hypercubes, etc. CloudLab provides two major types of storage: per-server storage (a mix of high-performance flash and high-capacity magnetic disks at a ratio of about 1 disk per every 4 cores), and a centralized storage system. This storage mix enables a range of experiments with file systems, storage technologies, and big data, while providing reliable file systems to researchers who are not interested in storage experiments.

Cloudlab federates itself with GENI. This means that GENI users can access CloudLab with their existing accounts, and CloudLab users have access to all of the hardware resources federated with GENI. CloudLab sites interconnect with each other via IP and Layer-2 links to regional/national research networks, and the core GENI network. A single experiment can include GENI Racks (small clusters distributed across the United States)

Still, Cloudlab offer 3 sites where they have available several type of hardware that are located in the Utah University, Wisconsin University, and Clemson University.
