Case Study - UTSA use Cumulus and Edgecore switches

Case Study 
The University of Texas at San Antonia leverages Cumulus Linux and Edgecore Networks 10G/40G open networking switches for choice and simplicity, extending its Cloud and Big Data Lab for research and education.
The University of Texas at San Antonio (UTSA) is a state research university in San Antonio, Texas, US. With over 30,000 students, it is the largest university in San Antonio. UTSA is also home to the first Open Compute Project (OCP) Certification and Solution Laboratory in North America. The laboratory serves the goal to certify Open Compute technologies and key workloads for large enterprises while educating its own students on cutting-edge open source technologies and providing research opportunities.
Having seen at the first hand the benefits of open technologies and ecosystems, it was only natural for UTSA to adopt Cumulus Linux, the Linux network OS that enables a rich open ecosystem and that works on top of the Open Network Install Environment (ONIE), the essential building block for open networking.

Leaf and Spine Topology for Data Center

UTSA leverages OCP networking technologies with Cumulus Linux in the UTSA Cloud and Big Data Laboratory and in various cloud projects for research and education. Over 90% of server ports are based on OCP technology. Now, two thirds of the network infrastructure is based on OCP networking with AS6712-32X 32-port 40G switches and AS5712-54X 48-port 10G & 6-port 40G switches from Edgecore Networks.
Why Edgecore Networks
The Open Network Install Environment (ONIE) enables choice. Users have the option to run the operation system they want on the hardware device they want to purchase. As the first OCP-approved 10G/40G switches, Edgecore bare-metal switches with their pre-loaded ONIE enable different network operating systems to easily run on top of the Edgecore hardware, disaggregating the models with ONIE and Cumulus Linux. This disaggregation gives power back to users, with Linux as the network OS and the server OS.
Models used in the case
2 units AS6712-32X 40GbE data center switch with 32 QSFP GE RJ-45 ports, 4x10G SFP+ ports, and 2 QSFP ports, serving as spine switches with 40G downlinks to leaf switches.
4 units AS5712-54X 10GbE data center switch with 48 10G SFP+ ports, and 6 x 40G QSFP+ uplink ports, serving as leaf switches with uplinks to spine switches and downlinks to controllers and computer nodes.
