The University of Texas at San Antonio (UTSA) operates massive workloads for large enterprises while educating its own students on cutting-edge open source technologies and providing research opportunities, all within the constraints of a tight budget.

The recently published case study shows their Cloud and Big Data Lab ecosystem leveraging Edgecore Networks 10G/40G Open Networking switches and Cumulus Linux to simplify their stack and enhance flexibility, while reducing acquisition cost and operational expenses.

Product Deployment

  • 2 x AS6712-32X 40G data center switch, serving as spine switches with 40G downlinks to leaf switches
  • 4 x AS5712-54X 10G data center switch, serving as leaf switches with uplinks to spine switches and downlinks to controllers and compute nodes
  • Cumulus Linux operating system

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.

As a rapidly evolving environment, the data center of UTSA must grow at a rapid pace while enabling research projects based on the latest technologies, within the constraints of a tight budget.


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


As the first OCP-approved 10G/40G switches, Edgecore open networking switches with 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.


The disaggregation goes one step further with Cumulus Linux: As a native linux network OS, it supports both networking and a range of widely available server packages, mostly open source. Switching from the world of various network operating systems, the team rapidly felt comfortable with Linux, a familiar tool. With Cumulus Linux, the switch is just another server with many accelerated ports; the administrator only needs to understand Linux. Since UTSA computer science graduates are skilled in UNIX/Linux, adoption was easy once they complete the program.

By leveraging Edgecore Open Networking technologies with Cumulus Linux, UTSA achieved simplified their stack and got flexibility that resulted in reducing both CapEx and OpEx.

For all who are not familiar with PICOS® or the Edgecore AS7816-64X, I added some information down below. Some content is taken from the official websites of Pica8 and Edgecore and I do not claim ownership of it*.

PICOS® Enterprise Edition from Pica8

The PICOS® enterprise edition offers the most comprehensive support for enterprise features on the market and includes the Debian Linux distribution – with an unmodified kernel for maximum DevOps programmability – L2/L3 switching and routing; and full support for Pica8´s revolutionary CrossFlow™ capability. Only PICOS® Enterprise Edition can control every switch port in a network using both L2/L3 protocols and OpenFlow at the same time. CrossFlow, which is only available from Pica8, tightly couples the L2/L3 and classic SDN control planes to give network operators real-time, non-disruptive control of their enterprise applications, deep and dynamic traffic monitoring, and even attack mitigation without interrupting flow processing or requiring switch restarts. Over 1,000 customers in 40+ countries – and counting – have already deployed Pica8´s open standards-based Network Operating System to solve some of the world´s toughest next-generation networking problems.

Edgecore AS7816-64X

The Edgecore AS7816-64X is a Top-of-Rack (TOR) or spine switch for high-performance data centers. The switch provides line-rate L2 and L3 switching across 64 x QSFP28 ports, each supporting 1 x 100GbE or 1x 40 GbE, or via breakout cables 4 x 25GbE or 4 x 10GbE. The AS7816-64X can be deployed as a TOR switch supporting 10/25 GbE to servers with 40/100 GbE uplinks, or as a spine switch supporting 40/100GbE spine interconnects.
