DENT – A Linux Foundation Project

A new collaborative open source project was launched by The Linux Foundation with the aim to create a full featured network operating system that simplifies enterprise edge networking software.

 

 

The open source project DENT was launched in December 2019 under the umbrella of the Linux Foundation with the aim to simplify enterprise edge networking software. The founding members – Amazon, Cumulus, Delta, Mellanox, Marvell, Wistron NeWeb (WNC) – call out for a collective participation of system integrators, original design/equipment manufacturers and end users of the industry to contribute to a full-featured network operating system for distributed enterprise, campus and remote/branch offices. The Linux Kernel, Switchdev, and other Linux-based projects function as the groundwork for the collaborative creation of the new standardized network OS for disaggregated network switches.

 

By launching this project, The Linux Foundation enables the establishment of a technical open source community engaged with the creation of a network operating system by contributing control plane and management plane use cases which are applicable across various industry solutions. The collaboration of developers, service and solution providers and end users is crucial to leverage disaggregation within the networking stack and standardized integration across the ecosystem of data centers and telecommunication. DENT benefits from the Linux Foundation’s ecosystem of solution providers and users.

 

About The Linux Foundation

Founded in 2000, The Linux Foundation now fosters a community of more than 1,000 members across the open source industry and leverages collaborative projects on open source software, open standards, open data, and open hardware. The foundation provides financial and intellectual resources, infrastructure and services to support contributors, users and solution providers in the creation of shared technology. They organize frequent events and trainings and invest in promising projects with a focus on the development of open source ecosystems.

Partner Case Study: Edgecore and Cumulus on Campus Network

, ,

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

Background
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.

 

Solution
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.

 

Edgecore AS6712-32X

  • Spine switch supporting 10G or 40G spine interconnects
  • 32 fixed x 40 GbE QSFP+ switch ports in compact 1RU form factor
  • Full line-rate Layer 2 or Layer 3 forwarding of 2.56 Tbps full duplex

Edgecore AS5712-54X

  • 10G Top-of-Rack Switch for enterprise and cloud data centers
  • VXLAN and NVGRE tunneling support in hardware for network virtualization
  • Full line-rate Layer 2 or Layer 3 forwarding of 1.44 Tbps full duplex
