Feature Overview

The Openshift Sandboxed Containers product was initially bootstrapped to serve a requirement from one of our biggest telco-customers. That said, performance is an important requirement for Telc-workloads. We are already covering the deployment side of things with https://issues.redhat.com/browse/KATA-430. However, there are many other parameters that would contribute to achieving better performance especially in the context of NFV.

In this feature, we are covering support (enable, test, and validate) for SR-IOV and DPDK in Katacontainers, with SR-IOV improving the performance for North-bound traffic and DPDK for East-west traffic.

Background, and strategic fit

By supporting SR-IOV and DPDK we are covering one of the basic requirements for telco-use cases and enabling other Telco customers to onboard and adopt Sandboxed Containers (Kata).

 Goals

• Cover testing and validating all the functional bits and pieces required to get SR-IOV and DPDK to work with Kata (VFIO, netdevice addition, IOMMU, Hugepages...)
• Cover performance-measurements related tasks.
