RDMA Containers Update

In this video from the 2016 OpenFabrics Workshop, Haggai Eran from Mellanox and Parav Pandid from HPE present: RDMA Containers Update.

"Container technology provide improved isolation capabilities and fine grained resource control for Linux applications and services, and has recently risen as a light weight alternative to machine virtualization. Although there has been progress in supporting RDMA applications inside containers, much work is still needed. Basic support for using RDMA CM inside a network namespace has been accepted upstream, as well as an implementation for InfiniBand. However, RoCE and iWARP support for network namespaces is still lacking, and there is not yet a mechanism for controlling RDMA resource usage inside a container.

In this talk we wish to expand on the missing pieces, and present our work on RoCE network namespace support. In addition, recent work on an RDMA cgroup provides a way to set hard limits on the number of RDMA resources a container may use, allowing the administrator to allocate per-device QPs, SRQs or CQs to different containers. With these technologies in place, users will be able to enjoy the performance characteristics of RDMA with the flexibility and efficiency of containers."
