In this video, William Wallace from insideHPC interviews VMware‚??s Josh Simons (http://communities.vmware.com/community/vmtn/cto/high-performance) on the topics of virtualization and RDMA, high performance computing, and Big Data. Recorded at the Open Fabrics Workshop (https://www.openfabrics.org/ofa-workshop.html) on March 26, 2012 in Monterey, CA.

Josh has also posted some interesting notes (http://communities.vmware.com/community/vmtn/cto/high-performance/blog/2012/03/26/rdma-on-vsphere-status-and-future-directions) on his presentation on RDMA at the Workshop:

In my introduction, I showed a few graphs from our upcoming paper, RDMA Performance in Virtual Machines using QDR InfiniBand on VMware vSphere 5 that showed we can use passthrough mode (VM DirectPath I/O) to deliver 1.75us half ping-pong latencies for Send and 3us for RDMA Read using polling completions and 7.6us using interrpt completions for RDMA Read.
