Using NFS over RDMA resulted in impressive outcomes in the content creation scenarios tested. In particular, it enabled workflows that TCP-based NFS is unable to support. For demanding post-production applications running in Linux, use of RDMA with PowerScale OneFS is an obvious choice.
To quickly recap some of the findings:
In terms of speeds and feeds, RDMA is a clear winner for these workloads. But just as important is the reduction in load placed on the workstation CPU. For instance, playing 60 frames per second 4K DCI is demanding. Even when the storage can support it, freeing up the workstation CPU is critical to smooth playback.
RDMA is not for everything. In circumstances with high thread and connection counts, other bottlenecks may be reached. In these scenarios, there is little difference between RDMA and TCP. But for “hero” seats that place the highest demand on storage and workstation, RDMA is by far the best choice.
