The first test was playing back an uncompressed DPX image sequence at 8K DCI resolution, 1x image sequence per client. These frames were each approximately 190 MB. Each client would need 4,560 MB/s of performance to sustain 24 frames per second playback.
The 3-node F600 cluster could sustain playback of 2x simultaneous 8K image sequences total using RDMA. Adding the third client caused dropped frames. Rerunning the test with the F600 mounted using TCP, the 8K image sequences would not play at all, showing that RDMA was vital in this workflow.
