Video playback test As video is being written to storage, video is simultaneously recalled or reviewed at a rate equal to percent of the write rate. The review did not affect the write rate, video quality, or result in dropped video frames. vSAN cache and capacity disk failure test A single disk failure is the most common failure affecting storage systems today. To assess both resiliency and performance impacts during a disk failure scenarios, both cache and capacity disk failures were induced on the VxRail node. The resulting data resync was monitored with effect to write bandwidth. There was no video data loss during vSAN resync.
