I have a new SuperMicro system, and I need a little help troubleshooting some choppy playback, or wondering if this is even possible
The system is a 7048GR-TR with 2 18 core processors. This is hooked to a Cubix expander and I have 3 1080Ti GTX cards(will soon be 4), 1 in the PC and 2 in the Cubix. The hard drives (8 x 8TB) are connected via a 6Gb SAS connection and are in a raid 5, a BlackMagic Disk speed test yields around 1000 MB/s in read and write.
The plan is to be able to play a timeline back with 6k raw media on a UHD timeline. If I could play 1 track of video I would be happy, no expectations of multiple raw tracks.
Currently the playback is choppy. I set up a performance monitor for the GPU's and they only go up to 20% usage, cpu shows 80%, disk shows only 20% usage at 200MB/s max.
Is this most likely a response issue of the hard drives, or what is likely the playback bottleneck?
Thanks,
C
