I was about to order a Dell R720 to transcode around 60 1.5Mbps streams coming in, to be transrated realtime to 4 other bitrates.
However, I just noticed this Note on the NVENC encoding page:
Note: Currently, NVENC-based video encoding is limited to approximately 30 simultaneous encoding sessions. NVIDIA is working to address this limitation in a future driver update.
Any insight into the details behind this and any timeline for them to update? Not sure when this was noticed or when it was posted. I did see that 3.6.3 is updated to NVENC SDK 3.0, so maybe this is resolved?
