Hi, Our Customer wants us to install one Server who can handle 1 Incoming Llive Stream and handle on the same Hardware over an iis 1000 simultane Clients. The incoming stream is 1080P and also the outgoing Stream should me 1080p.
We need to know if our HW is sufficent enough to handle all that together.
The Hardware wo thought:
8Core 16HT CPU
64GB Ram
4x SSD in a RAID 10
Nvidia P6000 for transcoding
1x 10Gbit NW for the clients
1x 1Gbit NW for the incoming Stream
We know that the NW Cards can handle the Traffic our Question focus is on the CPU handle the 1000Client requests

Maybe this is usefull for you.
https://www.wowza.com/docs/how-to-get-flash-rtmp-load-test-tool although its only for rtmp streams. Maybe the support team can tell you moren on this tool
For more detailed info i think its best to open a support ficket for your needs.
@aaaaaaaaaaaaaaaa hhhhhhhhhhhhhhhhhh
I think Hardware Server Spec, this can be done according to your needs.
from my experience.
I suggest that you should control Incoming Stream Source 1080p bitrate not to exceed 4Mbps.
and Transcoder Output should not exceed 4 Profiles.

That’s enough hardware. Can you let’s me know server brand or model?
