our server is E5-2650 with 128 Giga Ram and ssd Hard disks.one of our customers wants to stream to 5000 viewers with the following options 5000 viewers @ 1024kbps 5000 viewers @ 1792kbps 5000 viewers @ 2048kbps 5000 viewers @ 3072kbps what port should we use? would it be enough 10Gbps port on …

Hello @Paul Santos It would be hard to tell without load testing first, since there’s several factors of how many incoming streams, transcoding, using SSL, etc. Here’s how to request the load test tool: https://www.wowza.com/docs/test-wowza-streaming-engine-media-server-streaming-load How to siz…

Hi @Paul Santos, Is that 5000 viewers per bitrate, or 5000 viewers total? A rule of thumb for the required bandwidth when using HLS is: [number of concurrent viewers] x [average bitrate per viewers] x 1.2 That would be 5000 x 1024 x 1.2 = ~6.1 Gbps for the lowest bitrate, or ~18.4Gbps for the hig…

That depends on the CDN, @Paul Santos. Drop me an email; karel.boek@raskenlund.com, and I’ll get you some more info.

Karel going back to my question,is there a limit for RAM, that it is useless to have more than a certain amount because it will not change anything? I mean a server with 128 Giga of RAM and 256 Giga of Ram; will the 256 Giga be better or all considered the 128 Giga is enough? Thanks

As for RAM, I’d say 128G is overkill. Typically I recommend 16-32GB, because default Java Heap size is 10G and you almost never need more than that. In your case, you may want to expand the Heap size, if you see from your load tests that the Java Heap is filling up. But I wouldn’t make it too large,…

Thank you Karel, I think I understand. This customer is streaming live for the last 5 years from my servers, so I think he is quite satisfied. But how much it would cost 5000 @1024 with CDN ?

Thanks

Paul
