Hardware requirements

[oscar huvh]

Hello
We have been testing openmeetings with an excellent result. So we'd like to implement it in a production enviroment.
I guess that once openmeeting is populated some departments will want to join it so I wonder what hardware requirements will fit in our case.
I think we probably will have several conferences at a time and it will be common having 8-10 participants in the most succesfull conference.
Sharing desktop and documents will be the most used features.
We don't integrate openmeetings with moodle or other programs.
I was thinking in installing a CentOS 64 bit in a HP server Proliant DL 380 G7 with at least 8 GB RAM.
I assume that openmeetings doesn't need much HDD space and the most important devices to upgrade in the server are RAM and NIC.
Does anybody has an enviroment like that? I'd like knowing about servers has been used and their results.
Thanks in advance
Regards

You should be able to roughly server between 500-1000 concurrent users on such a server.

But of course it is connected to what usage scenario you are doing:

If you have only 4x4 Conference rooms (4 participants every participant with Audio-Video turned on)
4 Audio/Video Users = 4 (4-1) stream = 12 streams
1 stream = 70 KByte / Sec
12 streams = 70 * 12 = 820 KByte / sec for a single conference room
820 KByte / sec are the download AND upload rate

You might run out of bandwidth very soon on your server.

If you have webinars with 2 presenters but 100 listeners in the restricted roomtype you might have more concurrent users.
2 presenters = 2 * 70KByte/sec = 140 KByte / sec Upstream
100 listeners = 100 * 70 KByte / sec = 7000 KByte / sec Downstream from the server

The CPU is also an important number in terms of max usage.
