asterisk users - Jul 2005 - MeetMe hardware dimensioning

Hi all.

What is the best hardware configuration to handle this following  
scenario?

- 4 IVR menu with conference applications for each option;
- Only SIP/g711 user access
- 3500 simultaneous users(800 at the beginning)
- No ZAP channels

Where is the most important point of failure? CPU? Ethernet? RAM?

Im planning to separate in three servers:

Server01: 01 Xeon 3Ghz getting the 1st level of the 4 IVR options.
Server02: 01 Xeon 3Ghz with 2 IVR suboptions and 2 conference room
Server03: 01 Xeon 3Ghz with 2 IVR suboptions and 2 conference room

How it sounds to you?

Denis.

If your 3500 users are consumers representing perhaps 175 simultaneous calls
you should be fine with three servers. Depending on conferencing load and
transcoding, two may be enough. You should have n+1 servers for redundency,
all with RAID. Then you don't need to worry about subsystem failures. 

If your users are business people they ratio to 1100 simultaneous business
calls and you will need  6-9 Lintel servers, again depending on the
conferencing load and the transcoding.

I think that I will be in this case. That is a PalTalk like project.

What is your opnion about the separation of the services? Would you  
use the 6-9 lintel to handle each one a separate service, or your  
plan is to have some redundancy?

What is the hardware configuration that you recomend for each server?  
Xeon 3Ghz each?

Thanks.

Denis.
