Hi,

I was planning to upgrade my existing call center setup to one database only, here's my current setup:

Set A:

2 units Asterisk Server with 32 ports Astribank
specs: C2D 2.6Ghz , 2 GB Ram , 250 GB HD @

1 unit MySQL/Php/Apache Server
specs: C2D 2.6Ghz , 2 GB Ram, 250 GB HD

Set B:

2 units Asterisk Server with 32 ports Astribank
specs: C2D 2.6Ghz , 2 GB Ram , 250 GB HD @

1 unit MySQL/Php/Apache Server
specs: C2D 2.6Ghz , 2 GB Ram, 250 GB HD

All has the same specs (All Asterisk) I was planning to centralize all their database into 1 server. What hardware requirements for DATABASE SERVER is needed to centralize the 120+ users at the same time?

They are using Full recordings and maximum of 4.0 dial ratio.

Is Xeon Quadcore 1.6Ghz, 2 GB RaM and 250GB sata raid enough with the said requirements?

My rule of thumb is 25 users/server if you are doing recording. These should still be relatively beefy boxes (dual-core, 2gb ram, SCSI) setups.

I do not encounter problems with asterisk servers. Right now my only concern is what hardware specs needed for the database server with 120+ phones with max 4:1 ratio.

For the database server you should always get as fast of a machine as you can afford. The faster with more RAM the better.

I recently upgraded the database server at a 200 Seat VICIDIAL call center with a server that had the follow specs with great performance results:
- Intel Core 2 Quad 2.66GHz
- 8GB DDR2 RAM
- 4 x 147GB SCSI drives with LSILogic RAID card RAID 10

This is my database server:

Quad Xeon E5310 1.60 Ghz
4MB RAM
Hardware SATA Raid 5

my load on 20 seats is 1.40, and the info of customer, call hangup, is very much delay. and it cause overlapping.. what do you think is the problem?

add --skip-name-resolve --skip-host-cache flags to your mysql startup

add 'skip-name-resolve' below skip-locking in your my.cnf file

Also, check the DNS server that your web server uses as well.

I recently have been using the Asus P5K3, but the P5NT WS does have PCIX if you need that. You could always go SuperMicro as well. Something like the C2SBX is about the same cost as the Asus boards.
