Server Specs:

 

Asus P5WD2 Premium

Pentium D 830 (Dual Core)

Corsair DDR2-6400 2GB RAM (4 pices)

2xSATA2 RAID (linux software mirroring)

TE406P (not TE411P as I stated before)

 

Running debian with non-debian kernel (stock standard 2.6.15.4, email if
you want .config )

 

Some anomalies have been observed during the testing of the server
before implementing it into production.

1 - The server performed MUCH better with software RAID one then
hardware, not so mention it was easier to setup.

2 - DDR2-6400 improved some of the benchmarks over DDR2-5200. My
understanding that all samples that come in and out if

Digium card are copied to user space so faster ram should be of benefit
to the system.

 

 

The system has not been restarted from December. Only asterisk was
upgraded 3-4 times since December.

Before unloading zaptel drivers we checked for IRQ misses with zttool
(before each unload/load of drivers) and since December we had none.

 

The system is now running realtime (mysql on the same machine),
iaxmodem+hylafax combo for receiving faxes.

I must say, spending just a little extra to get good hardware pays off
in the long run.

 

If you have any questions, email.
