asterisk users - Aug 2004 - Harddisk noise on TE410P

Hi,

I have this strange problem I need some help with.. It appears that I have
harddisk noise captured by a Digium TE410P card (Same problem on 2 identical
machines..) The machines are two Compaq Proliant DL320 G3's...

Does anyone else have this problem..

Kind Regards

Claus Futtrup

You can actually hear the hard drive noise when calling out or receiving 
a call? A clicking sound, or like an electrical noise?

I doubt this is being done through the motherboard, how close is the 
card to the power supply and/or the power wires going into the hard 
drives? Are they less (or more) shielded than normal? Have you tried it 
in a non-Compaq proliant server?

Claus-

This is a problem that interests me, as I'm about to deploy TEN of these at
a customer site, all with TE410P's.

I'm currently load testing one Proliant box (3GHz P4 processor) looping 59
calls out to 59 calls in (leaving one channel open) - ie: lots of load.
While I'm doing this, I call in from another asterisk box over IAX, route
this call out over a TE410 channel and back in, and listen to a prompt.  I
don't hear any unusual noise, and the box is performing well otherwise.

Please supply more detail: What kind of disk, which Linux distro - and, what
is the noise you're hearing?

Thanks
