[asterisk-users] Re: Dell PowerEdge 2950 Sharing NIC IRQ with Digium Card

[Matt]

Er... no you don't :)    My problem and everyone elses with Dell is that
Dell builds the Mobos to share the PCI IRQs with the NIC cards.   I've got
some SuperMicro MoBos running VoIP and they DO share exactly like you
showed.

There is nothing wrong with sharing your VGA (Video) with your PSTN card.
99.9999% of the time that video is just going to sit there doing nothing.
And when it is in use, it isn't much.. unlike a network card that, well,
with a VoIP server, kinda gets hit hard.

I wouldn't worry about your IRQ sharing... that is exactly the kind of
sharing that is ok.  However, sharing real-time NIC with real-time PSTN
interface == BAD.
