Thought you might be interested in this one....
A customer sent us a machine to install last week. Monday morning a Dell 1950 dual Quad-Core Xeon turns up. It's an absolute monster with a state of the art RAID controller, a pair of hot-swappable SATA drives and a couple of Gigs of memory all in a 1U "pizza box". He's going to run an E1 circuit off it so in went a top-of-the-range Digium TE212P 60 channel card with on-board DSP echo cancellation.
No PS2 ports on the machine (USB only) so we stuck a USB keyboard on it and plugged up a screen. Popped the SME7.2 .iso in the CD bay and crossed our fingers. We needn't have worried, SME installed on it without a hitch. Get this... a full SME Server install from closing the CD drive tray to the reboot took just over 4 minutes! Good grief, this thing is rapid. A boot up from cold to the linux login takes under a minute.
Asterisk Business Edition went on without trouble and SAIL2.2 followed soon after. The only criticism we have is that udev is very slow (something to do with the number of CPUs maybe?) and seems a bit fragile. We've managed to lock the box up a couple of times by rapidly stopping and restarting asterisk (which unloads and reloads the drivers). As long as you pause for a few seconds between restarts, it seems to be OK.
According to the latest benchmarks we've just got from Digium, this box should be able to run about 1600 simultaneous voice calls.
Wow!
