asterisk users - Mar 2008 - capacity

Hi,

 

I am planning to deploy an Asterisk system to supply 4-6,000 students with
voicemail capabilities. The system will be set up with non-DIDs, route
incoming calls to voicemail, then send an email notification.  Anyone with
some ideas on how I should go about spec'ing the server this use?

Strictly VM?  How are the calls going to arrive?  How many
simultaneous accesses, both leaving messages and retrieving (highest
peak).

I believe Vonage uses Asterisk for their VM (not sure where I heard that).

And I can post a link that shows a bunch of guys think the earth is
flat with a 5/10 google ranking also (like the barf guys).

I usually just call my guy at CDW and give him my needs, he is a
former techie gone sales.  He puts together a quote and emails it to
me for approval.

I find HP server are very robust and rock solid at a decent price
point (IBM as well).  I like the 380 because you get six hot swap scsi
bays and redundant power supplies in a 2u profile, also, Digium and
Sangoma T1 cards have never given me an issue.

Many on this list love Supermicro, I have yet to try them but I will
in the near future.  I have not heard a single complaint, only rave
reviews.

I guess my original point was going for redundancy as far as storage
and power supplies with your dollar, not the fastest proc or maxed out
RAM that will not be needed.  Regardless of the actual hardware or
RAID setup, that is the angle I suggest you take.  4k - 6k students
will require quite a bit of storage.

Thanks,
Steve Totaro

Steve,

My purpose was to try to point out that Raid 5 has deficiencies, and I would 
not recommend a Raid 5 set. 

With the disk sizes available today (both SATA and SAS), Raid 10 or multiple 
Raid 1 sets have many advantages.
