Sizing Exchange 2007 for Unity

Greetings -

I have a customer that currently deploys Exchange 2003 housing approx. 350 email mailboxes. He looking to integrate a Cisco IPT solution (CUCM 6.1 and Unity 5.0). Before the IPT integration he wants me to install a new Exchange 2007 server. I would like to "size" the new Exchange 2007 server to take into consideration the Unity 5.0 install.

Does Cisco provide any "sizing" tools/documentation/recommendations for an Exchange 2007 server when integrating w/ Unity?

Any information would be greatly appreciated.

Thx

Joe

Re: Sizing Exchange 2007 for Unity

It's not really sizing on the Exchange 2007 box that matters. What matters is how much space you are allocating to Voicemails. For instance, I think the ratio is 30 minutes of voicemails is about 15megs of space required. (at G711 codec)

So do the math:

350 mailboxes

30 minutes of voicemail recordings

15 megs per 30 minutes

350*15 megs = about 5gigs of extra space required.

People can of course more voicemails to "personal folders" and store them like any other email attatchment, etc.

hope this helps

Thx.

The information you provided is very helpful. I was more-or-less looking for a rough calculation of VM storage.
