Hello and thanks for welcoming me to your community. I am working on a new architecture for exchange 2007 and I would like it to be the final architecture for our business. The goal to this architecture is to get X amount of users per box, and more importantly X amount of users per disk. The configuration i am looking at is Raid 10, 4+4 on 15k disk for VIP users (Blackberry) databases, and Raid 1, 1+1 on 15k disk for the logs. I was figuring about 675 blackberry Users on the CCR running on 2 DB arrays, and 2 Logs arrays (1 per server). The second configuration I am looking at is Raid 5, 7+1 on 15k disk for normal users databases and raid 1, 1+1 on 15k disk for the logs. I figured about 1400 users on 2 raid 5 arrays in shared mode (Using 30% of the array) and 1 raid 1 array for the logs. Then, just multiply by the users and it would give out a pre made solution. If you have any reference to something like this being done it would be great also. Thanks for your help. D

Hello Mr D, I would rather use storage calculator to get the count and yes don't forgot to count mail items retention period which is 14 days by default which requires 30% of extra space of your DB, 10% for whitespace & 5% for indexing.

Hi. Thanks for your suggestion. I did use the calculator and have a farely good idea of what the requirements are. My idea is to roll out generic solutions to my clients and avoid having to re architecture everything every time. I am wondering if someone has done this.
