We are getting ready to migrate approx. 300 users from SendMail on a RedHat box over to Scalix running on RedHat Enterprise 4. I anticipate that we will have 50 premium users and the remaining 250 will be Standard or POP users. My questions are:
1. Do I need multiple servers or will a single high-powered server be sufficient?
2. Is there a load-balancing scheme that Scalix uses if I wanted to use more than one box? (Or, do I just put half of the users on 1 box and the other half on the second box?)
3. Is there a rule of thumb for the number of users that should be on a single box or in a single message store?
Thanks for your help...
