Currently we have a back-end email infrastructure of

- Exchange 2003 hosting 30,000 users
- on a Microsoft cluster of 2 Active nodes and 1 Passive node
- running on Windows 2003 Enterprise Server and Exchange 2003 Enterprise

We wish to implement a BES environmet of

4 BES servers each hosting 500 users
1 SQL server only to service the above BES servers

I would appreciate some advice and recommendations for

1) 4 BES Servers - hosted on Windows 2003 Standard or Enterprise?

2) SQL Setup - hosted on Windows 2003 Standard or Enterprise?

3) SQL Setup - SQL 2005 Standard or Enterprise?

advice greatly appreciated

thank you

Tony
