Exchange 2003 Network Design Question
Posted on 2006-07-19
We are currently planning a Groupwise to Exchange conversion (I know---why go to Exchange, but we were told we had to). My task is to come up
with the most secure, yet functional implementation of the server layout / design. We have a heavy use of OWA and about 1000+ accounts. What
would be the best way to setup the design? We are to use an appliance for the SPAM / AntiVirus as well. I am stuck between Barracuda and Symantec's 8200 series. I currently have though of 4 different layouts...
We have a Firewall - DMZ - Internal Network
1. FW | Appliance + Front End Servers | FW | Back End Servers and AD
I put this in just so I could shoot it down. I am not planning on this but maybe the experts think it is the best.
2. FW | Appliance + Apache on sun/linux | FW | Front End Servers, Back End Servers, and AD
I am leaning towards this approach
3. FW | Appliance + ISA Server | FW | FES, BES and AD
MS recommends the ISA server obviously but it seems overkill in my situation
4. FW | CipherTrust Appliance + CipherTrust proxy | FW | FES, BES, AD
Cipher Trust supposedly has 2 appliances that can do the proxying and AntiVirus / AntiSpam (We are still researching)
Does anyone have any suggestions on what layout to use and what appliance to go with? There really is not a budget. I was told to make it work
in the most effective yet secure way :)
