Should I cluster my exchange server?

I currently have a Windows 2003 network, running an Exchange 2003 Enterprise Server.  I have the following:
- 140 users, growing to about 160 in next year
- priv.edb = 150GB
- priv.stm = 37GB
- user mailboxes  over 2GB = 40

- I am looking into a mail archiving program at the moment, if we can afford it.

I wanted to cluster the exchange server for redundancy.  Is this a good idea and what are good arguments on this, so I can explain it better to the check writers? Should I get 2 new servers and start from scratch and move all mailboxes to the new server and remove the old one?

Also, is it a good idea to put another exchange server in the network and have a front end & back end server?

I really struggle to justify clustering for any site. Most sites that think they need clustering actually don't. With good quality hardware and if the server is well built the "benefits" of clustering do not outweigh the considerable costs.

You would be looking at a new installation of Windows and Exchange, you cannot cluster an existing server.

As you would have to buy Exchange 2007 licenses and then use downgrade rights, what I would be looking at doing is buying new hardware and licenses for Exchange 2007 and then using the new features that Exchange 2007 offers for increased redundancy.

Another option would be to look at something like DoubleTake which can mirror the server to other hardware.

I agree with Sembee. My view of clustering and the like is that you add another layer of complexity, thus increasing the risk of anything going wrong. As Sembee says: Use Good Quality Hardware. Also Be An Expert On Your Own System.

i would also think about implement quotas, quickly. i would also create a new sg and mbx, and move half your users over there. reason being 150 gb is getting kind of large, and i would be worried about backup/restore with that size.

if you do a 2007 server, you can have a separate cas if you like, or do all in one on one or even two boxes. then just expose one to internet for owa (if desired).

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Thanks for all the great suggestions, I will split up point among all.  I realize now that this should have been placed in a different section.

Kristinaw:  I tried creating a 2nd sg.  But I had a problem, I have users that need to add additional mailbox accounts in Outlook for access.  If the user's account is in SG#1, and a second mailbox, say its named "Accounting",  I could not open the mailbox.  Even if all the correct rights are there.

If the mailbox was already in Outlook when you moved it, you will need to drop it from Outlook and restart Outlook. Then add it back in again.

moving to new SG actually worked this time, and I know I did the same thing now as before.  No matter, it works.  Thanks all for advice.
