I was hoping that you would be able to offer abit of advice on a new Dell
rack mount server for Exchange 2007.

Users: 65
Max Mailbox Size: 500mb Initially although once old GroupWise archiving is
completed this will reduce to 200mb/250mb
Usage: Medium to Heavy usage

We are moving across from a Netware/GroupWise environment and it is logical
to move to Server 2008/Exchange 2007. Despite the relativley small user base
I think its best to have fileserver, dns, dhcp, domain controller, global
catalog on another server leaving Exchange on its own box.

And why Dell? We have a Dell premium account and in my years as an admin I
have never experienced any major issues. Swings and roundabouts choosing
between Dell and HP from what I have read. PowerEdge 2950 seems a logical
choice but I am no expert.

This is only to provide an initial idea and I intend on having a day of
consultancy prior to purchasing everything to run over migration plan.

My greatest concern is over doing it of the spec side of things. I've come
from an environment of 400 odd users so 65 is not a huge amount.

In terms of disk arrangement i'm thinking:

System RAID 1
Logs RAID 1
Mailboxes RAID 1/RAID 5/RAID 0+1?

Is the above over doing uit for just 65 users?

Would anyone have any recommendations for such a server config? 8 gig of RAM
suffice?

Mailbox, Hub Transport, Client Access will be on the one server. No need for
edge as firewall is locked down to only receive from our Mail Filtering
provider. All archiving done on external mail filtering and Exchange 2007
journaling will provide archiving of internal mail upto email filtering
provider. Exchange Standard version should suffice.

Thanks for any feedback - if your interested in anything else please let me
know.

ps for those migrating from GroupWise the Quest tools are a must! Working
very well in test environment.
