Hello Again Just my two cents,
I am not a fan of SBS do to the fact that it puts too much on one box. I think that a server that you use as an AC server and Exchange is a bad plan. I think that exchange should be on its own box and the same goes for other major server rolls.

As for raid you MUST go raid and you must be at least mirrored the speed of a rebuild is not as important as having the redundancy, if one of your ?correction? when one of you drive fails you will have your raid to fall back on. It will keep you running until you can rebuild. If you go Dell they use PERC to control raid and it very straight forward to configure.


For the client that we have using AC we have installed a total of 4 Dell 2950 servers.
First Server:
Untangle box. This is a Lenox based system it's a great solution for NAT,Firewall,VPN,virus protection and web-filtering network wide. OS is Lennox

Second Server:
Domain Controller for Active Directory, Exchange Server 2007, GFI Fax Maker. OS is MS Server 2003 Standard

Third Server:
DATA Server. This SQL server that is hosting AC and we have written a custom reporting front end that links data from AC to a supplemental database to facilitate the generation of California state work comp forms ?Doctors First Reports, PR-2 and End Of Care forms.? As well as a much better method of Clinic reports and documents than AC is capable of. OS is MS Server 2003

Forth Server:
Application server . This server is how all the workstations in the clinic run AC, Office, Dragon Med and a number of other misc apps. This is done by sharing the applications and at the workstation level it functions as if they are just running a program locally ?just an icon on the desktop? not having to run a full remote desktop connection. No data is generated at the workstation this eases in backups and one location to upgrade that will affect the whole clinic. OS is MS Server 2008 r2 with 32 Gigs based on the amount of users.

There are 17 workstations running in this clinic as well as iPads and some tablet PCs all of them run AC. Because of the Application Server it allows cross platform to other devices and users can go to any workstation and keep their workspace just the way they left it even remotely.
This clinic has 4 provides and sees about 150 patients per day

A little bit about me,
I am not a Doc, at least not a human Doc but I am a network engineer since 1989. I have been consulting to ambulatory clinics as my own company now for 6 years since crossing over from designing and managing POS and accounting systems in retail corporations. I enjoy helping out where ever I can.
