I have a HP DL360 G4 server (2x CPU @ 3Ghz, 2GB ram, 2x72gb hdd) in RAID 0+1.
Our domain setup is 6x servers (PDC, Terminal, WSUS/Websense, File/Print, Exchange, SQL. There is a Microsoft OVS agreement for Windows, SQL, Exchange in play as well as Office.
I'd like to use the new server to act as an emergency substitute for the PDC, Terminal, File/Print, Exchange and SQL; whilst this configuration may not be supported by Microsoft for example, in the event of a disaster it will do as a work around till we get everything working properly.
I can add the services as needed e.g. DNS, DHCP and setup the server on an alternative IP range in the same subnet and make any changes necessary.
The idea being that the server is on the domain for say 24/48 hours to replicate the information then it will live offsite, being hooked up on site at regular intervals to replicate (or the replication is done down the line via VPN (ideally out of hours e.g. Sat/Sun.)
I don't need file by file replication just the listed services as the files can be restored from the backup tapes.
The server comes with a license for 2003 server std and 5 cal's and i would like to keep the above in line with this limitation so we don't incur any additional cost.
The server, SQL and exchange will ideally be setup and configured then kept offline (cold server) which i believe is permitted in the OVS again to keep the cost down however the reason for this question is to clarify so please correct me if i am wrong.
In the event of a disaster, the server would be re-comissioned wherever necessary and the MX records for e-mail re-directed and staff will acess via RRAS (how do i set this up securely) and log in to the Terminal Server aspect, use OWA etc.
Hope this makes sense, i've put the points as high as i can as i realise i'm asking a lot of information....
