I am currently running Exchnage 2003 Enterprise on a Windows 2003 STD server edition. THe hardware is a PE 1850 (RAID 1 for the OS). The translogs and data base are on a PV220 storage array. (RAID 1 for the translogs and RAID 5 for the database). I know the Storage array can be put into a cluster mode so both SCSI ports can see the same data. I plan on installing Server Enterprise to upgrade from the MS Server STD. I already have a new PE1950 with the same config as the PE 1850.
My question is if i cluster the OS between the two servers, what is the impact of the the current exchange environment. I am not creating a cluster form two test servers. I have one in production that i want to integrate into the cluster. What is the reporcustions? Would it behoove me to get another PE1950 and cluster them together and create a new exchange cluster from scratch and then move the mailboxes over from my old PE1850? or can i do it with my production environment without any major downtime or outright screwing up my current function infrastructure?
Any and all insight would be greatly appreciated.
Thank you in advance.
