I'm about to pull the trigger on a new database server. I'm getting the oppurtunity to build from the ground up here. Main problem is "the powers" have absolutly NO CLUE what db performance will be, so I get to guess. This makes one of my main requirements flexibility. My other requirements are redundancy and failover with performance following in third place. Size will be under a TB for quite a while.
Current thinking is 9i RAC on RHE 2.1 with a NetApps filer and IBM xSeries hardware. NetApps box would be dual attached, on a dedicated GB LAN segment. I'll take any general comments on this configuration if anybody out there is using something similar. I'm assuming I can add processors, servers, spindles, etc. if I find the DB performance is poor and the developers won't fix it. There will be multiple Oracle instances.
My other requirement is redundancy in the form of hot site failover. I have two options, NetApps SnapMirror or Oracle's Data Guard. I have no direct experience with either so I'm looking for pros/cons to both. The requirement up front is how kind the mirroring/replication is to the bandwidth between the sites, followed by features and flexibility.
