Re: How would you layout the files?

The no RAID option is definitely old-school and I realize I am dealing with some old-school thinking. I guess I've been spoiled over the last many years with storage abundance that this one throws me back to the old days (even then, I had Sun boxes with abundant enclosures). I know redo logs are nice and sequential, undo is a huge read/write monster, and everything else is somewhere in between. It's balancing the sequential reads versus the scattered reads. Hopefully, this client will see the light and the red tape will be cut to get a better system with appropriate storage. My current production environment is clustered HA storage, multipath fiber, RAC, blah, blah, blah (paid a lot for the multi-blahs by the way). So having been with that for a while, it's odd seeing this single box approach with a database that nearly approaches the disk size of each individual disk. Perhaps, they can get the 300GB option if only to delay space issues. Sigh.
