Thanks for the response, Don. To refine my earlier inquiry, the thing I'm having the most trouble with is figuring out the best disk setup. Tell me if my thinking is off on this, but I think I would much rather add processors or RAM as traffic increases than reconfigure my disk array.
I saw a post on one of the other forums outlining a pretty high-volume configuration, but I wonder if someone knows if there is a more economical way to run RAID 1 and how many disks would provide the best price/performance value running OpenACS on Linux. Any specifics would be really helpful and appreciated.
