Actually, those disks are only marginally larger in the one statistic that counts. The number of I/O's per second is the driving performance statistic for production databases. I usually point out to them that if all you had was a 4 cylinder engine for your vehicle then buying dump trucks just because they are larger would not yield a desirable result for the typical family of 4. You have to find analogies that are within the experience of bean counters in order to explanin things to them. The one above has worked for me a couple of times. Be careful though, demeanor counts.

Hi,

I was wondering how DBAs are coping with these new large disks that are available....you can purchase 36gb, 72gb, etc. You can fit a whole database on one of these. But with all the performance and redundancy considerations, you wouldn't....so what do you do with the free space? Or how do you tell your bean counter that out of that 72gb you are only going to use 10gb so you need a couple of these?

Rgds, Ken Heng
