Subject: Disk: Percent full a performance factor?
The old rule of thumb I had learned back on the S/36 was that you really didn't want to go over 80% of disk space used. I had a manager (came from the programmer pit and rose through the ranks) that wondered if that still held true with the growth of disk. After all, 20% free of a whole gig of disk space sure was a lot more than 20% of 300MB. I argued that object size was significantly larger and that reorgs and whatnot still needed significant portions of disk space.
Now that we're measuring disk in TB and MB is nought but a rounding error does 80% still hold true? If so, why?
