I'll always spec more disk if I'm starting to get over 75-85% on a consistent basis, but over the past 3 or 4 years, the number of arms and speed of the disks has been more relevant here and I've been nowhere near the threshold. So, my production machine is suffering at about 33% used right now. Yet I still go after the app guys for cleanup as another concern is keeping the backup window under control. FWIW, the production machine is a 730 with 65 17.5GB drives, 2 ASPs, and RAID5. -----Original Message----- From: Condon, Mike [mailto:M1C@xxxxxxxxxxxxxxxxx] Sent: Wednesday, November 19, 2003 9:55 AM To: 'midrange-l@xxxxxxxxxxxx' Subject: %ASP Used I'm going to survey you all on what %ASP Used you try to keep your production systems at, and when you begin to panic or implement a cleanup. Thanks in advance.
