diskuse on SAN

[Morten Kristiansen]

Hi,

On direct attached disks or local disks the rule is not to have over 90% used disk capasity. But is that true on a SAN disk as well?

From what I've heard it is the filesystem that works harder and slower when the disks has a diskuse over 90%. Is that true no matter what type of disk and disksystem you have, and what files you have on those disks (ie. database files which does not extend any more, ever)?

We are running on hpux 11i and are using vxfs as filesystem.
