I'm responsible for 3 (soon to be 6) Tahoes, CCI's own Power 6/32
running CCI's SysVR2.22 and OFFICE POWER software. Presently they
have 8 megs & 1 processor. Plans are to increase memory to 16M. All
systems have 1 controller & two drives. One test machine (lucky one!)
will have an additional drive & controller.
I'm interested in some guidelines on what numbers I should be looking
at when using the sar utility. Inode tables look good. Hit ratio on
reads is 95%+, but on writes it hovers below 80%. sar -u often shows
%wio over 20%. I suspect that increasing the size of my disk caches
will improve performance (although performance is already more than
acceptable).
I'd appreciate comments & any official guidelines. Thank you,
Jay Heiser
