________________________________
I have a new fastt600 direct attached to 2 h80's
( aix 4.3.3.). The fast Best Practices Guide
talks about balancing LUNs across controllers,
but when I did this with a raid device, creating
a logical volume across 2 raid devices, tests
showed the system reading not from both raid devices
at the same time, but in round robin fashion.
Thruput was not terrible, but was not exceptional
either.
Anyone have any experience or suggestions
tuning the fastt600, or other fast devices ?
Thanks,
