Subject: Fastt600 Performance
----------------------------------------------------------------------------
-- 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 ?
