I'm looking for best experiences ... how you folks have managed queue_depth of Linux (RHEL 6.3) on POWER.
This is an lpar backed by vSCSI boot & data volumes presented via a dual VIO setup.
. is it managed on the VIO hdiskX devices?
. or on the Linux lpar, if so ... where? in /etc/modprobe.d/?
. or where else on the Linux lpar? /dev/mapper device or /dev/sdX device?
. which setting takes precedences, highest or lowest value?
