Queue depth setting on solaris 10 server
Hi,
We are having performance issues on some of our database servers.
The SAN team want to the know the optimum setting for queue depth setting for the HBA card.
Currently i see the following setting:
# echo "sd_max_throttle/D" |mdb -k
sd_max_throttle:
sd_max_throttle:256
BUt, I dont see max_throttle values set in /etc/system file, question is where is the above command picking up the values ? Is the Queue depth set ?
The HBA card vendor is Qlogic.
# luxadm -e port
/devices/pci@0,600000/pci@0/pci@8/pci@0,1/SUNW,qlc@1/fp@0,0:devctl CONNECTED
/devices/pci@0,600000/pci@0/pci@9/SUNW,qlc@0/fp@0,0:devctl
