If "Enable" is selected for "Drive Tuning Parameter Setting", not only is the "Ordered Cut" value changed but the
"Throttle" value is changed as well. To keep the "Throttle" value unchanged, specify the current parameter displayed

Select "Enable" for "Drive Tuning Parameter Setting" and specify "Throttle".
"Throttle" is the proportion of the number of commands that is to be issued to a drive at
the same time to the maximum number of command issuance. It is not necessary to
change the default value for normal use. If a single RAID group is selected to start this
function, the value that is currently set in the ETERNUS DX is displayed. If multiple RAID
groups are selected to start this function and the same value is specified for all the RAID
groups in the ETERNUS DX, that value is displayed. If a RAID group with a different
"Throttle" exists in the ETERNUS DX, "100 %" is displayed.
100 % - 10 %
Select "Enable" for "Drive Tuning Parameter Setting" and specify "Ordered Cut".
"Ordered Cut" is the number of commands to optimize drive access processing (priority
control). When "Ordered Cut" is "x", the order is changed for every x commands based on
the priority settings of the commands. It is not necessary to change the default value for
normal use. If a single RAID group is selected to start this function, the value that is
currently set in the ETERNUS DX is displayed. If multiple RAID groups are selected to start
this function and the same value is specified for all the RAID groups in the ETERNUS DX,
that value is displayed. If a RAID group with a different "Ordered Cut" exists in the
ETERNUS DX, "0" is displayed.
