The subsystem controls the amount of
data to be written. To control the
amount, the subsystem uses the
threshold specified by the Level 2
Threshold drop-down list.
The subsystem does not control the amount of

The subsystem performs “Sleep”
-”Wait” command retry.
If Donot Block (Volume Level) is enabled, the
subsystem will not perform “Sleep” -”Wait”
command retry.
If Donot Block (Volume Level) is disabled, the
subsystem will perform “Sleep” -”Wait”
command retry.
Enable

The subsystem does not perform
“Sleep” -”Wait” command retry.
The subsystem does not perform “Sleep” -”Wait”

Disable
If Level 1 Sleep is enabled, the
subsystem reports an SIM to the host
when the amount of used sidefile
capacity exceeds the “Sleep” -”Wait”
threshold.
If Level 1 Sleep is disabled, the
subsystem does not report an SIM to
the host when the amount of used
sidefile capacity exceeds the “Sleep”
-”Wait” threshold.
If Donot Block (Volume Level) is enabled, the
subsystem will not report an SIM to the host
when the amount of used sidefile capacity
exceeds the “Sleep” -”Wait” threshold.
If Donot Block (Volume Level) is disabled but
Level 1 Sleep is enabled, the subsystem will
report an SIM which indicates that the amount
of used sidefile capacity exceeds the “Sleep”
-”Wait” threshold, to the host.
If Donot Block (Volume Level) is disabled and
Level 1 Sleep is disabled, the subsystem will not
report an SIM to the host when the amount of
used sidefile capacity exceeds the “Sleep”
-”Wait” threshold.
Enable
Level 1
SIM
The subsystem does not report an
SIM to the host when the amount of
used sidefile capacity exceeds the
sleep wait threshold.
The subsystem does not report an SIM to the host
when the amount of used sidefile capacity
exceeds the sleep wait threshold.
