cr-delay Min:0
Max:63
Default:0
Description: Specifies a
count of milliseconds after
which an interrupt response
is generated if the cr-count
has not been satisfied. This
value is set to 0 to disable
the Coalesce Response
feature as default.
cr-delay Min:0
Max:63
Default:0
Description: Specifies a
count of milliseconds after
which an interrupt response
is generated if the cr-count
has not been satisfied. This
value is set to 0 to disable
the Coalesce Response
feature as default.
Setting this value
can minimize
CPU utilization by
reducing the
number of
interrupts that the
driver generates
to the operating
system.
cr-count Min:1
Max:255
Default:1
Description: Specifies a
count of I/O completions
after which an interrupt
response is generated. This
feature is disabled if cr-
delay is set to 0.
cr-count Min:1
Max:255
Default:1
Description: Specifies a
count of I/O completions
after which an interrupt
response is generated. This
feature is disabled if cr-delay
is set to 0.
The parameter
setting is often
determined by
your OEM. This
parameter sets
the number of
I/Os to be queued
in the operating
system’s driver
before an
interrupt is
initiated. The
driver default
settings are
roughly a 1:1 I/O
to interrupt ratio.
If you change this
parameter,
performance
varies per
application.
link-speed 0 = auto select
1 = 1 Gigabaud
2 = 2 Gigabaud
4 = 4 Gigabaud
Default: 0
Description: Sets the link
speed setting for initializing
the FC connection.
link-speed 0 = auto select
1 = 1 Gigabaud
2 = 2 Gigabaud
4 = 4 Gigabaud
Default: 0
Description: Sets link speed.
This variable can
be changed to a
specific link
speed to optimize
the link
initialization
process for a
specific
environment.
