partitions
in
a
given
LPAR
cluster
should
be
given
the
same
range
of
values
so
that
WorkLoad
Manager
can
optimize
I/O
throughput
across
the
LPAR
cluster.
If
the
software
in
the
logical
partition
does
not
have
an
understanding
of
I/O
Priority
Queuing,
the
system
programmer
should
set
the
Minimum
and
Maximum
I/O
priorities
to
the
same
value.
The
value
chosen
will
be
assigned
to
that
logical
partition
as
a
constant
priority
value
relative
to
all
other
logical
partitions.
This
way
even
logical
partitions
that
do
not
employ
IRD
technologies
can
benefit
from
this
support.
