For
details
on
the
design
of
control
domain,
root
domain,
and
I/O
domain
configurations,
see
the
Fujitsu
SPARC
M12
and
Fujitsu
M10/SPARC
M10
Domain
Configuration
Guide
.
Note
-
For
cases
of
CPU
module
expansion
after
the
installation
of
equipment
to
change
to
the
2-CPU
configuration,
the
recommended
configuration
is
one
with
four
root
complexes.
This
configuration
inherits
the
I/O
bus
configuration
and
mounting
rules
of
the
1-CPU
configuration.
Changing
the
configuration
into
one
with
eight
root
complexes
increases
the
maximum
number
of
mounted
PCI
cards.
However,
system
reconfiguration
is
required
because
the
I/O
bus
is
reconfigured.
If
an
Oracle
Solaris
10
environment
is
used
in
the
following
configurations,
apply
the
rules
for
Oracle
Solaris
11.
■
A
guest
domain
of
an
Oracle
Solaris
10
environment
is
configured
using
the
virtual
I/O
services
of
a
control
domain
or
the
root
domain
of
Oracle
Solaris
11.
■
An
Oracle
Solaris
10
zone
is
configured
on
an
Oracle
Solaris
11
domain.
If
there
are
plans
to
add
a
root
domain
or
I/O
domain
of
Oracle
Solaris
10
after
the
start
of
system
operation,
apply
the
rules
for
Oracle
Solaris
10.
2.1.2
Number
of
CPUs
and
Number
of
Root
Complexes
A
root
complex
consists
of
an
I/O
controller
mounted
on
a
processor
and
the
PCI
switches,
PCI
devices,
etc.
under
the
I/O
controller.
The
number
of
root
complexes
varies
depending
on
the
CPU
configuration,
and
the
maximum
number
of
mounted
PCI
cards
and
the
available
PCI
slots
vary
depending
on
the
number
of
root
complexes.
For
cases
of
CPU
module
expansion
after
the
installation
of
equipment
to
change
to
the
2-CPU
configuration,
if
the
I/O
bus
is
not
reconfigured,
apply
the
rules
for
the
1-CPU.
For
details
on
root
complexes,
see
2.2
Maximum
Number
of
Each
Type
of
Mounted
PCI
Card
and
Available
PCI
Slots
For
the
maximum
number
of
each
type
of
mounted
PCI
card
and
the
available
PCI
slots,
see
to
according
to
the
domain
OS
version.
■
"Maximum
Number
Mounted"
means
the
maximum
number
of
PCI
cards
that
can
be
mounted
in
the
SPARC
M12-2
and
the
PCI
expansion
unit.
The
numbers
in
(
)
indicate
the
slot
numbers
where
cards
can
be
mounted,

the
PCI
slots
