two
dual-core
AMD
Opteron
microprocessors
in
single-width
models
or
up
to
four
dual-core
AMD
Opteron
microprocessors
in
double-width
models.
Depending
on
the
model,
the
blade
server
comes
with
either
one
or
two
microprocessors
installed.
An
optional
second
microprocessor
can
be
added
to
single-width
models
and
up
to
two
optional
microprocessors
can
be
added
to
double-width
models.
v
Integrated
network
support
All
of
the
blade
server
models
come
with
two
integrated
Broadcom
BCM5706S
Gigabit
Ethernet
controllers.
The
blade
server
double-width
types
also
have
two
additional
Broadcom
BCM5708S
Gigabit
Ethernet
controllers
in
the
MPE.
Both
controllers
support
connections
to
a
10-Mbps,
100-Mbps,
or
1000-Mbps

through
an
Ethernet-compatible
switch
module
in
the
BladeCenter
unit.
Both
controllers
also
support
Wake
on
LAN
®
technology.
v
I/O-expansion
The
blade
server
has
connectors
on
the
system
board
for
optional
expansion
cards
for
adding
more
network
communication
