What
your
blade
server
offers
The
design
of
the
blade
server
takes
advantage
of
advancements
in
memory
management
and
data
storage.
The
blade
server
uses
the
following
features
and
technologies:
v
Baseboard
management
controller
(BMC)
The
baseboard
management
controller
(BMC)
is
on
the
system
board
of
the
blade
server.
The
BMC
operates
as
the
service
processor
for
the
blade
server
and
performs
several
tasks,
including
the
following
functions:
–
Provides
RS-485
interfaces
to
the
management
module
–
Provides
support
for:
-
Intelligent
Platform
Management
Interface
(IPMI)
-
The
operating
system
-
Power
control
and
advanced
power
management
-
Reliability,
availability,
and
serviceability
(RAS)
features
-
Serial
over
LAN
(SOL)
v
Disk
drive
support
The
blade
server
supports
up
to
two
2.5-inch
small
form
factor
(SFF)
Serial
Attached
SCSI
(SAS)
hard
disk
drives.
v
IBM
Director
IBM
Director
is
a
workgroup-hardware-management
tool
that
you
can
use
to
centrally
manage
servers.
For
more
information,
see
the
IBM
Director
documentation
on
the
IBM
Director
CD.
v
Impressive
performance
using
the
latest
microprocessor
technology
The
blade
server
supports
up
to
two
Dual-Core
Intel
Xeon
processor
LV
microprocessors.
Depending
on
the
model,
the
blade
server
comes
with
either
one
or
two
microprocessors
installed.
In
models
that
come
with
one
factory-installed
microprocessor,
an
optional
second
microprocessor
can
be
added.
v
Integrated
network
support
The
blade
server
comes
with
an
integrated
Broadcom
BCM5704S
Dual
Gigabit
Ethernet
controller,
which
supports
connection
to
a
10-Mbps,
100-Mbps,
or
1000-Mbps
network
through
an
Ethernet-compatible
switch
module
in
the
BladeCenter
unit.
The
controller
supports
Wake
on
LAN
®
technology.
v
I/O-expansion
The
blade
server
has
connectors
on
the
system
board
for
an
optional
expansion
card,
such
as
the
Fibre
Channel
expansion
card,
for
adding
more
network
communication
capabilities
to
the
blade
server.
v
Large
system-memory
capacity
The
blade
server
supports
up
to
16
GB
of
system
memory.
The
memory
controller
provides
support
for
up
to
four
industry-standard
1.8
V,
240-pin,
double-data-rate
(DDR2-400),
PC3200,
registered
synchronous
dynamic
random-access
memory
(SDRAM)
with
error
correcting
code
(ECC)
DIMMs.
For
the
most
current
list
of
supported
DIMMs,
