What
your
LS20
Type
8850
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
Disk
drive
support
The
blade
server
supports
up
to
two
2.5
inch
SCSI
disk
drives.
For
the
BladeCenter
T
unit,
the
SCSI
controller
is
able
to
interface
to
the
solid-state
flash
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
AMD
Opteron
microprocessors.
Depending
on
the
model,
the
blade
server
comes
with
either
one
or
two
microprocessors
installed.
For
models
equipped
with
one
factory-installed
microprocessor,
an
optional
microprocessor
can
be
added.
v
Integrated
network
support
The
blade
server
comes
with
two
integrated
dual
Gigabit
Ethernet
controllers.
Each
Ethernet
controller
has
an
interface
for
connecting
to
10/100/1000-Mbps
networks
through
an
Ethernet-compatible
switch
module
on
the
BladeCenter
unit.
The
blade
server
automatically
selects
between
10BASE-T
and
100/1000BASE-TX
environments.
Each
controller
provides
full-duplex
(FDX)
capability,
which
enables
simultaneous
transmission
and
reception
of
data
on
the
Ethernet
local
area
network
(LAN).
The
controllers
support
Wake
on
LAN
®
technology.
v
I/O
expansion
The
blade
server
comes
with
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
As
of
the
date
of
this
publication,
the
memory
bus
in
the
blade
server
supports
up
to
8
GB
of
system
memory,
typically
4
GB
per
microprocessor.
The
memory
controller
provides
support
for
up
to
four
industry-standard
2.6
V,
184-pin,
double-data-rate
(DDR1),
PC3200,
very
low
profile
(VLP),
registered
synchronous
dynamic
random-access
memory
(SDRAM)
with
error
correcting
code
(ECC)
DIMMs.
For
the
most
current
list
of
supported
DIMMs,
see
the
ServerProven
®
list
at
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
v
Light
path
diagnostics
The
light
path
diagnostics
feature
provides
light-emitting
diodes
(LEDs)
to
assist
in
isolating
problems
with
the
blade
server.
An
LED
on
the
blade
server
control
panel
is
lit
if
an
unusual
condition
or
a
problem
occurs.
If
this
happens,
you
can
look
at
the
LEDs
on
the
system
board
to
locate
the
source
of
the
problem.
v
Power
throttling
Each
blade
server
is
powered
by
two
BladeCenter
redundant
power-supply
modules.
By
enforcing
a
power
policy
known
as
power
domain
oversubscription,
the
BladeCenter
unit
can
share
the
power
load
between
two
power
modules
to
ensure
efficient
power
for
each
device
in
the
BladeCenter
unit.
This
policy
is
enforced
when
the
initial
power
is
applied
to
the
BladeCenter
unit
or
when
a
blade
server
is
inserted
into
the
BladeCenter
unit.
