What
your
IBM
BladeCenter
JS20
Type
8842
offers
Your
blade
server
is
designed
to
take
advantage
of
advancements
in
memory
management
and
data
storage.
Your
blade
server
includes:
v
IBM
Director
IBM
Director
is
a
workgroup-hardware-management
tool
that
you
can
use
to
centrally
manage
xSeries
®
servers.

v
Impressive
performance
using
the
latest
microprocessor
technology
Your
blade
server
supports
two
IBM
PowerPC
970
microprocessors
and
comes
with
two
microprocessors
installed.
Together,
these
two
microprocessors
enhance
performance.
With
two
microprocessors,
your
blade
server
can
operate
as
a
symmetric
multiprocessing
(SMP)
server.
With
SMP,
certain
operating
systems
and
application
programs
can
distribute
the
processing
load
between
the
microprocessors.
To
use
SMP,
obtain
an
SMP-capable
operating
system.

supported
operating
systems
and

v
Integrated
network
environment
support
Your
blade
server
comes
with
one
integrated
dual-port
Gigabit
Ethernet
controller.
Each
Ethernet
controller
port
has
an
interface
for
connecting
to
10/100/1000-Mbps
networks
through
an
Ethernet-compatible
switch
module
on
the
BladeCenter
unit.
The
switch
module
automatically
selects
between
10BASE-T
and
100/1000BASE-TX
environments.
Each
controller
port
provides
full-duplex
(FDX)
capability,
which
enables
simultaneous
transmission
and
reception
of
data
on
the
Ethernet
local
area
network
(LAN).
The
controller
supports
Wake
on
LAN
®
technology.
v
I/O
expansion
Your
blade
server
comes
with
two
connectors
on
the
system
board
for
an
optional
I/O
expansion
card
for
adding
more
network
communication
capabilities
to
the
blade
server.
v
Large
system
memory
The
memory
bus
in
your
blade
server
supports
up
to
4
GB
of
system
memory.
The
memory
controller
provides
support
for
up
to
four
industry-standard
2.5
V,
184-pin,
double-data-rate
(DDR),
PC2700,
registered
synchronous
dynamic
random-access
memory
(SDRAM)
with
error
correcting
code
(ECC)
dual
inline
memory
modules
(DIMMs).
For
the
most
current
list
of
supported
DIMMs,
see
the
ServerProven
®
list
at
http://www.ibm.com/pc/us/compat/.
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.
