The
System
x3950
and
System
x3950
E
server
The
IBM
®
System
x3950
Type
8872
server
is
a
3-U
1
-high,
high-performance
server.
It
is
ideally
suited
for
networking
environments
that
require
superior
microprocessor
performance,
efficient
asset
management,
flexibility,
and
large
amounts
of
reliable
data
storage.
The
System
x3950
E
server
comes
without
a
microprocessor
or
memory,
but
you
can
install
the
components
to
make
the
System
x3950
E
server
functionally
identical
to
the
System
x3950
server.
You
can
interconnect
System
x3950
and
System
x3950
E
servers
to
create
multi-node
configurations
using
two,
four,
or
eight
nodes,
for
up
to
32-way
operation.
A
System
x3950
server
must
serve
as
the
primary
node
in
the
multi-node
configuration.
Performance,
ease
of
use,
reliability,
and
expansion
capabilities
were
key
considerations
in
the
design
of
the
server.
These
design
features
make
it
possible
for
you
to
customize
the
system
hardware
to
meet
your
needs
today
and
provide
flexible
expansion
capabilities
for
the
future.
The
server
comes
with
a
limited
warranty.
For
information
about
the
terms
of
the
warranty

The
server
contains
IBM
Enterprise
X-Architecture
™
technologies,
which
help
increase
performance
and
reliability.
