Blade
servers
The
BladeCenter
T
unit
supports
up
to
eight
high-performance
blade
servers.
Each
blade
server
is
an
enclosure
that
contains
microprocessors,
memory,
a
control
chip
set,
an
I/O
bus,
Ethernet
controllers,
hard
disk
drives
or
flash
drives,
and
user-interface
controls,
and
connectors
for
expansion
options.
The
blade
server
receives
its
power,
network
connection,
and
I/O
devices
(CD-ROM,
keyboard,
mouse,
and
video
ports,
USB
port,
remote
monitoring
port)
from
the
BladeCenter
T
unit,
reducing
the
number
of
cables
that
are
required.
Blade
server
expansion
options
Some
blade
servers
contain
connectors
for
options
that
add
capabilities
to
the
blade
server.
You
can
add
these
options
before
installing
the
blade
server
in
the
BladeCenter
T
unit.
Go
to
for
a
list
of
available
options
for
your
IBM
blade
server.
I/O
expansion
option
Some
blade
servers
have
connectors
for
adding
an
I/O
expansion
option,
such
as
an
IBM
BladeCenter
Fibre
Channel
Expansion
Card.
The
BladeCenter
T
unit
routes
network
communication
signals
from
the
I/O
expansion
option
to
I/O
modules
3
and
4
on
the
BladeCenter
T
unit.
The
I/O
expansion
option
is
attached
directly
to
the
blade
server
and
does
not
occupy
an
additional
blade
bay.
Note:
If
an
I/O
expansion
option
is
installed
on
any
blade
server,
I/O
modules
that
are
compatible
with
that
network
interface
must
be
installed
in
I/O-module
bays
3
and
4
on
the
BladeCenter
T
unit.
See
for
more
information.

expansion
unit
supports
up
to
two
hot-swap
SCSI
hard-disk
drives.
The

is
attached
directly
to
the
blade
server
and
occupies
an
additional
blade
server
bay.
PCI
I/O-expansion
Unit

Some
blade
servers
have
a
connector
for

unit
supports
up
to
two
