Sharing
resources
among
the
blade
servers
The
IBM
Eserver
BladeCenter
T
Type
8720
or
8730
unit
provides
resources
that
are
available
to
all
blade
servers
at
all
times,
such
as
power
modules,
cooling,
system
management,
and
network
I/O
modules;
no
user
intervention
is
required.
Some
resources
are
selectable
for
use
by
a
single
blade
server
at
a
time,
such
as
the
CD-ROM
drive,
USB
port
units
(media
tray),
or
the
keyboard-video-mouse
(KVM)
module.
There
are
several
ways
to
select
resources
for
a
blade
server:
v
Each
blade
server
has
two
selection
buttons
on
the
front
of
the
blade:
CD
and
.
–
To
switch
the
keyboard,
video,
and
mouse
to
a
specific
blade
server,
press
the
button
on
that
blade
server.
–
To
switch
the
CD-ROM
and
USB
ports
to
a
specific
blade
server,
press
the
CD
button
on
that
blade
server.
The
management
module
immediately
assigns
the
resource
to
the
blade
server
requesting
it.
v
You
can
use
the
management
module
Web
interface
to
change
ownership
of
the
keyboard,
video,
and
mouse,
or
the
CD-ROM
drive,
and
USB
ports
(Blade
tasks
→
Remote
control).
v
You
can
press
keyboard
keys
in
the
following
sequence
to
switch
KVM
control
between
blade
servers:
NumLock
NumLock
blade_server_number
Enter
Where
blade_server_number
is
the
two-digit
number
for
the
blade
bay
in
which
the
blade
server
is
installed.
When
using
some
keyboards,
such
as
the
28L3644
(37L0888)
keyboard,
you
will
need
to
hold
down
the
Shift
key
while
entering
this
key
sequence.
Notes:
1.
It
can
take
up
to
20
seconds
for
the
operating
system
in
the
switched-to
blade
server
to
recognize
the
CD-ROM
drive,
and
USB
ports,
or
the
keyboard,
video,
and
mouse.
2.
If
you
install
Microsoft
Windows
2000
on
a
blade
server
while
it
is
not
the
current
owner
of
the
keyboard,
video,
and
mouse,
the
first
time
the
blade
server
requests
ownership
after
the
operating
system
has
been
installed,
it
can
take
up
to
1
minute
for
the
operating
system
to
recognize
the
devices
(this
is
a
one-time-only
occurrance).
3.
The
operating
system
in
the
blade
server
must
provide
USB
support
for
the
blade
server
to
recognize
and
use
the
keyboard,
mouse,
and
CD-ROM
drive.
The
BladeCenter
T
unit
uses
USB
for
internal
communication
with
these
devices.
4.
You
can
use
the
management-module
Web
interface
to
enable
or
disable
the
select
buttons
(Blade
tasks
→
Remote
control)
on
the
blade
servers.
5.
The
monitor
attached
to
the
BladeCenter
T
management
module
normally
shows
the
video
output
from
the
blade
server
that
is
the
current
owner
of
the
keyboard,
video,
and
mouse
(KVM).
When
there
is
no
actively
selected
video
from
any
blade
server,
the
video
from
blade
server
8
is
routed
to
the
management
module.
While
the
management
module
is
restarting,
there
is
temporarily
no
current
KVM
owner.
The
video
from
blade
server
8
displays
on
the
monitor
briefly
until
the
management
module
uses
its
NVRAM
values
