commerce
applications
(IBM
WebSphere
®
Application
Servers,
WebSphere
Commerce
Server),
computational
nodes
(Linux
clusters,
rendering
farms),
and
workgroup
infrastructure
(Citrix
MetaFrame
terminal
serving,
Novell,
or
Microsoft

serving).
v
High
availability
and
ease
of
serviceability.
Blade
server
designs
include
high-availability
features
similar
to
those
found
in
conventional
rack
servers,
such
as
redundant
and
hot-swap
components
(even
the
hot
swapping
of
the
blade
servers
themselves).
Removing
a
server
for
maintenance
involves
simply
sliding
a
blade
out
of
the
BladeCenter
unit,
which
makes
a
policy
of
″
hot-spare
″
servers
effective
to
implement.
In
addition,
you
can
configure
blades
to
fail
over
to
one
another
in
the
event
of
a
failure.
v
Systems
management
and
deployment.
In
blade
servers,
integrated
systems
management
processors
monitor
the
status
of
blades
and
modules
all
at
once.
In
the
event
of
an
alert,
the
processors
can
signal
the
systems
management
software,
which
can
then
notify
the
administrator
by
or
pager
at
any
hour
of
the
day
or
night.
In
addition,
the
software
is
able
to
run
system
diagnostics
and
integrate
with
enterprise-wide
systems
management
software.
The
ability
to
slide
server
blades
in
and
out
of
the
BladeCenter
unit
makes
new
server
deployment
more
efficient.
When
you
insert
a
blade
into
an
open
bay,
it
is
connected
to
all
infrastructure
components
in
the
BladeCenter
unit.
There
is
typically
no
need
to
plug
multiple
cables
into
each
server
as
it
is
installed.
For
example,
instead
of
having
to
attach
a
KVM
cable,
power
cable,
Ethernet
cable,
and
systems
management
cable
per
server,
you
may
only
need
to
attach
one
of
each
cable
per
BladeCenter
unit,
which
contains
multiple
servers.
Even
if
you
decide
to
attach
a
second
set
of
cables
for
redundancy
you
still
have
to
attach
many
fewer
cables
than
is
needed
for
a
similar
configuration
of
standalone
servers.
Deployment
scenarios
The
IBM
®
BladeCenter
unit
can
be
deployed
to
support
a
variety
of
networking
goals
and
environments,
such
as:
v
Server
consolidation
The
IBM
BladeCenter
unit
can
be
used
by
organizations
with
multiple
server
locations
that
need
to
centralize
or
physically
consolidate
servers
to
increase
flexibility,
reduce
maintenance
costs,
and
reduce
human
resources.
v
E-business
infrastructure
The
IBM
BladeCenter
unit
can
be
used
by
companies
that
need
to
deploy
new
e-commerce
and
e-business
applications
and
infrastructure
quickly
to
minimize
time
to
market,
while
at
the
same
time
ensuring
flexibility,
scalability,
and
availability.
v
Enterprise
infrastructure
The
IBM
BladeCenter
unit
can
support
Enterprise
infrastructure
through:
File
and
print:
For
organizations
with
decentralized/departmental
file
and
servers
that
need
to
reduce
the
cost
of
ownership,
increase
reliability
and
provide
flexibility
for
growth.
Collaboration:
For
customers
needing
a
cost-effective
and
reliable
corporate
solution
for
e-mail,
calendar,
and
other
collaboration
capabilities.
v
High-performance
computing
The
IBM
BladeCenter
unit
can
be
used
by
customers
with
compute-intensive
applications
needing
highly
available
clustered
solutions
to
achieve
significantly
higher
degrees
of
scalability
and
performance,
all
managed
at
a
low
cost.
