Reliability,
availability,
and
serviceability
features
Three
of
the
most
important
features
in
server
design
are
reliability,
availability,
and
serviceability
(RAS).
These
RAS
features
help
to
ensure
the
integrity
of
the
data
that
is
stored
in
the
blade
server,
the
availability
of
the
blade
server
when
you
need
it,
and
the
ease
with
which
you
can
diagnose
and
correct
problems.
The
blade
server
has
the
following
RAS
features:
v
Advanced
Configuration
and
Power
Interface
(ACPI)
v
Automatic
error
retry
or
recovery
v
Automatic
server
restart
v
Built-in
monitoring
for
temperature,
voltage,
hard
disk
drives,
and
flash
drives
v
Chipkill
memory
for
dual
inline
memory
modules
(DIMMs)
with
a
capacity
of
1
GB
or
greater
v

and
messages
v
ECC

on
the
L2
cache
v

support
v
Light

v
Predictive

v
Service
processor
that
communicates
with
the
management
module
to
enable
remote
blade
server
management
v
SDRAM
with
serial
presence
detect
(SPD)
and
vital
product

(VPD)
v
System

v
VPD
(includes

for
easier
remote
viewing)
v

capability
IBM
Director
With
IBM
Director,
a
network
administrator
can
perform
the
following
tasks:
v
View
the
hardware
configuration
of
remote
systems,
in
detail
v
Monitor
the
usage
and
performance
of
critical
components,
such
as
microprocessors,
disks,
and
memory
v
Centrally
manage
individual
or
large
groups
of
IBM
and
non-IBM
Intel
®
-processor-based
servers,
desktop
computers,
workstations,
and
mobile
computers
on
a
variety
of
platforms
1.
Service
availability
will
vary
by
country.
Response
time
will
vary
depending
on
the
number
and
nature
of
incoming
calls.
