DR550
SSAM
Server
The
DR550
SSAM
Server
is
a
cost-effective,
high-performance,
space-efficient
server
that
uses
advanced
IBM
technology.
The
DR550
SSAM
Server
uses
the
™
microprocessor,
and
is
designed
for
use
in
LAN
clustered
environments.
The
DR550
SSAM
Server
is
a
member
of
the
symmetric
multiprocessing
(SMP)
UNIX
®
servers
from
IBM.
The
DR550
SSAM
Server
is
a
4-EIA
(4U),
19-inch
rack-mounted
server
that
is
configured
as
a
2-core
system
with
2.1
GHz
processors.
The
total
system
memory
installed
is
2048
MB.
The
DR550
SSAM
Server
includes:
v
Six
hot-plug
PCI-X
slots.

SCSI
controller.
v
Two
10/100/1000

Ethernet
controllers.
v
Eight
front-accessible
disk
bays
supporting
hot-swappable
disks.
(Two
are
populated
with
73
GB
Ultra3
10K
RPM
disk
drives.)
These
disk
bays
are
designed
to
provide
high
system
availability
and
growth
by
allowing
the
removal
or
addition
of
disk
drives
without
disrupting
service.
The
internal
disk
storage
is
configured
as
mirrored
disk
for
high
availability.
The
DR1
model
of
the
DR550
SSAM
Server
has
six
146GB
15K
RPM
internal
disk
drives
and
a
SCSI
RAID
controller.
To
diagnose
problems
with
the
DR550
SSAM
Server,
refer
to
the
Solving
a
problem
section
of
the
Serviceability
Increasing
service
productivity
means
the
system
is
up
and
running
for
a
longer
time.
The
DR550
SSAM
Server
improves
service
productivity
by
providing
the
functions
described
in
the
following
sections.
SSAM
Server
hardware
failures
v
Check
light
indicators.
v
Use
AIX
error
report
(
errpt
)
for
problem
determination.
v
Use
AIX
diagnostics
(
diag
command)
for
problem
determination.
v
Use
other
AIX
checkout
commands
for
problem
determination
(
lsdev,
lsvg,
lspv,
fget_config,
lssrc
,
etc.).
v
The
AIX
snap
command
creates
a
system
snapshot
for
support.
