Chapter

System
overview
This
chapter
provides
an
overview
of
the
IBM
®
System
Cluster
1350
software
components,
hardware
components,
and
related
documentation.
The
Cluster
1350
uses
two
types
of
cabinets:
primary
and
expansion.
A
cabinet
is
called
primary
if
it
contains
the
management
node
and
console
monitor.
An
expansion
cabinet
can
contain
storage
nodes
or
mass-storage
devices
as
well
as
computing
nodes,
called
cluster
nodes;
it
does
not
contain
a
management
node
or
a
console.
The
cluster
may
consists
of:
v
One
or
more
racks.
v
From
four
to
1024
cluster
nodes.
The
nodes
are
configured
to
run
customer
applications
or
provide
other
services
required
by
the
customer,
such
as
file
server,
network
gateway,
or
storage
server.
v
One
management
node
(System
x3650
or
System
x3655)
for
cluster
systems
management
(CSM)
and
administration.
v
A
management
Ethernet
VLAN
that
is
used
for
secure
traffic
for
hardware
control.
The
management
Ethernet
VLAN
is
used
for
management
traffic
only.
It
is
logically
isolated
for
security
using
the
VLAN
capability
of
the
Cisco
Ethernet
switches,
and
it
is
only
accessible
from
the
management
node.
The
cluster
VLAN
and
management
VLANs
share
the
same
physical
switches.
v
A
cluster
VLAN
used
for
other
management
traffic
and
user
traffic.
Switches
integrated
with
the
cluster
are
used
for
the
management
Ethernet
VLAN
and
the
cluster
Ethernet
VLAN.
v
Service
processor
networks.
All
nodes
in
the
cluster
are
connected
through
serial
service
processors
(such
as
the
System
x3650).
The
first
node
in
a
serial
connection
must
have
a
management
node,
which
is
connected
through
the
Ethernet
to
the
management-Ethernet
VLAN.
v
A
terminal
server
network
for
remote
or
local
console.
Optionally,
the
customer
might
elect
to
include
an
additional
network.
v
A
high-performance
Myrinet
2000
cluster
interconnect,
an
additional
Gigabit
Ethernet,
or
an
InfiniBand
switch.
v
The
customer
can
elect
to
configure
a
subset
of
cluster
nodes
with
additional
external
storage.
This
can
be
a
Fibre
Channel
solution.
v
A
supported
distribution
of
the
Linux
operating
system.
v
Cluster
systems-management
software,
such
as
CSM.
The
Cluster
1350
supports
a
maximum
of
1024
nodes
in
addition
to
the
one
required
System
x3650
(or
the
System
x3655
management
node
for
64-bit
processing
environments)
management
node.
All
nodes
must
run
one
of
the
following
Linux
versions:
v
Red
Hat
Enterprise
Linux
(RHEL),
version
4
for
AMD
or
EMT
(32-bit
or
64-bit)
v
RHEL,
version
4
for
AMD
or
EMT
(64-bit)
v
SUSE
LINUX
Enterprise
Server
(SLES),
version
9
for
AMD
or
EMT
(64-bit)
v
SLES,
version
10
v
Linux
Cluster
Installation
Tool
(LCIT),
version
5.0
