Hardware Description
Introduction
The
ATCA
‐
46xx
Compute
Processing
Module
(CPM)
uses
a
number
of
hardware
components
to
implement
the
functions
required
of
an
ATCA
node.
The
major
hardware
components
in
the
ATCA
‐
46xx
CPM
are
as
follow:
•
Dual
E5
‐
2400
family
processors
mounted
in
FCLGA1356
sockets
•
Intel
C600
series
Platform
Controller
Hub
(PCH)
chip
that
supports
the
major
I/O
functionality
on
the
CPM.
•
Sockets
for
six
registered
DIMM
(RDIMM)
or
Load
Reduced
DIMM
(LRDIMM)
memory
modules
per
processor
or
twelve
modules
total.
Supported
RDIMMs
and
LRDIMMs
include
800,
1066,
or
1333
MHz
DDR3
modules
of
1,
2,
4,
8,
or
16
GB
capacity
for
a
total
of
up
to
96
GB
per
processor
or
192
GB
total
for
the
module.
•
Intel
I350
quad
Gigabit
Ethernet
controller
that
supports
two
GbE
Ethernet
ports
connected
to
the
Base
Interface
channels
and
GbE
Ethernet
ports
routed
to
the
CPM
front
panel
or
the
RTM
interface.
•
A
Mellanox
dual
40
GbE
controller
that
provides
two
40
Gb
Ethernet
ports
for
the
CPM
fabric
interface.
•
Heat
sinks
to
dissipate
heat
generated
by
the
E5
‐
2400
family
processors,
the
PCH,
and
the
40
GbE
controller.
•
Front
panel
connectors
for
serial,
video,
USB,
and
Ethernet.
•
Front
panel
LEDs
that
indicate
CPM
condition
and
status
information.
•
Zone
1
(P10),
Zone
2
(J20
and
J23),
and
Zone
3
(J30
and
J31)
connectors
to
the
backplane
and
RTM.
•
(Optional)
MXM
3.0
type
A
video
module
•
(Optional)
One
or
two
1.8”
microSATA
SSD
drives
mounted
in
an
MXM
DSSD
module
tray
•
(Optional)
One
or
two
eUSB
Flash
modules
