CHAPTER

1

Sun Server X2-4 Service Manual
Overview

This chapter provides an overview of the Sun Server X2-4.

It contains the following topics:

■ Section 1.1 “System Overview” on page 1-1

■ Section 1.2 “Server Front Panel Features” on page 1-9

■ Section 1.3 “Server Back Panel Features” on page 1-10

■ Section 1.4 “Performing Service Related Tasks” on page 1-11

1.1 System Overview

Oracle’s Sun Server X2-4 is a 3 rack unit (RU) rackmount server that uses the Intel
Xeon E7 platform. This section describes the major features, components, and
capabilities of the server.

1.1.1 Intel Xeon E7 Platform

The Intel Xeon E7 platform is based on the Intel Xeon Processor E7-4800 Series and
uses the Intel 7500 Chipset I/O hub (IOH) as its primary chipset. The platform uses
the Intel QuickPath Interface (QPI), a high-speed, differentially signaled,
point-to-point interface that forms a communication fabric among the processors
(CPUs) and IOHs in the system.

The Sun Server X2-4 uses two Intel 7500 Chipset I/O hubs, each connected to two of
the four CPUs. One of these I/O hubs is designated the legacy I/O hub and has a
connection to the Intel I/O Controller Hub 10 (ICH10) southbridge component.

1.1.2 Block Diagrams

FIGURE 1-1 shows a block diagram for a Sun Server X2-4 with four CPUs.

FIGURE 1-2 shows a block diagram for a Sun Server X2-4 with two CPUs.

Note – In the diagrams, the PCIe SAS/RAID Controller is shown as installed in Slot

2. If a particular SAS/RAID Controller has specific cooling requirements, it might
have to be installed in Slot 4. For information about cooling requirements, refer to the
Sun Server X2-4 Product Notes.

FIGURE 1-1 Four CPU Block Diagram

1-2 Sun Server X2-4 Service Manual • April 2013

FIGURE 1-2 Two CPU Block Diagram

1.1.3 Processors (CPUs)

The Sun Server X2-4 supports two or four processors (CPUs), as shown in FIGURE 1-1
and FIGURE 1-2. The two-CPU configuration must have CPUs (with heatsinks) in
sockets 0 and 2 and heatsink filler panels installed in sockets 1 and 3.

In a two-CPU configuration, all three QPI interconnects and both CPUs must be
operational. The four-CPU configuration offers a greater level of resiliency with
redundant QPI interconnects that allow working CPUs to route around a disabled
CPU as the system starts.

Chapter 1 Sun Server X2-4 Service Manual Overview 1-3

Features of each Intel Xeon Processor E7-4800 Series include:

■ Up to ten cores with Hyper-Threading (two threads/core)

■ Up to 30MB shared last level cache

■ 32nm process technology

■ Two integrated memory controllers with four Intel Scalable Memory Interconnects

(SMI channels)

■ Supports speeds of DDR3-1067 MT/s via an Intel 7510 Scalable Memory Buffer

■ Four full-width, bidirectional Intel QuickPath interconnects (QPI links)

■ 6.4 GT/s (12.8 GB/s per direction)

■ Automatic self-healing by degrading to half-width or quarter-width link

operation

■ CPU Thermal Design Power (TDP) of 105W or 130W

Note – For more information about Intel QuickPath Interconnects, refer to Weaving

High Performance Multiprocessor Fabric from Intel Press at

http://www.intel.com/intelpress/sum_qpi.htm.

1.1.4 Memory

Each CPU in the Sun Server X2-4 has four SMI channels leading to Intel 7510 Scalable
Memory Buffers (located on two memory risers). Each memory buffer has an SMI
link to the CPU and two DDR3 interfaces. Each SMI interface can operate at speeds
of 6.4 GT/s, which correspond to DDR3 operation at 1067 MT/s. From the CPU to
the Intel 7510 Scalable Memory Buffer, the SMI interface supports 11 lanes (9 data + 1
CRC + 1 spare). From the Intel 7510 Scalable Memory Buffer to the CPU, the SMI
interface supports 14 lanes (12 data + 1 CRC + 1 spare). The CPU retries memory
transactions that incur a CRC error. For persistent errors, the SMI link has spare lanes
for automatic self-healing.

The system supports a maximum of eight memory risers (4 CPU configuration) or
four memory risers (2 CPU configuration). Each riser houses 8 DIMM slots for the
four DDR3 channels. The system can operate with 0, 2, 4, 6 or 8 DIMMs on a given
riser. For maximum performance, install at least two ranks of DIMMs on every
available DDR3 channel (for example, 4 DIMMs per riser with two risers per CPU).

Each of two memory controllers in a CPU operates its two SMI channels as a
lock-step pair. The memory controller treats each pair of DDR3 channels behind the
two memory buffers as a 144-bit-wide DRAM interface. As a result, the DIMMs must
be installed in pairs, with identical DIMMs in each pair.

The DDR3 interfaces include the following features:

1-4 Sun Server X2-4 Service Manual • April 2013

■ Accommodates x4 and x8 Single-Rank, Dual-Rank, Quad-Rank RDIMMs

■ Supports up to 2 RDIMMs per DDR3 channel (8 DIMM slots per memory riser)

■ DDR3 speed: 1067 MT/s or 978 MT/s (dictated by SMI speeds of CPUs)

■ DRAM Technology: 2 or 4 Gb die, 1.35-volt or 1.5-volt operation

■ DIMM Capacity: 4, 8, 16 GB (16 GB with Quad-Rank DIMMs only)

■ Currently supported DIMMs are PC3L RDIMMs, dual-rank in 4-, 8-, and

quad-rank 16-GB sizes

For more information about CPUs, memory risers, and memory layout, including
guidelines for populating memory risers and DIMMs, see Section 4.1 “Servicing

Memory Risers and DIMMs (CRU)” on page 4-1.

FIGURE 1-3 shows the architecture of the server memory.

FIGURE 1-3 Memory Architecture

1.1.5 Cooling

The Sun Server X2-4 is cooled from front to back. Cooling occurs in two areas of the
chassis, separated by a plastic dividing wall. In the power supply cooling zone, fans
at the back of the power supplies cool the drive bays as well as the power supplies,

Chapter 1 Sun Server X2-4 Service Manual Overview 1-5

by drawing air into the depressurized zone at the right of the chassis. In the main
cooling zones, six 92-mm high-performance fans, arranged in two rows for
redundancy, cool the motherboard, memory risers, and I/O cards. The motherboard
is divided into three zones and each pair of fans is separately regulated to cool that
zone. Since the main cooling zones are pressurized, it is important to maintain the
seal of the dividing wall so that the power supply units can draw air through the
drive bay.

The unrestricted airflow over the motherboard minimizes system noise. Dividing the
cooling into zones allows for greater use of system resources, since each zone can
operate independently at its highest efficiency.

FIGURE 1-4 shows the cooling zones.

1.1.6 Input/Output (I/O)

For internal storage, the server chassis provides:

1-6 Sun Server X2-4 Service Manual • April 2013

■ Six 2.5-inch drive bays, accessible through the front panel. The supported drive

interfaces for each bay depend on the host bus adapter (HBA) chosen.

■ An optional slot-loading DVD+/-RW drive on front of the server, below the drive

bays. This SATA DVD connects to a USB-SATA bridge, so that is appears to the
system software as a USB storage device.

■ One internal high-speed USB port on the motherboard. This port can hold a USB

flash device for system booting.

In addition, the service processor can present virtual USB storage devices to the
system.

The ICH10 southbridge on the motherboard provides six built-in SATA2 (3-Gbit/s)
ports, accessible through two SAS4I connectors (Port 0-3 and Port 4-5). When
configured with any 2.5-inch SAS drives, the system must be equipped with one PCI
Express (PCIe) Gen-2 internal HBA card to support the front 2.5-inch drive bays.

Each offered PCIe Gen-2 HBA has 8 SAS2/SATA2 internal ports accessible through
two SAS4I connectors (Port 0-3 and Port 4-7). Since the drive cage has only six bays,
Port 6-7 of an internal HBA are not used in this system.

With an internal SAS-2 HBA card installed in a PCIe slot, the six bays can handle any
combination of supported SAS and SATA hard disk drives (HDDs) and solid-state
drives (SSDs). If the disk backplane is connected to the built-in ICH10 SATA-2
controller rather than an HBA card, only SATA storage devices will operate. (When a
RAID volume is configured on the HBA card, the drive bays for the RAID members
must hold the same type of storage device.)

■ ESD mat and grounding strap

You might also need a system console device, such as one of the following:

■ PC or workstation with RS-232 serial port

■ ASCII terminal

■ Terminal server

■ Patch panel connected to a terminal server

2.3 Performing Electrostatic Discharge and
Static Prevention Measures

Electrostatic discharge (ESD) sensitive devices, such as the PCIe cards, hard drives,
CPUs, and memory cards, require special handling.

Caution – Circuit boards and hard drives contain electronic components that are

extremely sensitive to static electricity. Ordinary amounts of static electricity from
clothing or the work environment can destroy the components located on these
boards. Do not touch the components along their connector edges.

Caution – You must disconnect AC power cords to both power supplies before

servicing some of the components documented in this guide.

2.3.1 Using an Antistatic Wrist Strap

Wear an antistatic wrist strap when handling components such as disk drive
assemblies, circuit boards, or PCIe cards. When servicing or removing server
components, attach an antistatic strap to your wrist and then to a metal area on the
chassis. Following this practice equalizes the electrical potentials between you and
the server.

Chapter 2 Preparing to Service the Sun Server X2-4 2-3

Note – An antistatic wrist strap is not shipped with the servers. However, antistatic

wrist straps are included with customer-replaceable units (CRUs), field-replaceable
units (FRUs), and optional components.

2.3.2 Using an Antistatic Mat

Place ESD-sensitive components such as printed circuit boards on an antistatic mat.
You can use the following items as antistatic mats:

■ Antistatic bag used to wrap a replacement part

■ ESD mat (orderable from Oracle)

■ A disposable ESD mat (shipped with some optional system components)

2.4 Positioning the Server for Maintenance

To remove and replace components in the Sun Server X2-4, you must extend the
server to the maintenance position.

▼ Extend the Server to the Maintenance Position

1. Verify that no cables will be damaged or will interfere when the server is

extended.

Although the cable management arm (CMA) that is supplied with the server is
hinged to accommodate extending the server, you should ensure that all cables
and cords are capable of extending.

2. From the front of the server, release the two slide release latches (

Squeeze the green slide release latches to release the slide rails.

Servicing CRU Components That
Require Server Power Off

This chapter describes how to service customer-replaceable units (CRUs) that require
you to power down the system before servicing.

It contains the following topics:

■ Section 4.1 “Servicing Memory Risers and DIMMs (CRU)” on page 4-1

■ Section 4.2 “Servicing PCIe Cards (CRU)” on page 4-17

■ Section 4.3 “Servicing the DVD Drive and DVD Driver Filler Panel (CRU)” on

page 4-24

■ Section 4.4 “Servicing the System Lithium Battery (CRU)” on page 4-27

4.1 Servicing Memory Risers and DIMMs
(CRU)

Caution – These procedures require that you handle components that are sensitive

to static discharge. This sensitivity can cause the component to fail. To avoid damage,
ensure that you follow antistatic practices as described in Section 2.3 “Performing

Electrostatic Discharge and Static Prevention Measures” on page 2-3.

When replacing or upgrading a DIMM on the server you should consider the
following:

■ Physical layout of the CPUs, memory risers, and DIMMs

See Section 4.1.1 “CPUs, Memory Risers, and DIMMs Physical Layout” on

page 4-2.

4-1

■ Memory riser population rules

See Section 4.1.2 “Memory Riser Population Rules” on page 4-3.

■ Memory riser DIMM population rules

See Section 4.1.3 “Memory Riser DIMM Population Rules” on page 4-4.

■ Rules for installing DIMMs across memory risers

See Section 4.1.4 “Memory Performance Guidelines” on page 4-5.

■ DIMM rank classifications labels

See Section 4.1.6 “Supported DIMMs” on page 4-7.

■ Instructions for installing a DIMM

See “Install Memory Risers and DIMMs” on page 4-13.

4.1.1 CPUs, Memory Risers, and DIMMs Physical
Layout

The physical layout of the CPUs, memory risers, and DIMMs is shown in FIGURE 4-1
and FIGURE 4-2.

4-2 Sun Server X2-4 Service Manual • April 2013

FIGURE 4-1 CPU and Memory Riser Layout

4.1.2 Memory Riser Population Rules

Note – Only memory risers that are labeled “V2 Memory Riser” are supported in the

Sun Server X2-4. Before installing memory risers in the server, ensure that the
memory riser contains this label.

The system firmware checks if the installed CPUs are for the Sun Server X2-4. The
system firmware raises a fault for memory risers whose model belongs with the other
family of CPUs.

The memory riser population rules for the Sun Server X2-4 are as follows:

1. A maximum of two memory risers (numbered MR0 and MR1) are supported per

CPU, thus allowing up to eight memory risers in a 4-CPU system, or up to four
memory risers in a 2-CPU system.

Chapter 4 Servicing CRU Components That Require Server Power Off 4-3

2. Each memory riser slot in the server chassis must be filled with either a memory

riser or filler panel, and each memory riser must be filled with DIMMs and/or
DIMM filler panels. For example, in 2-CPU systems, empty CPU sockets (P1 and
P3) must have associated memory riser slots populated with two riser filler panels
per CPU.

3. Performance-oriented configurations should be configured with two memory

risers per CPU. In configurations that do not require two memory risers per CPU,
the following guidelines should be followed:

■ First populate riser slot MR0 for each CPU, starting with the lowest numbered

CPU (P0).

■ The populate riser slot MR1 for each CPU, starting with the lowest numbered CPU

(P0).

FIGURE 4-2 Memory Riser DIMMs Physical Layout and Population Order

4.1.3 Memory Riser DIMM Population Rules

The memory riser DIMM population rules for the Sun Server X2-4 are as follows:

1. Maximum memory operating speed is 1066 MHz. This also applies to supported

DIMMs rated for higher speeds.

2. Supported DIMMs include single-, dual-, or quad-rank 4 GB, 8 GB, 16 GB and 32

GB JEDEC˘2013standard, DDR3 low voltage ECC RDIMMs.

3. All DIMMs on a CMOD must be the same density and organization.

4-4 Sun Server X2-4 Service Manual • April 2013

Note – Do not mix dual-rank 16 GB DIMMs with quad-rank 16 GB DIMMs on a

CMOD. Mixing DIMMs of different rank or density degrades performance.

■ Single-rank DIMMs (marked 1Rx8) and dual-rank DIMMs (marked 2Rx4) do

not include heat spreaders.

■ Quad-rank DIMMs are marked 4Rx4 and include heat spreaders. DIMMs with

heat spreaders have two U-shaped metal clips on the top of the DIMM.

4. Each memory riser supports up to 8 DIMMs, with a maximum 64 DIMMs for a

4-socket Sun Server X2-4.

5. DIMM slots are color coded with the following population order:

■ Blue

■ White

■ Black

■ Green

6. DIMM slots must be populated in matching pairs of identical DIMMs (from the

same memory kit) within a processor.

The recommended DIMM population order, as depicted in

■ D0/D4

■ D2/D6

■ D1/D5

■ D3/D7

7. Install quad-rank DIMMs before dual-rank DIMMs on the same riser. Specifically,

a DRAM channel with both rank types must have the quad-rank DIMM in the
D0/D4 or D2/D6 slot.

Note – When a mixed quad-rank DIMM and dual or single rank DIMM are on the

same memory riser, the quad-rank DIMM should be installed in slot0 of each
channel.

4.1.4 Memory Performance Guidelines

Meeting these guidelines will provide the best system performance. Guidelines are
listed in decreasing importance.

FIGURE 4-2 is:

1. Provide some DIMMs on every memory riser.

Chapter 4 Servicing CRU Components That Require Server Power Off 4-5

2. Provide DIMMs on every DRAM channel (at least 4 DIMMs per memory riser).

3. For each CPU, have equal total gigabytes on the MR0 and MR1 risers. Memory

bandwidth is 5% higher when all pairs of risers have balanced capacity.

4. Spread the memory capacity evenly across the CPUs so the operating system can

distribute large memory tasks better.

5. Avoid mixing dual-rank and quad-rank DIMMs in the same memory riser.

4.1.4.1 Recommended Memory Placement

For the Sun Server X2-4, the operating speed of the DIMMs does not decrease as
more DIMMs are installed. For best memory performance, follow these simple
guidelines to add or replace DIMMs in the server. Use one or more sizes of DIMMs,
with an even number of DIMMs of each size.

1. Using the largest-capacity DIMMs, add two DIMMs per riser, starting at P0/MR0,

continuing through P3/MR1, and then beginning again at P0/MR0 if necessary,
until all of the largest-capacity DIMMs are placed.

For installations with one DIMM size, all DIMMs will be placed in this step. For
installations with additional DIMMs of different sizes, continue to the next
guideline step.

If you are adding or replacing quad-rank (16GB) DIMMs, they can be installed
only in D0/D4 slots or D2/D6 slots, or else in DRAM channels where those slots
already contain 16GB DIMMs.

2. Using DIMMs of the next largest capacity, add two DIMMs per riser, starting with

risers with the fewest DIMMs and proceeding from P0/MR0, continuing through
P3/MR1, and then beginning again at P0/MR0 if necessary, until there are no
more DIMMs of this size, or all risers have four DIMMs.

As long as any riser has fewer than four DIMMs, keep repeating this step with the
DIMMs of decreasing capacity. When all risers have four DIMMs, continue to the
next guideline step.

3. Using DIMMs of the next largest capacity, add two DIMMs per riser to risers with

the least total gigabytes. Start from P0/MR0, continuing through P3/MR1, and
then begin again at P0/MR0 is necessary.

Repeat guideline step 3 with all remaining DIMMs, in decreasing order of DIMM
capacity, until all DIMMs are placed.

4-6 Sun Server X2-4 Service Manual • April 2013

4.1.5 DIMM Fault Isolation

The eight DIMMs supported on each memory riser card in the Sun Server X2-4 are
divided into two logical DDR3 channels. The first logical channel contains DIMMs
installed in slots D0, D1, D4 and D5. The second logical channel contains DIMMs
installed in slots D2, D4, D6 and D7.

When one or more DIMMs within a logical DDR3 channel are faulted, all four
DIMMs within that logical channel will be disabled by BIOS on subsequent boots.
This isolates the faulty component from the system to ensure that proper operation is
not compromised by the presence of the faulty component.

4.1.6 Supported DIMMs

Initially supported DIMMs for the Sun Server X2-4 are PC3L-type RDIMMs, which
are DDR3 low-voltage DIMMs.

TABLE 4-1 Supported DIMM Size and Organization

4.2 Servicing PCIe Cards (CRU)

This section describes how to remove and install PCIe cards.

For the location of the PCIe slots, see Section 1.3 “Server Back Panel Features” on

page 1-10.

4.2.1 PCIe Card Configuration Rules

The server supports up to ten low-profile PCIe 2.0 cards. Refer to the Sun Server X2-4
Product Notes for details about supported PCIe cards, along with card quantity and
slot restrictions.

The following PCIe card slots are available on the server:

■ Slots 0 and 9: x4 electrical interface

■ Slots 1, 2, 4, 6, 7, and 8: x8 electrical interface

■ Slots 3 and 5: x8 or x16 electrical interface (x16 connector)

Note – Slots 3 and 5 operate as x16 interfaces only when an x16 capable card is

installed and the adjacent slot (4 or 6) is unpopulated.

To determine the slot in which to install a PCIe card, follow these guidelines:

■ First consider any cooling considerations that require a card to be installed in a

certain slot. For information about cooling considerations for PCIe cards, refer to
the Sun Server X2-4 Product Notes.

■ If your configuration includes an internal SAS/SATA Host Bus Adapter (HBA),

see if it has an integrated battery pack. Install a battery-backed internal HBA in
slot 4, for best cooling; otherwise, put the simpler, battery-less SAS/SATA HBA in
slot 2.

■ For high bandwidth cards, install the cards so that the load on the server is

balanced between the server ’s two I/O hubs (IOH), each of which connects to five
of the available PCIe slots. (IOH0 connects to slots 0–4 and IOH1 to slots 5–9.)
Avoid slots 9 and 0 for high-bandwidth cards since those are the x4 slots. Balance
the load as follows:

– IOH0 (which connects to slots 0–4), might already be using some bandwidth for

the ICH10 southbridge devices, so install the first high-bandwidth card in one
of slots 5–8.

Chapter 4 Servicing CRU Components That Require Server Power Off 4-17

– Install the next high-bandwidth card in one of slots 1–4. (If an internal HBA is

already installed in slot 0–4, skip this step and install the next card in another of
slots 5–8.)

– Continue to alternate the high-bandwidth cards between slots 1–4 and 5–8.

■ Install lower-speed cards (for example, 1-Gbit/s Ethernet and 8-Gbit/s Fibre

Channel adapters) in any remaining slots, since these cards perform well in any
location, including the x4 slots, 0 and 9.

4.2.2 PCIe Cards With Bootable Devices

If the server has several PCIe cards installed that provide bootable devices, disable
the Option ROM on the PCIe slots not used for booting so that resources are
available for the slots used for booting. By default, the BIOS enables Option ROMs
for PCIe slots 2 and 4, and the four Gigabit Ethernet ports. Refer to “Configure

Option ROM Settings” on page 7-21 for information about disabling Option ROM.

4.2.3 Avoiding PCI Resource Exhaustion Errors

With several Sun x4 PCI Express Quad Gigabit Ethernet Low Profile Adapter PCIe
cards (4446A-Z-N or X4446A-Z-N) installed in server slots 0 through 4, or even one
of these cards installed in slots 5 through 9, BIOS might log a "PCI resource
exhaustion" event. This error occurs because BIOS allocates 8 Kbytes of I/O space for
each of the Quad Gigabit Ethernet cards (and only 4 Kbytes of I/O space for a typical
card).

The following is a common form of the error that might be logged:

6491 Tue Dec 7 14:19:57 2010 IPMI Log minor
ID = a5a9 : 12/07/2010 : 14:19:57 : System Firmware Error:
sensor number
=0x00 : PCI resource exhaustion: Bus 147 Device 0 Func 0
6490 Tue Dec 7 14:19:57 2010 IPMI Log minor
ID = a5a8 : 12/07/2010 : 14:19:57 : System Firmware Error:
sensor number
=0x00 : PCI resource exhaustion: Bus 147 Device 0 Func 1

To eliminate the "PCI resource exhaustion" event, change the BIOS settings to disable
I/O allocation for any slot where the Quad Gigabit Ethernet card is installed. Refer to

Section 7.8 “Performing Common BIOS Procedures” on page 7-11 for instructions on

how to access the BIOS Setup Utility in order to disable I/O allocation from the
PCIPnP menu. The exception to this workaround is that if PXE network booting will
use a Quad Gigabit Ethernet card, you should leave I/O allocation enabled for that
slot.

4-18 Sun Server X2-4 Service Manual • April 2013

Since BIOS does not allocate I/O space for empty slots, maximizing the number of
empty PCIe slots in the server might also help to avoid the "PCI resource exhaustion"
event.

4.2.4 Removing and Installing PCIe Cards and PCIe
Card Filler Panels

Use the following procedures to remove and install PCIe cards and PCIe card filler
panels.

▼ Remove a PCIe Card Filler Panel
