What your server offers

The server uses the following features and technologies:

v UEFI-compliant server firmware

IBM UEFI firmware offers several features, including Unified Extensible Firmware Interface (UEFI) 2.1 compliance; Active Energy Manager technology; enhanced reliability, availability, and serviceability (RAS) capabilities; and basic input/output system (BIOS) compatibility support. UEFI replaces the BIOS and defines a standard interface between the operating system, platform firmware, and external devices. UEFI-compliant System x UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.

Note: The server does not support DOS. For more information about UEFI, go to http://www-947.ibm.com/systems/

support/supportsite.wss/docdisplay?lndocid=MIGR-5083207 &brandind=5000008.

v Integrated management module

The integrated management module (IMM) combines service processor functions, video controller, and remote presence and blue-screen capture features in a single chip. The IMM provides advanced service processor control, monitoring, and alerting function. If an environmental condition exceeds a

8 IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide

servers are capable of booting

threshold or if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in the IMM event log, and alerts you to the problem. Optionally, the IMM also provides a virtual presence capability for remote server management capabilities. The IMM provides remote server management through industry-standard interfaces:

– Intelligent Platform Management Interface (IPMI) version 2.0 – Simple Network Management Protocol (SNMP) version 3 – Common Information Model (CIM) – Web browser (For more information, see “Using the integrated management

module” on page 104.)

v IBM Systems Director

IBM Systems Director is a platform-management foundation that streamlines the way you manage physical and virtual systems in a heterogeneous environment. By using industry standards, IBM Systems Director supports multiple operating systems and virtualization technologies for IBM and non-IBM x86 platforms. For more information, see the documentation on the IBM Systems Director DVD and “IBM Systems Director” on page 12.

v IBM Electronic Service Agent

IBM Electronic Service Agent is a software tool that monitors the server for hardware error events and automatically submits electronic service requests to IBM service and support. Also, it can collect and transmit system configuration information on a scheduled basis so that the information is available to you and your support representative. It uses minimal system resources, is available free of charge, and can be downloaded from the web. For more information and to download Electronic Service Agent, go to http://www.ibm.com/support/ electronic/.

v IBM X-Architecture

technology

IBM X-Architecture technology combines proven, innovative IBM designs to make your x86-processor-based server powerful, scalable, and reliable. For more information, see http://www.ibm.com/servers/eserver/xseries/xarchitecture/ enterprise/index.html.

v Large system-memory capacity

The server supports up to 1 TB of system memory. The memory controller supports error correcting code (ECC) for up to 64 industry-standard PC3-10600, 240-pin, registered, double-data-rate (DDR) III, synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs). The optional 32-DIMM IBM MAX5 for System x memory expansion module is available for purchase and provides up to 512 GB of additional memory. For more information about the memory expansion module, see “IBM MAX5 for System x memory expansion module” on page 21.

v Memory ProteXion

The Memory ProteXion feature provides the equivalent of a hot-spare drive in a RAID array. It is based in the memory controller, and it enables the server to sense when a chip on a DIMM has failed and to route the data around the failed chip.

v Memory Sparing

The server supports memory sparing. Memory sparing reserves memory capacity for failover in the event of a DIMM failure, and the reserved capacity is subtracted from the total available memory. Memory sparing provides less redundancy than memory mirroring does. If a predetermined threshold of correctable errors is reached, the contents of the failing DIMM are copied to the spare memory, and the failing DIMM or rank is disabled. To enable memory

Chapter 1. The System x3850 X5 and x3950 X5 server 9

sparing through the Setup utility, select System Settings > Memory. (Memory sparing and memory mirroring cannot be used together.)

v IBM ServerGuide Setup and Installation CD

v Redundant connection

The addition of an optional network interface card (NIC) provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic that is associated with the primary connection is automatically switched to the redundant NIC. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.

v Redundant cooling and power capabilities

The redundant cooling of the fans in the server enables continued operation if one of the fans fails. The server supports up to two hot-swap power supplies, which provide redundant power for many server configurations.

v ServeRAID support

The server supports ServeRAID controllers to create a redundant array of independent disks (RAID) configurations.

v Symmetric multiprocessing (SMP)

The server supports up to four multi-core Intel Xeon microprocessors. One or more multi-core microprocessors provides SMP capability.

Reliability, availability, and serviceability

Three important server design features are reliability, availability, and serviceability (RAS). The RAS features help to ensure the integrity of the data that is stored in the server, the availability of the server when you need it, and the ease with which you can diagnose and correct problems.

The server has the following RAS features: v Advanced memory features:

– Single-bit memory error detection – Single-bit memory error hardware correction – Multi single-bit memory error recovery and corrections – Uncorrectable error (UE) detection – Full array memory mirroring (FAMM) redundancy – Automatic failover recovery for UEs when FAMM is configured – Automated logical removal of failed DIMMs on reboots prior to replacement – Automatic address parity checking during writes and reads

v Automatic BIOS recovery (ABR) for UEFI v Automatic error retry and recovery v Automatic restart after a power failure v Availability of microcode and diagnostic levels v Integrated management module (service processor) v Built-in, menu-driven electrically erasable programmable ROM (EEPROM) based

IBM Systems Director

Through a single user interface, IBM Systems Director provides consistent views for viewing managed systems, determining how these systems relate to one another, and identifying their statuses, helping to correlate technical resources with business needs. A set of common tasks that are included with IBM Systems Director provides many of the core capabilities that are required for basic management, which means instant out-of-the-box business value. These common tasks include discovery, inventory, configuration, system health, monitoring, updates, event notification, and automation for managed systems.

The IBM Systems Director Web and command-line interfaces provide a consistent interface that is focused on driving these common tasks and capabilities:

v Discovering, navigating, and visualizing systems on the network with the

detailed inventory and relationships to the other network resources

v Notifying users of problems that occur on systems and the ability to isolate the

sources of the problems

v Notifying users when systems need updates and distributing and installing

updates on a schedule

v Analyzing real-time data for systems and setting critical thresholds that notify

the administrator of emerging problems

12 IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide

Server power features

When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic except for the integrated management module (IMM) is shut down; however, the server can respond to requests from the IMM, such as a remote request to turn on the server. The power-on LED flashes to indicate that the server is connected to ac power but not turned on.

In a two-node configuration, connect both servers to an ac power source as close to the same time as possible to ensure optimum operation.

Turning on the server

Approximately 30 seconds, or up to 8 minutes in a 2-node configuration, after the server is connected to ac power, the power-control button becomes active, and one or more fans might start running to provide cooling while the server is connected to power. You can turn on the server and all nodes in the partition and start the operating system by pressing the power-control button.

If you are restarting a two-node server after it has been turned off, you must allow extra time for the hardware to synchronize before you turn on the server again.

The server can also be turned on in any of the following ways: v If a power failure occurs while the server is turned on, the server will restart

automatically when power is restored.

v The systems-management software can turn on the server remotely. v If your operating system supports the Wake on LAN feature, the Wake on LAN

feature can turn on the server.

Chapter 1. The System x3850 X5 and x3950 X5 server 19

If you purchased an optional IBM MAX5 for System x (MAX5) memory expansion module, it supports up to 32 DDR3 DIMMs, two 675-watt power supplies, and five 40 mm hot-swap speed-controlled fans. It provides added memory and multi-node scaling support for host servers. The MAX5 expansion module is based on eX5, the next generation of Enterprise X-Architecture. The MAX5 expansion module is designed for performance, expandability, and scalability; the fans and power supplies use hot-swap technology for easy replacement without requiring that expansion module be turned off.

Notes:

1. Before you attach the memory expansion module to the server and try to use it, you must update the server firmware with the latest level of firmware or code. The firmware in the server and the memory expansion module must be at the same level. If you attach and try to use the memory expansion module without updating the server firmware or making sure that the firmware in the server and memory expansion module are at the same level, you might get unexpected system behavior, or the server might not power on. For special instructions to follow before you attach the memory expansion module to the server, see http://www.ibm.com/support/entry/portal/ docdisplay?lndocid=MIGR-5085756.

2. When you add an optional memory expansion module to your server configuration and you plan to use the optional USB flash device with VMware ESXi embedded hypervisor software, see the documentation that comes with the USB flash device and the operating-system installation instructions for installing VMware ESXi (or ESX, depending on your environment) on your server at http://www.ibm.com/systems/support/. The documentation provides additional installation and configuration information that you must to follow before you use the memory expansion module.

What the memory expansion module offers

The memory expansion module provides several features for easy operation, including the following features:

v Replaceable components

The major replaceable components in the memory expansion module are dual inline memory modules (DIMMs), fans, and power supplies. See “Memory expansion module components” on page 81 for the components that the expansion module supports.

24 IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide

v Light path diagnostics LEDs

The memory expansion module has light path diagnostics LEDs (front and rear) to indicate hardware, scaling, and power problems.

v Redundant cooling and power capabilities

The memory expansion module supports a maximum of two 675-watt hot-swap power supplies and five single-motor hot-swap fans. The redundant fans provide continued cooling if one fan fails. The memory expansion module comes with one 675-watt hot-swap power supply and five fans. If a problem occurs with one of the power supplies, the other power supply can meet the power requirements.

v Large memory capacity

The memory bus supports up to 1 TB of memory. The memory controller supports error correcting code (ECC) for up to 32 industry-standard 1066 MHz PC3-10600R-999 or 1333 MHz PC3-8500, DDR3 (third-generation double-data-rate), registered, synchronous dynamic random access memory (SDRAM) DIMMs.

Reliability, availability, and serviceability features of the memory expansion module

Three of the most important features in product design are reliability, availability, and serviceability (RAS). These factors help to ensure that the integrity of the data processed in your memory expansion module is preserved, that the expansion module is available when you want to use it, and should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience.

The memory expansion module has a 1-year parts and 1-year labor limited warranty, or it assumes the warranty of the x3850 X5 or x3950 X5 host server to which it is attached, whichever is longer.

The following is an abbreviated list of the RAS features that the expansion module supports:

v Chipkill memory protection v Hot-swap and redundant cooling with fan-speed-sensing capability (front

serviceability)

v Hot-swap and redundant power supplies (rear serviceability) v Information LED panel v In-rack serviceability v Memory redundant bit steering (RBS) and error correcting code (ECC) v Memory mirroring support (mirrored DIMMs are mutually exclusive of each

other)

v QuickPath Interconnect (QPI) fail down v Rear serviceability power supplies

Chapter 1. The System x3850 X5 and x3950 X5 server 27

Turning on the memory expansion module

The memory expansion module is controlled by the server. Turning on the memory expansion module refers to connecting the memory expansion module power cord to the power source and pressing the power-control button on the host server. The host server must be connected to the memory expansion module and configured to identify the memory expansion module. Normally, when the operating system on the server starts, the server issues a power-on request to the memory expansion module.

Turning off the memory expansion module

The memory expansion module is turned off only if the connected server issues a power-off request and you disconnect the memory expansion module power cord from the power source. You cannot turn off the memory expansion module manually.

Statement 5

You can disconnect the memory expansion module power cords from the power source to shut off all power immediately without damaging the memory expansion module, but it might cause an unrecoverable error and loss of data on the connected server.

Chapter 2. Installing optional devices

This chapter provides detailed instructions for installing optional hardware devices in the server.

In addition to the instructions in this chapter for installing optional hardware devices, updating firmware and device drivers, and completing the installation, IBM Business Partners must also complete the steps in “Instructions for IBM Business Partners.”

Important: To help ensure that the devices that you install work correctly and do not introduce problems, observe the following precautions:

1. Make sure that the server and the installed firmware levels support the devices that you are installing. If necessary, update the UEFI and IMM firmware and any other firmware that is stored on the system boards. For information about where firmware is stored in the server, see Chapter 6, “Configuration information and instructions,” in the Problem Determination and Service Guide. For a list of supported optional devices for the server, see http:// www.ibm.com/systems/info/x86servers/serverproven/compat/us/.

2. Before you install optional hardware devices, make sure that the server is working correctly. Start the server and make sure that the operating system starts, if an operating system is installed, or that a 19990305 error code is displayed, indicating that an operating system was not found but the server is otherwise working correctly. If the server is not working correctly, see the Problem Determination and Service Guide for information about how to run diagnostics.

3. Follow the installation procedures in this chapter and use the correct tools. Incorrectly installed devices can cause system failures because of damaged pins in sockets or connectors, loose cabling, or loose components.

4. Use the best practices to apply current firmware and device-driver updates for the server and optional devices. To download the IBM System x Firmware Update Best Practices document, go to http://www.ibm.com/support/entry/portal/ docdisplay?brand=50000020&lndocid=MIGR-5082923.

Installation guidelines

Before you install optional devices, read the following information: v Read “Safety” on page v, “Working inside the server with the power on” on

page 40, and “Handling static-sensitive devices” on page 40. This information will help you work safely.

v Make sure that the devices that you are installing are supported. For a list of

supported optional devices for the server, see http://www.ibm.com/systems/ info/x86servers/serverproven/compat/us/.

v When you install your new server, take the opportunity to download and apply

the most recent firmware updates. This step will help to ensure that any known issues are addressed and that your server is ready to function at maximum levels of performance. To download firmware updates for your server, go to http://www.ibm.com/supportportal/.

Note: Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code.

For additional information about tools for updating, managing, and deploying firmware, see the ToolsCenter for System x and BladeCenter at http://publib.boulder.imm.com/infocenter/toolstr/v1r0/index.jsp.

In a two-node configuration, make sure that the UEFI firmware, FPGA, and IMM code are at the same levels on all nodes.

v Before you install optional hardware devices, make sure that the server is

working correctly. Start the server, and make sure that the operating system

38 IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide

starts, if an operating system is installed, or that a 19990305 error code is displayed, indicating that an operating system was not found but the server is otherwise working correctly. If the server is not working correctly, see the Problem Determination and Service Guide on the IBM Documentation CD for information about how to run diagnostics.

v Observe good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

v If you must start the server while the cover is removed, make sure that no one is

near the server and that no tools or other objects have been left inside the server.

v Do not attempt to lift an object that you think is too heavy for you. If you have

to lift a heavy object, observe the following precautions: – Make sure that you can stand safely without slipping. – Distribute the weight of the object equally between your feet. – Use a slow lifting force. Never move suddenly or twist when you lift a heavy

object.

– To avoid straining the muscles in your back, lift by standing or by pushing

up with your leg muscles.

v Make sure that you have an adequate number of properly grounded electrical

outlets for the server, monitor, and other devices.

v Back up all important data before you make changes to disk drives. v Have a small flat-blade screwdriver available. v To view the error LEDs on the system board and internal components, leave the

server connected to power.

v You do not have to turn off the server to install or replace hot-swap power

supplies, hot-swap hard disk drives, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices. However, you must turn off the server before you perform any steps that involve removing or installing adapter cables.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the server, open or close a latch, and so on.

v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that if the server and operating system support hot-swap capability, you can remove or install the component while the server is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

v When you are finished working on the server, reinstall all safety shields, guards,

labels, and ground wires.

A single-power-supply server operating at 208 V ac

One power supply operating at 208 V ac supports a fully populated server, but it does not support power or cooling redundancy.

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that the following requirements are met:

v Each of the drive bays has a drive or an electromagnetic compatibility (EMC)

shield installed in it.

Chapter 2. Installing optional devices 39

v If the server has redundant power, each of the power-supply bays has a power

supply installed in it.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the server. Do not place objects in front of the fans. For proper cooling and airflow, replace the top cover before you turn on the server. Operating the server for extended periods of time (more than 30 minutes) with the top cover removed might damage server components.

v You have followed the cabling instructions that come with optional adapters. v You have replaced a failed fan within 48 hours. v You have replaced a hot-swap drive within 2 minutes of removal. v For redundant and hot-swappable power supply operation, the power supplies

are connected to 200 - 240 V ac.

v Microprocessor sockets1-4each always contain either a heat-sink blank or a

microprocessor and heat sink.

Working inside the server with the power on

Attention: Static electricity that is released to internal server components when the server is powered on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.

The server supports hot-swap devices and is designed to operate safely while it is turned on and the cover is removed. Follow these guidelines when you work inside a server that is turned on:

v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved

shirts before you work inside the server; do not wear cuff links while you are working inside the server.

v Do not allow your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket, such as pens and pencils, that might fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,

into the server.

Handling static-sensitive devices

Attention: Static electricity can damage the server and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Wear an electrostatic-discharge wrist strap, if one is available. v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry.

40 IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide

v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted

metal surface on the outside of the server for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into the server

without setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on the server cover or on a metal surface.

v Take additional care when you handle devices during cold weather. Heating

reduces indoor humidity and increases static electricity.

Installing a hot-swap hard disk drive

The following notes describe the types of hard disk drives that the server supports and other information that you must consider when you install a hard disk drive:

v To confirm that the server supports the hard disk drive that you are installing,

see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.

v The server supports up to eight 1-inch (26 mm) slim-high, 2.5-inch, hot-swap

hard disk drives in the standard hot-swap bays.

v Start installing the hard disk drives from the bottom bay (bay 0). v If the server will be configured for RAID operation, see the documentation that

comes with the controller for instructions for installing a hard disk drive.

v All hot-swap drives in the server should have the same throughput speed rating;

using drives with different speed ratings might cause all drives to operate at the lowest throughput speed.

v To minimize the possibility of damage to the hard disk drives when you install

the server in a rack configuration, install the server in the rack before you install the hard disk drives.

v You do not have to turn off the server to install hot-swap drives in the hot-swap

drive bays. However, you must turn off the server when you perform any steps that involve installing or removing cables.

Chapter 2. Installing optional devices 53

Installing a microprocessor

The following notes describe the type of microprocessor that the server supports and other information that you must consider when you install a microprocessor:

v To confirm that the server supports the microprocessor that you are installing,

see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.

v The optional microprocessors that IBM supports are limited by the capacity and

capability of the server. Any microprocessors that you install must have the same specifications as the microprocessors that came with the server.

v The server supports up to four Intel Xeon microprocessors. If you are installing

two or more microprocessors, they must be the same cache size and type, and the same clock speed.

v Do not mix Intel Xeon versions of the 6000 and 7000 Series and the E7 Series

microprocessors in the same server, it is not supported. In addition:

Chapter 2. Installing optional devices 73

– Intel Xeon EX versions of the 6000 and 7000 Series microprocessors are

supported only on machine types 7145 and 7146.

– Intel Xeon EX E7 Series microprocessors are supported only on machine types

7143 and 7191.

v The server can operate as a symmetric multiprocessing (SMP) server. With SMP,

certain operating systems and application programs can distribute the processing load among the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

v Because of space limitations, you must use the microprocessor tool that comes

with the microprocessor, when you install the microprocessor.

v Read the documentation that comes with the microprocessor to determine

whether you have to update the UEFI firmware (server firmware). To download the most current level of UEFI firmware, go to http://www.ibm.com/systems/ support/.

v Obtain an SMP-capable operating system. For a list of supported operating

systems, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.

v You can use the Setup utility to determine the specific type of microprocessor in

the server.

v Microprocessor sockets must always contain either a heat-sink blank or a

microprocessor and heat sink.

v Populate the microprocessor sockets in the following order: 1, 4, 2, and 3. The

following illustration shows the locations of the microprocessor sockets on the microprocessor board.

Microprocessor 1

Microprocessor 2

Microprocessor 3

Microprocessor 4

Note: In a one node server only, if your server has more than two microprocessors installed, you must install two QPI wrap cards in the server.

To install a microprocessor, complete the following steps:

1. Read “Safety” on page v and “Installation guidelines” on page 38.

2. Turn off the server and peripheral devices, and disconnect the power cords

and all external cables as necessary to replace the device.

3. Remove the server top cover (see “Removing the top cover” on page 44).

optional devices. It might be easier for you to route any cables before you install certain optional devices.

The following illustration shows the locations of the input and output connectors on the rear of the server.

Chapter 2. Installing optional devices 79

Updating the server configuration

When you start the server for the first time after you add or remove a device, you might receive a message that the configuration has changed. The Setup utility starts automatically so that you can save the new configuration settings. For more information, see Chapter 3, “Configuring the server,” on page 95.

Some optional devices have device drivers that you must install. For information about installing device drivers, see the documentation that comes with each device.

Before you attach a memory expansion module to the server and try to use it, you must update the server firmware with the latest level of firmware or code. If you attach and try to use the memory expansion module without updating the server firmware, you might get unexpected system behaviour or the server might not power on. For special instructions to follow before you attach the memory expansion module to the server, go to http://www.ibm.com/support/entry/ portal/docdisplay?Indocid=MIGR-5085756.

The server comes with at least one microprocessor. If more than one microprocessor is installed, the server can operate as a symmetric multiprocessing (SMP) server. You might have to upgrade the operating system to support SMP. For more information, see “Typical operating-system installation” on page 104 and the operating-system documentation.

If the server has an optional RAID adapter and you have installed or removed a hard disk drive, see the documentation that comes with the RAID adapter for information about reconfiguring the disk arrays.

Installing DIMMs in the memory expansion module

The following notes describe the types of DIMMs that the memory expansion module supports and other information that you must consider when you install DIMMs.

v To confirm that the memory expansion module supports the DIMMs that you

are installing, see http://www.ibm.com/systems/info/x86servers/ serverproven/compat/us/.

v The memory expansion module supports a maximum of 32 DIMMs (single-rank,

dual-rank, or quad-rank).

Note: To determine the type of a DIMM, see the label on the DIMM. The information on the label is in the format xxxxx nRxxx PC3-xxxxx-xx-xx-xxx. The numeral in the sixth numerical position indicates whether the DIMM is single-rank (n=1) or dual-rank (n=2).

v The DIMM options that are available for the memory expansion module are 2

GB, 4 GB, 8 GB, 16 GB, and 32 GB.

v If you install 32 GB DIMMs in the memory expansion module, all of the DIMMs

must be 32 GB capacity DIMMs. You cannot mix 32 GB DIMMs with other capacity DIMMs in the memory expansion module.

v The memory expansion module supports a minimum of 4 GB and a maximum

of 1 TB of system memory.

v The memory expansion module supports 1.35 V (low-voltage) and 1.5 V DIMMs.

In addition, support is dependent on the host server machine type that the memory expansion module is connected to, as follows:

– When connecting the memory expansion module to Machine Types 7145 and

7146, install only 1.5 V DIMMs in the memory expansion module

– When connecting the memory expansion module to Machine Types 7143 and

7191:

- The memory expansion module supports low-voltage (1.35 V) DIMMs at capacities of 4 GB, 8 GB, 16 GB, and 32 GB only.

- If you install 32 GB DIMMs in the memory expansion module, all of the DIMMs must be 32 GB capacity DIMMs. You cannot mix the 32 GB DIMMs with other capacity DIMMs in the memory expansion module.

- When you mix 1.35 V and 1.5 V DIMMs in the memory expansion module, the memory expansion module operates at the 1.5 V rate.

- You can enable all DIMMs (1.35 V and 1.5 V) to operate at 1.5 V in the host server Setup utility.

v Some memory expansion modules come with the Intel 7500 scalable memory

buffer memory card or the Intel 7510 scalable memory buffer memory card. See the parts listing table for the memory expansion module in the Problem Determination and Service Guide for information about the Intel memory buffer memory card that is supported on the memory expansion module system-board tray.

Chapter 2. Installing optional devices 83

v Double-device data correction support is only available when 16 GB x4 DRAM

technology DIMMs are installed in the memory expansion module and the memory expansion module is connected to a host server.

v The memory expansion module supports memory sparing through the host

server. Memory sparing reserves memory capacity for failover in the event of a DIMM failure, and the reserved capacity is subtracted from the total available memory. Memory sparing provides less redundancy than memory mirroring does. If a predetermined threshold of correctable errors is reached, the contents of the failing DIMM are copied to the spare memory, and the failing DIMM or rank is disabled. To enable memory sparing through the Setup utility, select System Settings > Memory.

v When you populate DIMMs in the memory expansion module, populate the

larger capacity DIMMs first; then the smaller capacity DIMMs. See Table 12 on page 85 for non-mirroring mode DIMM population sequence and Table 13 on page 86 for memory-mirroring mode DIMM population sequence.

v The memory expansion module provides eight memory ports (memory

channels) and each memory port supports up to four DIMMs. Do not mix DIMMs with x4 technology (DIMMs with DRAMs that are organized with 4 data lanes) and x8 technology (DIMMs with DRAMs that are organized with 8 data lanes) in the same memory port.

are x8 technology DIMMs.

v Do not mix DIMMs with 1 Gb (gigabit) technology, 2 Gb DRAM technology, or

other gigabit DRAM technologies in banks of eight DIMMs on memory ports that are on the same memory controller. This is not supported in the memory expansion module. The following table lists the DIMM connectors for each bank of eight DIMMs that are on the memory ports within the same memory controller.

v DIMMs must be installed in pairs for non-mirroring mode and in sets of four for

memory-mirroring mode.

84 IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide

v A minimum of two DIMMs must be installed in the memory expansion module

for each microprocessor in the host server.

v The maximum operating speed of the memory expansion module is determined

by the slowest DIMM installed in the memory expansion module.

v The memory expansion module does not come with any DIMMs when you

purchase it as an optional device. When you install DIMMs, install them in the order shown in the following tables to optimize system performance.

v The memory expansion module supports non-mirroring mode and

memory-mirroring mode through the host server. – Non-mirroring mode. When you use the non-mirroring mode, install DIMMs

as indicated in the following table.

Note: When you populate DIMMs in the memory expansion module, populate the larger capacity DIMMs first, then the smaller capacity DIMMs.

– Memory-mirroring mode. When you use the mirroring mode feature,

consider the following information:

- Memory-mirroring mode replicates and stores data on sets of DIMMs simultaneously. If a failure occurs, the memory controller switches from the primary set of DIMMs to the backup set of DIMMs. To enable memory mirroring through the Setup utility, select System Settings → Memory. For more information, see “Using the Setup utility” on page 96.

- DIMMs must be installed in sets of four. The DIMMs in each set must be the same size and type. This is applicable also when the memory expansion module is attached to a host server and the host server has an optional memory tray installed in the server. You must install DIMMs in sets of four DIMMs for memory-mirroring mode in each (server, memory tray, and the memory expansion module).

Chapter 2. Installing optional devices 85

- The maximum available memory is reduced to half of the installed memory when memory mirroring is enabled. For example, if the memory expansion module has 64 GB of memory installed, only 32 GB of addressable memory is available when you use memory mirroring.

- The following table lists the DIMM installation sequence for memory-mirroring mode.
