What your server offers

The server uses the following features and technologies:

vActive PCI-X (hot-plug) adapter capabilities

The server has six hot-plug slots for peripheral component interconnect (PCI-X) adapters. With operating-system support, you can replace a failing hot-plug PCI-X adapter without turning off the server. If the operating system and adapter support the hot-add feature, you can also add a PCI adapter in one of these slots without turning off the server.

vBaseboard management controller

The baseboard management controller provides environmental monitoring for the server. If environmental conditions exceed thresholds or if system components fail, the baseboard management controller lights LEDs to help you diagnose the problem and records the errors in the error log. The baseboard management controller is also known as the service processor.

The baseboard management controller also provides remote server management capabilities through the OSA SMBridge management utility program.

vIBM Director

IBM Director is a workgroup-hardware-management tool that you can use to centrally manage IBM System x and xSeries servers. For more information, see the IBM Director documentation on the IBM Director CD.

vIBM Enterprise X-Architecture technology

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

ActiveMemory

The Active Memory feature improves the reliability of memory through memory mirroring, memory scrubbing, and the Memory ProteXionfeature.

Large system-memory capacity

The server supports up to 64 GB of system memory. The memory controller supports error correcting code (ECC) for up to 16 industry-standard PC2-3200, 333 megahertz (MHz), 1.8 V, 240-pin, registered, double-data-rate (DDR) II, synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs).

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.

vIBM ServerGuideSetup and Installation CD

The ServerGuide Setup and Installation CD that comes with the server (standard on some models only) provides programs to help you set up the server and install a 32-bit Windows operating system. The ServerGuide program detects installed hardware options and provides the correct configuration programs and device drivers. For more information about the ServerGuide Setup and Installation CD, see “Using the ServerGuide Setup and Installation CD” on page 63.

Chapter 1. The System x3950 and System x3950 E server 5

vIntegrated network support

The server comes with an integrated Broadcom 5704C dual Gigabit Ethernet controller, which supports connection to a 10-Mbps, 100-Mbps, or 1000-Mbps network. For more information, see “Configuring the Gigabit Ethernet controller” on page 66.

vLarge data-storage capacity and hot-swap capability

The server supports up to six 25.4-mm (1-inch) slim-high, 2.5-inch hot-swap hard disk drives that are connected to the SAS backplane. With the hot-swap feature, you can add, remove, or replace hard disk drives without turning off the server.

vLight path diagnostics

Light path diagnostics provides LEDs to help you diagnose problems. For more information, see the section about light path diagnostics in the Installation Guide.

vPowerExecutive

PowerExecutive is an IBM Director extension that measures and reports server power consumption as it occurs. This enables you to monitor power consumption in correlation to specific software application programs and hardware configurations. You can obtain the measurement values through the systems-management interface, and can view them using IBM Director. For more information, including the required levels of IBM Director and PowerExecutive, see the IBM Director documentation on the IBM Director CD, or go to http://www.ibm.com/servers/eserver/xseries/systems_management/ibm_director /extensions.

vRedundant 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.

vRedundant cooling and power capabilities

The redundant cooling of the fans in the server enable 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.

vScalable partitions

The server is scalable and can be connected to multiple servers so that you can share resources between servers.

vServeRAIDsupport

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

vSymmetric multiprocessing (SMP)

The server supports up to four Intel Xeon microprocessors. If the server comes with only one microprocessor, you can install additional microprocessors to enhance performance and provide SMP capability.

vSystems-management capabilities

The server supports the IBM Remote Supervisor Adapter II SlimLine. When this adapter is used with the systems-management software that comes with the server, you can manage the functions of the server locally and remotely. The Remote Supervisor Adapter II SlimLine also provides system monitoring, event recording, and dial-out alert capability.

Installation guidelines

Before you install options, read the following information:

vRead the safety information that begins on page v, the guidelines in “Working inside the server with the power on” on page 22, and “Handling static-sensitive devices” on page 23. This information will help you work safely.

vWhen 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/servers/eserver/support/xseries/index.html, select System x3950 or System x3950 E from the Hardware list, click Go, and then click the Download tab. For additional information about tools for updating, managing, and deploying firmware, see the System x and xSeries Tools Center at http://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.

vBefore 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 “Solving Problems” in the Installation Guide for diagnostic information.

vObserve good housekeeping in the area where you are working. Place removed covers and other parts in a safe place.

vIf 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.

vDo 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.

vMake sure that you have an adequate number of properly grounded electrical outlets for the server, monitor, and other devices.

vBack up all important data before you make changes to disk drives.

vHave a small flat-blade screwdriver available.

vYou do not have to turn off the server to install or replace hot-swap power supplies, hot-swap fans, hot-plug adapters, 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.

vBlue 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.

vOrange 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.

Chapter 2. Installing options 21

vWhen you are finished working on the server, reinstall all safety shields, guards, labels, and ground wires.

vFor a list of supported optional devices for the server, see http://www.ibm.com/ servers/eserver/serverproven/compat/us/.

System reliability guidelines

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

vEach of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed in it.

vThere is adequate space around the server to allow the server cooling system to work properly. Leave approximately 50 mm (2 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 server cover before turning on the server. Operating the server for extended periods of time (more than 30 minutes) with the server cover removed might damage server components.

vIf the server has redundant power, each of the power-supply bays has a power supply installed in it.

vYou have followed the cabling instructions that come with optional adapters.

vYou have replaced a failed fan as soon as possible.

vYou have replaced a hot-swap drive within 2 minutes of removal.

vYou do not run the server without the air baffle installed. Operating the server without the air baffle might cause the microprocessor or microprocessors to overheat.

vMicroprocessor sockets 2, 3, and 4 each always contain either a microprocessor baffle or a microprocessor and heat sink.

vFor redundant and hot-swappable operation, the power supplies are connected to 200-240 V ac.

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 could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

The server supports hot-plug, hot-add, and 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:

vAvoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the server; do not wear cuff links while you are working inside the server.

vDo not allow your necktie or scarf to hang inside the server.

vRemove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist watches.

vRemove items from your shirt pocket, such as pens and pencils, that could fall into the server as you lean over it.

vAvoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.

22 IBM System x3950 Type 8878 and System x3950 E Type 8879: User’s Guide

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:

vLimit your movement. Movement can cause static electricity to build up around you.

vThe use of a grounding system is recommended. For example, wear an electrostatic-discharge wrist strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on.

vHandle the device carefully, holding it by its edges or its frame.

vDo not touch solder joints, pins, or exposed circuitry.

vDo not leave the device where others can handle and damage it.

vWhile the device is still in its static-protective package, touch it to an unpainted metal part on the outside of the server for at least 2 seconds. This drains static electricity from the package and from your body.

vRemove 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.

vTake additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity.

Removing the cover and bezel

To remove the cover and bezel, complete the following steps:

1.Read the safety information that begins on page v and “Installation guidelines” on page 21.

2.If you are installing or replacing a non-hot-swap component, turn off the server and all attached peripheral devices. Disconnect all power cords; then, disconnect all external signal cables from the server.

3.Slide the server out of the rack until the slide rails lock into place.

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 installing a hard disk drive:

vThe server supports up to six 1-inch (26 mm) slim-high, 2.5-inch, hot-swap hard disk drives in the standard hot-swap bays.

vFor a list of supported options for the server, see http://www.ibm.com/servers/ eserver/serverproven/compat/us/.

vInspect the drive tray for signs of damage.

vMake sure that the drive is correctly installed in the tray.

vIf a RAID controller is installed in the server, see the documentation that comes with the controller for instructions for installing a hard disk drive.

vAll hot-swap drives in the server should have the same throughput speed rating; mixing speed ratings might cause all drives to operate at the lower throughput speed.

vTo minimize the possibility of damage to the hard disk drives when you are installing the server in a rack configuration, install the server in the rack before installing the hard disk drives.

vYou 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 performing any steps that involve installing or removing cables.

vSome filler panels come with a slim filler.

Memory module

The following notes describe the types of dual inline memory modules (DIMMs) that the server supports and other information that you must consider when installing DIMMs:

vThe server supports 333 MHz, 1.8V, 240 pin, PC2-3200 single-ranked double data-rate (DDR) II, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest PC2-3200 SDRAM Registered DIMM specifications. For a list of the supported options for the server, see http://www.ibm.com/servers/ eserver/serverproven/compat/us/.

vThe server supports up to four memory cards. Each memory card holds up to four DIMMs.

vThere must be at least one memory card with one pair of DIMMs installed for the server to operate.

vWhen you install additional DIMMs on a memory card, be sure to install them in pairs. All the DIMM pairs on each memory card must be the same size, and type.

vYou do not have to save new configuration information to the BIOS when installing or removing DIMMs. The only exception is if you replace a DIMM that was marked as Disabled in the Memory Settings menu. In this case, you must re-enable the row in the Configuration/Setup Utility program or reload the default memory settings.

vWhen you restart the server after adding or removing a DIMM, the server displays a message that the memory configuration has changed.

vInstall the DIMMs on each memory card in the order shown in the following tables, depending on which memory configuration you want to use. You must install at least one pair of DIMMs on each memory card.

vThere are two memory power buses split between the four memory cards. Memory cards 1 and 2 are on power bus 1, and memory cards 3 and 4 are on power bus 2. If memory mirroring is enabled, you can hot-replace one memory card at a time on each memory power bus.

vIf a problem with a DIMM is detected, light path diagnostics will light the system-error LED on the front of the server, indicating that there is a problem and guide you to the defective DIMM. When this occurs, first identify the defective DIMM; then, remove and replace the DIMM.

The following illustration shows the LEDs on the memory card:

Memory Port Power

Error

Memory Hot-Swap Enabled

Memory Hot-Swap Enabled LED: When this LED is lit, it indicates that hot-swap memory is enabled.

Error LED: When this LED is lit, it indicates that a memory card or DIMM has failed.

Memory Port Power LED: When this LED is off, it indicates that power is removed from the port and that you can remove the memory card and replace a failed DIMM. This LED will also turn off when the release levers are opened.

Note: Add odd numbered DIMMs to each available memory card first, then add the even numbered pairs.

Active Memory

Active Memory is an IBM technology that improves the reliability of the DIMMs through the memory mirroring, memory scrubbing, and Memory ProteXionfeatures.

Chapter 2. Installing options 33

The following notes describe the Active Memory features:

vMemory mirroring enables you to improve the reliability of the memory in your server by creating a mirror of the data in memory port 1 and storing it in memory port 2.

Note: For memory mirroring to work, you must have DIMMs of the same size and clock speed in both memory ports.

Complete the following steps to enable memory mirroring:

1.Check your operating system documentation to make sure that it supports memory mirroring.

2.Install DIMMs of the same size and clock speed in the two memory ports.

3.Enable memory mirroring in the Configuration/Setup Utility program:

a.Turn on the server and watch the monitor screen.

b.When the message Press F1 for Configuration/Setup appears, press F1.

c.From the Configuration/Setup Utility main menu, select Advanced Setup.

d.Select Memory Settings.

e.Select Memory Mirroring Settings.

f.Enable the memory mirroring setting from within this window.

g.Save and exit the Configuration/Setup Utility program.

When memory mirroring is enabled, the data that is written to memory is stored in two locations. One copy is kept in the memory port 1 DIMMs, while a second copy is kept in the memory port 2 DIMMs. During the execution of the read command, the data is read from the DIMM with the least number of reported memory errors through memory scrubbing, which is enabled with memory mirroring.

If memory scrubbing determines that a DIMM is damaged beyond use, read and write operations are redirected to the remaining good DIMMs. Memory scrubbing then reports the damaged DIMM and light path diagnostics displays the error.

After the damaged DIMM is replaced, memory mirroring then copies the mirrored data back into the new DIMM.

vMemory scrubbing is an automatic daily test of all the system memory that detects and reports memory errors that might be developing before they cause a server outage.

Note: Memory scrubbing and Memory ProteXion technology work with each other and do not require memory mirroring to be enabled to work.

When an error is detected, memory scrubbing determines whether the error is recoverable. If it is recoverable, Memory ProteXion is enabled and the data that was stored in the damaged locations is rewritten to a new location. The error is then reported so that preventive maintenance can be performed. Provided that there are enough good locations to enable the correct operation of the server, no further action is taken other than recording the error in the error logs.

If the error is not recoverable, memory scrubbing sends an error message to light path diagnostics, which lights LEDs to guide you to the damaged DIMM. If memory mirroring is enabled, the mirrored copy of the data in the mirrored DIMM is used to refresh the new DIMM after it is installed.

vMemory ProteXion reassigns memory bits to new locations within memory when recoverable errors have been detected.

34 IBM System x3950 Type 8878 and System x3950 E Type 8879: User’s Guide

When a recoverable error is found by memory scrubbing, the Memory ProteXion feature writes the data that was to be stored in the damaged memory locations to spare memory locations within the same DIMM.

Microprocessor

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

vFor a list of supported options for the server, see http://www.ibm.com/servers/ eserver/serverproven/compat/us/.

vThe 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.

vWith more than one microprocessor, 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.

vThe voltage regulators for microprocessors 1 and 2 are integrated on the microprocessor board; the VRMs for microprocessors 3 and 4 come with the microprocessor options and must be installed on the microprocessor board.

42 IBM System x3950 Type 8878 and System x3950 E Type 8879: User’s Guide

vRead the documentation that comes with the microprocessor to determine whether you must update the basic input/output system (BIOS) code in the server. To download the most current level of BIOS code for your server, see http://www.ibm.com/servers/eserver/support/xseries/index.html.

vObtain an SMP-capable operating system. For a list of supported operating systems, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.

vYou can use the Configurations/Setup utility program to determine the specific type of microprocessor in the server.

Microprocessor installation order

The following notes describe the order in which to populate the microprocessor connectors:

vFor most configurations, populate the microprocessor connectors in numeric order, starting with connector 1.

vIf you plan to create a two-node configuration using four dual-core microprocessors, you can populate the microprocessor connectors to improve performance. The following notes describe information that you must consider when configuring the servers to use the configuration:

You must create this configuration using one System x3950 (xSeries 460) server as the primary node and one System x3950 E (xSeries 460 MXE) server as the secondary node.

Only the configuration described in these instructions is supported to improve performance.

See this section for instructions on installing a microprocessor.

See the Problem Determination and Service Guide for instructions on removing a microprocessor.

Use this configuration only with supported Windows 2003 operating systems.

To configure a two-node configuration to use the four dual-core microprocessor configuration, complete the following steps.

Important: The grease on the heat sink and microprocessor will remain effective when you move a microprocessor from one connector to another connector, if you observe the following precautions:

vCarefully handle the heat sink and microprocessor when removing or installing these components. Do not touch the grease or otherwise allow it to become contaminated.

vBecause the microprocessor and heat sink are a matched set, transfer the microprocessor and heat sink from one connector to another connector one microprocessor and heat sink at a time. (This will ensure that the grease remains evenly distributed between each heat sink and microprocessor.)

Configuring the Gigabit Ethernet controller

The Ethernet controller is integrated on the I/O board. It provides an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in the server support auto-negotiation, the controller detects the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operates at that rate and mode.

You do not have to set any jumpers or configure the controller. However, you must install a device driver to enable the operating system to address the controller. Install the device drivers from the Broadcom NetXtreme Gigabit Ethernet Software

CD that comes with the server. For information about configuring the Ethernet controller, see the Broadcom NetXtreme Gigabit Ethernet Software CD. For updated information about configuring the controller, see http://www.ibm.com/servers/eserver/ support/xseries/index.html.

Using the Scalable Partition Web Interface

The Scalable Partition Web Interface is an extension of the Remote Supervisor Adapter II SlimLine Web Interface and is used to create, delete, control, and view scalable partitions. The Scalable Partition Web Interface is in the Remote Supervisor Adapter II SlimLine integrated service processor.

The scalable partition defines a multi-node configuration, which interconnects two, four, or eight servers. The multi-node configuration provides the function to individually power-on and power-off each node. The multi-node configuration uses a single, contiguous memory space and provides access to all associated adapters. Each scalable system can have one or more scalable partitions.

Before you create or delete scalable partitions, read the following information:

vA Remote Supervisor Adapter II SlimLine must be installed in all nodes that are to become part of a scalable partition.

vAll of the service processors must be connected to an Ethernet network through the SP connector on the rear of the node. This connection is needed so that the service processors can communicate with and manage scalable partitions.

vMake sure that all nodes in the multi-node configuration have the current level of BIOS code, SAS BIOS code, service processor firmware, BMC firmware, and CPLD firmware. The code and firmware levels must be the same for all nodes.

vWhen you set up the nodes for scalable partitions for the first time, you must first log on and configure the service processor in each node.

vPCI slot numbering starts with the primary node and continues with the secondary nodes, in numeric order of the logical node IDs.

Creating a scalable partition

To create a scalable partition, complete the following steps:

1.Make sure that the service processor on each node is configured and connected to the network. See the Remote Supervisor Adapter II SlimLine and Remote Supervisor Adapter II User’s Guide for more information.

Chapter 3. Configuring the server 81

2.Make sure that all nodes in the multi-node configuration contain microprocessors that are the same cache size and type, and the same clock speed.

3.Connect the SMP Expansion cables. See “SMP Expansion cabling” on page 49 for instructions.

4.Connect all nodes to an ac power source and make sure that they are not running an operating system.

5.Access the network used by the multi-node configuration and connect and log in to the Remote Supervisor Adapter II Web Interface on the primary node. See the Remote Supervisor Adapter II SlimLine and Remote Supervisor Adapter II User’s Guide for more information; then, continue with the procedure to create a scalable partition.

Note: The Remote Supervisor Adapter II Web Interface must be open to view, create, delete, or manage scalable partitions. Make sure that the Web Interface is open before you continue.
