v Light path diagnostics

Light path diagnostics provides LEDs to help you diagnose problems. For more information about light path diagnostics and the LEDs, see “Light path diagnostics” on page 18 and “Light path diagnostics LEDs” on page 159.

v Memory mirroring

Memory mirroring provides a redundant copy of all code and data that are addressable in the configured memory map. Through the microprocessor memory controller chip set, memory mirroring replicates and stores data across DIMMs on two or four memory channels simultaneously. If a failure occurs, the memory controller switches from the DIMMs on the primary channel to the DIMMs on the backup channel. To enable memory mirroring through the Setup utility, select System Settings → Memory → Memory Mode → Mirroring. For information about installing DIMMs for memory mirroring, see “Memory mirroring” on page 44 and “Installing a memory module” on page 41 for more information.

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 sparing through the Setup utility, select System Settings → Memory → Memory Mode → Sparing. For information about installing DIMMs for memory sparing, see “Memory sparing” on page 45.

v Multi-core processors

™

The server supports up to four Intel Xeon

EP 4S E5-4600 series, four-core, six-core, and eight-core microprocessors (depending on your model). The server comes with a minimum of one microprocessor.

Note: To install the third and fourth microprocessors, you must purchase and install an optional microprocessor and memory expansion tray. Both of the microprocessors must be installed as a pair on the microprocessor and memory expansion tray.

v PCI Express Gen3 adapter capabilities

The server provides up to eight PCIe Gen3 adapter slots. The system board provides five low-profile PCIe Gen3 adapter slots and the optional PCI riser-card provides three x8 (x16 mechanical) PCIe Gen3 adapter slots. See “Installing an adapter” on page 66 for detailed information.

Note: The second microprocessor must be installed on the system board for the server to support more than three PCIe slots on the system board or the optional PCI riser card.

v Redundant connection

The integrated Emulex BE3 dual-port Ethernet controller provides failover capability to a redundant Ethernet connection with the applicable application installed. If a problem occurs with the primary Ethernet connection and an

Chapter 1. The System x3750 M4 Types 8722 and 8733 server 11

optional Ethernet adapter is installed in the server, all Ethernet traffic that is associated with the primary connection is automatically switched to an optional Ethernet connection. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.

v Redundant cooling and optional power capabilities

The server comes with six dual-motor, counter-rotating, speed-controlled hot-swap fans, which provide redundancy and hot-swap capability for a full configuration. The redundant cooling by the fans in the server enables continued operation if one of the fan motors fails.

The server comes with one 900-watt or one 1400-watt hot-swap power supply. The server supports a maximum of two 900-watt or two 1400-watt hot-swap power supplies. For redundancy support, two power supplies must be installed in the server. Two power supplies enables continued operation if one of the power supplies fails. You can order the optional IBM Power Interposer for Redundant Power Option Kit or the optional IBM Microprocessor and Memory Expansion Tray to install a second power supply.

v Remote presence and blue-screen capture features

The remote presence and blue-screen capture features are integrated functions of the integrated management module (IMM). The remote presence feature provides the following functions:

– Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz,

regardless of the system state

– Remotely accessing the server, using the keyboard and mouse from a remote

client

– Mapping the CD or DVD drive, diskette drive, and USB flash drive on a

remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server

– Uploading a diskette image to the IMM memory and mapping it to the server

as a virtual drive

The blue-screen capture feature captures the video display contents before the IMM restarts the server when the IMM detects an operating-system hang condition. A system administrator can use the blue-screen capture feature to assist in determining the cause of the hang condition.

See “Using the remote presence and blue-screen capture features” on page 136 for additional information.

v ServeRAID support

A ServeRAID adapter provides hardware redundant array of independent disks (RAID) support to create configurations. The server comes with an integrated RAID controller, which provides RAID levels 0, 1 and 10. Additional optional RAID adapters, RAID cache cards, and Features on Demand software RAID are available for RAID levels 5, 6, 50, and 60 upgrade.

v Systems-management capabilities

The server comes with an integrated management module II (IMM2). When the IMM is used with the systems-management software that comes with the server, you can manage the functions of the server locally and remotely. The IMM also provides system monitoring, event recording, and network alert capability. The systems-management connector on the rear of the server is dedicated to the IMM. The dedicated systems-management connector provides additional security by physically separating the management network traffic from the production network. You can use the Setup utility to configure the server to use a dedicated systems-management network or a shared network.

v TCP/IP offload engine (TOE) support

12 System x3750 M4 Types 8722 and 8733: Installation and Service Guide

The Ethernet controllers in the server support TOE, which is a technology that offloads the TCP/IP flow from the microprocessor and I/O subsystem to increase the speed of the TCP/IP flow. When an operating system that supports TOE is running on the server and TOE is enabled, the server supports TOE operation. See the operating-system documentation for information about enabling TOE.

Note: As of the date of this document, the Linux operating system does not support TOE.

v UEFI-compliant server firmware

The UEFI firmware offers several features, including Unified Extensible Firmware Interface (UEFI) version 2.1 compliance, Active Energy Management (AEM) 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. The server is capable of booting UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters as well as UEFI-compliant adapters. For more information about UEFI-compliant firmware, go to http://www.ibm.com/systems/support/ supportsite.wss/docdisplay?lndocid=MIGR-5083207&brandind=5000008.

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 in IBM and non-IBM x86 platforms.

Through a single user interface, IBM Systems Director provides consistent views for viewing managed systems, determining how these systems relate to one other, 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. The common tasks include discovery, inventory, configuration, system health, monitoring, updates, event notification, automation for managed systems, hardware log, power, and light path.

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

source of the problem

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

v Configuring settings of a single system and creating a configuration plan that

can apply those settings to multiple systems

v Updating installed plug-ins to add new features and functions to the base

capabilities

v Managing the life cycles of virtual resources

Server power features

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

Turning on the server

Approximately 5 seconds after the server is connected to input power, one or more fans might start running and the power-on LED flashes quickly. Approximately 10 seconds after the server is connected to input power, the power-on button becomes active. After the power-on button becomes active, the power-on LED flashes slowly. You can turn on the server by pressing the power-on button.

If a power failure occurs while the server is turned on, the server will restart automatically when power is restored.

Note: To disable this feature in the Setup utility (see “Using the Setup utility” on page 127), select System Settings → Integrated Management Module → Power Restore Policy.

Turning off the server

When you turn off the server and leave it connected to input power, the server can respond to requests to the service processor (the integrated management module), such as a remote request to turn on the server. While the server remains connected to input power, one or more fans might continue to run. To remove all power from the server, you must disconnect it from the power source.

Some operating systems require an orderly shutdown before you turn off the server. See your operating-system documentation for information about shutting down the operating system.

Statement 5

CAUTION: The power control button on the device do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

Chapter 2. Installing optional devices 33

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/support/fixcentral/.

Important: 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.ibm.com/infocenter/toolsctr/v1r0/index.jsp.

v Before you install optional hardware, 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 “Running the DSA Preboot diagnostic programs” on page 171 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 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 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 and you must disconnect the power source from the server before you perform any steps that involve removing or installing a riser card.

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

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

v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed in it.

v Each of the power-supply bays has a power supply or a filler 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 server cover before you turn on the server.

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 fan within 30 seconds of removal. v You have replaced a hot-swap drive within 2 minutes of removal. v You have replaced a failed hot-swap power supply within 2 minutes of removal. v You do not operate the server without the air baffles installed. Operating the

server without the air baffles might cause the device to overheat.

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 Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. 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 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 you install DIMMs (see “System-board optional-device connectors” on page 31 for the location of the DIMM connectors):

v Confirm that the server supports the DIMM that you are installing (see

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

v When you install or remove DIMMs, the server configuration information

changes. When you restart the server, the system displays a message that indicates that the memory configuration has changed. You can use the Setup utility to view the server configuration information, see “Using the Setup utility” on page 127 for more information.

v The server supports only industry-standard double-data-rate 3 (DDR3),

PC3-12800R 1600 MHz, PC3L-10600R-999 1333 MHz or PC3L-10600 1333 MHz Load Reduced (LR), single-rank, dual-rank, or quad-rank, registered, synchronous dynamic random-access memory (SDRAM) dual inline memory modules (DIMMs) with error correcting code (ECC).

– The specifications of a DDR3 DIMM are on a label on the DIMM, in the

following format. gGB eRxf-PC3-wwwwwm-a-b-c-d where:

- gGB is the total capacity of the DIMM (for example, 1GB, 2GB, or 4GB)

- eR is the number of ranks 1R = single-rank 2R = dual-rank 4R = quad-rank

-xf is the device organization or bit width (for example, x4, x8, or x16) 4 = x4 organization (4 DQ lines per SDRAM) 8 = x8 organization 16 = x16 organization

- wwwww is the DIMM bandwidth, in MBps 6400 = 6.40 GBps (PC3-800 SDRAMs, 8-byte primary data bus) 8500 = 8.53 GBps (PC3-1066 SDRAMs, 8-byte primary data bus) 10600 = 10.66 GBps (PC3-1333 SDRAMs, 8-byte primary data bus) 12800 = 12.80 GBps PC3-1600 SDRAMs, 8-byte primary data bus)

- m is the DIMM type E = Unbuffered DIMM (UDIMM) with ECC (x72-bit module data bus) R = Registered DIMM (RDIMM) U = Unbuffered DIMM with no ECC (x64-bit primary data bus)

- a is the CAS latency, in clocks at maximum operating frequency

- b is the JEDEC SPD Revision Encoding and Additions level

- c is the reference design file for the design of the DIMM

- d is the revision number of the reference design of the DIMM

v The server supports 1.35-volt (low-voltage) registered DIMMs and 1.5-volt

(standard voltage) registered DIMMs as follows: – Supported DIMMs with speeds of 1333 MHz or less support both 1.35 V and

1.5 V operation, depending on the configuration settings in the Setup utility.

Chapter 2. Installing optional devices 41

– Supported DIMMs with speeds of 1600 MHz do not support 1.35 V operation.

Only 1.5 V operation is supported.

v Single-device data correction (SDDC) support is available only when 16 GB or 32

GB x4 DRAM technology DIMMs are installed in the server.

v The following table provides information about the maximum amount of

memory that the server can support when you fully populate the server and the optional microprocessor and memory expansion tray by using the supported DIMMs.

Table 5. The maximum amount of memory that the server can support

Number of DIMM connectors Maximum memory

24 DIMMs on system board Up to 768 GB 24 DIMMs on the optional microprocessor

and memory expansion tray

Note: The server can support a maximum 1.5 TB of system memory when the server is fully populated with 32 GB DIMMs and the optional microprocessor and memory expansion tray is installed and fully populated with 32 GB DIMMs.

Up to 768 GB

Total = 1.5 TB of memory

v The DIMM options that are available for the server are 4 GB, 8 GB, 16 GB, 32

GB.

v The server system board supports a minimum of 4 GB and a maximum of 768

GB of system memory. However, the server can support an additional 768 GB of memory when an optional microprocessor and memory expansion tray is installed in the server, for a total of 1.5 TB of system memory, depending on the model.

Note: The amount of usable memory is reduced, depending on the system configuration. A certain amount of memory must be reserved for system resources. To view the total amount of installed memory and the amount of configured memory, run the Setup utility. For additional information, see “Configuring the server” on page 124.

v The server system board provides four memory channels for each

microprocessor, and each memory channel supports up to three DIMMs. The optional microprocessor and memory expansion tray also provides four memory channels that support up to three DIMMs per channel. The following illustration shows the memory channels for each microprocessor.

The following table lists the DIMM connectors on each memory channel for the microprocessors on the system board and the optional expansion tray.

v When you replace a DIMM, the server provides automatic DIMM enablement

capability without requiring you to use the Setup utility to enable the new DIMM manually.

v The maximum operating speed of the server is determined by the slowest

DIMM in the server.

v DIMMs do not have to be installed in pairs, except in memory-mirroring mode. v A minimum of one DIMM must be installed for each microprocessor. For

example, you must install a minimum of two DIMMs if the server has two microprocessors (one for each microprocessor). If you install four microprocessors in the server, you must install a minimum of four DIMMs (one DIMM for each microprocessor). For more information about DIMM population sequence, see Table 8 on page 44, Table 9 on page 45, and Table 10 on page 46.

Note:

– When one DIMM per microprocessor is installed, system performance can be

slow.

– To run VMware, one DIMM per microprocessor must be installed. If a DIMM

is not installed for each microprocessor, the server will not be able to boot VMware.

– For best performance, install DIMMs evenly across all four memory channels

for each microprocessor.

v The server supports non-mirroring mode, memory mirroring mode, and memory

sparing mode. For more information and DIMM population for non-mirroring

mode, see “Non-mirroring (independent mode).” For more information and DIMM population for memory mirroring, see “Memory mirroring.” For more information and DIMM population for memory sparing, see “Memory sparing” on page 45.

Non-mirroring (independent mode)

When you use non-mirroring mode, follow the DIMM population sequence as indicated in the following table..

Note: When you install an optional microprocessor and memory expansion tray in the server, microprocessors 3 and 4 must be installed as a pair. The server does not support a configuration of three microprocessors.

Memory mirroring

Memory-mirroring replicates and stores data on DIMMs across two or four channels simultaneously. If a failure occurs, the memory controller switches from the DIMMs on the primary channel to the DIMMs on the backup channel. To enable memory mirroring through the Setup utility, select System Settings → Memory → Memory Mode. For more information, see “Using the Setup utility” on page 127.

When you use memory mirroring mode, consider the following information: v The server supports single-socket memory mirroring. Memory channel 0 mirrors

channel 1, and memory channel 2 mirrors channel 3. This mirroring provides redundancy in memory but reduces the total memory capacity in half.

v DIMMs must be installed in pairs for each microprocessor when using the

memory mirroring feature.

v The DIMM population must be identical for memory channel 0 and memory

channel 1, and identical for memory channel 2 and memory channel 3.

v Memory mirroring reduces the maximum available memory by half of the

installed memory. For example, if the server has 64 GB of installed memory, only 32 GB of addressable memory is available when memory mirroring is enabled.

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

mode.

Note: The server does not support a configuration of three microprocessors. The server supports one, two, or four microprocessors only.

Memory sparing

When you use memory sparing mode, consider the following information: v When single-rank or dual-rank DIMMs are used, at least three DIMMs must be

installed to support memory sparing.

v Each memory channel supports three DIMMs. The third DIMM in each channel

is the sparing DIMM for all of the DIMMs in the channel.

v When quad-rank DIMMs are used, one of the ranks in the DIMM itself is used

for sparing.

v The server supports one optional ultra-slim SATA CD-RW/DVD-ROM optical

drive.

v The server can support up to sixteen 2.5-inch drives, up to thirty-two 1.8-inch

drives, or a combination of both 2.5-inch and 1.8-inch hot-swap drives, using the supported SAS/SATA backplane configurations. The server supports 2.5-inch hot-swap SAS or hot-swap SATA hard disk drives, 2.5-inch hot-swap SATA solid state drives, and 1.8-inch hot-swap SATA solid state drives (see “Supported SAS/SATA drive backplane configurations” on page 53 for more information).

v You can mix 2.5-inch hot-swap SAS and SATA hard disk drives, 2.5-inch

hot-swap SATA solid-state drives, and 1.8-inch hot-swap SATA solid-state drives in the same server as long as you use the same type of drives within the same array.

v When you upgrading drive backplane configurations, you must install all

1.8-inch solid state drive backplanes to the right of all 2.5-inch hard disk drive or

2.5-inch solid state drive backplanes. All 2.5-inch backplanes must be installed to the left of all 1.8-inch backplanes. See “Drive IDs” for drive ID assignment information and “Supported SAS/SATA drive backplane configurations” on page 53 for information about the combination of supported drive backplane configurations.

v The 8x2.5-inch hot-swap drive backplane with controller expander must always

be installed in backplane bays 3 and 4. See “Connecting the SAS cables” on page 61 for more information about cabling the SAS cables.

v The electromagnetic interference (EMI) integrity and cooling of the server are

protected by having all bays and PCIe slots covered or occupied. When you install a drive, save the EMC shield and filler panel from the bay in the event that you later remove the device.

Drive IDs

The hot-swap-drive ID that is assigned to each drive is printed on the front of the server. The following illustrations show the locations of the IDs of the drives. The ID numbers and the drive bay numbers are the same.

Note:

1. The drive bay IDs can vary, depending on the combination of the SAS/SATA backplanes installed in the server.

2. When upgrading drive backplane configurations, you must install all 1.8-inch solid-state drive backplanes to the right of all 2.5-inch hard disk drive or

2.5-inch solid-state drive backplanes. All 2.5-inch backplanes must be installed to the left of all 1.8-inch backplanes.

3. If you install a 8x1.8-inch drive backplane assembly, the drive IDs that are indicated on the server front bezel will no longer be valid. Use the drive labels that come with the backplane to renumber the drive IDs on the bezel.

Chapter 2. Installing optional devices 51

4. When you install a combination of 2.5-inch and 1.8-inch drive backplanes in the same server, the drive bay ID numbering is reset by skipping bay ID numbers based on the number of 2.5-inch drive backplanes that are installed to the left of the 1.8-inch drives backplanes.

For example, if the server has a 4x2.5-inch drive backplane and a 8x1.8-inch backplane configuration, the drive bay IDs of the four drives in the 4x2.5-inch drive backplane are 0 through 3. The drive bay IDs of the eight drives in the 8x1.8-inch drive backplane starts with an ID of 8 through 15. Since the drive bay IDs of the drives in the 4x2.5-inch backplane are 0 through 3, the IDs reset and skip four ID numbers (because the first backplane supports four drives), then the drive IDs in the 8x1.8-inch drive backplane starts with an ID of 8 through 15.

If a 8x2.5inch drive backplane had been installed, instead of the 4x2.5-inch drive backplane, the IDs are reset and skip eight ID numbers, then the drive IDs of the drives in the 8x1.8-inch drive backplane would start at 16 through

23. See the following example illustrations and the illustrations in “Supported SAS/SATA drive backplane configurations” on page 53 for more information.

In the following illustration, the drive bay IDs are in sequential order because all of the drive backplanes are 2.5-inch drive backplanes.

In the following illustration, you have a combination of drive backplanes. This example shows a 2.5-inch drive backplane and a 1.8-inch drive backplane installed in the server. In this instance, the drive bay IDs will require a gap in the bay ID numbering between the drive IDs in the 2.5-inch and 1.8-inch drive backplanes.
