Chapter 1. Introduction

The IBM

ERserver

BladeCenter™T Types 8720 and 8730 units are rack-mounted, high-density, high-performance blade server systems developed for NEBS telecommunications network applications and other applications requiring physical robustness.

The BladeCenter T unit uses blade servers, switches, and other components that are common to the IBM BladeCenter product line. This common component strategy makes it ideal for applications in telecommunications networks that need high levels of computing power and access to common off-the-shelf middleware packages that are used in IT data centers. The BladeCenter T unit supports up to eight blade servers and four I/O modules, making it ideally suited for networking environments that require a large number of high-performance servers in a small amount of space. The BladeCenter T unit provides common resources that are shared by the blade servers, such as power, cooling, system management, network connections, backplane, and I/O (CD-ROM drive and connectors for USB, keyboard, video, mouse, and network interfaces).

Performance, ease of use, reliability, robustness (NEBS/ETSI compliance), and expansion capabilities were key considerations in the design of the BladeCenter T unit. These design features make it possible for you to customize the system hardware to meet your needs today, while providing flexible expansion capabilities for the future.

BladeCenter T

What the BladeCenter T unit offers

The design of the BladeCenter T unit takes advantage of advancements in server technology. It provides up to eight functionally separate servers and their shared resources in a single center. The BladeCenter T unit with blade servers installed has the following features:

IBM Enterprise X-Architecture

IBM Enterprise X-Architecture technologies to build powerful, scalable, reliable Intel™-processor-based servers. Enterprise X-Architecture technology includes features such as light path diagnostics, Predictive Failure Analysis (PFA), scalability, and Real Time Diagnostics.

Expansion capabilities

You can add blade servers to the BladeCenter T unit as needed, to a maximum

eight blade servers.

Note: If any blade server or option is in blade bay 5 through 8 or if an I/O

module is in I/O-module bay 3 or 4, power modules must be present in all four power-module bays.

Some blade servers have connectors for options that add capabilities to the blade server, such as an I/O expansion card to add a network interface, or a storage expansion unit to add SCSI hard disk drives.

Hot-swap capabilities

The front bays on the BladeCenter T unit are hot-swap blade, power-module, and management-module bays; the rear bays on the BladeCenter T unit are hot-swap I/O, KVM, LAN, and blower-module bays. You can add, remove, or replace blade

™

servers or power, management, I/O, KVM, LAN or blower modules in hot-swap bays within specified time limits and without removing power from the BladeCenter T unit. See Chapter 3, “Removing and installing BladeCenter T modules and options,” on page 25 for detailed instructions.

Attention: To maintain proper system cooling, each unoccupied bay must

contain a filler blade or filler module.

Redundancy capabilities

The following redundant components in the BladeCenter T unit enable continued operation if one of the components fails:

Power modules: In normal operation, the redundant power modules provide redundant power feeds to share the system load. If one of the power modules fails, the working power module handles the entire load. You can then replace the failed power module without shutting down the BladeCenter T unit.

Blowers: In normal operation, the redundant blower modules share the system load. If one of the blowers fails, the other three working blowers handle the entire load. You can then replace the failed blower without shutting down the BladeCenter T unit.

Management modules: Only one management module is active at a time. If a second management module has been installed and the active management module fails, the secondary (redundant) management module becomes the active management module containing the current BladeCenter T configuration and status information. You can then replace the failed management module without shutting down the BladeCenter T unit.

BladeCenter T backplane characteristics: The backplane has the following redundancy characteristics:

Hot-pluggable connectors for the following components:

Eight blade servers Four I/O modules Two management modules Four power supplies Four blowers

Redundant high-speed SERDES interconnects between blade servers and

switches

Support for redundant management modules

Redundant I2C communications between management modules and all modules (except the blade servers)

Redundant RS-485 communications between management modules and blade servers

Redundant analog video connections from blade servers to management modules

Redundant USB connections between blade servers and management modules

Redundant, secure Ethernet management port between switches and management modules

Redundant network connection capabilities

Configuring a pair of Ethernet switch modules in I/O-module bays 1 and 2 provides support for Ethernet failover configured on blade servers. See “Configuring an I/O module” on page 68 for more information. If the I/O expansion options in your blade servers can be configured for failover,

Chapter 1. Introduction

configuring a pair of switch modules in I/O-module bays 3 and 4 provides support for the failover configured on the I/O expansion options.

Note: A system configuration with I/O expansion options in I/O-module bays 3

and 4 requires a unit configuration with power supplies in power-module bays 3 and 4.

Other network-interface I/O expansion options, such as the IBM BladeCenter Fibre Channel Expansion Card, can have similar capability for redundant network connections. See the documentation that comes with the I/O expansion module and I/O module for more information about configuring for redundant network connections.

System-management capabilities

The BladeCenter T unit comes with a service processor in the management module. The service processor in the management module, the system-management firmware that is provided with your BladeCenter T unit, and the service processor in each blade server, enable you to remotely manage the BladeCenter T unit, its components, and the blade servers. The management module also multiplexes the keyboard, mouse, and video ports and the USB port across the multiple blade servers.

The service processor in each blade server provides blade server system monitoring, event recording, and alert capability.

See Chapter 5, “Configuring the BladeCenter T unit,” on page 61 for more information.

Network environment support

This BladeCenter T unit supports up to two Ethernet-compatible I/O modules (switch modules or pass-thru modules), for blade server integrated Ethernet controller communication with the network. Each I/O module provides one internal connection to each blade server, up to eight internal connections per I/O module.

The BladeCenter T unit also supports two additional I/O modules, for a total of four I/O modules. The two additional I/O modules support the network interface

the optional I/O expansion card installed on one or more blade servers in the

BladeCenter T unit.

Note: The two additional I/O modules must be compatible with the network

interface on the optional I/O expansion cards in the blade servers.

Each of these two additional I/O modules provides one internal connection to the optional I/O expansion card, up to eight internal connections per I/O module.

Reliability, availability, and serviceability features

Three of the most important features in server design are reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data that is stored on your blade server; that your blade server is available when you want to use it; and that should a failure occur, you can easily diagnose and correct the failure with minimal inconvenience.

The BladeCenter T unit has the following RAS features:

Shared key components, such as power, cooling, backplane, and I/O All components serviced from the front or rear of the BladeCenter T unit Automatic error retry and recovery Automatic restart after a power failure Built-in monitoring for blower, power, temperature, and voltage Built-in monitoring for module redundancy Customer support center 24 hours a day, 7 days a week Error codes and messages Fault-resistant startup Remote system management through the management module Remote management module firmware upgrade Remote upgrade of blade server service processor microcode Built-in self-test (BIST) Predictive Failure Analysis (PFA) alerts Redundant components

Option installation guidelines

Before you begin to install options in the BladeCenter T unit, read the following information:

Read the safety information beginning on page vii and the guidelines in “Handling static-sensitive devices” on page 17. This information will help you work safely with your BladeCenter T unit and options.

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

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

Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped, which means that you can remove or install the component while the BladeCenter T unit is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing

installing a specific hot-swap component for any additional procedures that

you might have to perform before you remove or install the component. You do not have to disconnect the BladeCenter T unit from power to install or

replace any of the hot-swap modules in the BladeCenter T unit. You must shut down the operating system and turn off a hot-swap blade server on the front of the BladeCenter T unit before removing the blade server, but you do not have to shut down the BladeCenter T unit itself.

For a list of supported options for your server, go to http://www.ibm.com/pc/compat/.

System reliability considerations

BladeCenter T Types 8720 and 8730: Installation and User’s Guide

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To

avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

Use an ESD wrist strap and the ESD connectors on the BladeCenter T unit. Electrostatic discharge (ESD) is the release of stored static electricity that can damage electric circuits. Static electricity is often stored in your body and discharged when you come in contact with an object with a different potential. The ESD wrist strap safely channels the electricity from your body to a proper ground (the BladeCenter T unit).

Use an ESD wrist strap whenever you are working on the BladeCenter T unit, especially when you are handling modules, options, and blade servers. To work properly, the wrist strap must have a good contact at both ends (touching your skin

one end and connected to the ESD connector on the front or back of the

BladeCenter T unit).

v Do

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

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

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

not touch solder joints, pins, or exposed printed circuitry. not leave the device where others can handle and damage it.

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

Remove the device from its package and install it directly into the system unit without setting the device down. If it is necessary to set down the device, place it back into its static-protective package. Do not place the device on the system unit or on a metal surface.

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

Removing and installing I/O modules

For blade server communication with the network, the BladeCenter T unit supports

four hot-swap I/O modules. Table 3 identifies the types of I/O modules that you can install in each I/O-module bay. Go to the IBM Support Web site at http://www.ibm.com/pc/support/ to see the list of supported I/O modules.

The BladeCenter T unit supports a minimum of one hot-swap Ethernet switch module or pass-thru module, in I/O-module bay 1 or 2. This I/O module provides an internal connection to an integrated Ethernet controller in all the blade servers in the BladeCenter T unit, up to eight internal connections per I/O module. To provide an internal connection for the second integrated Ethernet controller in each blade server, install an Ethernet switch module or pass-thru module in the available I/O-module bay of the pair (I/O-module bay 1 or bay 2). The management modules are connected to the switch module through the backplane using a transformerless 100 Mbps connection and an I2C interface.

The BladeCenter T unit supports two additional I/O modules in I/O-module bays 3 and 4. Each of these I/O modules provides an internal connection to one of the two network-interface controllers on each of the I/O expansion options that are installed

blade servers in the BladeCenter T unit. The I/O module must be compatible with the network interface on each of the I/O expansion options. For example, if you install a Fibre Channel I/O expansion card on a blade server, the I/O modules that you install in I/O-module bays 3 and 4 must be Fibre Channel switch modules or pass-thru modules.

Important: The switch modules in I/O module bays 3 and 4 and all blade server

interface options in the BladeCenter T unit, must use the same interface type. For example, if you install an Ethernet interface option on a blade server, the switch modules that you install in I/O module bays 3 and 4 must be Ethernet. All other interface options in the BladeCenter T unit must also be Ethernet interface options.

Note: You can use a pass-thru module in any I/O-module bay, provided that the

associated controller in the blade servers or I/O expansion options is compatible with it.

The following table summarizes the types of modules that can be used in each I/O-module bay. See “Rear view” on page 55 for the location of the I/O-module bays

Notes:

The enumeration of the Ethernet controllers in a blade server is operating-system dependent. You can verify the Ethernet controller designations that a blade server uses through your operating-system settings.

The routing of an Ethernet controller to a particular I/O-module bay depends on the type of blade server. You can verify which Ethernet controller is routed to which I/O-module bay by using the following test:

Install only one Ethernet switch module or pass-thru module, in I/O-module bay 1.

Make sure that the ports on the switch module or pass-thru module are enabled (I/O Module Tasks

Blade servers

The BladeCenter T unit supports up to eight high-performance blade servers. Each blade server is an enclosure that contains microprocessors, memory, a control chip set, an I/O bus, Ethernet controllers, hard disk drives or flash drives, and user-interface controls, and connectors for expansion options. The blade server receives its power, network connection, and I/O devices (CD-ROM, keyboard, mouse, and video ports, USB port, remote monitoring port) from the BladeCenter T unit, reducing the number of cables that are required.

Blade server expansion options

Some blade servers contain connectors for options that add capabilities to the blade server. You can add these options before installing the blade server in the BladeCenter T unit.

http://www.ibm.com/pc/compat/ for a list of available options for your IBM

blade server.

I/O expansion option

Some blade servers have connectors for adding an I/O expansion option, such as

IBM BladeCenter Fibre Channel Expansion Card. The BladeCenter T unit routes

network communication signals from the I/O expansion option to I/O modules 3 and

the BladeCenter T unit. The I/O expansion option is attached directly to the

Chapter 5. Configuring the BladeCenter T unit

The BladeCenter T unit automatically detects the modules and blade servers that are installed and stores the vital product data (VPD). When the BladeCenter T unit

started, the management module automatically configures the remote

management port on the management module, accessed through the LAN module

the rear of the BladeCenter T unit, so that you can configure and manage the

BladeCenter T unit and blade servers. You configure and manage the BladeCenter

unit remotely, through the management module, using the Web-based user

interface.

Note: There are two ways to configure the switch modules; through the

management-module Web interface, or through an external switch-module port enabled through the management module, using a Telnet interface or a Web browser. See the documentation that comes with the switch module for more information.

For the active management module to communicate with the I/O modules in the BladeCenter T unit, you must configure the IP addresses for the following internal and external ports:

Because all blade servers in the BladeCenter T unit share access to the external LAN through the switch ports, you can configure the ports on a switch module to operate together as an aggregate link, or trunk. An aggregate link provides more bandwidth than a single link to the attached LAN.

Notes:

The attaching LAN switch must have a compatible multiport trunk configuration. Configure link aggregation before you attach cables between the external ports

and your LAN equipment.

Configure the switch through the user interface on the switch module, which you can access through the Web interface to the management module (click I/O

Important: For a remote management station, such as a management server, to

communicate with the switch modules in the BladeCenter T unit, the management port of the switch module must be on the same subnet as the management module.

Supporting Ethernet failover

have the BladeCenter T unit support Ethernet failover on the blade servers, set

the BladeCenter T unit and blade servers as follows:

Configure the Ethernet controllers in one or more blade servers for failover (see the blade server documentation and the operating-system documentation for information). When failover occurs on a blade server, the secondary Ethernet controller takes over network communication, using the I/O module associated with that controller.

Install a switch module or a pass-thru module that is connected to external Ethernet switches in both I/O-module bays 1 and 2.

Configure the Ethernet switch modules and your network infrastructure so that they can direct traffic to the same destinations.

Configuring the Ethernet controllers in the blade servers

Note: The BladeCenter T unit does not include an Ethernet switch module; this is

optional feature that must be purchased separately. An Ethernet switch module or a pass-thru module is connected to an external Ethernet switch must be installed in the BladeCenter T unit in I/O-module bay 1 or 2, or both, before the integrated Ethernet controllers on each blade server system board can be used.

The Ethernet controllers are integrated on each blade server system board. The Ethernet controllers provide 1-Gbps full-duplex capability only, which enables simultaneous transmission and reception of data to the external ports on the Ethernet switches. You do not need to set any jumpers or configure the controller for the blade server operating system. However, you must install a device driver on the blade server to enable the blade server operating system to address the Ethernet controller. For blade server device drivers and information about configuring the Ethernet controllers, see the Ethernet software CD that comes with your blade server.

Chapter 5. Configuring the BladeCenter T unit

BladeCenter T networking guidelines

Your networking administrator should assist in the configuration of the network infrastructure before you connect the BladeCenter T unit to a LAN switch or similar network device. This section provides additional guidelines that might be useful in setting up your system.

BladeCenter T unit with two Ethernet switch modules and one management

module has the internal configuration that is shown in the following illustration:

Each blade server has two independent Ethernet controllers, each with its own MAC address and a dedicated 1 Gbps link to one of the switch modules in I/O module bays 1 and 2 (controller 1 to switch A and controller 2 to switch B in the illustration). In this configuration (the default), the blade servers share access to four external ports on each switch. There is no internal data path between the two switches within the BladeCenter T unit; an external network device is required for data packets to flow from one internal switch to the other.

The management module has a separate internal 100 Mbps link to each switch. These links are for internal management and control only. No data packets are allowed to flow from application programs on the blade servers to the management module over this path. A separate, nonswitched path (not shown) is used for communication between the management module and a service processor on each blade server.

In this configuration, each BladeCenter T unit contains two Ethernet switch modules and one management module. The external ports on the switch modules are configured for multiport link aggregation groups, or trunks, as are the corresponding ports on the attached external LAN switches. Additionally, every port in the switch module in I/O-module bay 1 (switch A in this illustration) in the BladeCenter T units

communicate with the BladeCenter T unit, the IBM Director software needs a managed object (in the Group Contents pane of the IBM Director Management Console main window) that represents the BladeCenter T unit. If the BladeCenter T management-module IP address is known, the network administrator can create an IBM Director managed object for the unit. If the IP address is not known, the IBM Director software can automatically discover the BladeCenter T unit (out-of-band, using the Ethernet port on the management module) and create a managed object for the unit.

IBM Eserver BladeCenter T Planning and Installation

BladeCenter T Types 8720 and 8730: Installation and User’s Guide

For the IBM Director software to discover the BladeCenter T unit, your network must initially provide connectivity from the IBM Director server to the BladeCenter T management-module Ethernet port. To establish connectivity, the management module attempts to use DHCP to acquire its initial IP address for the Ethernet port.

the DHCP request fails, the management module uses a static IP address. Therefore, the DHCP server (if used) must be on the management LAN for the BladeCenter T unit.

Notes:

All management modules are preconfigured with the same static IP address. You can use the management-module Web interface to assign a new static IP address for each BladeCenter T unit. If DHCP is not used and you do not assign a new static IP address for each BladeCenter T unit before attempting to communicate with the IBM Director software, only one BladeCenter T unit at a time can be added onto the network for discovery. Adding multiple units to the network without a unique IP address assignment for each BladeCenter T unit results in IP address conflicts.

For switch communication with the IBM Director server through the management-module external Ethernet port, the switch-module internal network interface and the management-module internal and external interfaces must be

the same subnet.

Chapter 7. Sharing resources among the blade servers

The IBM

Eserver

BladeCenter T Type 8720 or 8730 unit provides resources that are available to all blade servers at all times, such as power modules, cooling, system management, and network I/O modules; no user intervention is required. Some resources are selectable for use by a single blade server at a time, such as the CD-ROM drive, USB port units (media tray), or the keyboard-video-mouse (KVM) module. There are several ways to select resources for a blade server:

Each blade server has two selection buttons on the front of the blade:

and

switch the keyboard, video, and mouse to a specific blade server, press

the

button on that blade server.

switch the CD-ROM and USB ports to a specific blade server, press the

button on that blade server.

The management module immediately assigns the resource to the blade server requesting it.

You can use the management module Web interface to change ownership of the keyboard, video, and mouse, or the CD-ROM drive, and USB ports (Blade tasks→ Remote control).

You can press keyboard keys in the following sequence to switch KVM control between blade servers:

you install Microsoft Windows 2000 on a blade server while it is not the current owner of the keyboard, video, and mouse, the first time the blade server requests ownership after the operating system has been installed, it can take up

minute for the operating system to recognize the devices (this is a

one-time-only occurrance). The operating system in the blade server must provide USB support for the

blade server to recognize and use the keyboard, mouse, and CD-ROM drive. The BladeCenter T unit uses USB for internal communication with these devices.

You can use the management-module Web interface to enable or disable the select buttons (Blade tasks→ Remote control) on the blade servers.

The monitor attached to the BladeCenter T management module normally shows the video output from the blade server that is the current owner of the keyboard, video, and mouse (KVM). When there is no actively selected video from any blade server, the video from blade server 8 is routed to the management module. While the management module is restarting, there is temporarily no current KVM owner. The video from blade server 8 displays on the monitor briefly until the management module uses its NVRAM values to

reestablish ownership of the KVM and media tray (CD-ROM drive, and USB ports). After that, the video from the blade server that is the current KVM owner

displayed on the monitor.

Attention: Do not switch the CD-ROM drive, and USB ports to another blade

server while a transaction is taking place on the CD-ROM drive. (Activity lights on the CD-ROM drive must be off.) Data damage can occur.

failure resulting from misuse (including but not limited to use of any Machine capacity or capability, other than that authorized by IBM in writing), accident, modification, unsuitable physical or operating environment, or improper maintenance by you;

failure caused by a product for which IBM is not responsible; and

any non-IBM products, including those that IBM may procure and provide with or integrate into an IBM Machine at your request.

The warranty is voided by removal or alteration of identification labels on the Machine or its parts.

IBM does not warrant uninterrupted or error-free operation of a Machine. Any technical or other support provided for a Machine under warranty, such as

assistance via telephone with “how-to” questions and those regarding Machine set-up and installation, is provided WITHOUT WARRANTIES OF ANY KIND.

How to Obtain Warranty Service

the Machine does not function as warranted during the warranty period, contact IBM or your reseller to obtain warranty service. If you do not register the Machine with IBM, you may be required to present proof of purchase as evidence of your entitlement to warranty service.

What IBM Will Do to Correct Problems

When you call for service, you must follow the problem determination and resolution procedures that IBM specifies. A technician will attempt to make an initial diagnosis

your problem and help you resolve it over the telephone.

The type of warranty service applicable to your Machine is specified in Part 3 Warranty Information.

You are responsible for downloading and installing designated Machine Code (microcode, basic input/output system code (called “BIOS”), utility programs, device drivers, and diagnostics delivered with an IBM Machine) and other software updates from an IBM Internet Web site or from other electronic media, and following the instructions that IBM provides.

your problem can be resolved with a Customer Replaceable Unit (“CRU”) (e.g., keyboard, mouse, speaker, memory, hard disk drive and other easily replaceable parts), IBM will ship these parts to you for replacement by you.

the Machine does not function as warranted during the warranty period and your problem cannot be resolved over the telephone, through your application of Machine Code or software updates, or with a CRU, IBM or your reseller, if approved

IBM to provide warranty service, will either, at its discretion, 1) repair it to make it function as warranted, or 2) replace it with one that is at least functionally equivalent. If IBM is unable to do either, you may return the Machine to your place

purchase and your money will be refunded.

IBM or your reseller will also manage and install selected engineering changes that apply to the Machine.

Exchange of a Machine or Part

When the warranty service involves the exchange of a Machine or part, the item IBM or your reseller replaces becomes its property and the replacement becomes yours. You represent that all removed items are genuine and unaltered. The replacement may not be new, but will be in good working order and at least functionally equivalent to the item replaced. The replacement assumes the warranty service status of the replaced item.
