Scalable Symmetric Multiprocessing Servers

Express5800/A1160 systems are the next generation of symmetric multiprocessing

(SMP) servers that support multi-core Intel Xeon processors.

Figure 1-1 Express5800/A1160 Cell

Basic Building Block

Express5800/A1160 systems employ a modular building-block design. The basic building block is a cell—a standard 19-inch 4U rack-mounted server. A cell contains four processor sockets, six Peripheral Component Interconnect Express (PCIe) slots, 32

1-1

Operating Systems dual inline memory module (DIMM) sockets that support 2-GB or 4-GB fully buffered

DIMMs, and all the other components it needs to function as a self-contained computer system.

Modular Expansion

The cell-based building-block design allows Express5800/A1160 systems to grow as business needs evolve. By connecting cells together, you can expand an Express5800

Model 7600R system from 4 to 16 processor sockets. Memory expands from 2 to 128

DIMM sockets. With 4-GB fully buffered DIMMs, a cell can contain up to 128 GB of memory, and a 4-cell system can contain up to 512 GB of memory. The I/O subsystem expands from 6 to 24 PCIe slots and adding PCIe expansion modules can further increase the number of I/O slots. Hardware to connect the cells together is added only as the server size increases.

System Partitioning

Each cell in an Express5800/A1160 system can function as an independent partition. In multiple-cell systems, two or more cells can be combined into a single partition. Each partition can run an operating system different from the operating system in any other partition.

Customer Installation and Servicing

Express5800/A1160 systems are designed to be installed by the customer without any special tools or training. Likewise, no special tools or training are required to service customer-replaceable units (CRUs).

Reliability, Availability, and Serviceability

Express5800/A1160 systems contain many features to detect and isolate faults.

Systems with two or more cells provide 99.995% or better hardware availability.

Distributed System Management

Management controllers within each cell of an Express5800/A1160 system cooperate to provide management of the system. Hosted remotely, a server management application, such as NEC Server Management software, can monitor and control the system.

Operating Systems

1-3

Section 2 Cell Component

Express5800/A1160 Cell

In Express5800/A1160 systems, hardware components are organized into cells. The main components of a cell are

•

Main logic module that hosts the processors, processor voltage regulator modules, and node controller. (The node controller interconnects the components of a cell and provides the connection among the cells in a multiple-cell system.)

•

Memory board that contains the DIMM sockets for the fully buffered DIMMs.

•

I/O subsystem that includes the I/O riser board, PCIe carriers, and PCIe cards.

•

Peripherals including drive tray and hard drives, DVD drive, and Serial Attached

SCSI (SAS) RAID controller.

•

Management and maintenance components (EXPRESSSCOPE® Monitor and management board).

Figure 2-1 illustrates the main components of a cell.

2-1

Processors

Figure 2-1 Basic Cell

Processors

Within each cell, the processor board in the main logic module hosts the processors.

The processor board contains the processor sockets, processor voltage regulator modules, node controller, and the scalability ports, which are the ports that enable you to connect up to four cells.

Processor Sockets

Each cell contains four processor sockets. Four direct front-side buses provide the connections for the four processor sockets. Each direct front-side bus operates at 1067

MT/s.

2-2

Processors

Figure 2-2 shows the location of the processor sockets (along with the processor number) on the processor board.

Figure 2-2 Processor Socket Location on Processor Board

Supported Processors

Express5800/A1160 systems support the following Intel Xeon processor 7400 series

(Dunnington) processors:

•

Model E7440 (2.4 GHz with 2 x 3-MB L2 cache, 16-MB L3 cache, quad core, 1066

MHz front-side bus)

•

Model X7460 (2.66 GHz with 3 x 3-MB L2 cache, 16-MB L3 cache, hex core, 1066

MHz front-side bus)

Check with your sales representative for the availability of a specific processor.

Multicore Processors

Multicore processors contain four or six complete physical processors (cores) in the same integrated circuit. A quad-core processor (four cores) can appear as four logical processors, and a hex-core processor (six cores) can appear as six logical processors.

Extended Memory 64 Technology (EM64T)

The Xeon processors support the Intel EM64T technology. EM64T is an enhancement to the 32-bit Intel architecture. It allows a processor to run 64-bit code and access larger amounts of memory. Processors with Intel EM64T support 64-bit operating systems from Microsoft, SUSE, and Red Hat. Processors running in legacy or 32-bit mode remain fully compatible with existing 32-bit applications and operating systems.

Rules for Mixing Processors

Intel supplies different types, or families, of processors, such as the Intel Xeon processor family. In addition, processors within a given family can have different

2-3

Processors steppings. A stepping is a version of the processor that is associated with a set of fixes and errata.

When mixing processors or processor steppings, observe the following rules:

•

Each processor board (or each cell) supports only one processor family.

•

All processors in a partition must be the same frequency and have the same amount of cache.

Processor Voltage Regulator Modules

The processor board contains voltage regulator modules that convert the 12-volt DC from the power supplies to the voltage required by the processors.

Node Controller

The node controller provides scalability, native PCIe, and fully buffered DIMM memory for the Express5800/A1160 cell. It maintains coherency between the processors, memory, and I

O subsystem and contains extensive error detection and correction logic.

The node controller provides the following interfaces:

•

Four dedicated high-speed interconnect interfaces for the processor sockets (one interface for each socket).

•

Four fully buffered DIMM interfaces.

•

Three x8 PCIe interfaces

•

One x4 PCIe interface

•

Three high-speed serial interfaces that support 10 high-speed serial lanes in parallel for each direction for each interface. The interface enables a cell to be connected to up to three other cells using interconnect cables that run between the interconnect ports on the rear of the cell.

•

Enterprise South Bridge Interface (ESI) to the I/O controller hub (south bridge)

Figure 2-3 illustrates the node controller.

2-4

Memory

Figure 2-3 Node Controller

Memory

Express5800/A1160 systems use a directory-based cache-coherent memory system.

The directory-based memory tracks ownership of data. The cache coherency protocols force the processor cache components and main storage components to y Keep track of all copies of a cache line. y Determine which processor has permission to update an instance of a cache line. y Mark other copies of the cache line as "invalid" when an update occurs.

Memory Board. System memory is contained on the memory board. The memory board includes the fully buffered DIMMs and their associated power delivery components. A cell contains one or two memory boards. Each memory board supports y Two fully buffered DIMM channels from the node controller. Each channel operates as a single memory channel. These two channels are referred to as a channel pair.

2-5

Memory

Each channel pair operates in lockstep; that is, a single cache line is stored across two DIMMs with each DIMM on a different channel of the lockstep pair. y Eight fully buffered DIMM slots for each channel. A cell with two memory boards contains 32 DIMM slots. y Double Data Rate 2 533-MHz and 667-MHz fully buffered DIMMs (single, dual, or quad rank). y DIMM capacities of 2 GB or 4 GB. y Hot-add memory (requires operating system support).

Figure 2-4 shows the channels, channel pairs and fully buffered DIMMs on the memory boards.

Figure 2-4 Memory Boards

DIMM Slot Numbering

Figure 2-5 shows the numbering of the DIMM slots on the memory board relative to their physical layout on the board.

128 GB

Check with your sales representative for the availability of specific DIMMs.

Rules for Memory Expansion

Note the following rules when expanding system memory: y DIMMs must be installed in pairs. A pair consists of two identical fully buffered

DIMMs of the same speed, capacity, and number of ranks. y DIMMs must be loaded from the inside row of slots first before moving toward the outside row of slots. Do not leave an empty slot between two populated DIMM slots.

For the best performance, install two memory boards in a cell. Both memory boards should be populated with the same type of DIMMs and have the same memory capacity installed.

2-7

I/O Subsystem

Indicators on the Memory Board

The memory board contains a green LED to indicate that the board is in service and an amber LED to indicate that the board needs attention. Do not remove a memory board while the green LED is lit.

Dynamic DIMM Sparing

Dynamic DIMM sparing automatically substitutes a spare DIMM in place of an operational DIMM before a high rate of correctable errors leads to an uncorrectable error and loss of data. The cell maintains normal memory operations during the dynamic

DIMM sparing process.

In dynamic DIMM sparing, a DIMM, in the last populated slot and next to the last operational DIMM on the channel, must first have been reserved as a spare. Both channels must be populated with identical spare DIMMs in the equivalent slot positions on each channel.

Memory Mirroring

Mirroring is an optional memory addressing mode that provides protection against uncorrectable errors by maintaining two images of memory. With mirroring, all uncorrectable errors, including a complete DIMM or channel failure, will not stop the system.

Mirroring is between the two memory boards within the cell. (Mirroring between memory boards in different cells is not supported.) On detection of a memory failure, the system breaks the mirror and continues operation out of the remaining "good" memory board.

Once the mirror has been broken, you can remove the memory board with the failed

DIMM, replace the DIMM, reinstall the memory board, and reestablish mirroring.

I/O Subsystem

The I/O subsystem consists of the I/O riser board, PCIe cards, and the PCIe card carrier.

I/O Riser Board

The I/O riser board contains the following components: y Three PCIe-to-PCIe x8 switches with each switch supporting two PCIe card slots y Six PCIe slots which support the following features:

- Two full-length cards slots (slots 1 and 4) and four half-length card slots

- 25 watts per slot

- PCI Express Gen 1 (2.5 Gbps)

2-8

Each slot has its own power and attention indicators (LEDs). y Internal slot for PCIe Serial Attached SCSI (SAS) RAID controller

Figure 2-6 shows the I/O riser board.

I/O Subsystem

Figure 2-6 I/O Riser Board

PCIe Card Carrier

The PCIe card carrier enables an administrator or technician to insert or remove the

PCIe cards from the rear of the cell. Typically, a PCIe card plugs into a motherboard vertically. Vertical insertion requires access to the cards from the top of the cell. In a rack environment, this access requires rails in order to pull the cell forward, longer cables, and additional cable management.

The PCIe carrier turns the PCIe card connection 90 degrees. This configuration enables the administrator or technician to insert and remove the carrier while holding it horizontally. The technician or administrator places the PCIe card in the PCIe carrier and plugs the card and carrier into a connector on the I/O riser board from the rear of a cell. This configuration eliminates the need to access the cell from the top.

In addition, the cell includes the following ports on the management board: y Maintenance LAN port (10/100 Ethernet port) y USB management port y Management serial port

Figure 2-9 shows the location of the ports on the back of the cell.

Figure 2-9 Ports on Back of the Cell

Inbuilt RAID Controller

The inbuilt RAID controller supports 3 Gbps SAS drives and is compliant with x4 lane

PCI Express 1.0a. It supports the following disk configuration options: y RAID 0 (striping) y RAID 1 (mirroring) y RAID 5 (disk striping with distributed parity) y RAID 6 (disk striping with dual distributed parity) y RAID 10 (striped data across mirrored spans) y RAID 50 (distributed parity with disk striping)

2-11

Power

Each cell is independently powered. The power system is fully distributed and consists of the following components.

AC Connections

The AC input for each cell is two 15-ampere line cords. The line cords are connected to the power strips mounted in the rear of the cell.

AC/DC Power Supplies

The AC/DC power supplies take the AC input power and produce the DC power used by the cell components. Each cell contains two hot-pluggable AC/DC power supplies. The power supplies are rated for a maximum of 1800 watts at 200 volts or 1000 watts at 100 volts. Actual cell power consumption is significantly less and is determined by the system configuration and activity.

The output of the power supplies is 12 volts with a 3.3-volt keep-alive voltage for power control.

The power supplies are self-cooled.

Figure 2-10 shows the location of the two power supplies on the back of the cell.

Figure 2-10 Power Supplies

Power Supply Indicators

The power supplies have a green LED to indicate the state of the power supply and an amber LED to indicate a fault or failure in the power supply.

Power Control

2-12

Cooling

The main logic module contains the single master power controller for the cell. The master power controller y Controls and monitors the power supplies, and monitors the voltages on all cell components y Responds when someone presses the power button (to turn the power on or off) y Monitors and controls the fans y Monitors thermal sensors y Communicates with the management system

200-Volt Redundancy and AC Source Options

A second AC/DC 12-volt power supply provides n+1 DC redundancy. If one power supply fails, the cell can continue operating at normal levels with the other power supply.

A second AC source can be configured to provide AC redundancy. The two power supplies can also be configured for a non-redundant 100-volt operation.

In addition, with a second power supply, you can increase system availability by attaching each power supply to a different power source, for example, to a different uninterruptible power supply (UPS). If one power source fails or is interrupted, the cell continues processing using the other power source.

In a redundant 200V configuration, you can replace individual power supplies while a partition is running within that cell.

Partitions and Power

Partitions are made up of one or more cells. If a system contains multiple partitions, one partition can be powered off while the other partitions continue their processing.

Clustering software also helps ensure continuous processing.

Uninterruptible Power Supply (UPS)

UPSs help sites minimize system downtime caused by AC disturbances. A UPS uses batteries to provide AC to the system if the AC input is lost or disturbed. The length of time a system runs on a UPS depends on the capacity of the UPS and the amount of power the system needs.

The decision to provide alternate power sources, standby power generation, UPS, or a combination of these should be based on the economic consequences of a system interruption caused by a power outage or brownout (low voltage). A service representative can assist with this analysis.

2-13

Cooling

Each cell is cooled by two fan modules. Each fan module contains two 12-volt high-performance fans that provide the airflow required to cool the cell components and processors. The fan modules are mounted in the front of the cell.

Note: The power supplies within the cell are self-cooled.

The fans have four speeds. The system automatically adjusts fan speed based on the ambient and system component temperatures or under certain failure or maintenance conditions. If a fan fails or is removed, the system switches the remaining fans in the cell to high speed. The fans return to their normal speed when the failure condition is resolved.

The cooling system is n+1 redundant; that is, it can tolerate the failure of one fan. If two fans fail, the cell powers down. If a fan module is removed, the master power control turns off power to the cell after 2 minutes. This allows time for the fan or memory to be replaced.

The fans have a green LED that is on when the fan module is functioning properly. The green LED is off on a faulty fan module or if DC power is not applied to the cell. A fan module can be replaced by a customer.

Figure 2-11 shows the location of the fan modules on the front of the cell.

2-14

Peripherals

Figure 2-11 Fan Modules

Peripherals

The cell supports the following peripherals through the drive tray: y Six 2.5-inch Serial Attached SCSI (SAS) disk drives with one of the following capacities: y 73 GB (15000 RPM) y 146 GB (10000 RPM) y DVD drive (DVD-RW)

The drive tray also hosts the two USB ports on the front of the cell.

Figure 2-12 illustrates the peripherals on the drive tray.

2-15

Peripherals

Figure 2-12 Peripherals on the Drive Tray

Floppy disk drive support, if required, can be supplied through a floppy disk drive attached to the USB port. The BIOS also supports booting the system from any device attached to the USB port.

A keyboard and mouse can also be attached to the USB ports. In a system with multiple partitions, each partition can contain only one keyboard and mouse.

External Peripherals

A cell can also access, through the input/output system, a wide variety of peripherals that are external to the cell. Wide assortments of PCIe-based peripheral devices have been qualified for Express5800/A1160 systems. These include Fibre Channel controllers and adapters, disk subsystems (SCSI and Fibre Channel), LAN connectors,

SCSI controllers, SCSI RAID controllers, SCSI tape subsystems, serial controllers, tape libraries, and other controllers.

Because the list of qualified peripherals changes frequently, contact your sales representative for current information about qualified peripherals.

Boot Options

Express5800/A1160 systems provide the following boot options: y Internally from the SAS drives y Externally from SAS disk drives y Externally from Fibre Channel storage y Externally from SCSI storage y Externally from iSCSI storage

Express5800/A1160 systems are capable of being deployed in a preboot execution environment (PXE) provided that the external LAN connections exist at boot time. For more information about implementing this feature, see the Web site for your operating system vendor.

2-16

System Clocks

A clock synthesizer on the main logic module is the master clock source. This source provides a number of output clocks that are further distributed to the system components as needed.

The clock distribution system is self-contained within each cell. Systems with multiple cells do not provide redundant system clocks.

EXPRESSSCOPE® Monitor

Each cell contains an EXPRESSSCOPE® Monitor on the front of the cell. The

EXPRESSSCOPE® Monitor provides a control and display interface (LCD) for the cell and the partition containing that cell. It is primarily used to y View and update network settings for the partition. y View and update network settings for the cell. y Enable the trusted platform module (TPM) physically present attribute.

The EXPRESSSCOPE® Monitor consists of y LCD display screen of four lines that are 20 characters each. y Navigation buttons (up, down, left, and right) and a selection button (OK). y Cell identification (ID) button that specifies the cell in the display screen and lights the cell ID LED on the back of the cell. The ID button on either the front or back of the cell turns off the chassis identification.

Inbuilt virtualization is an optional capability for Express5800/A1160 systems. This capability enables a partition to boot with VMware Infrastructure 3. The partition contains a USB drive with a preloaded copy of the embedded version of VMware ESX 3.5. The

USB drive is attached to the compatibility hardware of the partition. When a partition that contains the USB drive is booted, the partition boots to VMware (unless a disk is in the

DVD drive).

The inbuilt virtualization option gives an enterprise the ability to always bring up a partition in a virtualized environment.

Trusted Platform Module (TPM)

Note: The TPM is an optional component. Contact your sales representative to determine if the cells in your system contain a TPM.

The TPM is a hardware security device that implements protected capabilities and shielded locations, which are used to protect and report integrity measurements as defined by the Trusted Computing Group specifications. The TPM also stores a limited number of cryptographic keys used to authenticate reported measurements. The TPM protected capabilities can include additional security functionality such as cryptographic key management, random number generation, and sealing data to system state.

The TPM is mounted on the management board and attached to the low pin count (LPC) bus (see Figure 4-2 ). The LPC bus connects low-bandwidth devices to the CPU.

In a multiple-cell partition, only one TPM can be active at a time. The active TPM is in the boot cell of the partition.

Your data center must use key management software to migrate any keys stored in the

TPM if the boot cell changes.

For More Information

See the following resources for more information about the TPM:

• Trusted Computing Group ( www.trustedcomputinggroup.org

)

• User's Guide for information about using the TPM.

Section 3 System Configuration

This section describes the packaging of Express5800/A1160 systems and the different configuration options.

Cell Interconnect and Multiple Cell Systems

A four-processor socket cell is capable of containing all the hardware it needs to boot as a server. To create a larger system, a cell can be connected together with up to three other cells using interconnect cables.

Interconnect Cables. The interconnect cables connect to the ports on the rear of the cell.

The interconnect cables have an A end (denoted by an amber band) and a B end

(denoted by a blue band). When creating a multiple-cell system, the correct end of each cable must be plugged into the appropriate interconnect cable port (0, 1, or 2). Figure

3-1 shows the interconnect cables and ports on the rear of the cell.

Figure 3-1 Interconnect Cables and Interconnect Cable Ports

Multiple-Cell Systems

A cell can be connected together with up to three other cells to create a multiple-cell system. > shows a system made up of two cells (eight processor sockets). The two cells are connected together with two interconnect cables. > shows a system made up of four cells (16 processor sockets). Systems with four cells require six interconnect cables.

Systems with three cells are also possible.

Figure 3-2 System with Two Cells

Figure 3-3 System with Four Cells

Cell Identification

Each cell in a system has a unique physical cell identifier-cell 0, cell 1, cell 2, or cell 3.

The management firmware uses the cell identifier to enable the cells within the system to communicate with each other.

The cell identifier is established by the interconnect cables. The cell identifier is based on which ends of the interconnect cables are connected to the interconnect ports on the back of the cell. Each interconnect cable has an "A" and a "B" end. Table 3-1 shows which cable end needs to be connected to the interconnect ports to create specific cell

IDs.

Table 3-1 Relation of Interconnect Port and Cable End to Cell ID

Cell ID Port 2 Port 1 Port 0

Cell 1 B A A

A cell without any cables connected to the interconnect ports is assumed to be cell 0.

To allow the correct cell identifier to be saved, a system must be completely cabled before the AC power is applied to the cells for the first time. Once established, the cell identifier is static.

The cell identifier is shown on the same label as the system serial number. See Figure

3-4 for the location of the label.

System Serial Number

The system serial number uniquely identifies each system. All cells within a system share the same system serial number.

A label with the system serial number is attached to each cell. Figure 3-4 shows the label location in the cell.

3-3

Cabinets

Figure 3-4 System Serial Number Label

Cabinets

Express5800/A1160 systems can be installed in any standard 19-inch-wide cabinet. You can either order a cabinet from NEC or provide your own. See the System Planning

Guide for the requirements for customer-provided cabinets.

Optionally, each system can have a directly connected keyboard, monitor, and mouse to serve as a system console.

Figure 3-5 shows the configuration of cells and other components in a cabinet.

3-4

Partitions

Figure 3-5 Cabinet Configuration

Partitions

You can configure one or more cells as a partition to support an instance of an operating system or a virtual machine monitor. A partition is a logical computer in the system. You use partitions to run user applications that perform work to support your business.

Each cell in the system can support one partition. Systems with four cells can support one to four partitions. See the User's Guide for the partitioning rules.

Clustering

When several partitions are configured, the servers become a convenient platform for clustering. Because partitions (or cluster nodes, in this context) are neatly contained in the same cabinet, cabling requirements are simplified. Also, because cluster nodes are derived from the same pool of hardware components, you can quickly reallocate

3-5

Redundant Configurations hardware resources among cluster nodes in response to planned and unplanned events.

This reallocation is virtually impossible to accomplish in a traditional cluster.

Clustering Software

Express5800 systems support various clustering paradigms, including shared disk clusters, and shared nothing (only interconnected) clusters.

Redundant Configurations

Redundant configurations ensure that Express5800 systems do not have a single point of failure. Redundancy y Improves the availability of the server if a component fails y Allows the removal of a failing component without stopping the server y Allows the removal of a failing component with an automatic reboot, if the operating system cannot remain running while the failed component is replaced

A system that consists of a single cell provides redundant power and cooling. Complete redundancy is provided in multiple- cell systems. Redundancy is available for the following hardware components: y Power supplies (n+1) y Memory y I/O

Replaceable Components

Replaceable components are hardware assemblies or subassemblies that can be replaced onsite to either upgrade the server or replace a failing component.

Hot-swappable components can be replaced when the power is on and the operating system is running. Hot-pluggable components can be replaced when the power is on but the operating system is stopped.

The cell contains both customer-replaceable components and field-replaceable components. When the management system detects a fault in the cell, it displays the component name on the control panel LCD. All customer-replaceable components can be replaced with the power on and the partition running. No special training or tools are required to replace a customer-replaceable component. Field-replaceable components require special handling and are replaced by service representatives.

Section 4 Server Management

This section provides an overview of the hardware and software components used to manage Express5800/A1160 systems.

System Components

The following illustration shows how the components are connected in a typical system environment.

Your system can include the following components.

4-1

Components on the Front of a Cell

Cells

A cell contains the physical resources of the system: instruction processors, memory, input/output devices, peripheral storage devices, management board, fans, power supplies, EXPRESSSCOPE® Monitor, and so on. Each system comprises one to four cells.

Maintenance LAN (MLAN)

The maintenance LAN (MLAN) connects the internal components of the system.

Partition

A partition is a combination of one to four cells that runs a single instance of an operating system or virtual machine monitor. The operating system can be Red Hat

Linux, SUSE Linux, or any supported Windows operating system. The virtual machine monitor can be VMware ESX or Xen. You can purchase the operating system or virtual machine monitor from NEC or supply it yourself.

A system comprises a minimum of one and a maximum of four partitions.

Service Processor

Each cell has an internal management board. For each partition, one of the partition’s management boards serves as the Service Processor. (Other management boards in the partition are called satellite management controllers.) A Service Processor manages and maintains the partition, monitors the system for hardware problems, and allows you to repartition the system.

The system’s management firmware resides on flash memory on the management board and provides the Service Processor functionality. Using a Web browser, you connect to the remote console interface to maintain, monitor, and repartition the system.

The management board also includes the BIOS and Console Manager firmware.

Network Components

Your network environment can include the following components.

Public LAN

The public LAN is the customer’s internal production network that connects the servers, workstations, and so forth of an enterprise. It is sometimes referred to as the enterprise

LAN.

4-2

Network Components

Windows Domain Controller

The domain controller typically acts as the Domain Name System (DNS), Windows

Internet Name Service (WINS), and Dynamic Host Configuration Protocol (DHCP) server.

Note: DNS and WINS servers must be made secure in accordance with local security policy guidelines. Microsoft recommends that production applications such as Server

Management software not be installed on domain controllers. For more information about domain controllers, see the appropriate Microsoft documentation.

Management Server

A management server that has Server Management software installed enables you to manage new Express5800 systems and monitor older Express5800 systems in your environment. A management server is necessary in order for your system to report problems to the NEC client support center using remote maintenance service requests.

The ESMPRO Manager is installed on the management server. It is designed to help you manage your enterprise at a glance.

Client Workstation

A client workstation enables you to remotely access management server functionality.

From a Web browser on the client workstation, you can also access the Remote

Console interface residing on the partition Service Processor. In addition, a client workstation can serve as a remote system console by accessing the KVMS Redirection page of the Partition Remote Console interface, which launches the Console Manager

Partition Desktop or JViewer interface.

Console Manager Client Software

Console Manager Partition Desktop and JViewer user interfaces enable you to manage partitions remotely, without the need for directly attached peripherals. Instead, you can use one or more network-connected workstations to view and control partitions. (These workstations can be the same as client workstations that have Server Management software installed or can be other workstations that meet the Console Manager requirements.) You can control the partition keyboard and mouse, view the partition operations, and share storage drives or storage images with the partition.

To control a partition remotely, you access the Partition Desktop or JViewer interface from the KVMS Redirection page of the remote console interface. (If your workstation is running a Windows operating system and Internet Explorer, you can use the Partition

Desktop. If your workstation is running either a Linux operating system or a Windows operating system with the required Java software, you can use JViewer.) The appropriate client software is downloaded to your workstation, and you can view or

4-3

Components on the Front of a Cell operate the partition.

Management Architecture

Management of Express5800/A1160 systems is based on a modular, distributed, and scalable architecture. This architecture distributes the processing load among various processing engines and grows as the size of the system increases.

Intelligent Platform Management Interface

Express5800/A1160 systems implement the message-based Intelligent Platform

Management Interface (IPMI) version 2.0 with extensions to support the partitioning of multiple-cell systems. IPMI is an industry-standard specification that defines a set of common interfaces to computer hardware and firmware which system administrators use to monitor system health and to manage the system.

Main Components

Management of Express5800/A1160 systems consists of both hardware and software components. The main hardware component is the management board, which contains the Service Processor and other components. Software components include the management firmware, management firmware Web interfaces, and the BIOS.

External management platforms, such as a management server or a workstation, enable system administrators to manage the system when the operating system network drivers or the partition are not functioning properly. External management platforms also provide access to additional features and third-party software.

Figure 4-1 illustrates the management architecture of Express5800/A1160 systems.

4-4

Management Board

Figure 4-1 Management Architecture

Management Board

The management board in each cell is the main hardware component of server management. Figure 4-2 illustrates the management board.

4-5

Components on the Front of a Cell

Figure 4-2 Management Board

The following paragraphs describe the main components on the management board in more detail.

Service Processor

The Service Processor is a management controller. For Express5800/A1160 systems, the Service Processor y Executes the management firmware to provide the management and maintenance capabilities y Provides access and control to the hardware units in the cell y Provides connections to the Service Processors in the other cells in a system

The Service Processor runs on keep-alive power so it is functional whenever AC power is applied to the cell.

The Service Processor also includes a flash card for storing system information and other data.

Firmware Hub

4-6

Remote Console Interfaces

The firmware hubs in each cell store the BIOS. The firmware hub and the TPM are attached to the low pin count (LPC) bus, an internal bus that connects low-bandwidth devices to the CPU.

Trusted Platform Module (TPM)

"Trusted Platform Module (TPM)" in Section 2 describes the TPM.

Ports

The management board contains the following ports: y 10/100 Ethernet ports - An Ethernet LAN is the physical transport for the internal communication among Service Processors in different cells and for communication with external management platforms. The 10/100 LAN connection on the Service

Processor connects to an Ethernet switch. Three ports on the Ethernet switch connect to the interconnect ports and, through the interconnect cables, to the

Service Processors in other cells. Part of the interconnect cable is the maintenance

LAN that is used to communicate with the Service Processors in a system.

One port from the Ethernet switch is routed to the Ethernet port (RJ-45 connector) that provides an external LAN connection. In a multiple-cell system, only one external LAN connection is needed. For redundancy, you can also connect the external LAN connections in the other cells to the external network. y 9-pin serial port y 15-pin SVGA (video) port

Other Management Logic

The management board contains other associated logic-such as the interface to the control panel-and access to the scan, clocking, and power management subsystems.

Remote Console Interfaces

Management firmware is a comprehensive means of configuring, controlling, and monitoring individual components of the Express5800/A1160 system and the system as a whole. Management firmware runs on the Service Processor.

The remote console interfaces are client user interfaces to management firmware that are provided by Web servers running on Service Processors. You can access Web interfaces using a browser on any device that is connected to the maintenance LAN that supports the Express5800/A1160 system.

Different remote console interfaces (sets of Web pages) control each partition, each cell, and the system as a whole. Each remote console interface provides commands to view information and update settings for that component.

For More Information

4-7

Components on the Front of a Cell

BIOS

See the User's Guide for more information about the remote console interfaces.

The BIOS is bootstrapping software that initializes and configures the hardware

(processors, memory, I/O, and so on) in the partition. Running in the partition, the BIOS provides many configuration, setup, diagnostic, and recovery functions.

In Express5800/A1160 systems, the BIOS is stored in the firmware hub in each cell.

Server Management Software

Server Management software enables a centralized operations environment for your systems. This software provides world-class data center management capabilities for greater business continuance and system resiliency. It can dramatically enhance the manageability, availability, and performance of your systems while considerably reducing total cost of operations.

Server Management software simplifies system management, automates corrective and preventive measures to avoid system failure, and increases the reliability, scalability, and performance of NEC systems.

Hardware Components

Server Management software manages and monitors Express5800/A1160 systems.

You can also use this software to monitor other Express5800 systems in your environment.

Server Management software can be installed on the following hardware components: environment to manage your new and existing Express5800 systems. A management server with Server Management software is necessary in order for your systems to report problems to the support center using Remote Monitoring service requests. servers. remote access to your management server.

Management Software Components

The Server Management software includes the following components.

ESMPRO Manager and Agent

Server Management software includes ESMPRO Manager and ESMPRO Agent software.

ESMPRO Manager enables a system administrator to manage a network by monitoring system hardware and software configurations, system failures, and system performance.

With log data collected by ESMPRO Manager, a system administrator can track

4-9

Components on the Front of a Cell long-term and short-term performance, monitor usage, create graphs to record trends, and check failure rates. System administrators can use the information collected to create more efficient data routing procedures and optimize server and partition usage.

ESMPRO Manager is installed on the management server along with other Server

Management software.

ESMPRO Agent is installed on servers and partitions running Windows, Linux, and

VMware ESX Server. ESMPRO Agent monitors software and firmware and uses SNMP to transmit the information to ESMPRO Manager. ESMPRO Agent enables the system administrator to view system settings and reset some ESMPRO Agent thresholds locally.

ESMPRO Manager and Agent use five graphical user interfaces: launch other management tools.

Agent. y Agent Control Panel - Enables you to configure operational settings for ESMPRO

Agent.

Remote Monitoring

Remote Monitoring enables you to monitor the generation and delivery of service request packets to the NEC Support Center. These packets contain information on system or controller errors that are determined according to a predefined set of conditions.

Internet access is the method for Remote Monitoring to communicate with the NEC

Support Center. Using this communication path to the NEC Support Center is beneficial because a modem and an additional phone line are not required. Remote Monitoring is installed on the management server, which enables the delivery of service events from a centralized location. Therefore, only one connection to the NEC Support Center is required rather than a separate connection for every system on which Remote

Monitoring is installed.

Note: If configuring direct Internet access conflicts with your corporate security policy, you can configure access through an Internet proxy server.

Accessing Remote Monitoring

You configure Remote Monitoring during the Server Management software installation process.
