1 Introduction This chapter describes the HP NetServer AA server, the server with ComputeThru TM technology that enables the server to continue computing even when system components fail. This chapter provides a conceptual overview of the server, introduces HP NetServer AA terminology, and describes the components of a server. This chapter contains the following sections: Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 HP NetServer AA Components . . . . . . . . . . . . . . . . . .
Chapter 1 Introduction Introduction HP’s NetServer AA server is a fault tolerant Microsoft Windows NT server that provides Constant Computing TM, mirrored data storage, and uninterrupted network access. The server integrates standard Intel Pentium-based systems, standard Windows NT operating system, and HP’s patented technology to offer a fault tolerant server that runs Windows NT-compatible applications.
Chapter 1 Introduction Table 1-1 HP NetServer AA Server Benefits Benefit Description Redundant, fault tolerant processing and I/O subsystem The server uses redundant hardware and Endurance software to ensure that your server remains operational even in the event of a failed processor, a memory failure, an I/O failure (even those associated with I/O controllers), a disk drive failure, or a failed Ethernet adapter.
Chapter 1 Introduction Table 1-1 HP NetServer AA Server Benefits (Continued) Benefit Description Automatic reconfiguration When a fault condition occurs, or after that fault is corrected and the failed component is returned to service, the server automatically reconfigures and, if needed, synchronizes the components affected by the fault.
Chapter 1 Introduction HP NetServer AA Components Figure 1-1 shows the HP NetServer AA components. Table 1-2 describes each component in detail. The server hardware requirements are described in Chapter 2 in HP NetServer AA Solution Installation Guide. Other terms and industry-standard terms are described in the Glossary.
Chapter 1 Introduction Table 1-2 HP NetServer AA Components HP NetServer AA Server Contains . . . Component Description CE Each CE (Compute Element) is a Pentium class system that includes a motherboard, video adapter, a MIC (Marathon Interface Card), and two processors. The processors on the CE provide the compute processing for the server. 2 ESI The Endurance System Interconnect (ESI) is a conceptual term used to describe the fiber paths that connect the IOPs to the CEs.
Chapter 1 Introduction HP NetServer AA Server Overview The server operates as a standard Windows NT server while offering a complete fault tolerant operating environment. The server implements the standard Windows NT operating system. Because of this, the server supports any off-the-shelf and custom applications that are compatible with Windows NT without requiring any scripts or API support.
Chapter 1 Introduction Each system in the server (Figure 1-2) performs specific tasks, functioning as either a CE or IOP: • CE (Compute Element) contains the server CPU (s) and memory that supports the Windows NT operating system and applications. Because there are two CEs, the CEs provide the redundant CPU (s) and memory for the server. • IOPs (I/O Processors) contain the keyboard and mouse, mirrored SCSI devices, redundant network adapters, and other I/O devices.
Chapter 1 Introduction Endurance Software Endurance software integrates and synchronizes processing across four industry-standard Pentium class systems. All components are capable of multiprocessing, forming a logical, fully redundant, fault tolerant server. This results in the Windows NT operating system, all applications, and the local area network logically perceiving the integrated systems in the server as a standard Windows NT server.
Chapter 1 Introduction Software also includes the following: • Automatic disk mirroring. This ensures that data on mirrored SCSI disks are automatically maintained, and that data on mirrored disks are accurate and current. • Redundant network connectivity. The server uses redundant network connections (one on each IOP). The software detects any physical network adapter or connectivity failures. If a failure occurs, the redundant adapter automatically controls the flow of all network traffic.
2 HP NetServer AA Overview This chapter provides an overview of the server, including the boot process and state information. This chapter assumes that you are familiar with the terminology described in the Introduction and the Glossary. This chapter includes the following sections: Overview . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 HP NetServer AA Boot Process IOP Multi-Boot Options . . . . . . . . . . . . . . . . . . . 17 . . . . . . . . . . . . . . . . . . . . . . .
Chapter 2 HP NetServer AA Overview Overview The server is a fully redundant, fault tolerant server that provides continuous computing and redundant I/O devices for your Windows NT server and its applications. You can monitor and manage your server using Endurance Manager, a GUI-based management application. Using Endurance Manager, you can: • View the status of a server and its components. This includes the CEs, IOPs, MICs, interconnects, and all redirected devices.
Chapter 2 HP NetServer AA Overview In addition to the concepts described in Chapter 1, the fault tolerant technology coordinates all I/O requests and responses between the CEs and IOPs using the ESIs and the IL, as shown in Figure 2-1. • • In the server, the ESIs (Endurance System Interconnects) provide the interconnect paths for all server I/O requests and responses. These paths connect the IOPs to the CEs as follows: - ESI11 is the path from IOP1 to CE1. - ESI12 is the path from IOP1 to CE2.
Chapter 2 HP NetServer AA Overview Virtual Network In addition to the networking described above, the server includes a virtual network that provides LAN-style connectivity between the CE and each IOP. This connectivity is independent of any public (redirected) or private (IOP) network adapters. Within this virtual network, the IOPs and CE appear as three interconnected nodes, as shown in Figure 2-2. Figure 2-2 The Virtual Network Each IOP to CE virtual network is a separate LAN.
Chapter 2 HP NetServer AA Overview For information on the installation of the virtual network, see software installation procedures in the HP NetServer AA Solution Installation Guide.
Chapter 2 HP NetServer AA Overview Redirected Video and the CE Desktop Application In the server, CE video output is redirected to the IOPs. To accomplish this video redirection, the server uses several kernel mode drivers and the CE Desktop application, which is similar to industry-standard remote control applications. The CE Desktop application is a standard Windows NT GUI application.
Chapter 2 HP NetServer AA Overview HP NetServer AA Boot Process When the IOPs and CEs in a server are powered on, they automatically start a boot process that results in loading both Windows NT and the software. When powered on, the IOPs pass power-on self test (POST) and load the Windows NT operating system and the software. The IOP boot process must complete for the CEs to begin their boot process.
Chapter 2 HP NetServer AA Overview Figure 2-3 Overview of IOP Boot Process After the IOPs complete their boot process, the CEs boot: one CE loads the Windows NT operating system; then the other CE is synchronized so that both CEs perform all CPU and memory functions in a tightly coupled manner. This ensures that in the event of a CPU or memory failure, the server operating system provides continuous computing without any loss of context.
Chapter 2 HP NetServer AA Overview CEx CEy Powered on and completes POST Powered on and completes POST CE issues boot request. CE issues boot request. IOP services boot request. IOP servicing boot redirects its keyboard to the CE. CE loads Windows NT and Endurance software. CE has active control of all redirected devices. If IOPs are both present and their disks are not current, a mirror copy starts. CEs synchronize and start executing in lock step.
Chapter 2 HP NetServer AA Overview HP NetServer AA Characteristics During the CE Boot Process During the CE boot process, you can use Endurance Manager to view the state transitions of the server components. Server component state transitions are detailed in Table 2-1. Until the CE boot completes, the only redirected keyboard is the one attached to the IOP that is serving the boot request.
Chapter 2 HP NetServer AA Overview Table 2-1 Multi-Boot Options for IOPs Multi-Boot Option Description Operational Endurance I/ O Processor Mode This option is the normal operating mode for the IOP. This option boots a copy of Windows NT that contains and activates Windows NT and software. This is the only mode that allows an IOP to join the server. Offline Endurance I/O Processor Mode This option is for performing maintenance, such as upgrading the system configuration or system software.
Chapter 2 HP NetServer AA Overview HP NetServer AA Component States The server components can report any of the following states, depending on their status: • Server States • CE Operating System States • CE States • IOP States • Interconnect States • MIC Port State Display Lights • Mirrored Disk States • Network Connection States • Keyboard/Pointer States • Other HP NetServer AA Component States Note: You can use the Endurance Manager to view the current state of any component in the s
Chapter 2 HP NetServer AA Overview CE Operating System States The CE operating system states are: Table 2-3 CE Operating System States State Description Offline Indicates that the Windows NT operating system is neither running nor booting on any CE. Booting Indicates that the Windows NT operating system is in the process of being booted on a CE. Active Indicates that the Windows NT operating system is running on at least one CE.
Chapter 2 HP NetServer AA Overview Table 2-4 CE States State Description Faulted Indicates that the server removed the CE from operation as a result of one or more faults that were attributed to the CE. The CE remains in this state until it is repaired and an Endurance Manager CE Enable command is issued. Disabled Indicates that you issued an Endurance Manager CE Disable command that removed the CE from operation.
Chapter 2 HP NetServer AA Overview Table 2-5 IOP States (Continued) State Description Active Indicates that the IOP is a fully active member of the server configuration. In this state, the IOP serves I/O requests from any active CE(s) and participates fully in all fault handling events. The IOP remains in this state until it is shutdown, disabled, or removed from the configuration as the result of a system failure.
Chapter 2 HP NetServer AA Overview Table 2-6 Interconnect States State Description Active Indicates that the server components on both sides of the Interconnect are active members of the server configuration. The Interconnect remains in this state until one of the components is removed from the configuration. Then, the Interconnect transitions to offline or ready.
Chapter 2 HP NetServer AA Overview Table 2-7 MIC Port State Display Lights Color State Description Gray Unknown/ Unavailable This state occurs only on CE MIC ports. It indicates that, from the IOP’s perspective, no information about the state of this port has been received. Normally the CE MIC firmware relays the local port status to the IOP MICs. This does not occur, however, until the CE MICs are powered on and able to establish communication.
Chapter 2 HP NetServer AA Overview Table 2-8 Mirrored Disk States (Continued) State Description Faulted Indicates a disk failed a read or write request after repeated retries. The disk is not available for use by the CE operating system. You can use Endurance Manager to re-enable a disk that has experienced unrecovered failures and return it to service. You do not need to reboot the IOP to bring the disk back online. An ensuing mirror copy to the disk may correct bad spots present on the failed disk.
Chapter 2 HP NetServer AA Overview Network Connection States The network connection states are: Table 2-9 Network Connection States State Description Online Indicates that the Ethernet adapter and its associated network connection is active in the server configuration. The Endurance Manager Administration Window (Chapter 4) uses color to indicate whether the adapter is either primary or standby. • Primary indicates that the adapter is responsible for all transmits and receives.
Chapter 2 HP NetServer AA Overview Keyboard/Pointer States The keyboard and pointer states are: Table 2-10 Keyboard/Pointer States State Description Online Both the keyboard and pointer are available to the server. Faulted The keyboard or pointer is not available to the entire server configuration. In some cases (for example, failed keyboard or pointer), the input device is not available to either the IOP or CE.
Chapter 2 HP NetServer AA Overview Monitoring the HP NetServer AA Server Because the server is fault tolerant, when a fault occurs (for example, a failed disk), the server continues operating. However, even though it is operating, it may be vulnerable. This means that any failure to the faulted component’s redundant counterpart affects the availability of the server. Because of this, you need to monitor the status of the components in your server and correct any faults.
Chapter 2 HP NetServer AA Overview HP NetServer AA Messages When it is operational, software continuously monitors the server. It reports status and error messages by logging most messages in the Windows NT event log. Software displays some messages as they occur, either directly on the Windows NT blue screens during the text phase of boot or when a CE is being deconfigured; in pop-up windows; and for messages that pertain to the monitoring of the server, in a window on the Endurance Manager GUI.
Chapter 2 HP NetServer AA Overview Messages logged to the Windows NT System Event log use the standard Windows NT event format. (Refer to Windows NT documentation for the detailed information on Event Viewer fields and descriptions.) Messages are reported using the following icons and severity levels, described in Table 2-13. Table 2-13 Event Log Icons and Message Severity Levels Severity Level Informational Description Informational messages are the least severe and do not require action.

Chapter 3 Redirected Video and the CE Desktop Application Overview In the server, CE video output is redirected for display on the IOPs. To accomplish this redirection, the server uses several kernel mode drivers and the CE Desktop application, whose user interface is similar to industry-standard remote control applications. The CE Desktop application is a standard Windows NT GUI application. It runs on the IOPs and displays CE video output in a window on the IOPs.
Chapter 3 Redirected Video and the CE Desktop Application CE Video During Boot The CE Desktop application displays output from the CE that occurs after the CE passes POST and the text phase of the Windows NT boot process.
Chapter 3 Redirected Video and the CE Desktop Application Redirected Video Components This section describes the redirected video components used in the server. The kernel mode components of redirected video include software that runs on the IOP and on the CE. Software Running on the IOPs • MtcVidP.sys — the Video Provider • MtcVideo.exe — the CE Desktop application The Video Provider on each IOP communicates with the Video Redirector.
Chapter 3 Redirected Video and the CE Desktop Application In the IOPs, you should use any video cards that support resolutions of at least 1024 X 768 and also support more than 256 colors. The CE color palette is always set to 256 colors. You should run the IOPs at least one setting above 256 colors. Otherwise, the CE Desktop application will not display colors properly.
Chapter 3 Redirected Video and the CE Desktop Application Video Recommendations The following sections provide recommendations for the most efficient use of system resources. Some Remote Control Applications Not Supported on the CE The server does not support the use of remote control applications on the CEs that replace the video drivers with their own drivers. The video drivers are required for CE synchronization.
Chapter 3 Redirected Video and the CE Desktop Application Using the CE Desktop Application This section describes how to launch and use the CE Desktop application. Before you launch the CE Desktop application, set the color palette for the IOPs to a minimum of one setting above 256 colors. To set the number of colors: 1. From the Task Bar, select Start Settings Control Panel Display. 2. Select the Settings tab. 3. In the Color Palette box, select the number of colors from the list box.
Chapter 3 Redirected Video and the CE Desktop Application Running the CE Desktop Application The first time that you access the application, it runs in a window. After that, you can run the CE Desktop application either in a window or in full-screen mode.
Chapter 3 Redirected Video and the CE Desktop Application When the application is running in full-screen mode and you want to run the application in a window: 1. Change the input focus to the IOP. See Changing Input Focus on page 43. 2. Click the CE Desktop icon on the title bar. 3. Uncheck the Full Screen Mode option. If the CE is running at a lower resolution than the IOP, then the entire CE desktop can be resized so that it is visible without scroll bars.

The collection of all path components in a CE to IOP interconnect, including all MICs and MIC cables. IL. IOP Link. A private, dedicated Ethernet path between the IOPs.
Glossary MIC status lights. The lights on the MIC handles that indicate whether various MIC communications are functioning properly. minimum downtime upgrade. A hardware or software upgrade that requires the server to be shut down (typically for a few minutes) and rebooted. mirror set. The pair of physical SCSI disks (one on each IOP) that function as one logical disk. The disks in a mirror set process and maintain identical information.
Glossary redirected video. The CE graphical display that is displayed in a window on the IOPs. redirection. Identifies when a system uses a device that is not physically located in that system. For example, access to the Ethernet and SCSI devices is redirected from the CE to the IOP using Endurance software redirector. CE-based software driver that requests a specific service from a provider. redundancy.
