HP’s NetServer AA server is a fault tolerant Microsoft Windows NT server that provides

Constant Computing 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.

The server provides contin uous computin g for your Windows N T server and its ap plications by providing redundant CPU processing and memory. It ensures data redundancy by mirroring server data across i ndependen t s torage sy stems.

The server detects events and reports any events, including state changes and faults, to the Windows NT event logs or displays them as they occur on Windows NT blu e screens during the text phase of boot or when a CE is being deconfigured. Events are also reported in pop-up windows; and, for messages that pertain to the monitoring of the server, events can be displayed in windows on the Endurance Manager. Using third-party alarm notification tools, you can configure the server to notify you when targeted events occur.

The server includes the Endurance Manager, a complete server management solution. The Endurance Manager is a graphical user interface (GUI) based management tool that enables you to monitor and manage the s erver. This tool includes both local and remote manageme nt support for the server.

The key benefits of using the server are listed in Table 1-1.

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.

To achieve full redundancy and fault tolerance, the server integrates four industry-standard Pentium-based systems with HP’s hardware and software. As a result, the Windows NT operating system and all network services and applications perceive the server as a single system, as shown in Figure 1-2.

HP NetServer AA Server Hardware Configuration

With four systems integrated into a single Windows NT fault tolerant server, as shown in

Figure 1-1, the server provides complete hardware redundancy. Because the server uses

redundant hardware, its hardware availability far surpasses that of a standard Windows NT server. Using redundant hardware also allows online service and replacement of h ardware. The server supports multiple network connections to provide additional network redundancy and network traffic control.

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 Pr ocessors) contain the keyboard and mouse, mirrored SCSI devices, redundant network adapters, and other I/O devices. Because there are two IOPs, the mirrored SCSI devices (one on each IOP) provide fault tolerant data storage, and the redundant network adapters (one on each IOP) provide redundant network connectivity. The IOPs handle all server I/O requests.

The server uses MICs and the ILs to interconnect four standard systems into the server configuration. This enables these systems to function as one server:

• MIC (Marathon Interface Card) is an adapter that provides a high speed interconnect path for the server. There are four MICs in a server: one in each IOP, and one in each CE.

• IL (IOP Link) cable connects IOP1 and IOP2.

By using redundant hardw are, HP is also able to implement SplitS ite technology in your server. SplitSite enables you to locate each tuple of a server residing in different locations. This provides a method of offsite data protection while also providing protection from potential site disasters.

Chapter 1 Introduction

Endurance Software

Endurance software integrates and synchronizes processing across four industry-standard Pentium class systems. All components are capab le of multiprocessing, forming a log ical, fully redundant, fault tolerant server. This results in the Windows NT operating sys tem , all applications, and the local area network log ically perceiving the integrated systems in the server as a standard Windows NT server. Endurance server software provides fault tolerant functionality, including:

• Redundant processing environment. Using redundant CEs and memory, the software

performs CPU and memory functions in a tightly coupled manner. In the event of a CPU or memory failure, the operating system remains continuously available, providing constant computing without any loss of context.

• Redundant I/O subsystem. The software redirects I/O requests from the CE to the IOPs.

The software coordinates all I/O requests, as follows:

- Because all I/O devices in the server physically reside on the IOPs, Software redirects all I/O requests from the CEs to the IOPs. As a result, these I/O devices are logically associated with the CE. For example, the software can redirect a CD-ROM drive physically located in an IOP so that it is logically assigned to the C E (the CE has complete control of that CD-ROM drive).

- For mirrored disk devices and redundant Ethernet connections, the software coordinates all I/O processing so that these redundant components appear as a single logical device. For example, in a mirrored disk set, the two physical disks (one on each IOP) appear to the CE operating system and applications as on e logical disk. If a disk failure occurs, the disk operations can transparently continue operating without affecting any server applications or clients.

• Automatic fault detection and reporting. The software continuously monitors the server. If the software detects a fault, the server isolates the fault and deconfigures any affected components. When a fault occurs, software ensures that the server remains operational by automatically using the redundant components. The fault detection and reporting process occurs seamlessly, and in a fully operational server, it maintains complete server availability. The software reports all events, including general status, state changes, and faults, to the Windows NT event log or displays them in windows as they occur.

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 ph ysical networ k adapter or co nnectivity failures. If a failure occurs, the redundant adapter automatically controls the flow of all network traffic.

• Transparent reconfigur at i on. After a faulted component is returned to service, the server automatically reconfigures any required components. For example, when a failed CE is returned to service, that CE is automatically resynchronized so that it is identical to the CE that is already in operation. Likewise, when a failed mirrored d isk is retur ned to service, a mirror copy automatically occurs so that the data on both mirrored disks is identical.

• Server management. The software includes Endurance Manager, a complete management tool for your server. Endurance Manager is a standard Windows NT application that enables you to monitor, configure, and manage the server. You can run Endurance Manager locally (at an IOP or a CE) or from a remote Windows NT server. For a detailed description of Endurance Manager and its features, refer to Chapter 4.

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 serv er using Endurance Manager, a GUI-based manag ement 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.

• Issue commands to manage the server and its components, including enabling and disabling components.

• Access statistics about the server, including Ethernet counters.

• Determine the status of the server’s mirrored disks, incl uding t he direction of any pend ing

mirror copies, and if a mirror copy is in progress, the percentage of completion.

• Access the Endurance Configuration Utility and Windows NT administration tools.

• View certain messages that display as they occur in a window on the GUI. Messages

displayed on the GUI pertain only to the monitoring of the server; messages related to changes in the state of the server do not display on the GUI.

• Administer your server from a remote workstation using either a local area network connection or Microsoft’s Remote Access Server (RAS).

Note: You can also install the online manuals on a remote wor kstation.

For detailed information about the Endurance Manager, refer to Chap ter 4. A fully operational s erver uses four l icensed copies of the Windows NT oper ating system. Refer

to HP NetS erver AA 6200 Solution Relea se Notes (Release 3.0 Service Pack 1) for details about the versions of Windows NT that are supported by t his release of the software. Th e requirements for copies of the Windows NT operating system follow.

• Each CE requires a separate licensed copy of the Windows NT operating system. The CE operating system offers access to redirected I/O devices, including mirrored (redundant) disks. As a result, you need to use the CE operating system to run all server applications and to perform all Windows NT administrative tasks.

• Each IOP requires a separate licensed copy of the Windows NT operating system that should be accessed only to perform maintenance procedures.

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.

- ESI21 is the path from IOP2 to CE1.

- ESI22 is the path from IOP2 to CE2.

• The IL (IOP Link) is a dedicated private network for completing mirror copies

(transferring mirrored disk data) between the IOPs, and for communication between the IOPs. The IL is physically supported by connecting two Ethernet adapters, one in each IOP.

The ESI is the I/O data path between the CE and redirected devices on the IOPs.

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 Ne twork

Each IOP to CE virtual network is a separate LAN. There is no direct virtual LAN b etween the two IOPs. (To have this capability , HP recommends th at you install En hanced IL networ king.) The virtual network requires no additional hardware.

Benefits of the virtual network include:

• IOP access to CE disks while online

• IOP access to redirected floppy drives and CD-ROMs

• CE access to IOP event logs, memory dumps, and other files

The virtual network includes the following components:

• Virtual Net work Redirector (VNR)

• Virtual Netw ork Provider (VNP)

Network transports are bound to VNR and VNP just as they would be bound to any standard Network Interface Card. Ethernet addresses for all virtual adapters are automatically assigned and are based on the Ethernet Vendor ID.
