management events can be viewed directly on the server or through HP Insight Manager, which can aggregate

information from multiple systems in the data center.

Customers also have the option to integrate fault management events with enterprise management software from

HP (OpenView) or from BMC, Tivoli, Computer Associates, or MicroMuse.

Added options with HP support

For customers who purchase HP support, fault management events can be forwarded to the HP support

organization. In this case, HP can take responsibility for monitoring, filtering, and trending the events and taking

action on items that need attention.

At the premium end of HP’s support offerings, customers can also sign up to receive services from HP’s High

Availability Observatory (HAO). The HAO provides continuous and proactive monitoring of the customer’s

environment via a dedicated and private ISDN network. The ISDN link allows secure information flow between the

customer site and HP’s support organization and provides HP support engineers with direct access to the

customer’s system. As part of the HAO implementation, HP installs a support node at the customer site, and this

node is connected securely to the HP support organization.

Proactive, not reactive

Fault management uses the philosophy of proactive (as opposed to reactive) management of problems. Fault

management provides highly accurate fault diagnosis the first time, even as the problem occurs, and initiates or

allows fast corrective action. Fault management results in a substantial decrease in unplanned downtime.

An easy transition for RISC and IA-32 users

A major feature of the Intel Itanium 2 processor and HP’s new servers is backward compatibility of the Intel

Itanium 2 processor with IA-32 and PA-RISC processors. Backward compatibility is particularly useful for

applications that are not performance-intensive or for system utilities and development tools that aid in porting and

migration. Although most existing IA-32 and PA-RISC binaries are compatible, optimal performance can only be

achieved once an application is compiled specifically for the Intel Itanium 2 processor.

Running 32-bit Windows applications

32-bit Microsoft Windows binaries can run on the 64-bit Windows operating system using the Intel Value Engine

(IVE) hardware and WOW64 software emulation, which is already part of 64-bit Microsoft Windows. The OS

automatically detects whether the application is 32-bit or 64-bit and handles it accordingly.

Additionally, Microsoft and Intel have now made available IA-32 Execution Layer (EL) software. The IA-32 EL is a

software binary that is available for download now from Microsoft; it will be integrated into Windows Server

2003 Service Pack 1. Whenever a 32-bit application is launched, the operating system will call the EL to translate

the 32-bit application into a native Itanium 2–based application. The EL, working in conjunction with an Intel

Itanium 2 processor, is expected to yield application performance similar to that of a 1.5 GHz Intel Xeon™

Processor MP. Because EL compatibility is gained via software translation, the EL will deliver further performance

improvements on faster Intel Itanium processors released in the future. The EL is expected to supersede the Intel

Value Engine hardware feature because it will clearly provide much better performance on 32-bit applications.

Running 32-bit Linux applications

32-bit Linux binaries can be run on Itanium 2–based systems using the processor’s built-in hardware translation

feature. The Intel Value Engine hardware is part of the Intel Itanium 2 processor, and it gives a basic IA-32

functionality. If an application is performance-critical, recompiling the application will allow it to take advantage

of the strengths of the Intel Itanium 2 microarchitecture.

The IA-32 Execution Layer

Beginning in the second half of 2003, 32-bit software compatibility will be enhanced via the Intel IA-32 Execution

Layer (IEL). IEL is a software binary that will be integrated into major Itanium 2–based operating system releases.

Whenever a 32-bit Intel application is launched, the operating system will call the IEL to translate the 32-bit

application into a native Itanium 2–based application. IEL, working in conjunction with an Intel Itanium 2

processor, is expected to yield application performance similar to that of a 1.5 GHz Intel Xeon Processor MP.

Because IEL compatibility is gained via software translation, the IEL will deliver further performance improvements
