WHEA "builds on the PCI Express Advanced Reporting to provide more detailed information about system errors and a common reporting structure." [4] WHEA allows third-party software to interact with the operating system and react to certain hardware events.
Serviceability or maintainability is the simplicity and speed with which a system can be repaired or maintained; if the time to repair a failed system increases, then availability will decrease. Serviceability includes various methods of easily diagnosing the system when problems arise. Early detection of faults can decrease or avoid system ...
The Problem Reports and Solutions Control Panel applet was replaced by the Maintenance section of the Action Center on Windows 7 and Server 2008 R2.. A new app, Problem Steps Recorder (PSR.exe), is available on all builds of Windows 7 and enables the collection of the actions performed by a user while encountering a crash so that testers and developers can reproduce the situation for analysis ...
This traditional form of interrupt signalling is an out-of-band form of control signalling since it uses a dedicated path to send such control information, separately from the main data path. MSI replaces those dedicated interrupt lines with in-band signalling, by exchanging special messages that indicate interrupts through the main data path.
Some motherboards have a built-in display to diagnose hardware problems. Most also report POST errors with audible beeps, if a PC speaker is attached. Such motherboards make POST cards less necessary. When these diagnostic cards were first introduced motherboards were expensive and well worth troubleshooting and repairing.
The IBM 4767 [1] PCIe Cryptographic Coprocessor is a hardware security module (HSM) [2] that includes a secure cryptoprocessor implemented on a high-security, tamper resistant, programmable PCIe board.
The PCI-X standard was developed jointly by IBM, HP, and Compaq and submitted for approval in 1998. It was an effort to codify proprietary server extensions to the PCI local bus to address several shortcomings in PCI, and increase performance of high bandwidth devices, such as Gigabit Ethernet, Fibre Channel, and Ultra3 SCSI cards, and allow processors to be interconnected in clusters.
Physical functions have the ability to move data in and out of the device while virtual functions are lightweight PCIe functions that support data flowing but also have a restricted set of configuration resources. The virtual or physical functions available to the hypervisor or guest operating system depend on the PCIe device. [3]
