摘要:
Embedded controller(s) in an information handling system have real-time status and activities represented by indicators, such as light emitting diodes (LEDs), associated with the embedded controller(s). These indicators may be monitored for example by operating (management software, e.g., Embedded Server Management (ESM) software. In addition, edge triggered latches and a timer detect and store flash patterns of these LED indicators so that the flash pattern information may be read by the operating management software as static signals.

An information handling system includes first and second I/O controllers, a detector for detecting an I/O controller failure, and an I/O recovery unit. The first I/O controller adaptively controls a first and a second I/O slot. The second I/O controller adaptively controls a third and a fourth I/O slot. Lastly, the I/O recovery unit, responsive to a detected I/O controller failure, operatively couples/decouples the first and second I/O slot to/from the first I/O controller, operatively couples/decouples the third and fourth I/O slot to/from the second I/O controller, and operatively decouples/couples the first and second I/O slot from/to the third and fourth I/O slot according to an I/O failure recovery protocol, the I/O failure recovery protocol provided for adapting one of either the first and second I/O controllers to operatively couple to the first, second, third and fourth I/O slots as a function of the detected I/O controller failure.

A method and system for storing and updating RAID configuration information in a storage site separate from both the RAID controller and RAID disk drives is disclosed. The configuration information in the storage sites are compared and the configuration of the RAID system is automatically without user intervention. The method may be used in any computer or information handling system.

An information handling system comprises a power supply unit providing a controllable main power supply and a stand-by power supply, a power controller unit receiving the stand-by power supply, and a plurality of sub-systems. Each sub-system comprises a voltage regulator unit being controlled by the power controller unit.

摘要:
A method and circuitry for reconfiguring the links of a PCI Express bus after a user hot swaps a PCI device. A computer system has been initially configured with PCI Express bus links to various endpoints, using the scaling features of the PCI Express standard. If a hot swap occurs, an SMI routine is used to signal a reconfiguration circuit to reroute unused links (or unused portions of links) to one or more other PCI devices.

A system and method for updating the firmware of storage drive in a drive array is disclosed. The method includes the steps of updating the firmware of a spare drive. The spare drive is swapped for a drive of the drive array having unupdated firmware. The content of the spare drive is built on the basis of the content of the other storage drives of the storage arrays and according to the data recovery scheme of the drive array. The firmware of the selected storage array is updated and the updated storage drive is swapped with the spare storage drive in the drive array. The content of the updated storage array is then rebuilt or restored.

A server cluster comprises a physical node and a virtual host node. The physical node includes an active node running an application. The virtual host node includes an inactive virtual node. The virtual node is activated upon failure of the active node and the application is failed over to the virtual node.
