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.

On-demand provisioning of computer resources in physical/virtual cluster environments

A method and systems for recovering from a failure in a virtual machine are provided. In accordance with one embodiment of the present disclosure, a method for recovering from failures in a virtual machine is provided. The method may include, in a first physical host having a host operating system and a virtual machine running on the host operating system, monitoring one or more parameters associated with a program running on the virtual machine, each parameter having a predetermined acceptable range. The method may further include determining if the one or more parameters are within their respective predetermined acceptable ranges. In response to determining that the one or more parameters associated with the program running on the virtual machine are not within their respective predetermined acceptable ranges, a management module may cause the application running on the virtual machine to be restarted.

A modular fiber channel information handling system includes a storage processor and multiple associated fiber channel data storage enclosures. The storage processor and the fiber channel data storage enclosures are connected by a fiber channel storage loop. The storage processor includes an identification engine operable to assign device addresses to the associated storage devices and an aggregation engine that is able to selectively aggregate the shelf IDs of data storage enclosures that have been selected to be aggregated.

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.

An information handling system includes first and second input/output (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.

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 system and method for replicating data in a computer system is disclosed. In one embodiment, data replication between a source subsystem and a target subsystem may be selectively changed between synchronous data transfer and asynchronous data transfer based on the occurrence of selected conditions. In another embodiment, a repository subsystem allows write statements to be queued during the time that the target subsystem is unable to replicate data from the source subsystem.

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.
