A client-server network environment is temporarily transformed into a grid computing environment through the deployment of a network-booted grid operating system to each of a plurality of network clients. Each participating client operates in the client-server mode under a local operating system. At an appropriate time, a server transmits to each client a thin-client boot image (a dynamically built customized image or an image obtained from a store of predefined boot images) along with a grid application for which the thin-client has been optimized for peak performance. Each client re-boots using the thin-client image, thereby entering the grid mode and executing the grid application.

Redistribution of operating environments for the redeployment of grid clients

A client-server network environment is temporarily transformed into a grid computing environment through the deployment of a network-booted grid operating system to each of a plurality of network clients. Each participating client operates in the client-server mode under a local operating system. At an appropriate time, a server transmits to each client a thin-client boot image (a dynamically built customized image or an image obtained from a store of predefined boot images) along with a grid application for which the thin-client has been optimized for peak performance. Each client re-boots using the thin-client image, thereby entering the grid mode and allowing substantially all of its computing resources to be dedicated to executing the grid application. At a later time, the server directs that each client terminate the grid application and re-boot in its respective local operating system, reverting again to the client-server mode.

An apparatus, system, and method are disclosed for non-interruptively updating firmware on a redundant hardware controller. The apparatus includes a routing module, a receiving module, and a forwarding module. The routing module routes communications between a redundant hardware controller and a service processor associated with a flash update. The receiving module receives a flash command for the flash update from the service processor via a shared serial connection. The forwarding module forwards the flash command via a dedicated point to point connection to the redundant hardware controller configured to receive the flash command over the point to point connection. The apparatus, system, and method provide a non-interruptive overlay of the firmware image on a redundant hardware controller, minimizing system downtime and user intervention.

Provided are a techniques for processing a download. Under control of a first target device, a download command is received via a first communication medium that indicates that an update is to be downloaded. The download command is issued to a second target device via a second communication medium, wherein the second communication medium is a private device communication medium that enables private communication between the first target device and the second target device. The update is received via the first communication medium. In response to determining that the update has been downloaded, run with the update.

Simultaneous download to multiple targets

An apparatus, system, and method are disclosed for receiving digital instructions at devices or controllers sharing an identity. A first controller receives a digital instruction instance over a communications medium. The digital instruction instance may be a firmware instance. The first controller has ownership of the communications medium and shares the communications medium and a common identity with a second controller. An ownership module transfers ownership of the communications medium from the first controller to the second controller. The ownership module may transfer ownership in response to the first controller successfully receiving the digital instruction instance. A request module requests a retransmission of the digital instruction instance, and may request the retransmission in response to the transfer of ownership of the communications medium. The second controller receives the retransmitted digital instruction instance in response to the retransmission request.

An apparatus, system, and method are disclosed for updating firmware to a plurality of memory devices residing on disparate controllers wherein each controller includes an identical communication path address. A management module writes a firmware image to a memory device residing on a primary controller. The primary controller, in turn, copies the firmware image to another memory device residing on a secondary controller. In this manner, the apparatus, system, and method may update firmware on a plurality of memory devices. Because the primary controller is tasked with updating the secondary controller, the management module is only aware that the firmware of the primary controller has been updated. In this manner, updating of the firmware on the secondary controller is transparent to the management module.

Apparatus, system, and method for firmware update of redundant controllers

An apparatus, system, and method are disclosed for accessing redundant data. A verification value module calculates a first verification value for a first redundant memory. In addition, the verification value module calculates a second verification value for a second redundant memory. In one embodiment, a validation module validates the first and second verification values. A selection module accesses the first redundant memory if the first verification value is equivalent to the second verification value. In a certain embodiment, the selection module identifies and accesses the redundant memory with a most advanced generation count if the first and second verification values are valid and are not equivalent.
