Abstract: Logging into a remote computer by way of a management processor to initiate a remote console session and switching between a default remote console session and a non-default remote console session.

Abstract: Systems, methodologies, and media associated with acquiring a graphics mode post-failure screen provided by a graphical operating system running on a self-reset capable computer are described. One exemplary method embodiment may be performable in a management processor (e.g., ASIC, FPGA) that is configured to be operably connected to a computer (e.g., server) that is configured to provide a graphical post-failure screen and to self-reset upon entering a failure state. The exemplary method embodiment may include receiving a stream of video data from the computer and making it available to a downstream component like a remote console application. The exemplary method may also include performing a screen refresh after detecting the failure state in the computer. The exemplary method may also include selectively storing the graphical post-failure screen in a memory associated with the management processor.

Abstract: A remote management controller may include a video redirection device and a processor. The video redirection device may be configured to: obtain a slice of video data output from a video graphics controller; calculate at least one value correlative to the slice of video data; and if the calculated value for any portion of the slice differs from a value for a previously obtained corresponding portion, update a table associated with an image related to a remote system with the calculated value, and process the portion of the slice to create a data portion of a network packet in a network buffer. The processor may be configured to: allocate the network buffer; and provide a header portion of the network packet to the network buffer.

Abstract: Methods, devices, and systems for multiple host management are provided. An example of a method for multiple host management includes a multiple host management device managing a plurality of host instances. The multiple host management device can provide each of the plurality of host instances with a plurality of input/output (I/O) functionalities.

Abstract: A system comprising a first computer and a second computer remotely located from the first computer and in communication with the first computer via a network. The second computer comprises an encoder module which encodes and transmits a pixel color datum to the first computer. The encoder module encodes the pixel color datum by generating a bit indicative of the number of different pixel color data encoded since a datum having a same color as the pixel color datum was last encoded.

Abstract: A remote management controller may include a capture engine and a processor. The capture engine may be configured to obtain a slice of video data output from a video graphics controller, store the slice of video data, and calculate at least one value correlative to the slice of video data. The processor may be configured to retrieve the slice of video data stored by the capture engine and process any changed portion of the slice of video data for transmission to a remote system.

Abstract: A remote management controller may include a video redirection device and a processor. The video redirection device may be configured to: obtain multiple separate slices of video data output from a video graphics controller; calculate at least one value correlative to each of the multiple separate slices of video data; and if the calculated value for any portion of any of the multiple separate slices differs from a value for a previously obtained corresponding portion, update a table associated with an image related to a remote system with the calculated value, process the portion of the slice into a network packet, and move the network packet to one of multiple network buffers. The processor may be configured to: allocate the multiple network buffers; and facilitate transmission of the network packets loaded into the network buffers to the remote system.

Abstract: A remote management controller may include a capture engine and a processor. The capture engine may be configured to: obtain a slice of video data output from a video graphics controller; calculate at least one value correlative to the slice of video data; determine whether any portion of the slice has been locked; and if any portion has not been locked and if the calculated value for such portion of the slice differs from a value for a previously obtained corresponding portion, move the portion to a virtual screen buffer, update a table associated with the virtual screen buffer with the calculated value, and modify a change table to indicate that the portion has changed.

Abstract: A method and apparatus captures the color palettes of a video graphics controller of a managed computer to a remote computer to transmit correct color information to a remote computer. A remote management controller may perform this technique independent from the operating system. The managed computer includes a processor and a video graphics controller. The remote management controller snoops a bus, which couples the processor to the video graphics controller, for processor accesses to the EGA and VGA color palettes stored in the video graphics controller. The remote management controller includes an EGA shadow look up table and a VGA shadow look up table that store the snooped information which is used to create correct color information to be transmitted to the remote computer so that it can display the same colors generated at the managed computer.
