摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an embedded-system device. The embedded-system device obtains, through a first serial port, first input from a source and directed to a serial port. The embedded-system device attempts to detect in the first input a request for accessing the embedded-system device. The embedded-system device processes second input from the source received through the first serial port when the request is detected in the first input.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a service processor. The service processor loads a primary copy of a collection of environment variables from a storage device of the service processor. The service processor determines whether the primary copy is integral. The service processor, in response to a determination that the primary copy is not integral: loads a backup copy of the collection of environment variables from the storage device, determines whether the backup copy is integral, and boots an operating system with the collection of environment variables of the backup copy in response to a determination that the backup copy is integral.

摘要： Systems and methods for synchronizing a redundant array of independent disks (RAID) controller with a management controller. The system includes the management controller, a RAID having the RAID controller connected to the management controller; and a serial bus connected to the management controller and the RAID controller. The RAID controller is configured to, when the RAID is powered up, assert the serial bus with a ready signal, and the management controller is configured to, upon checking the ready signal from the serial bus, construct a communication with the RAID controller for communicating with the RAID.

摘要： Aspects of the disclosure relate to systems and methods of recording video frames from a computing device by a management device. The management device may receive video frames from the computing device. In response to receiving the video frames, the management device may process the video frames in a first-in-first out (FIFO) order to generate processed video frames according to a recording method, store the processed video frames in the FIFO order in the memory of the management device, and then release the memory occupied by some of the processed video frames in the FIFO order based on a memory releasing condition defined by the recording method to store the processed video frame. The memory releasing condition is determined by multiple optimized parameters of the recording method. The recording method may be a sliding window recording method, a multiple-window fixed size recording method, or a multiple-window dynamic size recording method.

摘要： Certain aspects of the disclosure relates to a system and method of performing virtual media redirection. The system includes a baseboard management controller (BMC) connected to a host computing device through a communication interface, and a client computing device communicatively connected to the BMC through a network. In operation, the BMC emulates a virtual media for a media device, and establishes a virtual media connection to the client computing device through the network. Then the BMC stores the data from the media device in a host cache at the BMC and in a client cache at the client computing device by sectors. When the BMC receives a request from the host computing device through the communication interface to retrieve sectors from the media device, the BMC redirects the sectors being requested to the host computing device depending on where the requested sectors are stored.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system may include a first embedded-system device and a second embedded-system device. The first embedded-system device receives a first message instructing the first embedded-system device to make configurations of the first embedded-system device available at a location in a network. The first embedded-system device makes the configurations available at the location. The second embedded-system device obtains a subset of the configurations made available at the location. The second embedded-system device restores itself with the subset of the configurations.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a service processor. The service processor receives a KVM console flow from a host. The service processor redirects the KVM console flow to a first destination console. The service processor redirects a video stream, without a keyboard stream and a mouse stream, of the KVM console flow to a second destination console. The service processor detects that the first destination console is disconnected from the service processor. The service processor invokes a privilege-checking event at the host.

摘要： Certain aspects direct to systems and methods for network switch management via a management controller using a management information base (MIB) to JavaScript Object Notation (JSON) parser. At a computing device, an administrator provides a MIB file corresponding to a network switch to be managed. Then the administrator utilizes a parser application to parse the MIB file at the computing device to retrieve Object Identifiers (OIDs) from the MIB file, and then converts the OIDs to JSON objects, in order to generate parsed information of the MIB file including the JSON objects. Thus, the administrator may use a browser to access a web user interface at a management controller to upload the parsed information of the MIB file to the management controller. The management controller may then manage and configure the network switch through a Simple Network Management Protocol (SNMP) interface based on the parsed information of the MIB file.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a management device. The apparatus may be a management device. The management device receives a first command. The management device determines whether the management device is in a protected mode for executing a protected process. The management device, in response to a determination that the management device is in the protected mode, determines whether the first command, when executed, interrupts the execution of the protected process. The management device, in response to a determination that the first command interrupts the execution of the protected process, discards the first command.

摘要： In one aspect, a system includes at least one virtualization server configured to executed a hypervisor, and a storage server in communication to the at least one virtualization server. The storage server stores a plurality of virtual machine (VM) operating systems (OS's). The storage server comprises computer executable code, including a VM scheduler service (VMSS) module. The VMSS module is configured to determine a scheduled start time for each of the VM OS's based on configuration data corresponding to the VM OS's, generate a command based on the scheduled start time for each of the VM OS's, and send the command to the at least one virtualization server. Upon receiving the command, the hypervisor executed at the at least one virtualization server requests data of one of the VM OS's at the corresponding scheduled start time to start the one of the VM OS's.
