Abstract: A method for deploying bare computers implemented in an electronic device includes starting at least one bare computer to be deployed, and assigning an IP address to the at least one bare computer; downloading a deployment image to the at least one bare computer based on the IP address, and obtaining hardware information of the at least one bare computer based on the deployment image; determining at least one service to be provided by the bare computer according to a preset deployment strategy and the obtained hardware information of the bare computer; and generating a system image according to the at least one service to be provided by the bare computer, and deploying the system image in the bare computer.

Abstract: A method for implementing high availability of bare metal node based on OpenStack utilizes a control node communicating through a power control network with a main bare metal node and a backup bare metal node. The control node turns on a power supply to activate an operating system image file installed in the main bare metal node. Information as to status is sent to the control node by the main bare metal node, and if the status information ceases, the control node, switches off the power supply to the main bare metal node. The control node turns on a power supply to the backup bare metal node to activate the operating system image file therein and selects as subsequent backup a further bare metal node and installs activate the operating system image file therein.

Abstract: A magnetic scanning method includes acquiring an image from a storage device of a magnetic scanning device, controlling a magnetic read-write head of the magnetic scanning device to touch a reference point on a plane, generating an electric signal which reflects relevant information of the acquired image, inputting the electric signal reflecting the relevant information of the acquired image to the magnetic read-write head, when the electric signal reflecting the relevant information of the acquired image flows through the magnetic read-write head, controlling the magnetic read-write head to generate a magnetic field corresponding to the electric signal, controlling the magnetic read-write head to move and scan the plane from the reference point, to magnetize the magnetic powder on the plane by the magnetic field, and driving the magnetic powder to move relatively to generate an image similar to the acquired image.
