Abstract: A system of controlling a vehicle may include a sensor and a controller, in which the sensor may be configured to sense vehicle operation state information, and the controller may be configured to determine whether a vehicle is running on a dangerous road based on the sensed vehicle operation state information, determine whether there is a possibility that a vehicle driving state will cause a failure of a driving system based on the sensed vehicle operation state information in response to determining that the vehicle is running on the dangerous road, and decide that torque control of the vehicle.

Abstract: A hard disk snapshot method and apparatus based on Openstack platform. The method includes: initiating a cloud hard disk creation request based on a snapshot, and determining, on the basis of a type of a new cloud hard disk, a second storage backend that is about to accommodate the new cloud hard disk (S101); in response to the second storage backend being different from a first storage backend where an old cloud hard disk that stores the snapshot is located, and mounting the old cloud hard disk on one host machine (S103); creating the new cloud hard disk on the second storage backend on the basis of the type of the new cloud hard disk, and mounting the new cloud hard disk on the host machine (S105); and replicating the snapshot from the old cloud hard disk to the new cloud hard disk through the host machine (S107).

Abstract: A method and apparatus for preparing an image on a cloud platform, and a device and a storage medium are provided. The method may include: receiving an image request for a target object, and obtaining a first storage backend of the target object according to the image request (S100); obtaining a second storage backend of a Glance service in the cloud platform, and comparing the second storage backend with the first storage backend (S200); and obtaining an image for the target object on the second storage backend in a cloning manner when the first storage backend is the same as the second storage backend (S300). According to the method, the first storage backend of the target object is obtained according to the received image request, and the second storage backend of the Glance service in the cloud platform is obtained.

Abstract: Provided is a method for auditing an abnormality of a block device in a cloud platform. By automatically auditing abnormal data of a path layer and a multipath layer, the accuracy of multipath and path information on a host and whether a link has a fault may be quickly analyzed, operation and maintenance personnel may discover problems as soon as possible, the problem troubleshooting steps are simplified, the operation and maintenance personnel are liberated from complex work of manual troubleshooting, the troubleshooting capability of a cloud computing platform is improved, the work of the operation and maintenance personnel is simplified, and the problems are rapidly positioned.

Abstract: Disclosed is a file storage management method. The method includes the following steps: sending a mount request to a management platform by using an agent service, and receiving a mount parameter returned by the management platform; recording the mount parameter into a configuration file of the agent service; determining, according to the configuration file, the address of a file storage to be mounted; and mounting a file system in response to a normal heartbeat between an address of a cloud host and the address of the file storage to be mounted. Further disclosed are a system, a computer device, and a readable storage medium.

Abstract: Provided is a method for auditing an abnormality of a block device in a cloud platform.

Abstract: A heat exchanging device includes: an inner wall and an outer wall, wherein the inner wall is close to the center axis of the heat exchanging device. The inner wall and the outer wall together form a chamber for a cooling medium to flow. The inner wall is provided with at least one protrusion component having an internal cavity. The protruding direction of the protrusion component faces the center axis. The internal cavity of the protrusion component is in communication with the chamber formed by the inner wall and the outer wall. The protruding direction of the protrusion component faces the crystal bar, and the internal cavity of the protrusion component is in communication with the chamber formed by the inner wall and the outer wall, which increases the heat exchanging area, and reduces the horizontal distance between the cooling medium and the crystal bar.

Abstract: A mold, comprising: a substrate, the substrate having an inside surface and an outside surface; and a ceramic coating formed on at least substantially the entire inside surface, the ceramic coating comprising chromic oxide, silicon dioxide, and alumina. A method for making the present mold is provided.
