Abstract: A noise reduction door related to a noise reduction device in order to resolve a problem that the noise reduction door cannot meet a requirement for different noise reduction effects and different air duct resistance. The noise reduction door includes a T-shaped mechanical part, two fan-shaped mechanical parts, and a door plate. The T-shaped mechanical part and the fan-shaped mechanical part are connected to the door plate using a detachable connection mechanical part. The T-shaped mechanical part is located on a central axis of the door plate, and the two fan-shaped mechanical parts are respectively located on two sides of the T-shaped mechanical part. Therefore, the fan-shaped mechanical part on the door plate may be changed to have different installation positions and installation manners in order to obtain noise reduction doors in different forms. The embodiments of the present disclosure are applied in cabinet noise reduction.

Abstract: A redundancy method includes that a first disaster management function (DMF) device on a first site side receives a first request including identification information of a first virtual machine (VM) and a recovery point objective (RPO), allocates a maximum allowable delay time to each node that input/output (IO) data of the first VM passes through in a redundancy process, and sends a second request to a second DMF device on a second site side. The second request includes a maximum allowable delay time of a second replication gateway function (RGF) device on the second site side, and a maximum allowable delay time of an IO writer function (IOWF) device on the second site side and requests the second site side to perform redundancy on the first VM. Hence, the RPO requirements of the tenants can be satisfied in an entire redundancy process.

Abstract: A virtual machine creation method and apparatus are provided to automatically create a virtual machine, and avoid an error that occurs during creation of the virtual machine. The method includes obtaining, by a cloud management platform at a production site, a first redundancy policy, obtaining, by the cloud management platform, storage replication information from M storage devices at the production site, determining, by the cloud management platform based on the storage replication information and from the M storage devices, N storage devices that meet the first redundancy policy, where N is an integer, and N≤M, controlling, by the cloud management platform, a virtualization platform to create a virtual machine, and instructing, in a virtual machine creation request, to create a magnetic disk used by the virtual machine on the N storage devices to create the virtual machine.

Abstract: A redundancy method includes that a first disaster management function (DMF) device on a first site side receives a first request including identification information of a first virtual machine (VM) and a recovery point objective (RPO), allocates a maximum allowable delay time to each node that input/output (TO) data of the first VM passes through in a redundancy process, and sends a second request to a second DMF device on a second site side. The second request includes a maximum allowable delay time of a second replication gateway function (RGF) device on the second site side, and a maximum allowable delay time of an IO writer function (IOWF) device on the second site side and requests the second site side to perform redundancy on the first VM. Hence, the RPO requirements of the tenants can be satisfied in an entire redundancy process.
