Abstract: An acceleration resource scheduling method includes: receiving an acceleration instruction sent by the virtual machine, where the acceleration instruction includes to-be-accelerated data; determining a virtual accelerator allocated to the virtual machine; determining, based on the virtual accelerator, a network accelerator that is to process the acceleration instruction, and sending the acceleration instruction to the network accelerator, so that the network accelerator sends the acceleration instruction to a physical accelerator that is to process the acceleration instruction; receiving a computing result that is returned after the physical accelerator performs acceleration computing on the to-be-accelerated data by using the physical acceleration resource; and sending the computing result to the virtual machine.

Abstract: A fault isolation method, computer system, and apparatus, which are capable of monitoring a state of a second endpoint device in the extended domain, and setting a device state record according to the state of the second endpoint device; after an access request between the second endpoint device and the primary domain is received, querying the device state record according to identifier information that is of the second endpoint device and in the access request, and determining the state of the second endpoint device; and if the state of the second endpoint device is a fault state, discarding the access request to prevent communication between the faulty second endpoint device and the primary domain and prevent spreading a fault to the primary domain, thereby ensuring system reliability.

Abstract: A power consumption management method and a related device are provided. The method may be used to manage power consumption of a device including a plurality of voltage domains, where each of the voltage domains includes at least one processor core. The method includes: during power consumption management, identifying a first voltage domain that meets a preset condition in a plurality of voltage domains, migrating tasks to be executed by all processor cores in the first voltage domain to a second voltage domain, and then setting each of working modes of components in the first voltage domain as a first mode.

Abstract: The present invention provides a data write method and a solid-state drive array. The solid-state drive array is based on a RAID system and includes n solid-state drives. Before to-be-written data is written into the solid-state drive array, the to-be-written data is divided into n data blocks that are in a one-to-one correspondence with the n solid-state drives. After the n data blocks are all stored into the corresponding solid-state drives, FTL update of the n data blocks is performed, to complete write of the to-be-written data. If the solid-state drive array is powered off during storage of the n data blocks, because FTL update of the data blocks is not performed, all the n data blocks fail to be written into the solid-state drive array, thereby ensuring atomicity of write operations of the n data blocks.

Abstract: In a transmission rate determining method, a proximity coupling device (PCD) sends an activation frame to a proximity integrated circuit card (PICC). The activation frame indicates at least a first transmission rate used to transmit a first information frame and a second transmission rate used to transmit a target frame. The first information frame is used to transmit application information. The target frame includes at least one of a second information frame or a third information frame, the second information frame is used to transmit receive ready information, and the third information frame is used to transmit control information. The PCD receives an acknowledgment frame from the PICC. The acknowledgment frame indicates that the PICC has received the activation frame. Then, the PCD transmits the first information frame with the PICC at the first transmission rate, and transmits the target frame with the PICC at the second transmission rate.

Abstract: A bare-metal server of a cloud storage management system comprises a system-on-chip (Soc) and a processor. The SoC receives a volume attaching request sent by a public cloud management component of the management system. The volume attaching request includes an identifier of a system volume storing a file for starting an operating system of a bare-metal server of the management system. The SoC stores the identifier of the system volume based on the volume attaching request. When the bare-metal server of the management system is started, the bare-metal server uses the identifier of the system volume to the system volume, and starts an operating system by means of the SoC accessing the system volume.

Abstract: A data forwarding chip and a server are disclosed. The server includes a data forwarding chip, a network interface card, and a processor. The data forwarding chip is separately connected to the network interface card and the processor through a bus. After receiving a data forwarding request sent by the processor or the network interface card, the data forwarding chip forwards, based on a destination address of the data forwarding request through an endpoint port that is on the forwarding chip and that is directly connected to a memory space corresponding to the destination address of the data forwarding request, to-be-forwarded data specified in the data forwarding request, such that when the server sends or receives data, cross-chip transmission of data between processors occurs, thereby reducing a data transmission delay.
