    Abstract: A first storage node is connected to a host by using a first network interface card of the first storage node, and is connected to a second storage node by using a second network interface card. The first storage node receives a data processing request from the host, wherein the data processing request carries a target storage address of to-be-processed data, determines the second storage node based on the target storage address of the to-be-processed data, and sends the data processing request to the second storage node by using the second network interface card, wherein the data processing request instructs the second storage node to process the to-be-processed data.

    Abstract: A method for adjusting over provisioning space and a flash device are provided. The flash device includes user storage space for storing user data and over provisioning space for garbage collection within the flash device. The flash device receives an operation instruction, and then performs an operation on user data stored in the user storage space according to the operation instruction. Further, the flash device identifies a changed size of user data after performing the operation. Based on the changed size of data, a target adjustment parameter is identified. Further, the flash device adjusts the capacity of the over provisioning space according to the target adjustment parameter. According to the method, the over provisioning ratio can be dynamically adjusted.

    Abstract: Embodiments of the present invention provide a bandwidth adjustment method, a bus controller, and a signal convertor. The method includes: obtaining, by a bus controller, a first frequency and a first channel number; sending a bandwidth negotiation request carrying the first frequency and the first channel number to a bus controller of a first peer end to determine whether or not the bus controller of the first peer end is capable of controlling a physical component of the first peer end to receive data via a channel corresponding to the first channel number according to the first frequency; and receiving a negotiation result sent by the first peer end and controlling the physical component to transmit data according to the negotiation result. In the technical solutions of the embodiments of the present invention, bandwidth adjustment is flexible and the loss of data is avoided.
