摘要： The technology of this application relates to a network interface card. The network interface card includes a parser and at least one shared connector. The parser receives a first SEND message that is from a host client and that corresponds to a first QP connection, and distributes the first SEND message to a first shared connector in the at least one shared connector. The first SEND message includes an RDMA operation command. The first shared connector obtains NVME information that is sent to a first controller and that corresponds to the first QP connection. The first shared connector interacts with a second controller when a disconnection event of a link between the first shared connector and the first controller is detected. The first shared connector obtains a WQE from the second controller. The first shared connector sends a first RDMA message corresponding to the first QP connection to the host client based on the WQE.

摘要： A method for implementing storage service continuity in a storage system includes a front-end interface detecting a status of a first storage controller. The storage system includes the front-end interface card and a plurality of storage controllers. The front-end interface card communicates with the storage controllers, and the front-end interface card communicates with a host. When the first storage controller is in an abnormal state, the front-end interface card selects a second storage controller from the storage controllers for the host to process an access request of the host.

摘要： A just a bunch of flash solid-state drive cluster (JBOF) and a method for transmitting a data processing request include obtaining a data processing request sent by a storage controller, determining a type of the data processing request, and either forwarding the data processing request to the target solid state drive (SSD) when the type of the data processing request is a bypass type, or sending the data processing request to a computing unit in the JBOF and sending the data processing request processed by the computing unit to the target SSD when the type of the data processing request is a background computing type.
