Embodiment Construction

[0054] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0055] First, combine Figure 1 to Figure 3 Introduce the traditional data processing method.

[0056] figure 1 is a schematic diagram of a computing device. Such as figure 1 As shown, computing device 10 includes RNIC101, processor 102 and SCM103, RNIC, processor 102 and SCM103 are connected by bus 104, wherein, bus 104 includes but not limited to peripheral bus (such as peripheral device interconnection (peripheral component interconnect, PCI) bus, PCIe bus, etc.), a system bus; the processor may be a central processing unit (central processing unit, CPU). The processor includes 102 including an integrated input / output controller (integrated input / output, IIO), a last level cache (last level cache, LLC), an integrated memory controller (integrated memory controller, iMC) and one or more proces...

Abstract

The invention provides a data processing method, an RNIC and equipment, and the method comprises the steps that a first RNIC receives an RDMA write request sent by a second RNIC, the RDMA write request comprises first data and a data persistence mark, and the data persistence mark is used for indicating that the first data is to-be-persisted data; according to the RDMA write request, the first RNIC sends the DMA write request to the first processor to instruct the first processor to write the first data into the first device, the first RNIC and the first processor belong to the first device, the second RNIC belongs to the second device, and the first RNIC and the second RNIC communicate with each other based on an RDMA mode; and according to the data persistence mark, the first RNIC determines that the first data is to-be-persisted data, and the first RNIC instructs the first processor to store the first data into a nonvolatile memory of the first device. Therefore, the load of the RDMA network in the remote memory persistence process is reduced.

Description

technical field [0001] The application relates to the field of computer technology, in particular to a data processing method, a remote direct access network card and equipment. Background technique [0002] Storage class memory (storage class memory, SCM), such as 3D Xpoint, is a new type of non-volatile memory (non-volatile memory, NVM), which is a combination of traditional storage media (such as mechanical hard disk, solid state Hard disk, etc.) and memory (such as dynamic random access memory) composite memory. SCM can be embedded in the slot of the mainboard like dynamic random access memory. Compared with dynamic random access memory, SCM can still save data uninterruptedly when the power is lost, and has the feature of power-off storage. SCM can provide faster read and write speeds than flash memory, and is cheaper than dynamic random access memory in cost. In some computing device system architectures, SCM is used for memory usage. In some solutions, a plurality ...
