Abstract

The embodiment of the invention provides a bus adapter and a data transmission method. The method comprises the steps that the bus adapter comprises a data protocol conversion module, a first interface and a second interface; the data protocol conversion module is connected with the first interface and is used for carrying out NVMe protocol-based data communication with a host through the first interface; the data protocol conversion module is connected with the second interface and is used for carrying out data communication with external storage equipment through the second interface based on a data protocol with the external storage equipment; and the data protocol conversion module is used for performing data conversion between an NVMe protocol and a data protocol of external storage equipment. According to the embodiment of the invention, special development and maintenance of a custom protocol and a drive program of HBA are not needed, so that the development time and the operation and maintenance cost of the HBA are greatly saved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a bus adapter and a data transmission method. Background technique [0002] Serial connected small computer system (Serial Attached SCSI, SAS), serial port advanced technology connection (SerialATA, SATA) and other storage devices need to work through the host bus adapter (HostBusAdaptor, HBA). The expansion bus standard (Peripheral component interconnect express, PCIe) interface forwards SAS, SATA and other interface information to achieve the purpose of the host accessing the storage device. As we all know, the device application layer of the SAS interface follows the Small Computer System Interface (SCSI) protocol, and the device application layer protocol of the SATA interface is the Advanced Technology Attachment (ATA) protocol, so the HBA controller needs to integrate the SCSI protocol and the ATA protocol. Convert to a protocol suitable for the PCIe interface. At presen...
