The present invention discloses a data access method and a storage subsystem implementing the method. The storage subsystem includes two storage virtualization controllers (SVC 1, SVC 2), a backplane, a physical storage device (PSD), and a clock generation circuit. The clock generation circuit is mounted on the backplane and provides a dedicated clock signal to the PSD. The PSD has a single port, and the lanes of the single port are divided into two half portions, each of which is coupled to one of the two storage virtualization controllers (SVC 1, SVC 2). Therefore, the present invention eliminates the need for additional intermediate components to couple the single-port PSD to the two storage virtualization controllers (SVC 1, SVC 2). This leads to simplified wiring and reduced costs, and the PSD will not be affected by failures of the intermediate components, thereby enhancing the redundancy architecture of the storage subsystem.

The method comprises the following steps: reserving target resources for a software-defined storage node in a physical server, so as to ensure normal operation of the software-defined storage node; creating a data network on the physical server based on a selected target pass-through network card, so as to use the data network as a communication network between the software-defined storage nodes in different physical server nodes and as a network for connecting the physical server by the hyper-converged software-defined storage to provide storage services; and constructing a storage space corresponding to the software-defined storage node by using a selected target physical disk. Therefore, the application improves the performance of the hyper-converged software-defined storage.

An access method of a storage device and a virtual device are provided. The storage device supports a single root input output virtualization (SR-IOV), the storage device is virtualized as at least two virtual functions (VFs), the access method comprises: in response to an input / output (I / O) request for the storage device by an application, transmitting the I / O request to a corresponding VF by a virtual machine, the VF writing a completion message of the I / O request to a completion queue (CQ); querying the CQ in a polling manner by a processor of the virtual machine; and if there is the completion message of the I / O request in the CQ, returning the completion message to the application by the virtual machine. Since the storage virtualization system processes I / O requests in a polling manner, this manner avoids the delay and overhead caused by the interruption, and enables the application to improve I / O efficiency, and finally enables the random parallel read and write performance of the virtual machine using SR-IOV technology to allocate high-speed SSDs, to be improved significantly.

This invention relates to the field of data processing technology and discloses a hybrid storage access scheduling method, system, and medium for storage virtualization. The method includes: collecting write access requests, as well as snapshot chain depth, hot flip count, and time interval. The urgency of the write access requests is determined, and it is judged whether temporary acceleration processing conditions are met. When met, a temporary acceleration mapping relationship is established, directing the access requests to the temporary acceleration mapping relationship. The access frequency of the target logical block segment, the write-back status of the high-speed storage layer, and the amount of additional writes in the snapshot chain are collected to determine whether the temporary acceleration mapping relationship meets the formal migration conditions. When the formal migration conditions are met, the temporary acceleration mapping relationship is converted into a formal mapping relationship. Otherwise, the temporary acceleration mapping relationship is revoked while the primary mapping relationship remains unchanged. This application improves the response to high-urgency write accesses and the smoothness of migration while maintaining the stability of the primary mapping relationship.
