Abstract

The invention provides a data interaction method and system, a storage medium and equipment, and the method comprises the steps of selecting a master end and a slave end between same-level expanders according to a preset rule, and selecting a preceding-level expander as the master end and selecting a backward-level expander as the slave end between cascaded expanders; establishing a page for data interaction between the same-level expanders, and establishing a page for data interaction between the cascaded expanders; enabling the master end to send an instruction with information of a specified expander port through the page, and receiving the instruction by a specified slave end of which the port is the specified expander port; in response to the instruction received by the specified slave end through the page, judging whether the specified slave end is a target slave end based on the instruction; and in response to the fact that the specified slave end is not the target slave end, synchronizing the instruction to the target slave end at the same level as the specified slave end through page so as to enable the target slave end to execute the instruction. According to the invention, the data interaction rate can be effectively improved, the reliability and integrity of data transmission are ensured, and the data processing rate of the whole storage system is further improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a data interaction method, system, storage medium and equipment. Background technique [0002] In the era of cloud computing and big data, mass data storage requires storage products with better performance and faster transmission rates to meet higher transmission rates while ensuring data integrity and reliability. This requires large systems and expander( A firmware for connecting expansions), the interaction between expanders and expanders requires a better transport protocol. [0003] In the storage system, the CPU uses the pcie (peripheral component interconnect express, high-speed serial computer expansion bus standard) interface to process business data, and the hard disk uses the SAS (Serial Attached SCSI) interface, so there will be a conversion from pcie to a SAS interface, and it will be connected by a SAS expander to each hard drive. [0004] For data s...
