Abstract

The invention discloses a RapidIO bus-based RAID storage system and method. The system comprises a RapidIO CPU node module, a RapidIO storage module and a RapidIO exchange network module, wherein the RapidIO CPU node module executes a RapidIO driver, a RapidIO storage driver, an MEM system and the like; the RapidIO storage module is mainly an exchange network consisting of a RapidIO exchange chip; and the RapidIO exchange network module consists of an FPGA chip and an RAID array consisting of n SATA hard disks, and the FPGA chip is connected with the RAID array. According to the system and the method, due to transmission in reliable, efficient, low-delay, direct memory sharing, interrupt and message modes, the RAID storage array can be directly connected with a RapidIO bus, and any RapidIO processor node can access the RAID storage array in a low-delay and high-bandwidth manner.

Description

technical field [0001] The invention relates to a RAID storage system and method, in particular to a RAID storage system and method based on a RapidIO bus. Background technique [0002] RapidIO (RapidIO is a high-performance, low-pin-count, packet-based interconnection architecture pioneered by companies such as Motorola and Mercury. It is an open system designed to meet and future high-performance embedded system requirements. It is mainly used in the internal interconnection of embedded systems, supports chip-to-chip, board-to-board communication, and can be used as a backplane (Backplane) connection for embedded devices. Because of its reliability, high efficiency, low latency, direct memory sharing, interrupt, and message transmission, it can be considered as a bus, and because it can connect multiple processor devices to make these devices form a network, it can also be considered as a bus. A kind of network. [0003] RAID (RAID is the abbreviation of Redundant Array ...
