AI Technical Summary

Technical Problem

Existing multi-port storage systems have the following problems: high processor utilization, low overall system performance, difficulty in application development, poor system portability, poor system real-time performance, and inconvenient system debugging.

Method used

A multi-port storage acceleration system that uses software and hardware collaboration, through the design of the host, acceleration device and storage disk, uses the hardware unit to provide configuration registers for physical cable connection relationships and the firmware unit to provide storage protocols, merges the protocol interfaces of different types of storage disks, shields the differences between controllers and storage protocols, and reduces the amount of host driver and protocol development.

Benefits of technology

It effectively reduces the host processor utilization, improves the overall system performance and portability, reduces the difficulty of application development, and improves the system's real-time performance and debugging convenience.

Abstract

The present invention proposes a multi-port storage acceleration system with software and hardware collaboration, comprising: a host, an acceleration device, and a storage disk. The host is used to provide an operating environment for system software and is connected to the acceleration device through a virtual protocol host end inside the host. The acceleration device includes a hardware unit and a firmware unit. The hardware unit is used to provide a configuration register for the physical cable connection relationship between different types of controllers and device ports. The firmware unit is used to provide multiple storage disk controller drivers and storage protocols, and provides a virtual protocol device end interface that communicates with the virtual protocol host end inside the host, and is used to merge the storage protocol interfaces of different types of storage disks into a unified storage protocol interface. The storage disk is connected to a hardware bus hanging under the acceleration device port and serves as a terminal device to store data sent by the host, effectively improving the processor utilization rate, overall system performance and system portability in the multi-port storage acceleration system.
