Parallel processing-based multi-host interface redundancy SAN controller

Abstract

The invention relates to a parallel processing-based multi-host interface redundancy SAN controller and belongs to a controller. The structure of the parallel processing-based multi-host interface redundancy SAN controller comprises a controller redundant module A, a controller redundant module B and a backboard module C, wherein the controller redundant module A is connected with the controller redundant module B by a high-speed PCIE bus P1 and is connected with the backboard module C by a non-high speed mutual connection access PA; the controller redundant module B is connected with the backboard module C by a non-high speed mutual connection access PB. Compared with the prior art, the parallel processing-based multi-host interface redundancy SAN controller adopts double controller double DMA channel parallel processing, a structure configured with two redundancy controller modules, and parallel processing of RAID and other data in each controller redundancy module and between the two controller redundancy modules and can greatly improve the whole performance of the controller without losing reliability.

Description

technical field [0001] The invention relates to a controller, in particular to a multi-host interface redundant SAN controller based on parallel processing. Background technique [0002] In today's network age, storage technology is undergoing revolutionary changes. The reason leading to this revolutionary change is firstly manifested in the rapid expansion of storage capacity. In the era of digitalization and the Internet, the widespread deployment of large-scale application systems poses a huge challenge to the performance and functions of network storage systems, mainly manifested in high performance, scalability, shareability, adaptability, manageability, and high reliability. [0003] SAN (Storage Area Network) is a storage sharing network established to make full use of storage resources, which increases and facilitates the connectivity between storage and hosts. Just like the well-known LAN, SAN greatly improves the scalability and stability of the connection betwe...
