Embodiment

[0035] 1) The stored data information is sent to the high-speed expansion bus. The transmission of bus data generally requires the control bus, address bus, and data bus. First, the storage controller obtains the control right of the bus network port through the arbitration mechanism of the data switch control chip;

[0036] 2) Obtaining the control right of the bus network port can be optimized according to the resource scheduling strategy of the entire multi-control system, so as to promote the perfect combination of bus usage efficiency and arbitration mechanism in the system;

[0037] For example: figure 1 Data transmission from controller 1 to controllers 2 and 3:

[0038] A. First, control 1 applies for control of the bus port through the idle control bus;

[0039] B. The destination address data of control 1 is transmitted to the bus data switch, and its decision-making control chip connects positions 1 and 2 to release the bus control application;

[0040] C. Contro...

Abstract

The invention provides a high-speed interconnecting method of controllers of a tight-coupling multi-control storage system. According to the high-speed interconnecting method of the controllers in a tight-coupling multi-control storage system, resource scheduling and coordination of the controllers in the multi-control storage system through a system program, so that data transmission among different controllers is achieved. A storage controller CPU packages decision information and sends the packaged decision information to a high-speed bus extended by a north bridge. A data exchanger analyzes objective information in data, adjusts connection status of the bus which is compared with a local FW corresponding table and achieves data directed transmission among multiple controls. With regard to a clustered storage system formed by the controllers which are coupled, some manufactures adopt storage node stacking, while some manufactures only adopt control unit stacking, and no matter what kind of modes are applied, the modes have the common advantages that production cost is reduced and the manufacturers are made to form a large-scale storage system through a standardized module combination, so that the requirement of a large-scale application system for the storage capacity and performance can be met. Through the standardization, cost allowance of a production process can be reduced, and the research and development cycle of the system can be shortened.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a high-speed interconnection method between controllers of a tightly coupled multi-control storage system. Background technique [0002] After the development of storage technology in recent years, the development direction of disk array controller architecture has obvious differences. There are clustered storage systems (EMC V-MAX, IBM IXV, HP 3PAR, etc.) that are coupled with controllers, and storage systems that are composed of distributed multi-layer controllers (HDS VSP, EMC DMX). The former is a stack of modular storage, and standard external interconnection technologies are used between each node, such as Gigabit Ethernet, RapidIO, and infiniband. The latter adopts a layered direct interconnection method. Each layer of controllers contains multiple interconnection interfaces, and the system is directly interconnected through multiple data interfaces. The tw...
