Problems solved by technology

The advantage of this technology is that the controller has data transmission and error termination functions, and does not require the host computer operating system to handle disk error events or controller failure events. However, this technology is expensive and requires the cost of the adapter , more functional controllers are needed to set up this set of disk array systems, and ordinary people cannot afford such high costs, so the industry will try their best to develop a set of low-cost and practical disk array systems to solve the above problems

Embodiment Construction

[0030] A disk array system of the present invention uses a kind of software installed on a host computer to process data transmission problems between the disk array system and the host microprocessor. Its hardware architecture is shown in Figure 1. The host computer 100 contains A microprocessor 110 is installed with a software (not shown in the figure). The software has the ability to fail over the inoperable channels 131-134 and 231-234, and to transfer the data transmitted from the microprocessor or the disk back to The data of the host is load balanced. The microprocessor 110 of the host 100 transfers the data out of the host 100 via the bus 120 via the channels 131-134, and transfers the data to the controller 200 via the channels 231-234, and then the controller 200 The bus 240 is transferred to the disk array processor 210, and the memory 220 stores error termination and load balancing instructions and data buffering functions, restores and transmits the data to the bus 25...

Abstract

The invention relates to a disk array system with fault ending and load balance which is used for storing the data of a master computer. It includes: a micro computer processor which is controlled by a software to possess the function of the master computer with fault ending and the load balance, a first bus used to transmit the data from the micro processor, wherein the first bus possesses a plurality of communication channels, at least one controller which is connected with the first bus, a storage with the function of data buffer and the order transmitted by the micro processor which is connected with the controller, a second bus with a plurality of second communication channels wire which is connected with the controller, and a plurality of disks which are connected with the plurality of communication channels.

Description

Technical field [0001] The invention relates to a disk array system, in particular to a disk array system with error termination and load balancing. Background technique [0002] Modern computer systems require a large amount of storage devices to accommodate large amounts of data. A Disk Array System (RAID) in which a host computer and a controller control multiple disks is a solution often provided by computer industry. A more complete data storage system must have the functions of regular data backup, detecting faulty disks, detecting faulty controllers, and balancing data load balancing. The above-mentioned functions can be achieved by using a host computer with a host bus adapter (HBA), and by connecting multiple disks to the controller. For example, US Patent No. 6578158 "Provides a method for transmission error termination and error return disk controller "And its devices" refers to a host computer with a host bus adapter, two hubs each connected to two data transmission p...
