Massive memory system based on multi-channel memory equipment and its control method

Abstract

The present invention discloses one kind of massive memory system based on multi-channel memory device, and the massive memory system includes server and memory devices, each of which includes system unit channel, memory device, network interface module and array operation controlling module. The interface module is connected via PCI bus to the array operation controlling module to constitute multi-channel memory device; the server accesses the system unit channel via peripheral adaptor; and the memory devices are connected to network the same as or different from the server via individual network interfaces. The system adopts control method with separated command flow and data flow. The present invention has the advantages of good system expandability, high parallel performance, high management efficiency and high performance, and raised average data transmitting rate.

Description

technical field [0001] The invention belongs to the technical field of storage, and in particular relates to a mass storage system based on a multi-channel storage device and a system control method thereof. Background technique [0002] In recent years, all kinds of shared and exchanged data information has increased dramatically at an incredible speed, resulting in a continuous and explosive increase in the capacity and bandwidth of storage products. For example, in many cutting-edge subject research fields (such as human genes, climate analysis, etc.), the required storage capacity is at least 1TB, and the capacity demand is still increasing. At the same time, with the popularization of the network and the promotion of multimedia applications, the requirements for storage service bandwidth are also increasing simultaneously, and some important topics even require a bandwidth of 1TB / S. However, the existing storage system is restricted by the single connection mode betwee...

AI Technical Summary

Problems solved by technology

However, the existing storage system is restricted by the single connection mode between the server and the storage device. Although it can meet the capacity requirements by accumulating high-density and large-capacity storage devices, it cannot increase the storage bandwidth at the same time.

Moreover, the I / O data on a large number of storage devices needs to be forwarded to the client through the server. This working mode not only easily leads to peripheral channel congestion, but also increases system overhead due to multiple storage and forwarding in the process of data access and transmission. and transmission delay, resulting in lower average data transmission rate and longer service waiting time

Especially when a large number of customers send requests, the above problems will become more prominent, forming a "server bottleneck"
