Problems solved by technology

[0002] As disk-based technologies become more mature and prices continue to decrease, more and more manufacturers introduce virtual tape libraries (VTL). However, the controllers of most VTL products currently on the market are based on a single PC server Even if a PC server with high scalability is used, its expansion capability is still limited, and many necessary functions integrated on the VTL controller, such as: logical volume management, data compression, deduplication, automatic verification , encryption, etc., also make the CPU of a single server overwhelmed

Abstract

The invention discloses an embedded type virtual tape library parallel memory system, which mainly comprises a hardware part and a software part, wherein the hardware part comprises an intelligent expanding engine group, a core exchange system and a memory unit. Core virtual tape library management software is run on the platform, and various functions in the parallel virtual tape library system are realized. The embedded type virtual tape library parallel memory system adopts a parallel controller engine structure, and a plurality of engines parallel work and simulate the working state of one tape library. The hardware structures of the engines of the controller are the same and are all based on the adoption of a specially designed main board, and a specially designed control chip and virtual tape library software are integrated on the main board. The number of the parallel engines can be expanded to 32, each engine can be configured with 2 optical fiber host channels and 6 back end optical fiber memory channels, and the optical fiber channels self-adapt to the transmission rates of 2Gb/sec and 4Gb/sec. The multi-engine parallel system design can maximize the I/O performance and memory capacity of the virtual tape library (VTL).

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to an embedded virtual tape library parallel storage system. Background technique [0002] As disk-based technologies become more mature and prices continue to decrease, more and more manufacturers introduce virtual tape libraries (VTL). However, the controllers of most VTL products currently on the market are based on a single PC server Even if a PC server with high scalability is used, its expansion capability is still limited, and many necessary functions integrated on the VTL controller, such as: logical volume management, data compression, deduplication, automatic verification , Encryption, etc., also overwhelm the CPU of a single server. Contents of the invention [0003] In view of the problems referred to above, the purpose of the present invention is to introduce a kind of multi-VTL engine, so that data transmission and processing can be implemented in a distrib...
