Low-cost data storage method

Abstract

The invention provides a low-cost data storage method. Storage resources are integrated, and two mainstream protocols of FC and iSCSI present SAN (storage area network) are coordinated, so as to realize high-reliability available data storage at low cost, thereby exerting the respective advantages of the FC and the IP-SAN, and achieving the optimal cost performance of the data storage. The system structure of the low-cost data storage method comprises a data storage unit, a storage protocol conversion unit, a high-speed exchanging unit and an application server unit. A system maps the whole or partial space of the original storage system to the storage protocol conversion unit by the FC protocol, the storage protocol conversion unit carries out secondary mapping on the space by the iSCSI protocol and finally maps to an application server by an Ethernet switch, the primary FC mapping is realized by FC Target software of the FC storage system, and the secondary mapping is realized by the iSCSI Target software.

AI Technical Summary

Benefits of technology

Introduction: When multiple applications require access from different devices at once or with high data rates, it becomes expensive due to limited resources available within one device's network connection. To solve these issues, some methods have been developed where only specific connections between clients should work together instead of all connected computers working simultaneously. These techniques reduce costs but still maintaining their ability to communicate over long distances without losing any significant amount of power.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the efficiency and effectiveness of storing large amounts of digital content on disk drives without increasing costs associated therewith. Current approaches involve purchasing expensive components like cables and connecting them directly between devices and servers. There is currently no efficient way to implement these connections within the industry.
