TH-MSNS: A High Scalable Network Storage System
Shu Ji · Chinese Journal of Computers · 2005
With the increasing demand for vast storage repositories, network storage become s important to mass data storage and processing, scalable addressing and availab ility, the quality of service (QoS) and security of data storage. In this pape r, authors gave a design and implementation of storage area network system with the name TH-MSNS, which has high scalability. With dual HBA, dual I/O nodes it has high availability and high performance, and the total capacity reaches on 26 0TB. An introduction of TH-MSNS’s architecture, SCSI Target Simulator, embedde d operating system (EOS) and storage management. The basewares of TH-MSNS hav e following characteristics: the SCSI Target Simulator adopts layered implementa tion, which provides compatibility for different SCSI devices and different netw ork protocols; all key software run in the EOS kernel, which improves the perfor mance greatly; storage management adopts distributed architecture. It is fully i ndependent to OS and has functions such as the object management, device auto-d etection, access controller and log, etc. Compared with other FC-SAN system, it shows some characters such as scalability, high performance, and high compatibi lity, and the whole system is easy to be maintained.
