Heterogeneous Network Storage Sharing Technology

In the research areas of storage technologies, the widely accepted mainstream technologies is Fibre-Channel (FC) based Storage Area Network (SAN). For this reason, many foreign and native companies put so much resource in the research and development of SAN and its related products. SAN has provided a convenient way to connect storage sub-system with present LAN, so storage capacity can be appended independently and network performance will not be affected by data transference. In addition, this kind of centralized network storage model makes remote and unattended management possible. In the consideration of this situation, I have done a full research in SAN and related technologies in general and cross-platform network storage sharing in specific and it is summarized as below:1. In the design of cross-platform (UNIX and Windows) network storage sharing system, I have brought forward several optimizing methods, such as asynchronous I/O mode, I/O buffering and double buffers. This makes the system more efficient to share the SAN storage sub-system.2. Designed universal backup/restore system based on the cross-platform network storage sharing system, utilizing merits of several SAN backup solutions, which realizes an integrated backup/restore method of main frames and open system.
