Virtual Hard Drive Technology For Server And Clients

VDSA(the Virtual Disk System Architecture) is the top technology researched and developed by Shenzhen SunTang Technology and has got a patent right. Supported by VDSA Server, thin clients (diskless terminals) can run the operating system and application software directly without a local hard disk. With VDSA technology, the whole local network works like a single computer. Working with the independent computing of single computer and the distributed computing of network makes rational sharing of hardware and software resource. VDSA technology also has solved the problem of information-island of computer network at present. So far, the system adapting the VDSA technology has able to run with operating systems such as Microsoft Windows 9. X, Windows 2000, Windows XP, Linux and their application software. The technology architecture of VDSA is constituted with: VDSA-Operating System: Supports thin clients to run the operating system on virtual image of VDSA server. VDSA-Application: Supports thin clients to run the application software on virtual image of VDSA server. VDSA-Data Bank: Provides data storage room for client individual users. From network architecture, VDSA contains several elements as below: Server: Network virtual disk servo system(data process and files control), server chief-control system(login management, virtual disk manage, long-distance manage, user operating environmental manage system)Network: The support and management of protocol like IPX, TCP/IP, PXE, EFI etc. Client: OS image manage systemTo be simple, the network structured with the VDSA technology has many advantages as:
The whole network works like a single computer;
No need to manage to clients;
No need to install operating system on clients;
No need hard disk on clients;
No junk files will be created on clients;
Clients can be protected from all known and unknown virus;
Only need to manage/ maintain the server, all clients can run the upgraded software on the network; The network structured with VDSA technology has a much lower TCO(Total Cost of Ownership), a much higher performance capability and lower price rate meets national conditions/requirements and international technology development trend. Moreover, in a sense, where there are personal computers, there should be system like this. Thus, the VDSA technology and its products have a large application range. Some solutions with operability in China at present are: Education solution (e-classroom, e-reading room, and campus network), net cafe solution (internet surfing and game), office automation solution (e-government, ERP, financial and taxation system), financial and commercial terminals solution (security terminal, commercial POS), etc..
