An intelligent distributed virtual server for providing distributed services to a plurality of clients, including one or more servers units, each server units storing data and providing services for accessing by one or more clients; a switch for connecting the clients to the server units and to provide a communication link; and a distribution control station connected to the clients and the server units via the switch, wherein the distribution control station receives a request for a service from a client, and automatically, selectively establishes a data link between that client and an server unit, which stores the requested data and provides services, such that the server unit provides the data stream to the client via the communication link, independent of other server units. The capacity of the intelligent distributed virtual server can be dynamically expanded without interrupt the normal server operation. Due to the non-shared accessing between server units, it represents a more efficient model for computing in terms of the resources usages. It can provide distributed computing cross intra-net or Internet. In addition, it provides scalability and all intelligent services such as real time fault handling, security and others.

The present invention relates generally to distributed virtual server, and more particularly to distributed intelligent virtual server.
a) Basic Terminology:
Disk Drive: Provide computer host system with block data through special cable access such as IDE or SCAI cable depends on type of disk drive.
These and other features, aspects and advantages of the present invention will become understood with reference to the following description, appended claims and accompanying figures where:
FIG. 1A) shows an example simplified block diagram of an embodiment of a distributed virtual server including NAS, SAN or other server units according to the present invention;
FIG. 1B) shows an example block diagram of an embodiment of an NAS, SAN or other server unit;
In the drawings, like elements are designated by like reference numbers.
FIG. 1A shows a simplified block diagram of a distributed intelligent virtual server (10) according to this present invention. The distributed virtual server (10) comprises one or more server units (12) connected to a distribution control station (14) via one or more switches or routers (16). One or more client devices (e.g., personal computers (18) are connected to the distribution control station (14) via a communication network (17). Each server unit (12) stores data (13) for accessing by clients (18), wherein the distribution control station (14) maintain a list (15) (FIG. 2B) of information (13) from each sever units (12).
In one example, the distribution control station (14) hosts a virtual block data server (SAN) Web site to perform administration tasks and distribute client's disk volumes requests to specific server units (12) up to the maximum concurrent client volume requests that each block data server unit (12) can handle. In another example for the IP based distributed virtual SAN (block data server), the distribution control station (14) maintains a list (15) of information (13) from each SAN units (12), which will be the list of volumes with specific type, size, address of the block data as well as the IP address of each block data server units.
