In this paper, the authors have constructed a low cost virtually single storage private grid using Object based Grid Architecture (OGA). In OGA the data, process privacy and inter communication are increased through an Object Oriented concept. In general, the grid is affected, without, scheduling down time and dedicated resource. Then user or grid application is responsible to select the resource where the file or the replica should be stored. To overcome this, in their design, local PC running grid manager service can act as grid resource. System up is intimated to the middleware and details are maintained in ROT. MIS is responsible to select the resource where the file or the replica should be stored.
