Abstract: A method for providing access to mainframe data objects in a heterogeneous computing environment includes providing, by a non-mainframe server, a service comprising a storage virtualization system for storing mainframe data in a virtual storage device. The mainframe data is managed by a mainframe server, which is connected to a physical storage device and to the server so that the virtual storage device in the storage virtualization system appears as another physical storage device to the mainframe server. The method includes receiving, by the server, a message from a non-mainframe client connected to the server via a network, wherein the virtual storage device appears as a mounted storage drive to the client, and the message includes a request for access to the mounted storage drive and/or to data stored therein. The request is processed to generate a non-mainframe formatted request result, which is transmitted to the client via the network.
