System and method for raw device mapping in traditional NAS subsystems
Abstract:
A method is provided for data storage management in a virtualized information handling system that includes a first and second network storage resource, a hypervisor allowing multiple virtual machines to run on the virtualized information handling system, and a data access agent. The data access agent may intercept a data access request initiated by a virtual machine and intended for the first network storage resource. In response to intercepting the data access request, the data access agent may establish a connection with the first network storage resource, and retrieve from the first network storage resource metadata associated with the data access request. The retrieved metadata may identify a location of the second network storage resource. Additionally, the data access may establish a connection with the second network storage resource using the location of the second network storage resource identified by the retrieved metadata. The virtual machine may complete the intercepted data access request via the established connection with the second network storage resource.
