摘要： The present invention provides a system, method, and computer program product that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. Specifically, a mechanism for providing and using a linear block address (LBA) translation protection table (TPT) to control out of user space I/O operations is provided. In one aspect of the present invention, the LBATPT includes an adapter protection table that has entries for each portion of a storage device. Entries include access control values which identify whether the entry is valid and what access type operations may be performed on a corresponding portion of a storage device. I/O requests may be checked against these access control values to determine if an application instance that submitted the I/O requests may access the LBAs identified in the I/O requests in the manner requested.

摘要： A system, method, and computer program product that enables user space middleware or applications to pass I/O storage requests directly to a network attached storage device via a storage server that performs authentication are provided. A mechanism is provided for using a translation protection table (TPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), or logical volume protection table (LVPT), to control user space and out of user space Input/Output (I/O) operations. The storage server performs authentication of an application instance's request to open an operating system logical volume and, upon being authenticated, permits the application instance to submit I/O storage requests via the TPT to the opened OS logical volume. I/O storage requests are translated into storage commands using the TPT and the storage commands are encapsulated for transmission via one or more networks to the storage server.
