Abstract:
Systems and methods of storage device access are provided, where the operating system copies permission and mapping information to the storage array and/or to the application program's memory. The application program can then access the storage device without the operating system's intervention and the storage device will check whether the application has permission to access the data. As a result, in most cases, neither the operating system nor the file system needs to be invoked, and since both of them increase the amount of time required to access the data in the file system, considerable performance improvements are possible.
