  • System and method for simulating a persistent byte addressable storage device on a persistent block addressable storage device
    Patent number: 9389787
    Abstract: A persistent random-access, byte-addressable storage device may be simulated on a persistent random-access, block-addressable storage device of a storage system configured to enable asynchronous buffered access to information persistently stored on the block-addressable device. Buffered access to the information is provided, in part, by a portion of kernel memory within the storage system allocated as a staging area for the simulated byte-addressable storage device to temporarily store the information destined for persistent storage. One or more asynchronous interfaces may be employed by a user of the simulated byte-addressable device to pass metadata describing the information to a driver of the device, which may process the metadata to copy the information to the staging area. The driver may organize the staging area as one or more regions to facilitate buffering of the information (data) prior to persistent storage on the block-addressable storage device.
