SYSTEMS AND METHODS FOR A MASS DATA STORAGE SYSTEM HAVING A FILE-BASED INTERFACE TO A HOST AND A NON-FILE-BASED INTERFACE TO SECONDARY STORAGE

摘要

System and method for transferring data between a host system and a data storage system is provided. The system includes an interface that uses a file based protocol to transfer data between the data storage system and the host system, wherein the data storage system includes a first mass storage device and a second mass storage device; wherein the first mass storage device is a solid state non-volatile memory device and the second mass storage device is a non-solid state memory device. The first mass storage device is a flash memory device that operates as a primary storage device that stores data on a file by file basis. The second mass storage device is a magnetic disk drive that operates as secondary storage device and stores data received via a logical interface.

1. A data storage system, comprising:
a first non-volatile mass storage device configured to interface with a host system via a first interface which is configured to use a file based protocol wherein data is identifiable using a unique file identifier and an offset within a file, wherein the offset is configurable to point to a location in the file other than a beginning of the file; a second non-volatile mass storage device; a disk controller located on the second non-volatile mass storage device, wherein the disk controller is configured to facilitate data transfers between the second non-volatile mass storage device and the first non-volatile mass storage device; wherein the first non-volatile mass storage device is a solid-state non-volatile memory configured to operate as a primary storage device, wherein the second non-volatile mass storage device is a magnetic hard disk configured to operate as a secondary storage device, wherein the first non-volatile mass storage device includes a disk file system and disk driver for interfacing with the magnetic hard disk via a logical interface that maps data files from a file based protocol to a logical address space within the second non-volatile mass storage, wherein the second non-volatile mass storage device is configured to interface with the host only through the first non-volatile mass storage device, and wherein data from the host system can be stored in the first non-volatile mass storage device and/or the second non-volatile mass storage device, wherein the host system can access both the first and second non-volatile mass storage device using the file based protocol rather than the host system itself utilizing logical addressing to access the second non-volatile mass storage device.
