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 that interfaces with a host system via a first interface that uses a file based protocol wherein data is identified 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; and a second non-volatile mass storage device; wherein the first non-volatile mass storage device is a solid-state non-volatile memory that operates as a primary storage device, wherein the second non-volatile mass storage device is a magnetic hard disk that operates 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 does not interface with the host except 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 accesses both the first and second non-volatile mass storage device using the file based protocol such that the host system itself does not utilize logical addressing to access the second non-volatile mass storage device, wherein data transferred between the second non-volatile mass storage device and the first non-volatile mass storage is facilitated by a disk controller located on the second non-volatile mass storage device. |
