Description
Technical Field
The present invention relates to a data storage device, and more particularly, to a data storage device with a capability of self-accessing file data.
Background
With the need for data storage, data storage devices (Solid State Drive, SSD) are often used by hosts to store important data. Fig. 1 is a schematic structural diagram of a conventional data storage device. As shown in fig. 1, the conventional data storage device 10 includes a controller 11, a plurality of flash memories 13 and a data transmission interface 15. The controller 11 is connected to the flash memory 13 and the data transmission interface 15.
The data storage device 10 is connected to a host 20 through a data transmission interface 15. The data transmission interface 15 is a data transmission interface of a standard specification commonly used by an operating system, such as a data transmission interface conforming to SATA or PCIe standard specification. When the operating system 21 of the host 20 wants to access data to the data storage device 10, an access command (e.g. a read/write command) is issued to the data storage device 10 via a driver 23 (e.g. SATA or PCIe driver) of a data transmission interface, and then the controller 11 of the data storage device 10 accesses the data to the flash memory 13 after receiving the access command.
The operating system 21 of the host 20 typically has a file system 22 built therein, which is a subsystem of the operating system. The file system 22 stores data in the data storage device 10 in the form of files or reads data from the data storage device 10 in the form of files. When the operating system 21 of the host 20 accesses data from the data storage device 10, the accessed data is in the form of raw data (raw data), and the operating system 21 parses the accessed raw data through the file system 22, for example: and analyzing the file name, file type or file attribute of the original data so as to manage or operate the file of the analyzed original data.
Furthermore, the controller 11 of the conventional data storage device 10 is not usually installed with an operating system, so that during the data access process, only the original data can be accessed, and further file analysis cannot be performed on the accessed original data. Still alternatively, if the controller 11 of the data storage device 10 is installed with an os, however, the data transmission interface between the controller 11 and the flash memory 13 is a standard data transmission interface commonly used by a non-os, such as an SPI, I2C or UART data transmission interface, so that the file system of the os can analyze the file information of the data transmitted between the controller 11 and the flash memory 13, and the engineering personnel need to write and build a driver of the non-standard data transmission interface in the file system of the os, which is complex and has very low access efficiency.

Detailed Description
Fig. 2 is a schematic structural diagram of a data storage device according to an embodiment of the invention. As shown in fig. 2, the data storage device 30 of the present invention may also be a Solid State Disk (SSD), which includes a microprocessor 31, a data storage unit 33, and a data transmission interface 35. The data storage unit 33 includes a controller 331 and a plurality of flash memories 333, and the controller 331 is connected to the flash memories 353 through a serial transmission interface, such as SPI, I2C, UART serial transmission interface. The microprocessor 31 is connected to the data storage unit 33 via a data transmission interface 35. The data transmission interface 35 of the present invention may also be a data transmission interface of standard specifications commonly used in operating systems and be a high-speed data transmission interface, such as a data transmission interface conforming to SATA or PCIe standard specifications.
In the present invention, the microprocessor 31 is installed with a first operating system 311. The first operating system 311 may also be an embedded operating system, such as a Linux or RTOX architecture operating system. The first operating system 311 includes a first file system 312, which may be a file system in FAT, NTFS or exFAT format. Furthermore, the first file system 312 is provided with a driver 313 related to the data transmission interface 35.
When the microprocessor 31 of the data storage device 30 receives an external data access request 501, the first operating system 311 of the microprocessor 31 issues an access command (e.g. a read/write command) to the controller 331 via the driver 313. The controller 331 performs a data access operation to the flash memory 333 according to the access command. During the data access operation, the data transmission interface 35 between the controller 331 and the microprocessor 31 will transmit a raw data (raw data) associated with the data access request 501. The first file system 312 performs a file parsing process on the original data to parse a file of the original data, for example: the first file system 312 parses the file name, archive type, or file attributes of the original data. Here, the first operating system 311 parses the accessed original data through the first file system 312, and then performs file management or file operation on the original data.
The data storage device 30 further includes a network communication component 39. The microprocessor 31 is connected to the management platform 50 via the network communication module 39. The management platform 50 may also be an intranet management platform or a cloud management platform. The network communication device 39 is a WiFi communication device, an ethernet communication device, or a 4G or 5G communication device. The data access request 501 may also be issued by the management platform 50.
In an embodiment of the present invention, the data access request 501 sent by the management platform 50 is an access request for updating system data or firmware data, and the data access request 501 includes an original data for updating system or firmware. When the microprocessor 31 of the data storage device 30 receives the data access request 501, the first operating system 311 of the microprocessor 31 sends an access command for updating system data or firmware data to the controller 331, and the first file system 312 is utilized to parse file information of the original data updated by the system or firmware.

When the microprocessor 31 of the data storage device 30 receives the data access request 501, the first operating system 311 of the microprocessor 31 issues a read command of the health data to the controller 331, the first operating system 311 reads the health raw data from the flash memory 333 through the controller 331, and the file information of the health raw data is resolved by the first file system 312. After parsing the health data file, the first operating system 311 transmits the health data file to the management platform 50 through the network communication component 39.

The TRIM function is a function built into the data storage device 30 and can optimize the execution of garbage collection (Garbage Collection) procedures by the data storage device 30. When the microprocessor 31 of the data storage device 30 receives the data access request 501, the first operating system 311 of the microprocessor 31 starts the TRIM function of the data storage device 30 and issues a data access command of the TRIM function to the controller 331. The controller 331 performs a garbage collection (Garbage Collection) procedure on the data blocks of the flash memory 333 according to the data access command of the TRIM function to actively erase the invalid data stored in the data blocks or actively move the valid data stored in the data blocks to other data blocks. In addition, during the process of executing the garbage collection procedure, the first operating system 311 uses the first file system 312 to analyze the file information of the invalid data and the valid data, so as to erase the file of the invalid data or concentrate the file of the valid data in the continuous data blocks. Then, the data storage device 30 is executed by the TRIM function, so as to improve the access efficiency of the data storage device 30.
In the above embodiment, only some embodiments of the present invention are implemented, and in practical application, the management platform 50 can issue various data access requests 501 to the data storage device 30, so that the first operating system 311 of the microprocessor 31 of the data storage device 30 can execute a specific operation according to the data access requests 501 and use the first file system 312 to parse the file information of the data accessed during the execution of the specific operation.

Further, a switch 37 is provided in the channel of the data transmission interface 35. The switch 37 is a channel switch of a SATA data transmission interface or PCIe data transmission interface. The microprocessor 31 determines whether the data of the data storage unit 33 is accessed by the second operating system 41 of the host 40 or the data of the data storage unit 33 is accessed by the first operating system 311 of the microprocessor 31 by controlling the switching of the switch 37. Referring to fig. 3, when the host 40 is operating normally, the microprocessor 31 sends a first level signal (L) to the switch 37, and the switch 37 turns on the channel of the data transmission interface 35 between the data storage unit 33 and the host 40. When the channel of the data transmission interface 35 between the data storage unit 33 and the host 40 is turned on, the second operating system 41 of the host 40 issues an access command to the controller 331 via the driver 351 according to the data access request 501, and the controller 331 performs a data access operation on the flash memory 333 according to the access command. During the data access operation, the data transmission interface 35 between the controller 331 and the host 40 will transmit an original data (raw data) associated with the data access request 501, and the second file system 42 will perform a file analysis procedure on the original data to analyze the file information of the original data. Then, the second operating system 41 performs file management or file operation on the parsed original data.

When an abnormal condition occurs in the host 40, such as the second operating system 41 of the host 40 is damaged, the first operating system 311 of the microprocessor 31 will take over the data access of the data storage unit 33. The microprocessor 31 sends a second level signal (H) to the switch 37, and the switch 37 turns on the channel of the data transmission interface 35 between the data storage unit 33 and the microprocessor 31, so that the first operating system 311 of the microprocessor 31 performs data access operation on the data storage unit 33 of the data storage device 30 according to the data access request 501. Furthermore, in the embodiment of fig. 3, the channel switching of the data transmission interface 35 is determined by the microprocessor 31.

Then, when the second os 41 of the host 40 is abnormal, the management platform 50 may also issue a data access request 501 for repairing the os to the microprocessor 31, and the data access request 501 includes a system restored original data.

Then, the controller 331 repairs the second operating system 41 stored in the flash memory 333 of the data storage unit 33 by using the system restore file according to the access command for repairing the operating system data. When the second operating system 41 of the host 40 is repaired, the host 40 can perform the data access operation again on the data storage unit 33 of the data storage device 30. Furthermore, the system restore file is a large data volume file, and the microprocessor 31 is connected to the controller 331 through the high-speed data transmission interface 35, so that the controller 331 can quickly receive the system restore file transmitted by the microprocessor 31 to repair the second operating system 41 in the flash memory 333. The microprocessor 31 is connected to the data storage unit 33 via a high-speed data transmission interface 35, so that the microprocessor 31 can access the data storage unit 33 at high speed.
