In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 3, fig. 3 is a first embodiment of the file address optimizing method of the present invention, the method includes the following steps:
Step S110, when a file arrangement instruction sent by a server is received, determining a current address corresponding to a file to be arranged according to the file arrangement instruction.
In this embodiment, the server is configured to maintain a terminal, where the terminal is in communication connection with the server, and the server has authority to send an instruction to the terminal, where the file sort instruction is configured to instruct the terminal to move a file to be sorted, which is stored in a fragmentation manner, to the same physical block or multiple adjacent physical blocks, where the file to be sorted in a fragmentation manner may be understood as a disk fragment or a file fragment, because the file is stored in a dispersed manner in a different place of the entire disk, instead of being continuously stored in a cluster formed by continuously storing the file in a disk. After the hard disk is used for a period of time, because the file is repeatedly written and deleted, the idle sectors in the disk can be scattered to discontinuous physical positions in the whole disk, so that the file cannot exist in continuous sectors. Therefore, when the file is read and written again, the file needs to be read in different places, the back and forth movement of the magnetic head is increased, and the access speed of the magnetic disk is reduced.
Alternatively, the file sort command is a private command sent from the server to the terminal through a Small Computer System Interface (SCSI), which is an independent processor standard for a system-level interface between the Computer and its peripheral devices (hard disk, floppy disk drive, optical drive, printer, scanner, etc.). The SCSI standard defines the electrical characteristics of commands, communication protocols, and entities (in terms of OSI, occupying the physical, link, socket, application layers), most of which are applied to storage devices (e.g., hard disk, tape drive); however, in practice, SCSI may be connected to devices including scanners, optical devices (such as cds, dvds), printers … …, etc., and SCSI commands list supported SCSI peripherals. SCSI-1 is the most primitive version, with asynchronous transmissions at 3MB/S and synchronous transmissions at 5MB/S. Although almost eliminated, 25-pin interfaces are employed in some scanners and internal ZIP drives. That is, if a SCSI-1 device is coupled to your SCSI card, there must be an internal 25-pin interface cable; if an external device is used, any of the internal interfaces cannot be used (i.e., none of the internal interfaces is usable at this time). Early SCSI-2, called FastSCSI, can connect 7 peripherals by increasing the synchronous transmission frequency to increase the data transmission rate from original 5MB/s to 10MB/s, supporting 8-bit parallel data transmission. And WideSCSI which appears later supports 16-bit parallel data transmission, the data transmission rate is also improved to 20MB/s, and 16 peripherals can be connected. The SCSI version uses a 50 pin interface, mainly for scanners, CD-ROM drives, and old hard drives. In 1995, a higher speed SCSI-3, called UltraSCSI, was created, and the data transfer rate also reached 20MB/s. It improves the synchronous transmission clock frequency to 20MB/s, and improves the data transmission rate. If the 16-bit transmission Wide mode is used, the data transmission rate can be further improved to 40MB/s. This version of SCSI uses a 68 pin interface, primarily for hard disk applications. The typical feature of SCSI-3 is to greatly increase the bus frequency and reduce signal interference, thereby enhancing its stability. SCSI-3 is preferred in this embodiment.
Step S120, determining a target physical block corresponding to the file to be sorted, where the target physical block includes the same physical block and/or a plurality of adjacent physical blocks.
In this embodiment, the target physical block is used to store the file to be sorted.
Optionally, after determining the file to be sorted, the target physical block may be determined based on the size of the data amount of the file to be sorted, where the file to be sorted is preferentially stored in the same physical block or multiple adjacent physical blocks.
Step S130, modifying the physical address corresponding to the file to be sorted into the physical address of the target physical block.
In this embodiment, modifying the physical address corresponding to the file to be sorted into the physical address of the target physical block is address optimization, and only the physical address corresponding to the file to be sorted needs to be changed, the logical address is not changed, and the server side can still read the file to be sorted stored in the terminal based on the previously stored logical address.
Optionally, referring to fig. 3A, the overall system framework involved in the file address optimization method mainly involves the following layers:
1. Upper layer application software;
2. OS file system management software and hardware communication bus;
3. a solid state storage device master control;
4、4Nand Flash。
Specifically, when the upper layer application software and the OS file system manage to read and write files, the files are operated through an API interface provided by the processor. The method for reading and writing the file is characterized by being simple and convenient, but cannot control the system to store the specified data in the specified logical address. Nevertheless, some software may do bus-level-based operations directly by calling the read-write command API provided by the OS. The read-write command is based on various communication buses such as USB, SATA, PCIE for data interaction. These commands conform to the SCSI protocol standard. The feature is that these commands explicitly mark the logical address and data length of the write. What is a logical address: the logical address is the address provided by the storage device to the Host for managing data distribution, and is transmitted when the SCSI read-write command interaction is performed. The 4Nand Flash is a storage device in the terminal of the embodiment, and generally comprises a storage control chip (namely a main control chip) and a plurality of NAND FLASH, NAND FLASH storage media used for the storage device, and has the characteristic of being difficult to lose when power is cut off. Therefore, after the master control receives the data with the designated logical address, the corresponding data is written to a specific position NAND FLASH for storage through an algorithm management called FTL. The command used at this time is NAND FLASH read/write command, and the address used is NAND FLASH address.
When software performs a file writing operation, many times, the software cannot control the address of the data writing when the software directly calls the file system API provided by the server. When some software needs to save files with larger data volume, the provided API is called to save the data, and the OS uses continuous large data transmission to save the data to continuous logic addresses at the beginning. Generally, at this time, the solid state disk also stores the data to the continuous NAND FLASH addresses after the FTL is converted due to the continuous large data command received. However, with the use of the hard disk, the hard disk is also written with a lot of small data scattered, and Garbage Collection (GC) is started when the hard disk is to be fully written. When garbage collection is performed, such continuous data is likely to be scattered due to its collection mechanism. Although the contiguous data is broken up in NAND FLASH at this time, the addresses remain contiguous as viewed from the logical address by the Host due to the FTL's logical address to NAND FLASH address mapping management.
This has a problem in that if the data is discontinuous in NAND FLASH, the read performance of the data will be affected. It is obvious that, for example, games can be significantly slowed down when they are loaded with large resources. And the operating system has no way at this time because it is continuous from a logical address, and it is not consolidated even with the defragmentation function.
Therefore, how to solve the problem of slow reading performance of a large file which is written once but stored for a long period of time is the main intention of the present embodiment.
Optionally, referring to fig. 3B, fig. 3B is a schematic flow chart of the file address optimization method in this embodiment:
1. The SCSI protocol has provisions that allow vendors to define proprietary commands themselves, in addition to public commands. The proprietary command format and usage can be fully custom, so we use custom proprietary commands here to inform the storage device to turn on and off file address optimization functions.
2. The reason why the device needs to be informed of the file address optimization to be turned on and off is that the logical addresses of file storage are not known based on the operating software at the file system level, so that the software can only record and read the logical addresses by the storage device itself by sending the read file again. After the end command is sent, the device starts the address optimization operation of the file, and the data of the logical address used by the read command sent by the system in the period is sorted to the position with continuous address in NAND FLASH by GC, namely, only the physical address corresponding to the file to be sorted needs to be changed.
3. A SCSI command communication is divided into a command transmission stage, a data transmission stage and a command state transmission stage. In the above flow chart, three private commands are included, which are:
The file address acquisition is started;
Ending the file address acquisition;
Acquiring a file address optimization state;
The two private commands, namely the file address acquisition start command and the file address acquisition end command, do not pay attention to the data transmission stage, namely any data transmission or no data transmission, and are not listed in the above figure. And the file address optimizing state is acquired, and the storage device of the terminal needs to return to the current state in the data transmission stage.
Optionally, referring to fig. 3C, another flow chart of the file address optimization method of the present embodiment is shown:
If the server can acquire the logical address of the file to be sorted, the logical address of the file to be sorted can be sorted into a table, and then the table is notified to the terminal. Therefore, the time for reading the files to be tidied once again can be saved, and the process is simplified to a certain extent.
In the technical scheme of the embodiment, the terminal is in communication connection with the server, so that when a file arrangement instruction sent by the server is received, the file to be arranged can be subjected to address optimization based on the file arrangement instruction, the server is not required to rewrite the file to be arranged, the read-write speed of the file to be arranged can be improved, and the complexity of file address optimization is reduced.
Referring to fig. 4, fig. 4 is a second embodiment of the file address optimizing method according to the present invention, based on the first embodiment, before step S110, including:
step S140, when a file reading request sent by a server is received, sending a response result allowing to read a local file to the server, so that the server sends the file sort instruction.
In this embodiment, when detecting a file reading request sent by the server, the terminal responds to the request, so that the server determines the current address of the file to be sorted by reading the local file, thereby realizing file address optimization.
In the technical scheme of the embodiment, the address of the local file is transferred to the server in a mode of allowing the server to read the local file, only the access authority is required to be controlled, the address of the local file is not required to be counted and sent to the server, and the computing power resource of the terminal is saved.
Referring to fig. 5, fig. 5 is a third embodiment of the file address optimizing method according to the present invention, and before step S120, further includes:
Step S150, executing a garbage collection instruction to form the target physical block.
In the technical solution of this embodiment, when the terminal is to move the file to be sorted to the same physical block or a plurality of adjacent physical blocks, the garbage collection operation may be performed first, so that a blank physical block is vacated, so that the file to be sorted obtains the best quality of storage space.
Referring to fig. 6, fig. 6 is a fourth embodiment of a file address optimizing method according to the present invention, based on any one of the first to third embodiments, further including:
step S210, a current address corresponding to a file to be sorted is obtained, and the file to be sorted is stored in a terminal.
Step S220, a file arrangement instruction is sent to the terminal according to the current address corresponding to the file to be arranged, so that the terminal performs address optimization on the file to be arranged according to the current address corresponding to the file to be arranged.
In the technical scheme of the embodiment, the server is in communication connection with the terminal, so that the current address corresponding to the file to be sorted can be obtained, a file sorting instruction can be sent to the terminal based on the obtained current address of the file to be sorted, file address optimization can be completed without obtaining the file of the terminal and rewriting the file, and the complexity of file address optimization is reduced.
Referring to fig. 7, fig. 7 is a fifth embodiment of a file address optimizing method according to the present invention, based on any one of the first to fourth embodiments, step S210 includes:
step S211, a file reading request is sent to the terminal, so that the terminal responds to the file reading finger request and sends a response result of allowing reading of the local file.
Step S212, when receiving a response result sent by the terminal and allowing the local file to be read, acquiring a current address corresponding to the local file of the terminal.
Step S213, determining the current address corresponding to the file to be sorted according to the current address corresponding to the local file.
In the technical scheme of the embodiment, the server can acquire the current address of the local file stored by the terminal by accessing or reading the file of the terminal, so that the address of the file to be tidied is determined based on the acquired address, the terminal only needs to respond to the file reading request of the server, and the file tidying pressure of the terminal is reduced.
Referring to fig. 8, fig. 8 is a sixth embodiment of a file address optimizing method according to the present invention, based on any one of the first to fifth embodiments, step S211 includes:
Step S2111, obtaining the reading speed of the sub-file in the local file.
In this embodiment, the above-mentioned reading speed is a time length corresponding to a reading target recorded by the server when reading any one of the local files in the terminal.
Step S2112, determining the file to be sorted in the subfiles according to the reading speed.
In this embodiment, a local file stored in a terminal with a slow reading speed is used as a file to be sorted.
Step S2113, the current address corresponding to the file to be sorted is obtained.
In the technical scheme of the embodiment, when the server reads the local file of the terminal, the server can record the reading speed of each reading target, and then define the local file stored in the terminal with low reading speed as the file to be tidied, so that the terminal tidies the file without manually defining the file to be tidied, and the file tidying efficiency is improved.
