Embodiment Construction
[0042] The core of the present invention is to provide a method, system and device for managing data blocks in SSD firmware. During the process of performing operations on data blocks in SSD, if the data blocks are unstable, the unstable data blocks will be The data in the SSD is moved to a stable data block to continue the operation, thereby ensuring the integrity and correctness of the data in the SSD and improving the performance of the storage system.
[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of...

The invention discloses a method, system and device for managing data blocks in SSD firmware, including: when determining that there is an unstable block in the SSD, judging whether the unstable block is an open block; if so, closing the open block operation, and correspondingly open a stable and unused block, and move the data in the open block to the unused block to successfully complete the data transfer process; if not, directly perform data transfer processing on the closed block that meets the conditions . It can be seen that in the present application, when the data block in the SSD is performing an operation, if the data block is unstable, the data in the unstable data block will be moved to a stable data block to continue the operation, thereby ensuring The integrity and correctness of the data in the SSD improves the performance of the storage system.
Description
technical field [0001] The present invention relates to the field of storage technologies, in particular to a method, system and device for managing data blocks in SSD firmware. Background technique [0002] With the development and wide application of technologies such as the Internet and cloud computing, computer systems will generate massive amounts of data during use, and these massive amounts of data need to be processed and stored, thus putting forward higher requirements for the performance of the storage system . In the prior art, SSDs (Solid State Drives, solid state drives) are widely used in storage systems due to their fast read and write speeds and low energy consumption. It can be seen that the integrity and correctness of data stored in SSDs have a great impact on the performance of storage systems. very important. However, when the data blocks in the SSD are being operated, the data blocks may become unstable. If the operation continues on the unstable data...
