Combined data and checksum i/o operations for storage efficiency
The patent US12073117B2 describes a sophisticated storage system that enhances data access efficiency through a multi-layered storage stack. This system comprises a storage device connected to a storage stack, which includes a file system layer, an intermediary layer, and a storage layer. The innovative approach allows the system to receive multiple input/output (I/O) operations targeting both data blocks and their corresponding checksum blocks. The file system layer processes these I/O operations, combining them into intermediary operations before the storage layer consolidates them into a single combined I/O operation. This operation is then transmitted to the underlying storage device layer, facilitating access to the specified data and checksum blocks.
Additionally, the patent outlines various configurations for optimizing I/O operations. The storage stack can determine if data blocks are dis-contiguous and combine operations accordingly. It can also adjust the rate of I/O operations based on the speed of transmission to the underlying storage device layer, allowing for efficient handling of incoming requests. The system is designed to accumulate I/O operations during a delay, enabling the combination of multiple operations into a single request, which can improve performance. Furthermore, the patent includes provisions for generating responses to the combined I/O operations, ensuring that the file system layer receives the necessary feedback for each operation. Overall, this patent presents a method and system aimed at improving the efficiency and speed of data access in storage devices.
