    Abstract: The present disclosure provides a method for allocating memory, computer device and storage medium. The method can achieve allocation of hard disk memory to a target application through use of free memory information of the hard disk memory and size information written into a first storage space. In addition, the free memory information of the hard disk memory is stored in system memory, and during allocation for the hard disk memory, the free memory information of the hard disk memory is directly read from the system memory.

    Abstract: A computing device for verifying data integrity is provided, comprising a memory controller configured to receive a plurality of original data blocks. Each original data block has an associated initial CRC value. The memory controller then segments and recombines the received data blocks into logic blocks, and calculates a new logic block CRC value for each logic block. The logic blocks are transmitted with their respective new logic block CRC values to a storage device, and the logic blocks are written to non-volatile memory of the storage device in a write operation. After the write operation, a combined CRC value is calculated for the logic blocks and a combined CRC value for the original data blocks, and compare the combined CRC values. The memory controller determines whether the combined CRC values match. When they match, the memory controller generates a verification response verifying the integrity of the write operation.

    Abstract: Described are examples for storing data on a storage device, including storing, in a live write stream cache, one or more logical blocks (LBs) corresponding to a data segment, writing, for each LB in the data segment, a cache element of a cache entry that points to the LB in the live write stream cache, where the cache entry includes multiple cache elements corresponding to the multiple LBs of the data segment, writing, for the cache entry, a table entry in a mapping table that points to the cache entry, and when a storage policy is triggered for the cache entry, writing the multiple LBs, pointed to by each cache element of the cache entry, to a stream for storing as contiguous LBs on the storage device, and updating the table entry to point to a physical address of a first LB of the contiguous LBs on the storage device.

    Abstract: Described are examples for storing, in a first zone cache, one or more logical blocks (LBs) corresponding to a data chunk, writing, for each LB in the data chunk, a cache element of a cache entry that points to the LB in the first zone cache, where the cache entry includes multiple cache elements corresponding to the multiple LBs of the data chunk, writing, for the cache entry, a table entry in a mapping table that points to the cache entry, and when a storage policy is triggered for the cache entry, writing the multiple LBs, pointed to by each cache element of the cache entry, as contiguous LBs in an isolation block for the data chunk in a second zone stream, and updating the table entry to point to the isolation block in the second zone stream.
