摘要:
A method for improving performance in a storage system is provided. The method comprises receiving a request to destage a partial stride of data from a storage cache; reserving space for a full stride of data on one or more storage devices; allocating the partial stride of data to the reserved space; adding padding for unallocated blocks, wherein the unallocated blocks are reserved for future updates; and destaging the full stride of data to the storage devices, wherein the full stride of data comprises the allocated partial stride of data and the padded unallocated blocks.
