Abstract

Techniques are provided for combining data block and checksum block I/O into a single I/O operation. Many storage systems utilize checksums to verify the integrity of data blocks stored within storage devices managed by a storage stack. However, when a storage system reads a data block from a storage device, a corresponding checksum must also be read to verify integrity of the data in the data block. This results in increased latency because two read operations are being processed through the storage stack and are being executed upon the storage device. To reduce this latency and improve I/O operations per second, a single combined I/O operation corresponding to a contiguous range of blocks including the data block and the checksum block is processed through the storage stack instead of two separate I/O operations. Additionally, I/O operation may be combined into a single request that is executed upon the storage device.
