The integrity of transmitted data can be protected by causing that data to be transmitted twice, and calculating protection information (PI) for the data from each transmission. The PI can include information such as a checksum or signature that should have the same value if the data from each transmission is the same. If the PI values are not the same, an error handling procedure can be activated, such as may retry the transmission. For write operations, the data can be transmitted twice from a source to a storage destination, while for read operations, the data can be transmitted to a recipient then sent back from the recipient to the storage device, with PI calculated for each transmission. A component such as a storage processor can perform at least this comparison step. Such approaches can also be used for network transmission or high performance computing.
