PARTIAL SUCCESSFUL DATA DELIVERY IN A DATA STORAGE SYSTEM

摘要

In response to receiving a data storage access request from a host system, a controller of a data storage system communicates first data of the data storage access request with the host system via a communication link. The controller determines whether communication of the first data via the communication link passes a data integrity check. In response to determining that communication of the first data via the communication link passes the data integrity check, the controller transfers second data between a storage device of the data storage system and the host system, determines whether transfer of the second data between the storage device and host system is only partially successful, and in response to the controller determining that transfer of the second data between the storage device and host system is only partially successful, requests retransmission of only a subset of the second data that was not successfully transmitted.
