Abstract
A cache driver, a host bus adapter and methods used by them are provided. The method used by the cache driver includes: receiving a first I/O request for accessing data, and sending a second I/O request to a host bus adapter (HBA). The cache driver sends the second I/O request in response to determining that the first I/O request accesses hot data on a HDD. In that case, the second I/O request is a request to the HBA to send a third I/O request to both the HDD and an SSD. The method used by the HBA includes: receiving a second I/O request from a cache driver. The second I/O request is a request to the HBA to send a third I/O request to both a HDD and an SSD. The HBA then sends the third I/O request.
