Abstract:
Embodiments of the present disclosure provide a method for establishing a multi-tier flash cache using spare drives. In some embodiments, there is provided a computer-implemented method, comprising: in response to receiving an I/O request, determining whether there is a free page in a main cache; in response to determining that there is no free page in the main cache, establishing a secondary cache by selecting at least one spare drive from spare drives; flushing data from a cold page in the main cache to the secondary cache, an access frequency of the cold page being lower than a predetermined threshold; and writing data related to the I/O request from a persistent storage device to the cold page.

Claim (Index 9):
An electronic apparatus, comprising:\n at least one processor; and a memory coupled to the at least one processor and comprising instructions stored thereon, wherein the instructions, when executed by the at least one processor, cause the apparatus to perform acts including: in response to receiving an I/O request, determining whether there is a free page in a main cache of cache; in response to determining that there is no free page in the main cache, establishing a secondary cache by selecting at least one spare drive from spare drives in a storage pool; flushing data from a cold page in the main cache to the secondary cache, an access frequency of the cold page being lower than a predetermined threshold; and writing data related to the I/O request from a persistent storage device to the cold page.
