Embodiments of the present disclosure relate to methods and apparatus for flushing pages from a solid-state storage device. Specifically, the present disclosure discloses a method of flushing pages from a solid-state storage device including determining a first number based on a period length of a flush cycle and a period length required to construct a flush transaction, the first number indicating that in the flush cycle a maximum number of flush transactions that can be constructed; and flushing pages from the solid-state storage device up to the first number during a flush cycle. The present disclosure also discloses an apparatus for flushing pages from a solid state storage device and a computer program product for performing the steps of a method for flushing pages from a solid state storage device.
Description
technical field [0001] Embodiments of the present disclosure relate generally to storage technologies, and more particularly, to methods and apparatus for flushing pages from solid-state storage devices. Background technique [0002] In storage technology, multi-layer cache stack technology has been used. In the multi-layer cache stack technology, a solid-state storage device, that is, a solid storage disk (solid storage disk, SSD) is used. During the application of the multi-layer cache stack technology, it is sometimes necessary to perform an operation of flushing pages from the solid-state storage device to the hard disk. However, in the prior art, when the operation of flushing pages from the solid-state storage device to the hard disk is performed, there are problems such as low throughput of the flushing process, which affects the efficiency of applying the multi-layer cache stack technology, and may Bring users a bad user experience.
