Abstract
Embodiments of the present disclosure provide methods, apparatuses and computer program products for managing a storage system. The storage system comprises a plurality of cache devices and a bottom storage device, and the plurality of cache devices comprise a first cache device group and a second cache device group. The method according to an aspect of the present disclosure comprises: receiving an input/output (I/O) request for the storage device; in response to determining that the I/O request triggers caching of target data, storing the target data from the storage device into the first cache device group if the I/O request is a read request; and storing the target data into the second cache device group if the I/O request is a write request.
