Abstract
Embodiments of the present disclosure relate to methods and apparatuses for data copy avoidance where after a data access request is received from the first storage node, what is sent by a second storage node to the first storage node is not an address of a second storage space in a second mirrored cache, but an address of a first storage space in a first cache corresponding to the second storage space. In this way, data access may be implemented directly in the first cache on the first storage node, and can reduce data communication across different storage nodes, eliminate potential system performance bottlenecks, and enhance data access performance.
