Techniques, which provide visual representations, involve displaying, in a first display area, a plurality of first visual representations indicating a plurality of storage nodes in a storage system, the plurality of storage nodes in the storage system having data replication relations, and the data replication relations including: replication of first data at a first storage node to one or more second storage nodes, and/or replication of second data at one or more second storage nodes to the first storage node. The techniques further involve displaying, in the first display area, a plurality of second visual representations indicating a plurality of data replication relations between the plurality of storage nodes. Accordingly, respective storage nodes in the storage system in a topology view can be visualized, and data replication relations between the respective storage nodes can be clearly described.

Method, device and computer program product for providing visual representation

Systems and methods for managing data replication between data storage resources with differing capabilities. A system can check whether capabilities of a primary data storage system are different from capabilities of a secondary data storage system. Such checking can be performed based on a release version of each of the primary and secondary data storage systems. If the capabilities of the respective data storage systems are determined to be different, then the system can make a determination as to whether or not the difference can be rectified. If the difference can be rectified, such as by enabling/disabling certain features of the primary and/or secondary data storage system, then the system can perform such a rectification and proceed with provisioning of data to be replicated. If the difference cannot be rectified, then the system can prevent the provisioning of the data and notify an administrator of the data storage systems.
