Replication across partitioning schemes in a distributed storage system

A tangible, non-transitory, computer-readable media having instructions thereupon which, when executed by a processor, cause the processor to perform a method comprising:

• replicating data or metadata from a first storage system having a first partitioning scheme to a second storage system having a second, differing partitioning scheme;
• performing a transformation on an identifier of the data or metadata from the first storage system;
• and
• using a result of the transformation on the identifier of the data or metadata from the first storage system to map the data or metadata from the first storage system into the second partitioning scheme, in the replicating to the second storage system.

A storage system, comprising:

• storage memory;
• and
• one or more processors, configurable to:
• replicate data or metadata having a first partitioning scheme implemented to store the data or metadata according to a first plurality of partitions in the storage memory, to a second storage system having a second, differing partitioning scheme comprising a second plurality of partitions differing in number from the first plurality of partitions;
• perform a transformation on an identifier of the data or metadata from the storage system;
• and
• map the data or metadata from the storage system into the second partitioning scheme, using a result of the transformation, to replicate the data or metadata to the second storage system.
