Abstract
Techniques for preserving locality of storage accesses to copies of storage objects in a cluster of appliances. Mapping metadata is created indicating regions in a copy of a storage object that are mapped to local storage allocated from a target appliance. Read and write operations to regions of the copy that are mapped to storage in the target appliance are processed within the target appliance. Write operations to regions that are not mapped to storage in the target appliance cause storage to be allocated to the copy in the target appliance, mapped to the regions indicated by the write operations, and used to store the write data. Read operations to regions that are not mapped to storage in the target appliance are performed on an original storage object located on a source appliance, from which the copy of the storage object was made.
