A method for a storage network computing device includes receiving a request to store a data object and generating a plurality of write slice requests, where the plurality of write slice requests includes a set of encoded data slices to be stored in the storage network and at least a decode threshold number of encoded data slices of the set of encoded data slices is required to recover a corresponding portion of a data object. The method continues by identifying a set of storage devices (from a plurality) for storage of the set of encoded data slices, where the plurality of storage devices includes one or more first memory devices local to the computing device and one or more second memory devices that are remote from the computing device. The method then continues, by storing the set of encoded data slices in the identified set of storage devices, generating a set of write slice responses relating to the set of encoded data slices and outputting the set of write slice responses.

Virtualization in a dispersed storage network utilizing local and remote memory

A method for execution by a dispersed storage and task (DST) client module includes obtaining a data identifier for slice location identification. A source name corresponding to the data identifier is identified. A plurality of data segments are identified based on the source name. A set of slice names are generated for each of the plurality of data segments. A set of DST execution units are identified based on the sets of slice names. A set of query requests are generated for each data segment for transmission to the set of DST execution units. Query responses are received from the set of DST execution units. A storage record is generated that includes storage location information of the query responses. Migration of at least some encoded data slices associated with the sets of slice names is facilitated when the storage record compares unfavorably to a storage record requirement.
