MIGRATING ENCODED DATA SLICES FROM A RE-PROVISIONED MEMORY DEVICE OF A DISPERSED STORAGE NETWORK MEMORY

摘要

A method begins by maintaining a memory assignment table for memory devices within the storage unit. The memory assignment table includes a field for memory identifier, a field for memory allocation, and a field for memory usability status. The method continues by utilizing the memory assignment table to perform one or more functions. One function includes selecting a first memory device to store incoming data. Another function includes determining when to decommission a second memory device based on memory usability status of the second memory device. A further function includes determining when to migrate data stored on a third memory device to another memory device. A still further function includes changing a storage protocol of data stored on a fourth memory device.
