Abstract: Systems and methods of maintaining a policy implementation for an object across different storage systems are disclosed. The method includes determining, for an object to be copied from a first storage system, one or more object policies that are applicable to the object; generating metadata that triggers application of the one or more policies at an other storage system that is different from the first storage system; and including the metadata with the object during copying of the object.

Abstract: A non-volatile solid-state storage is provided. The non-volatile solid state storage includes a non-volatile random access memory (NVRAM) addressable by a processor external to the non-volatile solid state storage. The NVRAM is configured to store user data and metadata relating to the user data. The non-volatile solid state storage includes a flash memory addressable by the processor. The flash memory is configured to store the user data responsive to the processor directing transfer of the user data from the NVRAM to the flash memory.
