Abstract: Methods and systems for a storage server are provided. One method includes storing data at a first storage tier by a processor executable storage operating system; tracking the data stored at the first storage tier for moving the data to a second storage tier; transferring the data from the first storage tier to the second storage tier; and updating a data structure that tracks a transfer block number of a block that stores the data, where the transfer block number is based on a virtual identifier, a generation count and an offset value of a storage chunk that is a portion of a physical volume block number address space.

Abstract: Methods and systems for a networked system are provided. One method includes receiving a request by a processor to transfer a data block stored at a first storage tier to the second storage tier; using an object staging data structure to determine that an object is available for transferring the data block from the first storage tier to the second storage tier. The object staging data structure an indicator providing a status for the object and an object length and an offset value of a transfer log indicating where information regarding the data block is stored. The method further includes updating an address of the storage tier where the information regarding data block is stored at the transfer log; increasing the object length and the offset value at the object staging data structure; and creating the object at the second tier.

Abstract: Methods and systems for a networked storage environment are provided. One method includes scanning a first data structure by a processor executing instructions out of a memory for a storage operating system to determine whether any data chunk of a first object stored at a first storage tier is referenced by the storage operating; when the storage operating system references a certain number of data chunks, the processor using an object staging data structure to identify a second object that is in the process of being built with space for transferring the certain number of data chunks from the first object to the second object; and updating information regarding the second object at a transfer log with location information of the certain number of data chunks at the first storage tier.
