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.
