Methods and systems for efficiently storing data at a plurality of storage tiers using a transfer data structure
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.
