Abstract: Techniques are provided for a layout format for compressed data. A first set of data blocks are grouped into a first group based upon a first frequency of access to the first set of data blocks. A second set of data blocks are grouped into a second group based upon a second frequency of access to the second set of data blocks. The first set of data blocks are compressed into a first compression group using a first compression algorithm. The second set of data blocks are compressed into a second compression group using a second compression algorithm.

Abstract: Methods and systems for a storage environment are provided. One method includes identifying, by a processor, a plurality of block numbers of a fragmented address space for re-allocation, each block number associated with data stored by a file system in a storage device of a storage system; determining, by the processor, compressed data associated with a block number from among the plurality of block numbers; verifying, by the processor, that an indirect block of a hierarchical structure maintained by the file system references the block number associated with the compressed data; and copying, by the processor, the compressed data to a new block, without decompressing the data.
