1. A computer-implemented method for layered storage of enterprise data, said method comprising:

  • receiving from one or more virtual machines data blocks having a fixed length block size in the range from 4 kilobyte to 64 kilobyte;

    de-duplicating said data blocks per hypervisor serving one or more of said virtual machines;

    storing de-duplicated data blocks in a local cache memory of a storage accelerator;

    time-based grouping said data blocks into data containers having a configurable maximum container size in the range from 1 megabyte to 16 megabyte;

    dividing each data container in X fixed length mega-blocks, X being a first integer number;

    for each data container applying erasure encoding to said X fixed length mega-blocks to thereby generate Y fixed length mega-blocks with redundant data, Y being a second integer number larger than X; and

    distributed storing said Y fixed length mega-blocks over multiple backend storage systems.
