Data stream generation using prime numbers is disclosed, including: receiving an initialization parameter; and using the initialization parameter to generate a data stream comprising a merging of a first sequence and a second sequence, wherein the first sequence is generated using a first prime number and the initialization parameter and the second sequence is generated using a second prime number and the initialization parameter.

Data stream generation using prime numbers

Generating a data stream with a predictable change rate is disclosed, including: receiving a change rate parameter; and using the change rate parameter to provide a modified data stream that differs from a corresponding unmodified non-deduplicatable data stream by an amount determined based at least in part on the change rate parameter, including by: modifying at least a portion of a plurality of data blocks associated with the non-deduplicatable data stream to obtain a corresponding portion of the modified data stream, wherein a data block of the plurality of data blocks is associated with a block size that is based on a segmenting attribute associated with a storage destination.

Generating a data stream with a predictable change rate

Generating non-compressible data streams is disclosed, including: receiving an initialization parameter; determining at least one constrained prime number; generating a sequence comprising a plurality of byte values based at least in part on the initialization parameter and the constrained prime number; determining a rotation value; and rotating a portion of the sequence based on a rotation value to form a rotated sequence, wherein the rotated sequence comprises byte values substantially defeating a predictive compression algorithm.

Rotating bit values while generating a large, non-compressible data stream

Generating non-compressible data streams is disclosed, including: receiving an initialization parameter; determining a constrained prime number, wherein the constrained prime number comprises a plurality of component values, wherein each of the plurality of component values comprises a prime number, wherein each of the plurality of component values is different; and generating a non-compressible sequence based at least in part on the initialization parameter and the constrained prime number.

Generating a large, non-compressible data stream

Generating non-compressible data streams is disclosed, including: receiving a sequence comprising a plurality of byte values calculated from an initialization parameter and a constrained prime number; determining a data structure index from a plurality of bits within at least one of the plurality of byte values; retrieving a rotation value from a data structure, wherein the rotation value is stored in the data structure at the data structure index; and rotating a portion of the sequence based on a rotation value to form a rotated sequence, wherein the rotated sequence comprises byte values substantially defeating a predictive compression algorithm.

Rotating bit values based on a data structure while generating a large, non-compressible data stream

A data storage system comprising a plurality of storage nodes. Data storage mechanisms are implemented in each storage node communicating a storage request to at least one storage node. The at least one storage node implements the storage request using an arbitrary subset of the storage nodes.
