  • Patent number: 10114832
    Abstract: 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.

  • Publication number: 20180309815
    Abstract: 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.

  • Patent number: 6763476
    Abstract: A system and method using a timer management module for managing a circular queue having N Fixed Timer Entries (FTEs) to enable dynamic capacity increase of size M by extending the pointer array referencing the circular queue by M, copying the first “Current Timer Index” entries to the extended pointer array entries, allocating M FTEs, and linking the M FTEs within the circular queue.

  • Patent number: 6714959
    Abstract: A circular queue is created with N Fixed Timer Entries associated with a specific address pointer for each entry. An association is developed to relate each fixed entry pointer to its just previous pointer and to its just next occurring pointer. A selected transient New Timer Entry can be inserted between any two selected adjacent Fixed Timer Entries without need to sequence serially through the entire set of fixed entries.
