Abstract: The present disclosure provides systems and methods that relate to storing encoded information in, and reading the encoded information from, nucleotide sequences. An example method includes receiving, at a DNA readout system, a nucleotide sequence. The method also includes reading the nucleotide sequence based on an alphabet consisting of {adenine (A), cytosine (C), guanine (G), and thymine (T)}. The method further includes determining positions of unique markers between a plurality of encoded blocks in the nucleotide sequence. The method yet further includes decoding each encoded block of the plurality of encoded blocks according to an inner code, so as to form a plurality of decoded blocks. The method also includes appending the decoded blocks to one another to provide a decoded message with message length n bits.

Abstract: Systems and methods which implement forward checking of data integrity are disclosed. A storage system of embodiments may, for example, comprise data integrity forward checking logic which is operable to perform forward checking of data integrity in real-time or near real-time to check that a number of node failures can be tolerated without loss of data. Embodiments may be utilized to provide assurance that a number of fragments needed for source data recovery will be available for the source objects most susceptible to failure when a certain number of additional fragments are lost, such as due to storage node failures.
