Variable vs. fixed-block dedupe: A technical analysis

Examining the Effectiveness of Variable-block vs Fixed-block Deduplication on Data Reduction

Cover

While deduplication is perceived largely as a ‘checkbox’ technology for purchasers, individual implementations vary greatly in their effectiveness and in their ability to lower TCO via data reduction.

It doesn’t help that some vendors are overly creative with their measurement techniques in their attempt to generate the biggest datasheet numbers, and industry analysts shy away from direct head-to-head product comparisons.

For comparison purposes, this white paper presents a technical analysis on the effectiveness of variable-block versus fixed-block deduplication. Continue reading to see which approach provides greater data reduction for semi-structured, structured, and unstructured data.
