This book was released on 2019 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data deduplication has been widely used in various storage systems for saving storage space, I/O bandwidth, and network traffic. However, existing deduplication techniques are inadequate as they introduce significant computation and I/O cost. First, to detect duplicates the input data (files) are usually partitioned into small chunks in the chunking process.It can be very time consuming if the content-defined chunking (CDC) method is adopted, where the chunk boundaries are determined by checking the data content byte-by-byte,for detecting duplicates among modified files. Second, for each chunk generated in the chunking process, we need to apply a collision resistant hash function on it to generate a hash value (fingerprint). Chunks with the same fingerprint are deemed as having the same contents and only one copy of the data is stored on the disk. The fingerprinting process of calculating the collision-resistant hash value for each chunk is compute-intensive. Both the chunking and fingerprinting processes in existing deduplication systems introduce heavy computation burdens to the system and degrade the overall performance of the system. Third, in addition to the extra cost introduced by the chunking and fingerprinting processes, a deduplication system introduces extra I/O overheads for persisting and retrieving its metadata, which can significantly offset its advantage of saving I/O bandwidth.To this end, a deduplication system demands efficient computation and I/O operations. In this dissertation, we made several efforts to reduce the computation and I/O overheads in deduplication systems. First, two efforts have been made to accelerate the chunking process in the CDC-based deduplication. We designed a new parallel CDC algorithm that can be deployed on the SIMD platform to fully exploit its instruction-level parallelism without compromising the deduplication ratio. Further, we designed a highly efficient CDC chunking method that removes the speed barrier imposed by the existing byte-by-byte chunk boundary detection technique through exploiting the duplication history.Second, we identified an opportunity to use fast non-collision-resistant hash functions for efficient deduplication of journaled data in a journaling file system to achieve much higher file access performance without compromise of data correctness and reliability. Third, to avoid the performance degradation caused by the frequent writes of small metadata in primary deduplication systems, we proposed to opportunistically compress the fixed-size data block to make room for embedding the metadata. With the proposed method, in most cases the explicit metadata writes on the critical path can be avoided to significantly improve the I/O efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: Until now, the only way to capture, store, and effectively retain constantly growing amounts of enterprise data was to add more disk space to the storage infrastructure, an approach that can quickly become cost-prohibitive as information volumes continue to grow and capital budgets for infrastructure do not. In this IBM® Redbooks® publication, we introduce data deduplication, which has emerged as a key technology in dramatically reducing the amount of, and therefore the cost associated with storing, large amounts of data. Deduplication is the art of intelligently reducing storage needs through the elimination of redundant data so that only one instance of a data set is actually stored. Deduplication reduces data an order of magnitude better than common data compression techniques. IBM has the broadest portfolio of deduplication solutions in the industry, giving us the freedom to solve customer issues with the most effective technology. Whether it is source or target, inline or post, hardware or software, disk or tape, IBM has a solution with the technology that best solves the problem.
