COPYRIGHT © 2018 | INFO@EXCELERO.COM | WWW.EXCELERO.COM WHITE PAPER ACHIEVING EFFICIENT AND SCALABLE DISTRIBUTED ERASURE CODING WITHOUT THE PERFORMANCE PENALTY Storage capacity and performance requirements are higher than ever. The flash revolution enables meeting both requirements without increasing, in most cases even decreasing, the storage footprint. This makes individual drives even more valuable as they store more and more data, which requires protection. Data protection can be achieved through replication or erasure coding. Both methods have their benefits and costs: mirroring has virtually no impact on performance but there is a higher cost as each copy requires more capacity. The cost/capaci- ty calculation is very straightforward: you choose the required level of prot
