Self-* Storage Systems




Human administration of storage systems is a large and growing issue in modern IT infrastructures. We are exploring new storage architectures that integrate automated management functions and simplify the human administrative task. Self-* storage systems are self-configuring, self-organizing, self-tuning, self-healing, self-managing systems of storage bricks. Borrowing organizational ideas from corporate structure and technologies from AI and control systems, self-* storage should simplify storage administration, reduce system cost, increase system robustness, and simplify system construction.
___
1pronounced "self-star", the name is a play on the UNIX shell wildcard character, '*'. It captures many recent buzzwords in a single meta-buzzword.
