The physical architectures of information storage systems often dictate how information is
encoded, databases are organized, and files are accessed. Here we show that a simple …

Deduplicating in-line data on primary storage is hampered by the disk bottleneck problem,
an issue which results from the need to keep an index map** portions of data to hash …

Many modern storage systems adopt erasure coding to provide data availability guarantees
with low redundancy. Log-based storage is often used to append new data rather than …

Between the two fundamental digital preservation strategies, migration has been strongly
favored. Recent developments in emulation frameworks make it possible to deliver …

Erasure coding has received considerable attentions due to the better tradeoff between the
space efficiency and reliability. The frequent update of the stored data in the distributed …

Despite domain-specific digital archives are growing in number and size, there is a lack of
studies describing their architectures and runtime characteristics. This paper investigates the …

Although user access patterns on the live web are well-understood, there has been no
corresponding study of how users, both humans and robots, access web archives. Based on …

DNA storage is one of the most promising ways for future information storage due to its high
data storage density, durable storage time and low maintenance cost. However, errors are …

Erasure coding has received considerable attention due to the better tradeoff between the
space efficiency and reliability. However, it consumes large network traffic and long time to …

Parallel application I/O performance often does not meet user expectations. Additionally,
slight access pattern modifications may lead to significant changes in performance due to …
