New challenges to file systems' metadata performance are imposed by the continuously
growing number of files existing in file systems. The total amount of metadata can become …

With the growth of online services, a large amount of files have been generated by users or
by the service itself. To make it easier to service users with different network environments …

With the convergence of high-performance computing (HPC), big data and artificial
intelligence (AI), the HPC community is pushing for “triple use” systems to expedite scientific …

Distributed filesystems typically employ synchronous metadata updates, facing inherent
challenges for access efficiency, load balancing, and directory contention, especially under …

With the rapid development of the Internet of Things (IoT), the IoT is characterized by a wide
variety of data sources, large scale and heterogeneous structure. But those characteristics …

As large file systems increasingly grow in size, metadata operations become one of the
major performance bottlenecks that constrain the overall I/O performance. Previous analysis …

Exponentially growing capacities of disk drives have increased the problem that not only a
complete disk can fail, but also individual, small groups of sectors can be erroneous. These …

While an input/output (I/O) interface's syntax describes the available operations, its
semantics determines how these operations behave and which assumptions developers …

How to store masses of small files is a generally acknowledged problem in industry and
academia. Small file merging is the most successful strategy to solve this problem, which …

File systems as well as I/O libraries offer interfaces which can be used to interact with them,
albeit on different levels of abstraction. While an interface's syntax simply describes the …
