The file system metadata service is the scalability bottleneck for many of today’s workloads. Common approaches for attacking this “metadata scaling wall” include: caching inodes on clients and servers, caching parent inodes for path traversal, and …
HPC and data center scale application developers are abandoning POSIX IO because file system metadata synchronization and serialization overheads of providing strong consistency and durability are too costly -- and often unnecessary -- for their …
Migrating resources is a useful tool for balancing load in a distributed system, but it is difficult to determine when to move resources, where to move resources, and how much of them to move. We look at resource migration for file system metadata …
File system metadata management has become a bottleneck for many data-intensive applications that rely on high-performance file systems. Part of the bottleneck is due to the limitations of an almost 50-year-old interface standard with metadata …
