The XFS guaranteed-rate I/O system provides an API that allows applications to reserve bandwidth to the filesystem. XFS dynamically calculates the performance available from the underlying storage devices, and will reserve bandwidth sufficient to meet the requested performance for a specified time. This is a feature unique to the XFS file system.
J/XFS is an alternative API to CEN/XFS (which is Windows specific) and also to Xpeak (which is Operating System independent, based on XML messages). J/XFS is written in Java with the objective to provide a platform agnostic client-server architecture for financial applications, especially peripheral devices used in the financial industry such ...
The VERITAS File System (or VxFS; called JFS and OnlineJFS in HP-UX) is an extent-based file system.It was originally developed by VERITAS Software. [1] Through an OEM agreement, VxFS is used as the primary filesystem of the HP-UX operating system.

Unionfs is a filesystem service for Linux, FreeBSD and NetBSD which implements a union mount for other file systems.It allows files and directories of separate file systems, known as branches, to be transparently overlaid, forming a single coherent file system.
All of the Linux filesystem drivers support all three FAT types, namely FAT12, FAT16 and FAT32.Where they differ is in the provision of support for long filenames, beyond the 8.3 filename structure of the original FAT filesystem format, and in the provision of Unix file semantics that do not exist as standard in the FAT filesystem format such as file permissions.

Defragmentation, shrinking, and rebalancing operations require extents to be relocated. However, doing a simple copy-on-write of the relocating extent will break sharing between snapshots and consume disk space. To preserve sharing, an update-and-swap algorithm is used, with a special relocation tree serving as scratch space for affected ...
Note that in addition to the below table, block capabilities can be implemented below the file system layer in Linux (LVM, integritysetup, cryptsetup) or Windows (Volume Shadow Copy Service, SECURITY), etc.
