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 ...
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.
The server component of Distributed File System was first introduced as an add-on to Windows NT 4.0 Server, called "DFS 4.1", [5] and was later included as a standard component of all editions of Windows 2000 Server. Client-side support is included in Windows NT 4.0 and later versions of Windows.
A FAT12 and FAT16 (and FAT32) extension to support automatic file distribution across nodes with extra attributes like local, mirror on update, mirror on close, compound on update, compound on close in IBM 4680 OS and Toshiba 4690 OS. The distribution attributes are stored on a file-by-file basis in special entries in the directory table. [21] [22]
The client mounts the Lustre filesystem locally with a VFS driver for the Linux kernel that connects the client to the server(s). Upon initial mount, the client is provided a File Identifier (FID) for the root directory of the mountpoint. When the client accesses a file, it performs a filename lookup on the MDS. When the MDS filename lookup is ...
Early Unix filesystems were referred to simply as FS.FS only included the boot block, superblock, a clump of inodes, and the data blocks.This worked well for the small disks early Unixes were designed for, but as technology advanced and disks grew larger, moving the head back and forth between the clump of inodes and the data blocks they referred to caused thrashing.
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.
