Filesystem

Revision as of 02:09, 18 February 2014

Filesystems are Electronic Formats that are a prerequisite to being able to read any file off a digital medium — you have to be able to mount the filesystem, and thus read it, in order to be able to read a file.

Single-system filesystems

(How files are organized on one system or device, such as a disk, tape, or flash memory; see next category for networked and cloud filesystems. Of course, any filesystem can be made available on a network to remote devices, but these are the native filesystems present on the storage device itself.)

• Xiafs (Linux, dropped in favour of ext2)
• XFS (SGI)
• XtreemFS, (Linux, distributed file system)
• YAFFS
• ZFS

Networked and cloud filesystems

(Used to make files available to multiple systems over a local or wide area network, including "on the cloud" via the Internet; systems access files through a protocol or API. The low-level storage details, usually concealed from end users and even most developers, may be within one or more of the single-device filesystems above, and the networked/cloud filesystem is generally defined independently of such details and might have very different characteristics and rules as to how the files are named, addressed, and structured.)

• Amazon S3
• Andrew File System (Carnegie Mellon University)
• Google Drive
• Google File System
• Hadoop Distributed File System
• MEGA file system
• NetWare File System (Novell NetWare, replaced by NSS)
• NSS (Novell Storage Services)
• OpenStack Swift
