 XFS is a high-performance file system which was designed by SGI for their IRIX platform. Since
XFS was ported to the Linux kernel in 2001, XFS has remained a preferred choice for many
enterprise systems especially with massive amount of data, due to its high performance, architectural
scalability and robustness.
 The XFS file system is an extension of the extent file system.
 XFS is a high performance 64-bit journaling file system.
 Support of XFS was merged into the linux kernel in around 2002 and In 2009 Red Hat Enterprise
Linux version 5.4 usage of XFS file system.
 Now RHEL 7.0 uses XFS as the default file system.
 XFS supports maximum file system size of 8 exbibytes for 64bit file system.
 Some comparison of XFS file system is XFS file system cannot be shrunk and poor performance with
deletions of large numbers of files.
 32-bit system 64-bit system
 File size: 16 Terabytes 16 Exabytes
 File system: 16 Terabytes 18 Exabytes
 Drawback: XFS file system cannot be shrunk and poor performance with deletion of the large
numbers of files.
