<b><font face="ARIAL NARROW,HELVETICA">XFS Beta Release</font></b></h2>

<p>
On September 22, SGI released the beta version of its high-end XFS file
system ported to Linux®. As a leading supporter of Linux and the open source
movement, SGI is providing business-critical infrastructure for Linux
through porting such solid and high-performance software as XFS to Linux and
making it available to the community.
</p>

<p>
Existing file systems for Linux entail significant limitations in
scalability and stability. Unlike other journaled file systems currently
under development, XFS is a mature technology that has been proven on
thousands of IRIX systems for over six years. It is widely recognized as the
industry's leading high-performance file system. SGI has now optimized XFS
for Linux users, providing the same flexible, high-capacity, and reliable
file system as before. Features such as instantaneous recovery from disk
crashes and the ability to support extremely large disk farms will establish
XFS as the production quality file system for Linux. Furthermore, porting
XFS to Linux is helping advance some of the Linux kernel infrastructure such
as the VM subsystem and the block device interface.
