XFS: SGI's extended file system goes open source

XFS will be fundamental in transforming Linux into a serious server at the enterprise level. As a fileserver, Linux currently performs poorly: ext2 yields only mediocre transaction times; file system recovery and repair is awesomely slow; failure tolerance is almost non-existent; and the architecture allows for a maximum file size of a mere 2GB.

The proven technology of XFS under IRIX, combined with SGI's background in the high-end computing market and commitment to open source development, should work to overcome these restraints and remove many of the criticisms that Linux cannot perform at the enterprise level. As SGI itself puts it: "SGI plans to help Linux mature into a world-class, robust, reliable, feature-rich, widely used, and enterprise-ready operating system." (http://oss.sgi.com/projects/xfs/papers/xfs_GPL.pdf)This intention indicates that SGI's support of the Linux open source movement will not stop with this single file system, but rather that it will bring other applications, technical expertise and experience to Linux development and the community at large.

Moreover, XFS running under Linux will mean that enterprise-level file servers currently using XFS will have no problem moving into a Linux environment, where the other features of Linux can also be enjoyed. XFS will complement the scalability found elsewhere in Linux. Most large file systems currently in use within the industry stand at around 1TB; XFS can work with a file system millions of times this size. With disk sizes increasing exponentially year by year, such a file system will differentiate Linux from the rest.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre x360

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
