Red Hat Enterprise Linux 7 is now available for download

Abstract: There is no doubt that Linux is a popular operating system, although it is more popular in the server field than in the desktop. If you are a fan of Red Hat Enterprise Linux, the company announced today that RHEL 7 is open for download. The new version includes many changes. For system administrators, it may take some time to learn and adapt.

Evaluation version: https://access.redhat.com/site/downloads/

The biggest change is the new file system-XFS will replace ext4-mainly because XFS supports up to 500 TB while ext4 supports only 50 TB.

The performance of the XFS file system when processing a large number of small files is unknown, and administrators also need to learn how to manage it. Of course, RHEL 7 still supports ext4.

RHEL 7 is also working hard on Virtualization to support Docker ininers and promises to be able to run close to bare metal (after SELinux security control is deployed ).

This is a very useful technology similar to Solaris Zones, so we are very much looking forward to its performance in the enterprise environment. It may take some time to see whether these containers will become popular around the world.
