The new RHEL is out and ready for deployment.

A day after Red Hat announced great earnings, the billion-dollar Linux company announced the global availability of the next version of its Red Hat Enterprise Linux (RHEL) operating system, RHEL 6.3.

While not a major release, RHEL 6.3 does include enhancements to take advantage of the most recent advancement from hardware originial equipment manufacturers (OEMs). This includes updated device drivers for a multitude of peripherals, and also various features like compiler optimization for the Intel Xeon E5 processor family.

It also includes the following new features:

Developer Tools: The new RHEL supports OpenJDK 7. This is the Oracle-approved open-source Java Standard Edition (SE).

Virtualization: New Virt-P2V tools that can be used to convert a RHEL or Microsoft Windows system running on physical hardware to run as Kernel Virtual Machine (KVM) guests.

Security: Users can now use two-factor authentication for securely accessing RHEL. It also includes advanced encryption capabilities so data blocks can be encrypted in parallel by taking advantage of underlying multi-processor capabilities. This is supported by the introduction of AES-CTR (Advanced Encryption Standard Counter Mode) cipher for OpenSSH, the secure connection network tool

Scalability: RHEL can now support up to 150 virtual CPUs (vCPUs) per guest. By comparison, Red Hat states that is “significantly higher than the 32 vCPU per guest limit for VMware ESX 5.0.” In addition KVM virtual machine operating systems guests can access up to 2 terabytes of RAM.

Storage: RHEL;s Logical Volume Manager (LVM) now provides support for RAID levels 4, 5, and 6 to simplify overall storage administration by consolidating all management functions, such as creating and re-sizing volumes, deploying RAID, and taking snapshots into a single interface.

You can also now deploy RHEL as a Fibre Channel over Ethernet (FCoE) istorage target server. Red Hat claims that this will provide higher levels of reliability and performance that you get with native Fibre Channel but at a significantly lower cost.

Taken as a whole, there's nothing that jumps out at you, but the over-all message is that RHEL is better than ever not just as a high-end server operating system, but as a platform for virtual machines as well. If you need a top of the line server, RHEL is continuing to give you reasons to give it serious consideration.

  • Red Hat Enterprise Linux 6.3 is ready today

    Kudos Red Hat
  • This would be great if...

    This would be great if they provided extended trial versions of the system for the people who would like to try it for awhile.
    • Why not ScientificLinux or CentOS?

      You can use the technology (sans RedHat's excellent support and artwork) for as long as you like. Great for trials and education.

    • Options:

      If you don't mind a delay you can always wait for Scientific Linux or CentOS. If you've got the skills and resources you can always grab their source RPMs off of their ftp site and build the newest update yourself.
    • RE: This would be great if...

      Why is Red Hat's 30-day evaluation period too short? What do you need to trial for a duration of more than 30 days?

      Perhaps, call a Red Hat sales rep and request an extended evaluation period? Just be prepared for them to inquire as to why you need it.

  • Yawn

    Not quite as un-exciting as Windows 8, but darned close
    • Stop yawning so loud

      SJVN's coverage of anything Microsoft, even within the body of an otherwise Linux- and Open-Source-related article, generates lots of clicks (and comments).

      When he blogs in the style (informing rather than inflaming) of ZDNet's Paula Rooney, the silence is usually deafening.
