Today, Red Hat announces the availability of the public Beta of Red Hat
Enterprise Linux 6.3. With this Beta, Red Hat provides early access to
the third minor release of Red Hat Enterprise Linux 6, which was
initially announced in November 2010. This minor release demonstrates
the ongoing effort of Red Hat to innovate with Red Hat Enterprise Linux
while maintaining the overall application and platform compatibility
across the life cycle. As recently announced here,
the Red Hat Enterprise Linux 6 life cycle is now extended to 10 years.
The Beta of Red Hat Enterprise Linux 6.3 showcases both enhancements and
brand new features in many areas including virtualization, scalability,
file systems, storage, security, identity management, and hardware
enablement. Although there are nearly 50 new and enhanced features in
Red Hat Enterprise Linux 6.3, here are among the most noteworthy:
* A new tool called Virt-P2V that facilitates the conversion of physical
Windows or Red Hat Enterprise Linux systems into virtual images to be
deployed as KVM guests inside Red Hat Enterprise Linux or Red Hat
* Stronger compliance with Payment Card Industry Data Security Standards
(PCI-DSS) standards, including the ability to perform secure wipes of
virtual machine disks.
* The ability to perform live volume resizing, improving overall
availability of virtualized guests.
* The maximum number of virtual CPUs (vCPUs) has been increased from 64
to 160, which lets you run larger CPU-intensive workloads on the Red Hat
Enterprise Linux platform. VMware ESX 5.0 currently supported 32 vCPUs.
* The maximum supported memory configuration for KVM guests has been
increased from 512GB to 2TB.
* GFS2 enhancements that create faster read-write capabilities for
specific use cases.
* Support of O_Direct in FUSE (Filesystem in User Space), which can
provide improved performance for certain workloads.
* Simplified configuration and administration for the file system.
Integration of automount capability with SSSD (System Security Services
Daemon) provides centralized management of configuration data and the
ability to improve performance through caching and load balancing. (This
feature is a Technology Preview.)
* Red Hat Enterprise Linux 6.3 provides full support for Fibre Channel
over Ethernet (FCoE) Target. This feature, which was previously
provided as a Technology Preview, allows customers to present their Red
Hat Enterprise Linux servers as FCoE storage devices. This feature
complements the FCoE Initiator support that was delivered in Red Hat
Enterprise Linux 6.0.
* The Logical Volume Manager (LVM) now provides support for RAID levels
4, 5, and 6. (Previously, support for these RAID levels was provided
through the MD subsystem.) This expanded LVM RAID support simplifies
overall storage administration by consolidating all management
functions, such as creating volumes, resizing volumes, deploying RAID,
taking snapshots, etc., into a single interface. (This feature is a
* The LVM now provides the ability to create thin provisioned logical
volumes. Previously, storage was allocated when the volume was created,
and needed to be monitored for space consumption and expanded manually.
In Red Hat Enterprise Linux 6.3, storage is allocated as required,
allowing volumes to expand up to the requested size on demand without
intervention. (This feature is a Technology Preview.)
* Availability of a two-factor authentication mechanism, enhancing the
overall security available to lock down Red Hat Enterprise Linux
environments and enabling compliance with industry standards such as
* Expansion of the Advanced Encryption Standard (AES) to provide
particular benefits for system performance on multi-processor machines.
* With native support for netgroups and the services map in System
Security Services Daemon (SSSD), Red Hat Enterprise Linux servers can be
integrated into centralized systems -- such as Active Directory -- to
manage system users.
* The addition of an automembership plug-in streamlines the
administration of new users and hosts when they are added into the
Identity Management system by automatically placing them into predefined
set of groups, speeding user and host provisioning.
* Performance improvements through session data caching, which lowers
the overall load on authentication servers.
* Software bandwidth management for USB 3.0 for select Intel platforms
is now available.
* Compiler optimization for Intel Xeon E5 processor family, which
improves the result of string operations, is now included.
* Improvements to memory and I/O breakpoint execution operations within
compiler tools are now included.
* With the introduction of OpenJDK 7, customers can develop and test
with the latest version of open source Java.
We look forward to our customer feedback on this beta, and to the
continued adoption of Red Hat Enterprise Linux 6, the modern operating
platform for the next generation enterprise.
