We are pleased to announce the beta release of Red Hat Enterprise Linux

Hat Enterprise Linux 6.6 Beta includes enhancements to both security and 
stability as well as:

  * Increased system performance
  * An improved system administration experience
  * Enhancements to Red Hat Enterprise Linux as a virtual guest

Red Hat Enterprise Linux 6 offers a stable, proven, and predictable 
platform, balancing the enterprise need to maintain a reliable and 
secure platform for mission critical workloads with the flexibility to 
adapt to changing business needs. Red Hat Enterprise Linux 6.6 Beta 
continues to answer this need, providing enhanced functionality that 
allows organizations to easily build and manage large, complex IT 
infrastructure for deployment across physical, virtual, and cloud 
environments.

Red Hat Enterprise Linux 6.6 Beta delivers a variety of improvements 
that provide increased system performance across physical, virtual, and 
cloud environments. These optimizations and tuning improvements include:

  * Out-of-the-box support for Remote Direct Memory Access (RDMA) over 
Converged Ethernet (RoCE) to deliver low-latency, high bandwidth network 
connectivity
  * A new socket polling implementation that reduces network latency and 
jitter
  * Kernel locking improvements to allow for increased CPU utilization 
on large systems
  * Support for additional 40GbE network adapters

Organizations that build large, complex environments will benefit from 
enhancements that provide a better system administration experience. 
These include:

  * Full support for load balancer technology like HAproxy and keepalived
  * Improved manageability of resource lists in large, high availability 
configurations
  * The addition of Performance Co-Pilot (PCP), a framework and set of 
services supporting system level performance monitoring and management 
in distributed environments

Red Hat Enterprise Linux 6.6 Beta also provides enhancements to running 
Red Hat Enterprise Linux 6 as a virtual guest, upholding Red Hat’s 
commitment to refining the overall virtualization experience. 
Virtualization updates in Red Hat Enterprise Linux 6.6 Beta include 
support for a host to feed randomness to a virtual machine, increasing 
security for cryptographic applications, multi-queue performance 
improvements for guest network and storage throughput when running Red 
Hat Enterprise Linux 6.6 Beta on a Red Hat Enterprise Linux 7 host, and 
more.
