The Red Hat Enterprise Linux team is pleased to announce the release of 
Red Hat Enterprise Linux 6.6, the latest version of our Red Hat 
Enterprise Linux 6 platform. With the release of Red Hat Enterprise 
Linux 6.6, we continue to refine the stable and secure Red Hat 
Enterprise Linux 6 platform which provides a reliable foundation for 
mission-critical systems across industries and regions.

Whether you’re operating on bare metal, building out a virtual 
infrastructure, or leveraging the open hybrid cloud, Red Hat Enterprise 
Linux 6, with enhancements to virtualization, performance and system 
administration, continues to be an excellent choice for deploying and 
managing large and complex IT projects.

Red Hat Enterprise Linux 6.6 delivers a variety of improvements that 
provide increased system performance across physical, virtual, and cloud 
environments. These optimizations and tuning improvements include:
   * Kernel locking improvements to allow for more efficient CPU 
utilization on large NUMA systems
   * Out-of-the-box support for Remote Direct Memory Access (RDMA) over 
Converged Ethernet (RoCE) to deliver low-latency, high bandwidth network 
connectivity; functionality that was previously delivered through the 
High Performance Networking Add-on
   * A new optional socket polling implementation (“busy-poll”) that 
reduces network latency and jitter
   * Support for additional 40GbE network adapters (i.e. Solarflare, 
Intel, Emulex, Mellanox, and Chelsio)

Organizations that build large, complex environments will benefit from 
enhancements that provide a better system administration experience. 
These include:
   * The addition of Performance Co-Pilot (PCP), a framework and set of 
services supporting system-level performance monitoring and management 
in distributed environments
   * Improved manageability of resource lists in large, high 
availability configurations
   * Full support for load balancer technology like HAProxy and keepalived

Red Hat Enterprise Linux 6.6 also provides enhancements to running Red 
Hat Enterprise Linux as a virtual guest, upholding Red Hat’s commitment 
to refining the overall virtualization experience. Virtualization 
updates in Red Hat Enterprise Linux 6.6 include support for a host to 
feed randomness (entropy) 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 on a Red Hat Enterprise Linux 7 host, and more.
