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.
