Anounced Latest Version of Linux 6
Red Hat, the world's leading provider of open source solutions, on Tuesday announced the beta release of Red Hat Enterprise Linux 6.6, the latest version of its Red Hat Enterprise Linux 6 (RHEL) platform. RHEL 6.6 Beta is the latest iteration of the RHEL 6 platform which first introduced in November of 2010, it follows Red Hat's June release of RHEL 7.
From the kernel to the network stack, the new RHEL 6.6 Beta has been tuned to optimize performance, with support for much higher processor counts, memory limits, kernel optimization and a more efficient CPU utilization on large systems. The main areas of improvement and enhancement are in system performance, system administration, and overall virtualization experience. In addition, there's also support for container technology.
Increased System Performance
RHEL 6.6 provides a stable and secure foundation that enables enterprises to tailor their infrastructure to meet today's fast-evolving computing environment and business needs. RHEL 6.6 Beta delivers a variety of optimization and tuning improvements that provide increased system performance across physical, virtual, and cloud environments, those improvements include:
- Support for Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) to deliver low-latency high bandwidth network connectivity.
- A new socket polling implementation for reducing network latency and jitter.
- Support for high performance, low latency applications.
- A more efficient Kernel locking improvements to allow for increased CPU utilization on large systems.
- And last support for additional 40GbE network adapters.
Better System Administration
In addition, enterprises that build and manage large, complex IT projects can benefit from enhancements that provide a much better system administration experience. These enhancements include:
- Red Hat has updated packages for High Availability to match those in RHEL 7 platform, this include full support for HAproxy (a high-performance TCP/HTTP load balancer) and keepalived (an open source load balancer technologies).
- Improved manageability of resource lists in large, high availability configurations.
- A PCP or Performance Co-Pilot (a suite of tools and services for supporting system-level performance monitoring and management in distributed environments).
- A new SCAP (Security Content Automation Protocol) functionality for compliance testing.
Enhanced Virtualization Experience
There's a lot of interest in virtualization technology these days, RHEL 6.6 has better virtual guest functionality, upholding RHEL's strong commitment in enhancing the overall virtualization experience. The virtualization updates include support for an increased security for cryptographic applications, multi-queue performance improvements for guest network, storage throughput when running RHEL 6.6 Beta on a RHEL 7 host and many more.
Support for Container Technology
Red Hat is committed to helping its own customers adopt container technology in a safe and secure way, without compromising existing it infrastructure investments. The company's solution include support for containerized applications so that they can be safely deployed, certified, and supported across a wide range of choices – from virtual machines, private clouds to public clouds. Red Hat is bringing some features to RHEL 6.6, the new platform allows customers to containerize new and existing RHEL 6 applications, and deploy them to RHEL 7 without porting or making any changes to source code. This gives customers the flexibility to confidently run their containerized applications on RHEL 7 and RHEL Atomic Host (currently in High Touch Beta) platforms.
