K Data Grid

All Windows on Linux and Unix Server Founder New here:)

Red Hat Enterprise MRG was first published in June 2008, her debut Red Hat's messaging, real-time offers Grid technology. In February 2009, the company offers improved performance, clustering, security and improvement of tools, with full support for the product functionality of the grid. Today, Red Hat releases Red Hat Enterprise MRG 1.2 which includes key performance enhancements and support for Red Hat Enterprise Linux 5.4.

   • Mail on KVM performance virtualized more than one million messages per second throughput
   • Mail KVM performance on virtualized latency under 200 microseconds, reliable recognition
2. Realtime
   Red Hat Enterprise MRG Improvements real-time performance improved 1.2 deterministic low latency performance-intensive workloads and time critical. In addition, MRG Realtime includes a new tool, rteval to help customers detect latencies of hardware in their systems. With Red Hat Certification Program equipment for intensive firms MRG Realtime, rteval provides its customers with the tools and the assurance that all infrastructure, equipment for the system operations, provides optimal performance for workloads in real time.
3. Grid
   With Enterprise MRG feature Grid, customers can plan their Web server and other applications to run in distributed environments and cloud computing, and can acquire appropriate resources to accomplish these tasks. With the update 1.2, Enterprise MRG Grid can now support the programming of the KVM-based virtual machines Red Hat Enterprise Linux 5.4, and provides greater scalability for large deployments of clouds.

   Technology Enterprise MRG Grid is based on Open Source Condor project, which was developed by the University of Wisconsin-Madison. Condor 7.4, released in early November, is incorporated into the Enterprise MRG 1.2, enabling customers to use part of the last High Throughput Computing technologies available today, in a fully supported product.

Customers with a subscription Enterprise MRG automatically receive Update 1.2 Today via Red Hat Network.
