Red Hat Enterprise MRG 1.1 released
Eight months after version 1.0 was originally released, Red Hat has released Red Hat Enterprise MRG 1.1, it's Linux platform for time-critical applications. The Grid capabilities in the 1.0 release were still experimental, however Red Hat says that they are now fit for use in production environments. MRG stands for Messaging, Realtime, and Grid. A white-paper about the components describes them in further detail.
Red Hat Enterprise MRG 1.1 promises better performance in three areas. Native OFED Infiniband Support and RDMA (Remote Direct Memory Access) help to provide for better Messaging latency ratios and Active-Active clustering is also new in the release. The tools in the Messaging and Grid components of MRG have been revised and updated and the Grid component now includes support for cloud-based environments, such as EC2 from Amazon.
While Red Hat Enterprise MRG is optimised for Red Hat Enterprise Linux (RHEL), the system can also run under Windows or Solaris, however components like Grid scheduler, or the real-time abilities, are only available when running a Linux kernel.
