Red Hat logo Red Hat has released version 2.1 of its Red Hat Enterprise MRG (Messaging, Realtime, and Grid) product. It extends and optimises the real-time (RT), messaging and cluster capabilities of Red Hat Enterprise Linux (RHEL); the software is used in environments such as the financial sector, where features for processing large numbers of transactions with reliable response times are important.

With this version, Red Hat has switched to a Linux kernel that is based on Linux 3.0-rt – a version of the kernel that has been optimised for real-time use by the RT tree developers. The kernel developers declared it suitable for production use in November and later announced that it would be promoted to long-term kernel status with support for at least two years.

The platform's "Grid Aviary API" now supports SSL, and the Grid Scheduler offers high availability (HA). Version 2.1 also adds event-based data sampling for measuring performance. Red Hat says that the messaging variant now supports IPv6 and works with Microsoft Visual Studio 2010 as well as the JBoss Enterprise SOA and Application Platform products. However, the messaging component of MRG 2.1 has not become available yet; it is due to be released "in the coming months".

A full list of changes and new features is available in the release notes. Red Hat Enterprise MRG 2.1 is optimised for RHEL 6.2 and above but can also be used with version 5.7.
