The Red Hat Enterprise MRG platform includes a new Linux kernel, expanded RHEL support and improved performance.
Red Hat updated and expanded its Red Hat Enterprise
Messaging, Realtime and Grid Linux platform, a critical set of tools for building
and managing a private cloud, the company said on Oct. 14.
The enhancements in Red Hat Enterprise MRG 1.3 include
adding support for Red Hat Enterprise Linux 4.8 and 5.5, improving Messaging
APIs, optimizing performance and scalability, and expanding new management
Red Hat Enterprise MRG is a collection of three different
advanced messaging, real-time computing and grid computing - for Red
Hat Enterprise Linux 5. The distributed computing platform features high-speed
interoperable and open standards messaging tools, a deterministic low-latency
real-time kernel based on Linux 2.6.33 kernel and high-performance and
throughput computing grid scheduler for distributed workloads and cloud
The Grid functionality had the most extensive updates in
this release. A key enhancement allows IT managers to build out complex infrastructures
that consist of multiple cloud environments, both public and private.
Along with integrated support for virtualization and public
clouds, the Grid module can also aggregate multiple cloud resources into one
common computing pool. These changes provide IT managers with flexible
computing across private, public, and hybrid clouds and streamlined operations
across remote grids with servers, Red Hat said.
The release includes new user tools, Windows Execute Node
support, enhanced workflow management, resource restriction capabilities,
update configuration management and new administration tool. With these
updates, customers will gain the ability to scale to tens of thousands of
devices, be able to provision virtual machines, centralize configuration and
management and utilize cloud spill-over capabilities.
Based on the University of Wisconsin, Madison-hosted Condor
Project, the Grid module introduces flexible deployment to various applications
and workloads. With the Red Hat Grid component, IT managers can scale out
applications with real-time or high-performance needs or take advantage of
better asset utilization for applications.
In Enterprise 1.3, the Messaging component features updated
clients with improve performance, and enhancements that optimize performance
and increase stability in clustered environments. New protocol version
independent C++ and Python clients, Windows C++ client and additional QMF APIs
are also available.
The new MRG Messaging can now be used on JBoss Enterprise
SOA Platform and has a number of security improvements, such as Kerberos
support. The messaging component is built on the Advanced Messaging Queuing
Protocol, which can handle multiple kinds of messaging functions at the same
Enterprise MRG's updated Realtime kernel includes the new
Performance Counter subsystem and the associated perf performance tool to
enable greater performance capabilities. As real-time still has trade-offs in
performance levels, low-latency is the preferred option over real-time to
ensure mission-critical systems remain up and running. With the Realtime
kernel, IT managers can make the necessary adjustments for each application.
Red Hat will be introducing a new MRG Realtime hardware
self-certification program soon, the company said in its statement. The new
hardware enablement and certifications in the module are designed to work with
the program, according to Red Hat.
Rival Novell has a similar real-time product, called SUSE
Linux Enterprise Real Time.
Red Hat Enterprise MRG, first released in 2008, is part of
Red Hat Cloud Foundations suite. Red Hat uses the same set of compilers for
both Red Hat Enterprise Linux and Enterprise MRG so applications certified for
RHEL will be supported without the need to recertify on Enterprise MRG. The
platform is available only for x86 and x64 hardware at this time.
Customers with an Enterprise MRG subscription will
automatically receive the 1.3 update via the Red Hat Network. Under Enterprise
MRG 1.3, Grid is fully supported for everyone, even customers without a
technical account manager, Red Hat said.
