		<description><![CDATA[Linux continues to innovate in the area of file systems. It supports the
            largest variety of file systems of any operating system.  It also provides
            cutting-edge file system technology. Two new file systems that are
            making their way into Linux include the NiLFS(2) log-structured file system
            and the exofs object-based storage system. Discover the purpose behind these
            two new file systems and the advantages that they bring.]]></description>

		<description><![CDATA[Not only has virtualization advanced the state of the art in maximizing
            server efficiency, it has also opened the door to new technologies that were not possible before. One of these technologies is the virtual appliance, which
            fundamentally changes the way software is delivered, configured, and managed.
            But the power behind virtual appliances lies in the ability to freely share
            them among different hypervisors. Learn the ideas and benefits behind virtual
            appliances, and discover a standard solution for virtual appliance
            interoperability called the Open Virtualization Format.]]></description>

		<description><![CDATA[Booting servers from storage area networks with multiple paths can
            provide significant benefits for the complex, modern data center environment
            -- benefits such as improving availability and increasing your reach when it
            comes to easier management and maintainance and in providing reliability. To
            boot your Linux system from a SAN device, you&apos;ll need to set up a SAN boot
            operating system to your storage with multipath driver support; that&apos;s where

		<title><![CDATA[Linux on POWER: Distribution migration and binary compatibility
            considerations]]></title> 
		<description><![CDATA[Learn about binary compatibility as it relates to the different
            operating environments that run on Linux on POWER. Examine the two Linux on
            POWER distributions supported by IBM, Red Hat Enterprise Linux (RHEL) and SUSE
            LINUX Enterprise Server (SLES), with regard to the binary compatibility
            between their respective releases. In general, a smooth transition from the
            2.6.9 kernel-based RHEL4 to the 2.6.18 kernel-based RHEL5 is <!--observed
                due to--> made possible by 
            the stable Application Binary Interface (ABI) maintained between the releases.
            The same can be said when moving from the 2.6.5 kernel-based SLES9 to the
            2.6.16 kernel-based SLES10. Learn about new technologies that can provide
            performance enhancements for a Linux on POWER application, and follow steps to
            ensure binary compatibility across multiple distributions in the future.

		<description><![CDATA[Cloud computing and storage convert physical resources (like processors and
	storage) into scalable and shareable resources over the Internet (computing and storage
	&quot;as a service&quot;). Although not a new concept, virtualization makes this much more scalable
	and efficient through the sharing of physical systems through server virtualization. Cloud
	computing gives users access to massive computing and storage resources without their
	having to know where those resources are or how they&apos;re configured. As you might expect,
	Linux plays a huge role. Discover cloud computing, and learn why there&apos;s a penguin behind
	that silver lining. [And see the new Resource links to the latest developerWorks content on cloud computing. -Ed]]]></description>

		<description><![CDATA[To efficiently achieve uniform mounting in the presence of multiple,

            those versions. The article

		<title><![CDATA[Lazy Linux: 11 secrets for lazy cluster admins]]></title> 
		<description><![CDATA[&quot;Cluster&quot; means different things to different people. In the context of
            this article, cluster is best defined as &quot;scale-out&quot; -- scale-out clusters
            generally have a lot of the same type of components like
            Web farms, render farms, and high performance computing (HPC) systems.
            Administrators will tell you that with scale-out clusters any change, no
            matter how small, must be repeated up to hundreds of thousands of times; the
            laziest of admins have mastered techniques of scale-out management so that
            regardless of the number of nodes, the effort is the same. In this article,
            the authors peer into the minds of the laziest Linux admins on Earth and
            divulge their secrets.]]></description>

		<title><![CDATA[TASK_KILLABLE: New process state in Linux]]></title> 
		<description><![CDATA[Linux kernel 2.6.25 introduced a new process state for putting processes
            to sleep called TASK_KILLABLE, which offers an alternative to the efficient
            but potentially unkillable TASK_UNINTERRUPTIBLE and the easy-to-awaken but
            safer TASK_INTERRUPTIBLE. TASK_KILLABLE is the outcome of an issue raised in
            2002 about the OpenAFS file system driver waiting for an event interruptibly
            after blocking all signals. This new sleeping state echoes
            TASK_UNINTERRUPTIBLE with the ability to respond to fatal signals. In this
            article, the author sheds light on this area and, using examples from 2.6.26
            and an earlier version, 2.6.18, discusses the related changes to the Linux
            kernel and the new APIs that resulted from these changes.]]></description>

            read, write, and create. Inotify is reactive, surprisingly simple to use, and
            far more efficient than, say, busy polling from a cron job. Learn how to
            integrate inotify into your own applications, and discover a set of

		<description><![CDATA[Dynamically linked shared libraries are an important aspect of
            GNU/Linux. They allow executables to dynamically access external functionality
            at run time and thereby reduce their overall memory footprint (by bringing
            functionality in when it&apos;s needed). This article investigates the process of
            creating and using dynamic libraries, provides details on the various tools
            for exploring them, and explores how these libraries work under the hood.]]></description>

		<title><![CDATA[Work the CIM event model efficiently]]></title> 
		<description><![CDATA[In the Common Information Model (CIM), a client application can
            subscribe to be notified of CIM events. Normally, an application can create
            event filters with multiple event handlers through different connection ports,
            but this consumes lots of network resources and adds much complexity when it
            comes to maintenance. In this article, see how to register
            multiple CIM event handlers with a single specific connection port.  Also
            pick up some tips on how to write code with the SBLIM CIM client library.]]></description>
