Is btrfs is better than ZFS?
Rudd-O.com Disputes the Notion

A post on Rudd-O.com challenges the view that btrfs is superior to ZFS, noting that the advantages of ZFS are practical consequences of the user-centered design decisions that obtained during the its development. Among the distinctions giving the edge to ZFS are that ZFS organizes file systems as a flexible tree while btrfs does not enable organizing subvolumes; ZFS file system operations can apply recursively but not in btrfs; ZFS auto-mounts file systems by default; ZFS tracks used space per file system; ZFS distinguishes snapshots from file systems, and so forth, with the evidence falling preponderantly on the side of ZFS.

Q&A About the Latest Oracle Linux Releases
Monica Kumar, Senior Director, Oracle Linux, Shares the News
Monica Kumar, Senior Director, Oracle Linux, Oracle Virtualization, and MySQL Product Marketing, joins Zeynep Koch in a post on Oracle's Linux Blog for a Q&A on Oracle's latest Linux releases: Oracle Linux 5.9 and 6.4. Oracle Linux customers enjoy several advantages over users of RHEL and SUSE, she says, which include the latest technology, the latest word in best testing and deployment practices; 24/7 world-class support at the lowest cost; and free access to software (both binaries and patches). Kumar concludes with the announcement that 2013 will see further releases of both Oracle Linux 5 and 6, as well as the Unbreakable Enterprise Kernel.

China Mobile Fujian Implements Oracle Exadata Database Machine
Improves System Performance 2X, Data Compression 3X-5X
Using Oracle Exadata Database Machine has enabled China Mobile Fujian to replace its legacy infrastructure and develop an enterprise-level data warehouse for its next-generation BASS. Switching to Oracle Exadata improved system performance by 4X and data compression by the range of 3X-5X. Prior to the deployment of Oracle Exadata Database Machine, China Mobile Fujian could store only 70 Terabytes (TB) of data in its data warehouse, greatly restricting the business analysis. Now, the company can store and process 250 TB of data, including historical data about its mobile customers and the services used; the data mart access layer; and operational, financial, and analysis reports.

Optimizing Storage Systems for DB Workloads
While Guaranteeing Best in Class Performance and Ease of Integration
Storage devices must embed a variety of features so that the optimal level of performance, manageability and operational agility can be achieved. Oracle's Exadata Engineered System does exactly that by embedding dedicated and highly optimized storage nodes that take in charge a part of the database workload in a way that a separate standalone storage device cannot. Philippe Deverchère reviews the requirements that must be met before one can deliver storage systems that can be used as primary storage for databases while guaranteeing best in class performance and ease of integration, noting that Sun ZFS Storage Appliance meets these requirements in large measure.

    TDF White Paper Aids Migrations to LibreOffice
    Outlines Comprehensive Change Management Process
    The Document Foundation (TDF) has released the "LibreOffice Migration White Paper," a guide for enterprises wishing to adopt LibreOffice and other free software. The guide is framed in terms of dealing with both the technical aspects of such a migration and the resistance often encountered in the work force when long-term working habits are challenged. Developed in Open Document Format (ODF), LibreOffice is the standard document format recognized by the largest number of organizations and supported by the largest number of desktop software solutions. Legacy investments are thereby protected even as enterprises undertake migration to ODF.

    What Is the Future for Sysadmins?
    Some Points to Ponder from Rick Ramsey
    In a post that encourages readers to become Solaris Sysadmins Rick Ramsey refers to three videos:

    • Why Is Oracle Investing So Heavily in Solaris?
    • Why Is The OS Still Relevant??
    • An Engineer's Perspective on Why the OS Is Still Relevant

    If Oracle's engineered systems not only reduce the complexity of managing the data center, but need fewer sysadmins to run them, why become a Solaris Sysadmin, Ramsey asks and answers that question referring to two more videos, one an interview with Larry Wake (Why Become a Solaris Sysadmin?) and the other an interview with Marshall Choy (Impact of Engineered Systems on the Sysadmin).

Training sessions are also offered on Oracle Fabric Interconnect Administration and on Oracle VM Server for SPARC: Installation and Configuration.
    Managing Tape Storage: Is It Really as Difficult as has been Thought?
    Not with Oracle's StorageTek Tape Analytics
    Oracle's StorageTek Tape Analytics (STA)answers many concerns about tape storage. "This system," Brian Zents posts, "does the analysis for you, leaving you with proactive recommendations and resulting corrective actions … just like disk." He further explains that STA is an intelligent monitoring application for Oracle tape libraries that allows users to make informed decisions about future tape storage investments based on current realities. He adds that it is also is used to monitor the health of your tape library environment. Its functionality can be utilized regardless of the drive and media types within the library, or whether the libraries are in an open system or mainframe environment.

    An Overview and a How-to on Protecting Your Oracle Solaris Zone Cluster
    Labeling Zones for Appropriate Access

    Rick Ramsey posts an introduction to zones, clustering, and trusted extensions and a link to a paper by Subama Ganguly on building a secure zone cluster with trusted extensions. As Ramsey writes in his introduction, "Oracle Solaris Trusted Zone clusters became available in Oracle Solaris Cluster 4.1. They are zone clusters with the security capabilities (mandatory access control or MAC) provided by Trusted Extensions. The zones in the cluster are labeled in the same way that other objects are labeled, so that only other objects with the same (or higher) sensitivity label can access them. Subama Ganguly walks you through setting one up.
