Splunk says that version 4 of its IT search application has hit the streets, offering improvements in usability, scalability and performance. Splunk 4 enables users to search, analyze, monitor and report on data from any application, server or network device in real time to troubleshoot outages, investigate security incidents, meet compliance requirements and more—“in minutes instead of hours or days”, says the company. Some of the 1,800 enhancements and 50+ new features include 10x faster search and 2x faster indexing, custom dashboards for users of any skill level, more sophisticated enterprise-level management and the Splunk 4 App Framework for creating or leveraging existing apps running on the IT search engine.
The “ounce of prevention” guys at H.D.S. Hungary have released version 2.9 of Hard Disk Sentinel, a data protection solution that monitors the status of solid-state and hard disks. Hard Disk Sentinel provides detailed disk information, statistics, alerts and backup functions, alerting to present or future disk problems, such as excessive temperature or degradation of disk health, which are signs of imminent hardware failure. The company touts the solution's unique support for a wide range of both internal IDE/SATA/SCSI/SAS and external USB/FireWire/e-Sata hard disks and hard disk enclosures. The new version 2.9 offers deep disk tests to verify hard disk noise, performance and temperature changes. In addition, disk information in RAID arrays connected to 3ware/AMCC and ARECA RAID controllers and solid-state disk features also can be detected. The Enterprise server solution allows monitoring and managing of disk information of remote hosts from a centralized administration console.
Making the space for on-line video more interesting is Kaltura Community Edition (KCE), which Kaltura dubs “the world's first and only open-source, self-hosted on-line video platform”. The freely downloadable KCE allows any site owner or Web developer to integrate customizable video and interactive rich-media functionalities, including video management, publishing, uploading, importing, syndicating, editing, annotating, remixing, sharing and advertising. Kaltura also claims that KCE breaks the “build vs. buy” conundrum and vendor lock-in by allowing publishers and enterprises to build upon and extend an existing robust platform to customize fully their own self-hosted solution on their own servers, behind their own firewalls and at no cost. The company further offers paid support services. KCE runs on Linux, Mac and Windows and is slated to be available on several cloud computing platforms.
If you are an administrator who has worked with *nix but is new to virtualization, the authorial team of Luke S. Crawford and Chris Takemura has a book for you: The Book of Xen from No Starch Press. Xen is a tool that lets administrators run many virtual operating systems on one physical server, including Linux, BSD, OpenSolaris and Microsoft Windows. In the process, users save money on hardware, maintenance and electricity. The book explains everything needed to run Xen, covering installation, networking, virtualized storage, and managing guest and host operating systems. Beyond the basics, it covers profiling and benchmarks, migration, XenSource administration and hardware-assisted virtualization.
Although the engineering discipline has done many wonderful things for civilization, it has at times been blind to important social and environmental considerations. In order to foster more humane disciplines of engineering, the team of David Douglas and Greg Papadopoulos penned the new book Citizen Engineer: A Handbook for Socially Responsible Engineering (Prentice-Hall). Citizen Engineer helps engineers of all types to see the full impact of their work beyond design to include ecological, intellectual property, business and sociological perspectives.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
