Storix has brought forth a new version (6.0) of its flagship backup and disaster recovery application, System Backup Administrator (SBAdmin). SBAdmin not only backs up data files to a network server, but it also provides the ability to rebuild a system from the ground up on different hardware environments. One can reconfigure the system to restore onto completely different hardware, change filesystem types, migrate from disk partitions to LVM or software RAID and so on. Examples of new features are a Web-based interface, Oracle DB backup, remote system installation and balancing of the CPU load against the backup size. Supported OSes include Linux and AIX; supported hardware includes all Intel-based (x86/Pentium), IBM pSeries (32/64-bit) and HP Integrity (Itanium 2).
Vyatta's Open Flexible Router (OFR), upgraded recently to version 1.1, is an open-source LAN and WAN routing solution for small- to medium-sized businesses. OFR's product benefits include not only all standard routing protocols and high-availability and security features, but also the ability to customize the product and add features as needed. The latter feature gives users flexibility in managing future requirements on their own terms rather than relying on the actions of closed-source vendors. Vyatta also states that OFR allows one to deploy an “enterprise-class router for a fraction of the cost of a traditional closed-source, proprietary router”. This latest release adds support for T3 WAN connections and provides compatibility with third-party application packages from Debian GNU/Linux. Debian package compatibility extends OFR's capabilities to include third-party applications in the Debian universe, such as Openswan, Asterisk and ClamAV, among others. The OFR software is available for download from Vyatta's Web site.
XenSource has gone hog wild with its concurrent announcement of three different virtualization products: XenEnterpriseT, XenServerT and XenExpressT. The products target the needs of “Fortune 50 enterprises, mid-market Windows standard server IT environments to technology enthusiasts and developers”, respectively. All three products share a common, open-source, Xen-based architecture, which makes “the upgrade path seamless between products”, sayeth XenSource. Xen allows multiple virtual server instances to run concurrently on the same physical server, with near native performance. XenEnterpriseT is designed for the heterogeneous environment of enterprises, delivering “bare metal” performance for virtualized guest operating systems. Meanwhile, XenServerT is intended for Windows standard server environments and “gives IT professionals a high-performance, easy-to-use virtualization platform for Windows”. Finally, XenExpressT is made for for developers and technology enthusiasts, offering a “comprehensive, production-ready, free product, which enables anyone to get started with Xen virtualization quickly”. All three products support Windows Server 2003/2000, as well as Windows XP, Red Hat Enterprise Linux, SUSE Linux Enterprise Server and Debian Sarge guests.

Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
