Even the datacenter is mobile driven

By David Chernicoff | May 13, 2011, 8:51am PDTWhen Unisys announced new additions to its Clearpath Enterprise Server line, the Dorado and Libra 800, the lead information provided about the new servers wasn't so much focused on the mission critical role that these servers are designed to play as it was on the fact that they can be accessed via mobile devices.Unisys makes some very interesting enterprise-class server products that reflect well on its heritage as a mainframe computer provider.  They are in the process of moving their server lines from their own CMOS processors to industry-standard Intel Xeon CPUs and continue to enhance their software components, from their Clearpath MCP software to their high-end fault tolerant XPC-L clustering technology.But even Unisys realizes that to get attention from potential new customers they need to cater to the high-profile mobile market regardless of the small number of users likely to take full advantage of such solutions. It's not …

Cooling management appliance a perfect fit for legacy datacenters

By David Chernicoff | May 12, 2011, 6:47am PDTWith so many changes going on in the way that datacenters are built and equipped, the huge amount of new construction being done, and the wealth of new technology focused on building state-of-the-art facilities, it is sometimes easy to lose sight of the fact that the majority of datacenters in use aren't in a position to take advantage of all of the advances in facilities design and management.We forget that the standard datacenter in use today can still bring back memories of the design introduced for mainframes in the 1960's; a large room with a raised floor, filled with racks of computing equipment and kept  chilled by massive CRAC (computer room air conditioning) units that run constantly to maintain the required operating temperature in the facility. And while new datacenters are built from the ground up with energy efficiency as a stated design goal, the vast majority of datacenters in use were designed during a time of more …

Maximum energy efficiency may require single source datacenter

By David Chernicoff | May 11, 2011, 9:50am PDTOne of the keys to building an energy efficient datacenter is to minimize energy wasting operations.  This might seem obvious, but the ramifications of the process might not be. Beyond looking at power delivery, cooling solutions, and IT hardware that operates as efficiently as possible, there is the issue of managing all of these disparate elements and a single entity. The goal of delivering power, cooling, and computing power only when and where needed in many ways defines the focus for datacenter management in the future.With this in mind, vendors of datacenter equipment, everything from power delivery units, to chillers, to the actual computing hardware, are instrumenting everything possible.  They know that their customers want to be able to monitor and control the workload across their datacenter, and providing that hook, and support for APIs that link into major management platforms will allow potential customers to integrate these …

10 pitfalls of rookie management teams

By Steve Tobak | May 10, 2011, 8:33 AM PDTI've worked with and consulted for hundreds of startups, entrepreneurs, and relatively inexperienced management teams. I also was an inexperienced executive myself, once upon a time. Lots of water under the bridge, I can tell you that.Now, I wouldn't begrudge anyone the unique growth experience of learning from his own mistakes, especially the wisdom and humility that only failure can impart on the executive ego.That said, savvy managers listen to the voice of experience. They may choose to ignore the advice, but they still listen. Information is power, forewarned is forearmed, and all that.When asked in a CNBC interview what keeps her up at night, Christine Day, CEO of fast-growing, high-flying athletic apparel maker Lululemon Athletica, said, "Scaling the growth. Our growth has been phenomenal, and that puts a lot of pressure on a young management team."Day, who spent 20 years at Starbucks, most recently as president of the…

10 reasons why you should give Slackware Linux a chance

By Jack Wallen | May 11, 2011, 11:37 AM PDTSlackware. You've either used it, thought about using it, or you're scared of using it. Slackware Linux is one of the most powerful distributions available. But that power comes with a price — it's not nearly as user-friendly as many other distributions. In fact, Slackware is typically bested only by Gentoo for level of difficulty.But if you avoid Slackware, you miss out on quite a lot. I can think of at least 10 reasons why you should give Slackware a try (or another chance). Before you hold up your hands in the middle of the installation and cry out, "I give up!" give these reasons a read.Note: This article is also available as a PDF download.1: StabilityIf you're looking for the best of the best, you will be hard-pressed to find a Linux distribution that enjoys more stability than Slackware — and that's saying quite a lot! Slackware has been around for 20 years now, and for the longest time it has enjoyed the …

Five power-saving tips for maxed-out datacenters

By Rick Vanover | May 6, 2011, 2:58 PM PDTWe all deal with some form of datacenter or office that is at the brink of power capacity. I can't tell you how many times I bump into situations where a computer room can't accommodate another server or storage device — let alone deliver enough cooling capacity — due to lack of available power in the facility,. Over the years, I have discovered a few tricks to save power.Note: These tips are based on an entry in our Network Administrator blog.1: VirtualizeThere is no single more effective power reduction strategy for the datacenter than server virtualization. While the hosts (VMware ESXi or Microsoft Hyper-V) may be larger and consume more power per server unit than traditional physical servers, high consolidation ratios can lower the average power consumption per server.2: Consider group policy objects for PCsIn modern versions of Active Directory, Group Policy configuration can set the power plan by policy. This is located in Comput…
