How the Rack is Changing the Cooling Game
One of the newest forms of liquid cooling is the rear-door heat exchanger (RDHx). The RDHx can be added to existing equipment racks, or you can provide new rack enclosures with an RDHx incorporated as part of the new rack enclosure. RDHx systems can provide supplemental cooling support for a few high-density racks, or provide the total cooling solution with or without a raised floor.

How Big Data Becomes Smart Data
Some would say that only human intelligence can transform data into insight. While it certainly takes intelligence to interpret data, such a statement begs the question as to how to make the connections necessary to reach actionable conclusions from these massive repositories of information. In other words, how do we turn Big Data into Smart Data? Context, it turns out, is key. When we examine the surrounding environment and identify the types of data that influence a given situation, we can cross-analyze those sets to provide illumination.

Is the Internet of Things More Fact or Fiction?
Though Cisco and several other vendors have thrown tremendous support behind the IOT, most channel organizations continue to maintain a wait-and-see attitude until the business case is more firmly established. Of course, many of the core technologies required to drive this Internet-enablement initiative are already here, including wireless networks, RFID and barcode readers, temperature sensors and other measurement systems.

Has Hadoop Entered the Mainstream?
After all the hype around Apache Hadoop, we are starting to see some successful implementations that highlight its benefits. However, we do not yet see the kind of enterprise adoption typically associated with a technology that promises to manage high volumes, reduce implementation costs and, more importantly, monetize data. The question is why?

Shattered Trust: IT Survey Shows PRISM Allegations Have Brought Cloud Misgivings
A survey of Redmond magazine's readership also shows a significant number of organizations are putting some planned cloud migrations on hold, while many are retreating from those already underway. More than one-third put planned projects on hold in wake of the NSA leaks, while 13 percent brought cloud projects back in-house, according to an online survey of 300Redmond readers conducted in mid-August.

Rethinking high-availability architecture: Scale out to save money
A more economical approach is a scale-out multiserver architecture, where the workload is shared across multiple servers. A classic example is a Web server farm. To improve website performance, you use more VMs and only care about having enough Web servers running to support the current load. Newer open source database servers have the same sort of architecture: Redis, Apache Cassandra and MongoDB all scale out for performance rather than requiring a single-node scale-up.

The real value of introspection
The notion that we just lead outwardly and spend no time inwardly belies the value of introspection. Introspection and its byproduct, self-awareness, are central to any leadership, no matter what level or position. It is the essence of decision-making, behavioral efforts, action, focused energy, prioritization. Introspection is the key to clarifying what you stand for and what matters to you — in other words, what is important. It drives who we are in all aspects of our leadership.

Why a secure, multi-vendor strategy is crucial for the cloud
Even before you went to the cloud, you (hopefully) had a backup strategy in place that would help you recover critical systems in the event of an equipment malfunction or disaster. Perhaps your first foray into the cloud was as a backup measure, replacing tape or other backup media with highly scalable cloud storage. But if you are running primary or mission critical applications in the cloud, it’s even more critical that you have a plan should your provider go down for a few minutes—or forever.

Experts, users weigh in on OpenPower's open source data center systems
With denser chip-level transistors and more on-chip integration, processors can share a chip with GPUs, peripheral bus controllers (PCIe or even USB) and network interconnects. These system-on-a-chip designs are simpler and less expensive for server makers because there are fewer chips to connect and test externally on a motherboard. However, there is a disconnect between what server vendors are developing and what data center teams want, said Doug Feltman, director of systems and applications at 24 Seven Inc.

Software Is Eating Your Organizational Silos
There’s no question that ultimately, we’ll find all of our applications running in service-level, on-demand infrastructure. The software running on commoditized hardware will itself be commoditized. The vast majority of our applications will no longer be unique snowflakes with highly specific infrastructure requirements — instead, they’ll be able to run on common software platforms that eliminate the need at the application layer to worry about infrastructure at all
