New Powerful SiC Semiconductors Take Efficiency, Performance and Reliability to New Levels
WARRENDALE, Penn. – Mitsubishi Electric, an industry leader in designing and manufacturing reliable, environmentally friendly uninterruptible power systems (UPS), today announces its latest three-phase UPS, known as the SUMMIT Series. This new UPS incorporates SiC (silicon carbide) semiconductors, the next generation of power modules, replacing the traditional Insulated Gate Bi Polar Transistors (IGBT).
Silicon carbide possesses many attractive traits as a power device, including higher switching frequencies and lower switching losses. In addition, silicon carbide inherently offers higher thermal conductivity, thereby promoting heat dissipation. These characteristics make silicon carbide the material of choice for semiconductors within the power industry.
Designed for data centers and other demanding mission-critical applications, the SUMMIT Series UPS is currently offered in 500 kVA with plans to introduce a 750 kVA model in the near future. Offering efficiencies greater than 98 percent at 50 percent load with a maximum efficiency 98.2 percent, the 500kVA UPS is a three-phase, on-line double-conversion system that supplies clean, continuous power to systems sensitive to fluctuations common in utility power. Higher efficiencies translate to lower energy usage and cooling costs, and also contribute to a lower total cost of ownership. Like other Mitsubishi Electric UPS products, the SUMMIT Series is lighter in weight than competitors’ products and has a minimal footprint, which allows data center owners to maximize floor space.
“The new SUMMIT Series truly is a game changer in our industry,” said Dean Datre, general manager, Mitsubishi Electric Power Products’ UPS Division. “The robust SiC semiconductor used to power the UPS modules takes performance and reliability to a previously unattainable level.
The SUMMIT Series UPS is available now and is fully supported by Mitsubishi Electric Power Products, Inc.’s factory–direct, 24x7x365 services, training, and application expertise, as well as a three-year parts and labor warranty.

The CloudBridge Connector feature of the Citrix NetScaler appliance connects enterprise datacenters to external clouds and hosting environments.
With it, you can configure a CloudBridge Connector tunnel between two different datacenters to extend your network without reconfiguring it, and leverage the capabilities of the two datacenters. Having a CloudBridge Connector tunnel configured between the two geographically separated datacenters enables you to implement redundancy and safeguard your setup from failure.
The CloudBridge Connector tunnel helps achieve optimal utilization of infrastructure and resources across two datacenters. The applications available across the two datacenters appear as local to the user.
To connect a datacenter to another datacenter, you set up a CloudBridge Connector tunnel between a NetScaler appliance that reside in one datacenter and another NetScaler appliance that reside in the other datacenter.
Rather than ignore or attempt to block the use of unsanctioned apps and devices in the workplace, organisations should seek to understand what it is that actually drives their users to shadow IT.
This is according to Julian Cook, director of UK business at M-Files, who warned today (September 3rd) that only by working together with employees can enterprises combat the security risks caused by the use of technology outside of IT’s control.
“Understanding the use of unauthorised devices and apps will allow stakeholders … to identify and agree sanctioned solutions,” he said, arguing that this will support “both security and data protection across the business”.
(MCT) - Fort Lauderdale, Fla. City commissioners fear the regional 911 dispatch system the city joined a year ago isn't doing the job it was supposed to, and is putting visitors and residents at risk.
They're asking City Manager Lee Feldman to come up with a Plan B — including the potentially expensive option of leaving the system — if the county can't quickly fix the emergency dispatch system's continuing problems.
Feldman sent a letter last week to County Administrator Bertha Henry critical of the "underperforming" system and requesting a meeting with the participating cities to discuss performance issues and how they will be resolved.
Given the pervasiveness of SaaS applications like Office 365 and Salesforce, you’d think we’d have a pretty good handle on SaaS data protection by now. But according to Jeff Erramouspe, we’d all probably be surprised by how many IT departments, users and executives have failed to fully understand the nuances of proper SaaS data backup and recovery.
Erramouspe is vice president and general manager of EMC’s Spanning unit, which provides data backup and recovery for cloud applications. In a recent email interview, Erramouspe shared some misconceptions about SaaS data protection, beginning with the notion that SaaS application data doesn’t need to be backed up:
While it is true that SaaS vendors do protect and replicate their customers’ data, they only do it to protect the customer from problems on the SaaS application infrastructure side, such as server failures or drive crashes. They don’t necessarily provide bullet-proof protection from user-driven data loss. You’d be surprised by how many experienced IT professionals don’t know this. While the cloud is a great place to cost-effectively run applications, accidental deletion and other mistakes can cause losses from which Google, Microsoft, and Salesforce.com can’t always help you easily recover. For Google, its policy states that if you permanently delete something, it’s not recoverable—it’s gone forever. Salesforce has a paid service to get data back, but it is expensive ($10,000 per incident), takes time (as much as up to three weeks to get started) and it only commits to best efforts—most data can’t be restored in full. And the Microsoft Office 365 SLA doesn’t include data recovery, despite the belief of many customers that it does.
Three in four small business owners in the US do not have a disaster recovery plan, but more than half say it would take at least three months to recover from a disaster. For companies with fewer than 50 employees, only one in five (18%) have a disaster recovery plan. That is according to a new survey of US small business owners conducted by Harris Interactive on behalf of Nationwide Direct and Member Solutions.
“Small businesses are least likely to have disaster recovery insurance,” says Mark Pizzi, president and chief operating officer of Nationwide Direct and Member Solutions. “And yet they are the ones most affected by a disaster. That’s why it’s essential for small businesses to have a disaster recovery plan.”
For many without a plan for their business, disaster recovery is simply a low priority (34%). Time (11%) or cost (15%) both play less of a role in the decision not to have a written disaster recovery plan in place. Nationwide Direct note that America's small business owners may be feeling overconfident as one in four (26%) believe the likelihood of a natural disaster occurring in their area is slim and just over one-third (37%) say climate change and the weather phenomenon El Nino have decreased the likelihood of a natural disaster impacting their business.
Perhaps that overconfidence is also reflected in the Business Continuity Institute's latest Horizon Scan report which showed that business continuity professionals working for SMEs globally were less concerned about the prospect of a natural disaster than larger organizations. For example, with adverse weather only 41% expressed concern about this threat materialising, whereas this figure was 55% for larger organizations.
Assumptions can be the downfall of even the best Business Continuity Plan (we’ve addressed that issue in an early blog). Sometimes it’s not the overt assumptions we make (“All critical IT systems will be available within 4 hours of the disruption.”) but the ones we don’t realize we’ve made that may jeopardize our ability to recover – or sustain a recovery.
Chief among these, of course, is the unspoken assumption that our Plan will work, everything will be restored in short order and our business will be back to ‘normal’ within hours – or at worst in a day or two. It’s a common assumption. Even if it’s not written into the Plan, that short recovery horizon may be implied -simply because we don’t plan for what we may need if the recovery takes longer (a week or a month or more). It is curious that many organizations don’t plan for prolonged disruptions – especially when the majority of Business Impact Analyses (BIA’s) ask about impacts over extended time periods. Why ask a process owner what resources they’ll need 4 weeks after the disruption – then only require them to plan for a 48-hour recovery?
Most IT organizations spend a fair amount of time trying to figure out the actual cost differential between delivering IT services via a public cloud versus on premise. There’s no doubt that virtual machines running in a public cloud are going to be less expensive, but when all the costs of delivering an IT service are fully loaded, the public cloud is not always the cheaper choice.
To help IT organizations sort through that financial morass, Cloud Cruiser this week announced it has added CloudSmart-Now templates to its cloud financial management service. The templates make it simpler for IT organizations to figure out their true costs across hybrid cloud computing environments.
Deirdre Mahon, chief marketing officer for Cloud Cruiser, says the templates were built around a service that collects cost data from Amazon Web Services (AWS), Azure, Windows Azure Pack (WAP), VMware and Openstack. The entire IT financial analytic service can be set up in as little as five days and continually monitors pricing changes being made by the “Big Five” cloud service providers. Using that data, IT organizations can then make a more intelligent choice about where to host any given application workload.
The degree of interdependence across critical infrastructure sectors has been amplified by globalization, advanced technologies and supply chain pressures. Our team at Johns Hopkins University Applied Physics Laboratory is studying — through modeling, analyses and empirical research in places such as the Port of Baltimore and Austin, Texas — the measurable impact of disruptive events, governance and societal demands upon resilience ecosystems in bounded geographic areas.
Governments, communities and individuals are not helpless in the face of natural disasters like Typhoon Haiyan, the category-5 super typhoon that struck the Philippines in November 2013, killing thousands and displacing hundreds of thousands. There are practical safeguards that can be designed within the multidisciplinary worlds of engineering, cyberphysical, and the social, behavioral and economic sciences if we systematically identify the independent variables that contribute to critical infrastructure interdependencies, conduct analyses that support a generalizable model, and test these methods under simulated and real-world conditions. Drawing from the principles of collective action theory and computational analytics, our studies are seeking to quantify the cost accounting and value proposition behind resilience by integrating economic factors into the research.
