Apple is using solar arrays, including a 100-acre solar energy farm in Maiden, N.C., to help power a data center there. Apple allowed NBC's Today show inside the facility this week, and during the tour, a reporter asked what the temperature was there. "It's about 103 degrees in here," said Lisa Jackson, Apple's vice president of environmental initiatives and a former Obama administration EPA chief. What wasn't explained is that Jackson and the reporter were walking down a hot aisle, and feeling the fan exhaust. The experience might have been different if they had walked down the cold aisle, where the rack fronts face the aisle. Apple isn't disclosing details about its Maiden data center operations, except at the 30,000 foot level, so it's unknown exactly what temperatures it's operating at. But it is possible to estimate a range. The American Society of Heating, Refrigerating & Air-Conditioning Engineers (ASHRAE) sets temperatures and humidity guidelines for data centers based on what it knows about the equipment inside them. It recommends that data centers operate between 64.4 to 80.6 degrees Fahrenheit. The recommended limit concerns the air intake temperature. The exhaust temperatures will be higher, how much higher will depend on the density and the quality of the air management, according to the Uptime Institute vice president Keith Klesner. But the temperature could be approximately 15 to 30 degrees Fahrenheit higher, he said in an email. Dave Kelley, director of application engineering at Emerson Network Power's Liebert Precision Cooling, narrowed it down further. Typically, he said, "if you have 80 degrees Fahrenheit entering the IT equipment in the cold aisle, you will have 100 to 105 degrees Fahrenheit leaving in the hot aisle. All of these values are functions of how much [...]

With the When spammers go to war: Behind the Spamhaus DDoS, DDoS (Distributed Denial of Service) attacks have been discussed widely on a number of news and technical blogs. While discussion has been greatly overzealous in some cases concerning this specific attack, the fact that this is preventable creates concern among many network professionals that we are not doing enough to inform people of the dangers. The attack used on Spamhaus had used two vulnerabilities that exist on at a number of small businesses to medium sized businesses as well as larger providers. The first and easiest at least in term of implementation is regulating open DNS resolvers. CYMRU has an easy to follow guide on both BIND and Microsoft’s server on their website: http://www.team-cymru.org/Services/Resolvers/instructions.html By limiting open recursive DNS servers on the internet, we will simply stop one type of attack however. The root cause of the attacks is from IP Spoofing attacks, which can be a bit more difficult to implement. Network Ingress Filtering has been considered a best current practice since May of 200, and is listed at the IETF’s website here: Network Ingress Filtering Defeating Denial of Service Attacks The most common way to implement BCP38 is through unicast reverse packet forwarding (uRFP) in most commercial routers with up to date firmware. This is mainly used when the router has a single connection to the internet. When you have multiple connections however, traffic can return from different paths so design considerations should be made on where to implement BCP38. For more information and actual implementation, I would suggest checking What's BCP38?. At the current time the site is not complete, but I suspect this will have the most up to date [...]
Power Capacity Planning for Data Center Colocation. Power compromises a large percentage of the data center’s costs and understanding your power requirements will help determine what size circuits you will need to order. Server manufactures may provide different power figures like max, startup, and running wattage per server configuration. Max wattage, also known as Power Supply Wattage is the maximum wattage the power supply can provide to the server. Many times the server may have two power supplies for redundancy, thus max load is usually calculated to run with one power supply. Running loads are what is typically used to calculate power needs. Startup load may run about 20% higher than the running load. For power draw calculations best practices would be to add 20% to your calculated running load. For example a server that averages a 200W running load should have a budget load of 240W to estimate max load during peak operations and planned server reboots. See the chart below. The following example uses a 20amp 120V circuit breaker. Accepting that the 20amp breaker has a potential of tripping at 80% or 16amps, it gives a trip point that you should be below. How far below is subjective; and due to budgetary factors, many try to push the circuits to maximum capacity without the breaker tripping. So what is safe for your mission critical environment? 50%, 60% 70% 80% of a circuit? Let’s assume you want to maximize the circuit and leave 20% power margin available for high server loads and planned server reboots. For calculation purposes we will convert amps to watts. (120V x Amps = Watts) or (120V x 16amps = 1,920Watts). If you plan to leave 20% safe ramp-up margin [...]
License: Creative Commons image source Before fiber-optic cables were introduced, communication networks were constructed solely of copper wiring. Since the introduction of fiber-optic cables, we are beginning to see more networks being constructed of them. As fiber-optics is finding its way in more places around the globe, it is truly revolutionizing the way we communicate with one another. Data Transmition is Quicker Than Ever Modern fiber-optic cables can transmit several terabits of data per second whereas copper wires are not able to transmit data even close to that speed. Traditional copper wires can only transmit as much as 2.5 megabits each second. Because fiber-optics can transmit data at such fast rates, Internet users can enjoy even greater amounts of bandwidth, and people can hear one another more clearly when teleconferencing and making phone calls. More People Have Access to Quality Telecommunication Services Since fiber-optic cables are cheaper and easier to deploy then the traditional copper wiring, more people in rural areas are able to enjoy quality telecommunication services. No longer are these people going to be restricted to satellite television that goes out when it rains or dialup Internet that crawls slower than the speed of a turtle. As more rural areas are connected to major networks, we are beginning to see an increase in subscribers to high speed Internet and cable TV. Less Interference Traditional copper wires are vulnerable to magnetism. When anything magnetic comes anywhere close to these wires, there is interference in the signals. This will explain why people sometimes have static or interference while they are on phone calls. Fiber-optic cables do have metal components; however, these components are not used to carry the signal. So, users can enjoy [...]
Courtesy of dnetit.com VoIP or Voice over Internet Protocol involves the transfer of voice – as in a phone call – over the internet to a specific IP address. This facilitates verbal communication between two or more parties. VoIP termination refers to a service that provides call facilities to a number of global destinations either under a subscription model or on a pay-as-you-go basis. The term VoIP termination refers to the end-point, or destination of the call, usually by a public switched telephone network, or PSTN. This type of service may be provided either as a bundled package or as a standalone service. Who uses VoIP termination? The number of service providers for VoIP termination has already grown a tremendous extent thanks to the competitive pricing being offered to businesses of virtually any size. Services are also offered to VoIP providers, who then resell the service packaged with their own VoIP interface solution for originating the call. This type of service is typically sold as a turnkey solution for call-centers and other similar support units. From basic features for small and medium businesses to robust packages for larger companies, VoIP termination services are typically flexible within certain parameters. VoIP termination services are also sold at per-minute or wholesale rates to independent software providers who want to integrate voice into mobile applications. Additionally, they are also sold to calling card operators that cater to specific or global destinations required by their users. What does it cost? Depending on the call origination location and the destination country, VoIP termination services may be offered for as little as 0.0029 cents per minute (for VoIP termination in the United States, for example). VoIP providers may be offered [...]
It seems like everyone's a geek these days, and it's not easy anymore to decide what kind of geek someone is. When you head to a convention or even when you are just getting to know someone, it can be very handy to figure out what kind of geek someone is before you proceed. Consider the fact that they might be a pop culture geek. Pop culture geeks are all about modern media and celebrities. They may be incredibly, creepily current on the lives of the Kardishans and they may have whole episodes of their favorite television show memorizes. Compare this with a cosplay geek, who's all about making costumes. Though cosplay geeks are most famous in the anime fandoms, you'll find that the tradition goes back to people dressing in Star Trek uniforms. You can spot the cosplay geek by looking for the deep purple circles under their eyes that they acquired after a long, long night of careful stitching. Source: Best Colleges Online
Now more than ever, having a secure and reliable connection to the internet is essential for running your business. Ten years ago you may have been able to survive a day or two without internet access, but today that is close to impossible. Whether you are receiving orders through your website, or relying on email for business communications, your revenue depends on maintaining an online presence. This makes choosing a commercial internet service provider a crucial decision. Here are some things to consider before you begin comparing companies. Technical Support The first thing you should ask any ISP provider is: How fast can you diagnose and solve problems? Obviously there are a lot of factors that go into that answer, but what you want to hear is a confident description of their support system. Every company out there is going to tell you that customer service is their number one priority. This might even be true, but service is not nearly as important as support. Would you rather chat with a friendly service representative, who has no clue on how to fix your problem, or would you prefer to speak with a tech geek that may not have the best social skills, but can get you back online in a few minutes? Connection Speed When you begin comparing providers you’ll find that companies use a lot of different statistics to sell you on their service. The thing is, these numbers mean very little unless you understand the benchmark for connection speed. You should be looking for download speeds in the neighborhood of 100 Mbps and upload speeds of at least 15 Mbps. This pretty much eliminates DSL services from consideration. Just remember that it doesn’t [...]
