America’s data centers are getting a lot more efficient

U.S. data centers have used about the same amount of energy annually over the past five years or so, despite substantial growth in the sector, according to a new report published by scientists at Lawrence Berkeley National Laboratory.In the Berkeley Lab’s previous analysis, which was presented to Congress in 2008, it was found that energy usage by data centers was quadrupling every decade – an unsurprising figure given the explosive overall growth in the sector.

IoT botnet: 25,513 CCTV cameras used in crushing DDoS attacks

Over 25,000 hacked internet-connected CCTV cameras are being used for a denial-of-service botnet, according to researchers from the security firm Sucuri.The discovery came after Sucuri mitigated a DDoS attack against a jewelry store site; it had been generating 35,000 HTTP requests per second. But after bringing the website back up, researchers said the attacks increased to nearly 50,000 HTTP requests per second. When the attack continued for days, the researchers discovered the attack botnet was leveraging only IoT CCTV devices, which were located across the globe.Although this is not the first CCTV-based DDoS botnet discovered (900 had been used in attacks last year), it is the largest yet to be discovered.To read this article in full or to leave a comment, please click here

Will Dell Networking Wither Away?

The behemoth merger of Dell and EMC is nearing conclusion. The first week of August is the target date for the final wrap up of all the financial and legal parts of the acquisition. After that is done, the long task of analyzing product lines and finding a way to reduce complexity and product sprawl begins. We’ve already seen the spin out of Quest and Sonicwall into a separate entity to raise cash for the final stretch of the acquisition. No doubt other storage and compute products are going to face a go/no go decision in the future. But one product line which is in real danger of disappearing is networking.

Whither Whitebox?

The first indicator of the problems with Dell and networking comes from whitebox switching. Dell released OS 10 earlier this year as a way to capitalize on the growing market of free operating systems running on commodity hardware. Right now, OS 10 can run on Dell equipment. In the future, they are hoping to spread it out to whitebox devices. That assumes that soon you’ll see Dell branded OSes running on switches purchased from non-Dell sources booting with ONIE.

Once OS 10 pushes forward, what does that Continue reading

Cisco Connects With SGI For Big NUMA Iron

When supercomputer maker SGI tweaked its NUMA server technology to try to pursue sales in the datacenter, the plan was not to go it alone but rather to partner with the makers of workhorse Xeon servers that did not – and would not – make their own big iron but who nonetheless want to sell high-end machines to their customers.

This, company officials have said all along, is the only way that SGI, which is quite a bit smaller than many of the tier one server makers, can reach the total addressable market that the company has forecast for its …

Cloud computing slows energy demand, U.S. says

Ten years ago, power usage at data centers was growing at an unsustainable rate, soaring 24% from 2005 to 2010. But a shift to virtualization, cloud computing and improved data center management is reducing energy demand.According to a new study, data center energy use is expected to increase just 4% from 2014 to 2020, despite growing demand for computing resources.Total data center electricity usage in the U.S., which includes powering servers, storage, networking and the infrastructure to support it, was at 70 billion kWh (kilowatt hours) in 2014, representing 1.8% of total U.S. electricity consumption.ALSO ON NETWORK WORLD: Whatever happened to Green IT? Based on current trends, data centers are expected to consume approximately 73 billion kWh in 2020, becoming nearly flat over the next four years. "Growth in data center energy consumption has slowed drastically since the previous decade," according to a study by the U.S. Department of Energy's Lawrence Berkeley National Laboratory. "However, demand for computations and the amount of productivity performed by data centers continues to rise at substantial rates."To read this article in full or to leave a comment, please click here

Backblaze wants to eliminate tape-based storage

Online backup company Backblaze made waves last year when it announced a beta test last year of B2, a new public cloud storage service that would be cheaper than competing offerings from Amazon and Microsoft. B2 has now exited beta with some new features that may make it more appealing to business users. It now has a service level agreement guaranteeing 99.9 percent uptime for all data stored within it, matching the baseline offerings from Amazon Web Services’ S3 and Microsoft Azure’s Blob Storage service. In addition, users can now purchase expanded support from Backblaze, which will give them guaranteed rapid responses to support questions and – at the highest level – access to a phone number for around-the-clock support.To read this article in full or to leave a comment, please click here

5 steps for securing the IoT using Aruba ClearPass

Historically the Internet of Things (IoT) has been much more hype than substance. Sure, there have been a few verticals such as oil and gas and mining that have embraced the trend, but those vertical have been active in IoT since it was known as machine to machine (M2M).Now, however, we sit on the precipice of IoT exploding. I’ve seen projections that by 2025, anywhere from 50 billion to 200 billion new devices will be added to the network. Which is right? Doesn’t really matter. The main point is that we’re going to see a lot devices connected over the next 10 years, and businesses need to be ready. + Also on Network World: Experts to IoT makers: Bake in security +To read this article in full or to leave a comment, please click here

FBI expansion of surveillance powers meets obstacle

A move in the Senate to provide enhanced surveillance powers to the FBI through the use of National Security Letters met a hurdle Monday after Senator Ron Wyden placed a hold on the 2017 Intelligence Authorization bill over the controversial provisions.Wyden’s hold is a a measure by which a senator or group of senators can prevent a motion from reaching a vote.Tech companies and industry and civil rights groups are opposed to what is seen as a wider push by the Senate to increase the scope of the NSLs, which would allow the government to collect Internet records such as browsing history, email metadata, and location information through administrative orders and without court approval.To read this article in full or to leave a comment, please click here

Tensions rise over LTE using Wi-Fi channels

The fight over LTE networks sharing channels with Wi-Fi appears to be heating up.The Wi-Fi Alliance says that by September there will be a way to test whether an LTE device can get along with Wi-Fi. But Qualcomm, one of the biggest backers of LTE-U (LTE-Unlicensed), is demanding those tests immediately.The latest disagreement arose after a workshop held last Wednesday, the latest in a series aimed at crafting a test plan for coexistence between the two technologies. That test plan, which is designed for new products that use LTE in unlicensed bands, will be finished and verified by late September, WFA said.That's at least a month later than some earlier forecasts. Test development has taken a long time because it's an unprecedented project and the tests still need to be validated, WFA marketing vice president Kevin Robinson said.To read this article in full or to leave a comment, please click here
