The Next Generation Agile Data Center and the Birth of A Dynamic Network

At Plexxi we’re building a simply better network for the next era of IT to deliver agile data centers, enable scale-out applications and support distributed Cloud deployments.  In my prior blog, I discussed why the decades-old practice of pre-architecting, designing and implementing static network infrastructures wouldn’t support the dynamic needs of organizations moving forward. In this installment of my blog, I will review a case study from a large enterprise deploying an agile data center to meet their needs for the next generation.

I continue to spend a lot of time on the road, and I enjoy meeting with customers to make sure I stay on top of next generation data center networking requirements.  I recently visited a large enterprise that was experiencing scalability, management and performance problems with their existing data center network.  As the number of virtualized applications and corresponding virtual machines (VMs) grew in their data center, agility was actually decreasing rather than improving.  The data center was harder to manage due to application mobility and a lack of unified visibility across their virtual and physical environments.  In addition, their oversubscribed switches were experiencing capacity and buffering problems, caused in large part Continue reading

The Upload: Your tech news briefing for Tuesday, July 28

Samsung tipped to upstage Apple with August phone launchSamsung has sent out invitations to an event in New York next month that looks like it’s planned to be the coming out party for a new, larger version of its flagship Galaxy S6 edge smartphone. The S6 line has been a hot item but the company hasn’t been able to keep up with demand, and shortages of the smartphone may be a factor holding down Samsung’s quarterly earnings, to be reported on Thursday.Most Android phones can be hacked just by sending them a multimedia messageTo read this article in full or to leave a comment, please click here

Car and pedestrian collision? There’ll soon be an app for that

A safety system that ties cars and smartphones together to stop those heart-stopping near misses between cars and pedestrians could be standardized by the end of this year.The technology involves smartphones broadcasting data over a short-range radio channel to nearby cars, so the cars can determine if a collision is likely. Unlike today’s radar-based systems, this has the ability to warn around blind corners and can alert both the driver and pedestrian.It’s being developed by engineers at Honda and was demonstrated last week at the company’s new research and development center in Mountain View, in the heart of Silicon Valley.In the demonstration that took place in a parking lot, a car was slowly cruising a row looking for a space. Ahead, and unseen to the driver, a pedestrian was walking between a car and SUV while listening to music, and about to step into the path of the oncoming vehicle.To read this article in full or to leave a comment, please click here

Someday your phone may stop an oncoming car

Self-driving cars will try to avoid robot pedestrians in a simulated city as part of an effort to make real-world streets safer.M-City, a test facility that the University of Michigan opened this month in Ann Arbor, packs a range of street configurations and road conditions into a 32-acre (13-hectare) facility for testing emerging automotive technologies. The site includes stoplights, traffic circles, gravel and brick roadways and movable building facades. It will play host to some of the testing for vehicle-to-pedestrian (V2P) detection systems that Verizon Communications hopes to turn into a commercial reality.V2P uses DSRC (Dedicated Short Range Communications), the same radios as vehicle-to-vehicle technology that could prevent crashes between cars that approach each other unexpectedly around a blind corner. In the pedestrian safety system, the smartphones people carry would talk to specialized radios in cars or even just to drivers’ phones. Those wireless exchanges are part of a broader effort to prevent vehicle accidents that killed 30,000 people per year in the U.S., according to the National Highway Traffic Safety Administration (NHTSA). The agency estimates 14 percent of those accidents involve pedestrians.To read this article in full or to leave a comment, please click here

NSA will lose access to ‘historical’ phone surveillence data Nov. 29

The U.S. National Security Agency will lose access to the bulk telephone records data it has collected at the end of November, the Office of the Director of National Intelligence announced Monday.Congress voted in June to rein in the NSAs mass collection of U.S. phone metadata, which includes information such as the timing and location of calls. The Foreign Intelligence Surveillance Court then gave the NSA 180 days to wind the program down.To read this article in full or to leave a comment, please click here

Facebook opens Internet.org to more mobile operators

Facebook is inviting additional mobile operators to take part in Internet.org, its project to bring Internet access to poorly connected parts of the world.Internet.org turns one year old this week, and Facebook says it’s ready to scale the project to reach more people.The company is making it easier for more mobile operators to join the project by launching an online portal where they’ll find technical tools and best practices to help them get started.So far, Facebook has been working with about a dozen operators in 17 countries to provide an app that gives people free access to a set of basic Internet services.To read this article in full or to leave a comment, please click here

VTEP: Your High-throughput Bridge from Virtual to Physical

Speakers: Adam Johnson, VP of Business, Midokura and Leslie Carr, DevOps Engineer, Cumulus Networks

Abstract:  In this session, we will use a real-world case study to show how VXLAN tunnel endpoints (VTEPs) and VXLAN offloading can increase network throughput while reducing CPU overhead — overcoming two significant hurdles facing virtualized data centers.  We will demonstrate typical applications and workloads deployed on physical and virtualized machines.  On the network layer, the switches will utilize Continue reading

The weirdest, wackiest and coolest sci/tech stories of 2015 (so far!)

Your wackiestIn 2015 the science world has been dominated by space event – NASA’s flyby of Pluto and subsequent deluge of information about that dwarf planet. Then we have another NASA probe – Kepler – pointing out one closest-to-Earth planet discoveries to date. There have been tons of other interesting stories though regarding 3D printed cars, drones, high-tech singers and more.

Google to decouple Google+ from some of its sites

Google is severing the ties between its social network and other of its services, so that users will not need to log in to other sites like YouTube using a Google+ account.In the coming months, people will only need a standard Google account—not a Google+ account—to do things like share content, communicate with contacts, and create a YouTube channel, the company announced Monday. YouTube will be one of the first products to adopt the change.Since launching Google+ in 2011, the company has tried to integrate it into its various other properties, partly in an aim to unify people’s identities across them. But the integrations have not always gone smoothly. Google sparked outrage from users when in 2013 the company began requiring people to hold a Google+ account to post YouTube comments.To read this article in full or to leave a comment, please click here
