Why Is Stretched ACI Infinitely Better than OTV?

Eluehike Chedu asked an interesting question after my explanation of why stretched ACI fabric (or alternatives, see below) is the least horrible way of stretching a subnet: What about OTV?

Time to go back to the basics. As Dinesh Dutt explained in our Routing on Hosts webinar, there are (at least) three reasons why people want to see stretched subnets:

Last ditch iPhone 7 rumor rollup: EarPod, 256GB storage speculation gains steam

Apple's confirmation that it will be making news on Sept. 7 means that our regular iPhone 7 rumor roundups are winding down, but you didn't expect the rumors to dry up before the big day, did you?Just this week, the following fresh scuttlebutt has surfaced, more or less confirming a couple of the most persistent rumors about the next big iOS devices:*Mashable cites a Dutch site that posted a technical document for the iPhone 7 Plus describing "EarPods with Lightning connector," adding support to the strong rumor that Apple is ditching the traditional 3.5mm headphone jack.  A Lightning-to-headphone jack adapter and Lightning-to-USB cable connector are also mentioned.To read this article in full or to leave a comment, please click here

iPhone 7 Plus may come with a 256GB storage option

One of the more interesting iPhone 7 rumors suggests that Apple’s next-gen iPhone will come with a 256GB storage options. While 256GB of storage may seem excessive, it perhaps stands to reason that the iPhone 7 Plus -- on account of its dual camera system which will take presumably large high-res photos -- will need more storage than many are anticipating.That said, an interesting iPhone 7 leak hit the Apple blogosphere earlier today when a spec sheet purporting to be for the iPhone 7 was posted on the Chinese microblogging website Weibo. As evidenced via the photo below, a 256GB iPhone 7 Plus model may be announced next week at Apple’s special media event.To read this article in full or to leave a comment, please click here

VMware Expands NSX Use Cases With Cross-Cloud

Worth Reading: Open Flow Controller Performance

OpenFlow’s architecture is inefficient, and caps performance while sucking unnecessary power. That’s the conclusion of a bunch of Comp. Sci boffins from researchers at Australian brain box Data61 and Sydney University, who assessed four major OpenFlow controllers – NOX, Maestro, Floodlight and Beacon. Their paper is at Arxiv. Poor old OpenDaylight was also tested but not reported: “the performance [was] too low to provide any insightful comparison”. To cut to the chase: none of the controllers tested got anywhere close to line speed, whether running on a network processor (based on Tilera chips), or on a Xeon E5-2450-based server (more on the configurations later). —The Register

Microsoft conscripts upload bandwidth in Windows 10’s latest Insider update

Microsoft today updated the Windows 10 beta, switching on a controversial technology that commandeers users' upload bandwidth to shift some responsibility for updating from the company's own servers.Build 14915 was released earlier Wednesday to participants in the Windows Insider "Fast" track.The notable change highlighted by Dona Sarkar, the software engineer who acts as the public face of Insider, was the enabling of Windows 10's "Delivery Optimization" technology.INSIDER Review: Enterprise guide to Windows 10 Delivery Optimization, formally dubbed "Windows Update Delivery Optimization" (WUDO) by Microsoft, was part of Windows 10 from the get-go. But it was only switched on as of the November 2015 upgrade, which was pegged as 1511. Insider builds of Windows 10, however, were exempt until now.To read this article in full or to leave a comment, please click here

Lenovo kicks off IFA with four new notebook/tablet offerings

People who feel that there’s “nothing new to see” in the world of notebooks and tablets should take a look at what Lenovo announced today. Ahead of the IFA show in Berlin, the company announced four new offerings, highlighting design upgrades and features that challenge users to think about what can be done with a computer. That’s no small feat in today’s technology device world, where everything often looks the same, with just a different label slapped on the cover.Here’s a quick look at the announcements:Yoga Book This 2-in-1 device takes its Book moniker seriously - when spread out flat, the device looks a lot more like a book than a notebook or even a tablet (see photo above). The Yoga Book features a “halo keyboard”, which is a full touch screen backlit keyboard that integrates software and hardware into the interface. The glass touch screen includes an anti-glare coating to create a touch-typing experience, which should be helpful since there are no physical keys. Instead, it displays as a solid white outline on the Yoga Book’s second panel, and it’s only on when the user needs a keyboard. Software is also included that “learns about and adapts Continue reading

The company behind Hillary Clinton’s erased emails is riding high

A small open source firm behind the erasure of Hillary Clinton's personal email server is enjoying a lot of free publicity thanks to the investigation into the server's contents.

Moto Z Play with Hasselblad True Zoom: Finally a smartphone and camera worth talking about

Smartphone reviewers, including myself, write reviews that read more like Robert Parker’s reviews of expensive wines from great vineyards. Oenophiles and smartphone reviewers alike often meander through subtle differences that most consumers don’t have the palette to distinguish. The Moto Z with the Hasselblad True Zoom Moto Mod add-on module, however, allows smartphone reviewers, for the first time in a long time, to stop meandering with subtleties and gives them something tangible to write about.To read this article in full or to leave a comment, please click here

AI, Machine Learning, and The Hitchhiker’s Guide

I had a great conversation with Ed Horley (@EHorley) and Patrick Hubbard (@FerventGeek) last night around new technologies. We were waxing intellectual about all things related to advances in analytics and intelligence. There’s been more than a few questions here at VMworld 2016 about the roles that machine learning and artificial intelligence will play in the future of IT. But during the conversation with Ed and Patrick, I finally hit on the perfect analogy for machine learning and artificial intelligence (AI). It’s pretty easy to follow along, so don’t panic.

The Answer

Machine learning is an amazing technology. It can extrapolate patterns in large data sets and provide insight from seemingly random things. It can also teach machines to think about problems and find solutions. Rather than go back to the tired Target big data example, I much prefer this example of a computer learning to play Super Mario World:

You can see how the algorithms learn how to play the game and find newer, better paths throughout the level. One of the things that’s always struck me about the computer’s decision skills is how early it learned that spin jumps provide more benefit than regular Continue reading
