Update: VMware NSX in Redundant L3-only Data Center Fabric

Short update for those that read the original blog post: it turns out that the answer to the question “Is it possible to run VMware NSX on redundantly-connected hosts in a pure L3 data center fabric?” is still NO.

VTEPs from different ESXi hosts can be in different subnets, but while a single ESXi host might have multiple VTEPs, the only supported way to use them is to put them in the same subnet. I removed the original blog post.

A huge thank you to everyone who pushed me with their comments and emails to find the correct answer.

BGPstream and The Curious Case of AS12389

The world of BGP routing is a fascinating place with lots of interesting BGP events happening every day. It can be challenging to keep track of it all and so two years ago we started the BGPstream website where we keep track of large scale outages and BGP hijacks. We list the events, basic info and visualize it with one of my favorite tools: BGPlay. For those who keep an eye on @bgpstream , you probably noticed a curious series of BGP hijacks today all by the same Autonomous system affecting many well known networks.

Starting at April 26 22:36 UTC till approximately 22:43 UTC AS12389 (PJSC Rostelecom) started to originate 50 prefixes for numerous other Autonomous systems. The 50 hijacked prefixes included 37 unique autonomous systems and the complete list of affected networks can be found below. If your organization is in this list feel free to reach out and we can provide more details if needed. Keep in mind that many of these hijacks are already published on BGPstream.com as well.

So back to this incident, what happened here? What makes the list of affected networks ‘curious’ is the high number of financial institutions such as for example:  MasterCard,Visa, Fortis,Alfa-Bank,card complete Continue reading

Samsung will launch new flagship smartphone months after Galaxy S8

Samsung Electronics said Thursday it was planning to launch in the second half of this year a new flagship phone, leading to speculation that the company is planning an alternative to the ill-fated Galaxy Note7 that had to be recalled last year.The launch of a new flagship smartphone this year and continuing sales of the Galaxy S8 and S8+ will help Samsung counter Apple’s launch of a new version of its iPhone. Apple usually unveils new phones in September."Samsung does announce a S series phone in the first half of the year and a Note series in the second half," said Kiranjeet Kaur, research manager for client devices at IDC Asia/Pacific. "So I am not sure if Samsung is alluding to the next Note or if they want to introduce a new series to avoid any questions or doubts that may arise because of the Note7 debacle."To read this article in full or to leave a comment, please click here

How to check your Uber rating

One of the brilliant things about Uber, and Lyft for that matter, is that it allows riders to rank drivers and for drivers, in turn, to rank passengers. This is a clever way to not only ensure that drivers are up to the task, but to also to provide users with an incentive to refrain from unruly behavior.Historically, Uber has allowed users to check what their own personal rating is, though doing so often required users to jump through a few hoops. Earlier today, however, Uber made the entire process much more seamless. Which is to say, if you're curious as to what Uber drivers think of you as a passenger, it's now easier than ever to access that information.To read this article in full or to leave a comment, please click here

Data center network monitoring best practices part 1: Metrics and alerts

One of the least loved areas of any data center network is monitoring. This is ironic because at its core, the network has two goals: 1) Get packets from A to B 2) Make sure packets got from A to B. It is not uncommon in the deployments I’ve seen for the monitoring budget to be effectively $0, and generally, an organization’s budget also reflects their priorities. Despite spending thousands, or even hundreds of thousands, of dollars on networking equipment to facilitate goal #1 from above, there is often little money, thought and time spent in pursuit of Goal #2. In the next several paragraphs I’ll go into some basic data center network monitoring best practices that will work with any budget.

It is not hard to see why monitoring the data center network can be a daunting task. Monitoring your network, just like designing your network, takes a conscious plan of action. Tooling in the monitoring space today is highly fragmented with over 100+ “best of breed” tools that each accommodate a specific use case. Just evaluating all the tools would be a full time job.

Ransomware attacks are taking a greater toll on victim’s wallets

The hackers spreading ransomware are getting greedier. In 2016, the average ransom demand to free computers hit with the infection rose to US$1,077, up from $294 the year before, according to security firm Symantec.“Attackers clearly think that there’s more to be squeezed from victims,” Symantec said in a Wednesday report.In addition, the security firm has been detecting more ransomware infection attempts. In 2016, the figure jumped by 36 percent from the year prior.  That doesn’t bode well for the public. Ransomware is notorious for taking over computers, and essentially holding them hostage. To do so, the malicious coding encrypts all the data inside, and then demands a fee, usually in bitcoin, in exchange for releasing the machine.To read this article in full or to leave a comment, please click here

IDG Contributor Network: AI goes to the movies to identify content you will want to watch

The digital technology and media and entertainment industries are beginning to come together to solve a common problem—how to extract, unlock, harness and make better use of the massive amounts of video content and data they produce. Anyone who has ever appeared in or produced a movie, commercial or business video is aware that many times a good portion of the footage winds up on the proverbial cutting room floor. The same is true of digital data. It is estimated that more than 80 percent of enterprise data is considered “dark”—created but never used.+ Also on Network World: Machine learning proves its worth to business + What if there were a way to pick up this data equivalent of cutting room discards and turn them into new assets? What if technologies such as IBM Watson could work with video editors to unearth data treasures that benefit and excite both producers and audiences? Sounds like the plot to a blockbuster movie, but it is now more fact than fiction.To read this article in full or to leave a comment, please click here

Worth Reading: Learning blockchains

A blockchain is a digital ledger of records that’s arranged in chunks of data called blocks. These blocks then link with one another through a cryptographic validation known as a hashing function. Linked together, these blocks form an unbroken chain — a blockchain.
The reason that this type of data structure is useful for things like cryptocurrencies is decentralization, meaning the records inside this chain aren’t stored in any single location, are accessible by everyone, and are immutable by any one party. —Free Code Camp

Avoid manually installing Windows 10 Creators Update

The Windows 10 Creators Update began rolling out on April 11, but impatient users could do their own upgrade as early as April 5 thanks to a utility called the Update Assistant, which downloaded it and installed the update for you.A lot of people jumped on this offer, and thanks to a few blow-ups, Microsoft has found some problems with the update and now advises users not to manually install the Creators Update and instead wait until it’s automatically offered for Windows Update.+ Also on Network World: 10 hidden features in the new Windows 10 Creators Update + The reason for all this rather late call for caution is that Microsoft wants to iron out any issues for specific hardware configurations. It started the rollout for newer devices that were less likely to have problems. To read this article in full or to leave a comment, please click here

How HP reclaimed the title of world’s top PC maker from Lenovo

In late 2015, HP was reborn as a PC maker following a split of its parent organization, Hewlett-Packard. At the time, HP was a lost cause, and its double-digit decline in PC shipments was a main reason for the split.The new HP then set out to reclaim its spot as the world's top PC maker from Lenovo, a title it lost in 2013. It reached the goal in the first quarter of 2017, during which its PC shipments grew by 13.1 percent year over year.A series of cool products and decisions to cut off low-margin products helped HP return to the top. Lenovo's struggles also played a part, but HP's strong performance in North America was a deciding factor, IDC said.To read this article in full or to leave a comment, please click here

How to derive real, actionable insights from your data lake: Five best practices

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.More businesses are embarking on data lake initiatives than ever before, yet Gartnerpredicts 90% of deployed data lakes will be useless through 2018 as they’re overwhelmed with data with no clear use cases. Organizations may see the value of having a single repository to house all enterprise data, but lack the resources, knowledge and processes to ensure the data in the lake is of good quality and actually useful to the business.  To truly leverage your organization’s data lake to derive real, actionable insights, there are five best practices to keep in mind:To read this article in full or to leave a comment, please click here

Microsoft adds another layer to the Windows 10 patching onion

Microsoft yesterday added another update cycle to Windows 10's monthly patching, saying that the new collection of non-security-only fixes would give corporate customers the "increased flexibility" they had demanded.On Monday, Michael Niehaus, director of Windows 10 product marketing, announced the new monthly update, saying that the company would initially issue it only to customers running 1703, the upgrade also known as Creators Update, which launched earlier this month."We will routinely offer one (or sometimes more than one) additional update each month," Niehaus wrote in a post to a company blog. "These additional cumulative updates will contain only new non-security updates" [emphasis added].To read this article in full or to leave a comment, please click here
