When it comes to hyperconverged infrastructure, the hardware matters

At Nutanix's .NEXT user conference last week, the company certainly flexed its software muscles with a cornucopia of new products and a roadmap to becoming the next big enterprise platform vendor. To achieve this status, Nutanix has shifted to selling software and letting its customers run its stack on their preferred hardware platform.There is currently a wide range of hardware partners supporting Nutanix, including Lenovo, IBM, and HPE. However, the vendor that has done perhaps the best job at providing the widest range of options for Nutanix customers is Dell EMC.To read this article in full, please click here

Will Huawei become a pawn in a high-stakes U.S.-China technology war?

The Justice Department investigation into Huawei recalls a similar probe into whether Shenzhen rival ZTE broke U.S. sanctions by exporting devices containing American components to Iran. ZTE was found guilty last year not only of breaking the sanctions, which resulted in an $892 million fine, but of breaking the settlement deal’s terms by failing to punish those involved.To read this article in full, please click here(Insider Story)

GPUs: Designed for gaming now crucial to HPC and AI

It’s rare to see a processor find great success outside of the area it was intended for, but that’s exactly what has happened to the graphics processing unit (GPU). A chip originally intended to speed up gaming graphics and nothing more now powers everything from Adobe Premier and databases to high-performance computing (HPC) and artificial intelligence (AI).GPUs are now offered in servers from every major OEM plus off-brand vendors like Supermicro, but they aren’t doing graphics acceleration. That’s because the GPU is in essence a giant math co-processor, now being used to perform computation-intensive work ranging from 3D simulations to medical imaging to financial modelingTo read this article in full, please click here

Is OSPF or IS-IS Good Enough for My Data Center?

Our good friend mr. Anonymous has too many buzzwords and opinions in his repertoire, at least based on this comment he left on my Using 4-byte AS Numbers with EVPN blog post:

But IGPs don't scale well (as you might have heard) except for RIFT and Openfabric. The others are trying to do ECMP based on BGP.

Should you be worried about OSPF or IS-IS scalability when building your data center fabric? Short answer: most probably not. Before diving into a lengthy explanation let's give our dear friend some homework.

Don’t Reply To Everything

I recently came across a simple idea that is having a positive impact on productivity. That idea is to not reply to everything. While this can be applied to social media broadly, I’m focused on email management here.

For me, not replying is more difficult than it sounds. I am a personality type that doesn’t like loose ends. I like to meet other’s expectations, and have them think cuddly, happy thoughts about what a swell person I am. I know that when I send an email, I hope to get a response. Therefore, when I receive an e-mail, my natural inclination is to respond.

Too cuddly?

Now, I don’t feel I overly waste time on replying to email. I’ve improved my response technique over the years. I bring an e-mail thread to a conclusion as rapidly as possible by anticipating and proactively answering questions. That’s more time-consuming than a quick, lazy “back to you” response, but saves time in the long run.

However, an advance on the proactive reply is never replying at all. Not responding is the ultimate way to bring an email thread to a conclusion.

You’re So Rude

On the surface, ignoring inbox messages seems rude. However, Continue reading

The Enterprise of Thing’s troubling lack of security

When it comes to security and manageability, Enterprise of Things (EoT) devices must have far more stringent requirements than consumer IoT devices, which often have virtually no built-in security. Indeed, enterprise use of consumer-grade IoT is highly risky.Making the matter even more urgent is the growing number of deployed EoT devices, which is expected to increase significantly over the next two to three years. (I estimate there will be more “things” in an enterprise than PC and mobile phone clients combined within three to four years.)To read this article in full, please click here

Innovative Licensing Approaches: Enabling Access in Hard-to-Reach Places Through Collaborative Partnerships

In the Republic of Georgia, high in the mountains of the Tusheti region, a community network has been built to bring faster Internet connectivity to those that did not have it. The story is compelling, not only for the determination of people to make sure that the Internet is available in one of the remotest places in the world, but also for their strong belief of what connecting to the Internet could bring to the people of Tusheti. “Tourism is a beacon of hope for us,” said Ia Buchaidze, who owns a local bakery, “and the Internet is very important for that.”

The project was a true collaborative partnership involving many parties: the Georgian Government, the Internet Society and its Georgia Chapter, the Small and Medium Telecom Operators Association of Georgia, LTD Freenet, and the Tusheti Development Fund (TDF). This network did not need a license, but it did need an authorization from the Georgian Government for it to be built and for the spectrum to be used. The objective was to provide access to a remote region through a locally-built and developed community network.

Similarly, in Mexico, a community network has been built in a remote and Continue reading
