What is a SAN and how does it differ from NAS?

A storage area network (SAN) is a dedicated, high-speed network that provides access to block-level storage. SANs were adopted to improve application availability and performance by segregating storage traffic from the rest of the LAN. SANs enable enterprises to more easily allocate and manage storage resources, achieving better efficiency. “Instead of having isolated storage capacities across different servers, you can share a pool of capacity across a bunch of different workloads and carve it up as you need. It’s easier to protect, it’s easier to manage,” says Scott Sinclair, senior analyst with Enterprise Strategy Group.To read this article in full, please click here

Juniper’s new products help prepare networks for hybrid, multi-cloud

Earlier this week, Juniper Networks announced a bevvy of new networking products. (Note: Juniper Networks is a client of ZK Research.) In his blog post about the products, Andy Patrizio did an effective job covering the basics of the news. But left out some important points, and I wanted to make sure those got called out, including Juniper's tagline “multi-cloud ready."  Hybrid, multi-cloud is inevitable  As I’ve pointed out in many of my posts, hybrid multi-cloud environments are inevitable for most organizations. Small businesses may be able to build an IT strategy that is all public cloud, but any large company is going to choose a mix of private and public clouds.To read this article in full, please click here

Short Take: The Broadcom SDKLT Announcement

My first short take at The Network Collective is up discussing the Broadcom SDKLT announcement. Does this really mean the end of vendors or network engineering? You can guess my answer, or you can watch the video and hear it for yourself.

Future Thinking: Niel Harper on Cyber Threats

In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. In February 2018, we interviewed two stakeholders – Cyrating, a cybersecurity ratings agency, and Niel Harper, Senior Manager, Next Generation Leaders at the Internet Society – to hear their different perspectives on the forces shaping the Internet.

Niel Harper is a Young Global Leader at the World Economic Forum. He has more than 20 years of experience in the areas of telecoms management, cybersecurity, IT governance and strategy, ICT policy research and advisory services, and program management. (You can read Cyrating’s interview here).

The Internet Society: Experts predict an increase of frequency and impact of cyberattacks. What form are they likely to take in the future?

Niel Harper: In the foreseeable future, attackers are likely to fall under three categories: organized criminals seeking to profit from malicious online activities, online protesters (also known as hacktivists), and governments who target their own citizens or target other governments, whether for cyberespionage or cyberwarfare.

Criminals will continue to become more organized, selling Continue reading

Lenovo Sees Expanding Market for Dense Water-Cooled HPC

The demands for more compute resources, power and density in HPC environments is fueling the need for innovative ways to cool datacenters that are churning through petabyte levels of data to run modern simulation workloads that touch on everything from healthcare and climate change to space exploration and oil and gas initiatives.

The top cooling technologies for most datacenters are air and chilled water. However, Lenovo is promoting its latest warm-water cooling system for HPC clusters with its ThinkSystem SD650 systems that the company says will lower datacenter power consumption by 30 to 40 percent of the more traditional cooling …

Wireless Doctors

Wireless is a complicated thing. Even when you try to distill it down to networking basics on the wired side of the access point, you still have a very hard problem to solve on the radio side. Even I’ve talked in the past about how wireless is now considered a “solved” problem. But, the more I interact with wireless professionals and the more I think about the problem, the issue isn’t that IT departments think wireless is solved, it’s that they don’t appreciate the value of a specialist.

The Last Place Doctor

There’s an old joke that goes, “What do you call the person that graduated last in their medical school class? Doctor.” Professionals spend a lot of their time learning a tradecraft and practicing it to get better. And it’s not just doctors. So do plumbers, electricians, and teachers. Anyone that has ever tried to do any of these trades will tell you that the basics are capable of being figured out by the average non-professional, but the details are a huge leap.

You’d never assume that being able to put on a Band-Aid on a scrape would qualify you to do brain surgery. Or that changing a Continue reading

Future Thinking: Cyrating on Cyber Threats

In 2017, the Internet Society unveiled the 2017 Global Internet Report: Paths to Our Digital Future. The interactive report identifies the drivers affecting tomorrow’s Internet and their impact on Media & Society, Digital Divides, and Personal Rights & Freedoms. In February 2018, we interviewed two stakeholders – Cyrating, a cybersecurity ratings agency, and Niel Harper, Senior Manager, Next Generation Leaders at the Internet Society – to hear their different perspectives on the forces shaping the Internet’s future.

Cyrating is the first cybersecurity ratings agency anchored in Europe, and helps forward-thinking organizations maximize their cybersecurity performance and investments. It identifies potential for improvement, benchmarks it against industry best practices, and provides standardized cybersecurity metrics.

#PressForProgress - International Women’s Day 2018 | A Cloudflare & Branch Event

Almost a year ago, I began my journey in the tech industry at a growing company called Cloudflare. I’m a 30-something paralegal and although I didn’t know how to write code (yet), I was highly motivated and ready to crush. I had worked hard for the previous two years, focused on joining a thriving company where I could grow my intelligence, further develop my skill set and work alongside successful professionals. And finally, my hard work paid off; I landed the job at Cloudflare and booked a seat on the rocket ship.

After the initial whirlwind that accompanies this fast-paced field subsided, motivation, inspiration, success, momentum and endurance began to flood my neurons. I loved the inner workings of a successful startup, felt the good and bad of the tech industry, related to and admired the female executives and most importantly, wanted to give something back to the community that adopted me.

During a routine chat with my dad, I pitched what I thought was a crazy idea. Crazy because I was so used to being told “no” at previous jobs, used to not having my ideas taken seriously, and also used to not Continue reading

Big Changes Ahead for Core Internet Protocols – IETF Journal

Excellent summary of what seems to be poorly understood. IPv6 is going nowhere slowly but the higher level protocols are changing today. Now, significant changes to the core Internet protocols are underway. While they are intended to be compatible with the Internet at large (since they won’t get adoption otherwise), they might be disruptive to […]

IDG Contributor Network: Emerging blockchain-based distribution storage market and its effect on cloud computing

The blockchain industry, historically tied directly to cryptocurrency, has made a right turn in recent months. It has extended its legion of users to offer distributed storage. This threatens to undercut the pricing market established by cloud computing storage giants like AWS and Dropbox.How it works Blockchain-based distribution storage is centered around the idea that there are large amounts of unused storage space on the hard drives of people all over the world. Using cryptocurrency as an incentive, blockchain distribution companies monetize that storage space for their members. It is an upgraded version of what BitTorrent was in the early 2000s, using peer-to-peer (P2P) networks to form an aggregate of computer resources. But with cryptocurrencies built in to blockchains as a method of payment, users have a monetary incentive to offer up their unused data space to consumers.  Because of its extreme distribution of data - known as sharding - blockchain-based storage has the potential to be more secure than cloud-based storage. And by using the in-place hardware maintained by others, it can drastically cut the cost for the end-user.    To read this article in full, please click here

IoT: Sensor-as-a-service, run by blockchain, is coming

Telecommunications equipment maker Nokia has launched a turnkey, sensor-as-a-service offering for Internet of Things (IoT) networks.The idea behind the product is to provide a way for mobile network operators (MNOs), many of which use Nokia cell site equipment, to monetize existing infrastructure, such as towers, by selling live environmental sensor data to cities and others.Read also: When IoT met blockchain | Sign up: Receive daily tech news updates MNOs increasingly are looking for new revenue sources as consumer smartphone growth plateaus. And cities need to adopt digital strategies to manage assets, increase efficiencies, and keep stakeholders happy. For example, they need granular real-time data about public transportation flow and air quality to ensure they comply with regulations—that the traffic is flowing and no illegal garbage is burning.To read this article in full, please click here

Big Red Button for Network Automation

A while ago I was enjoying a few beers with a longtime friend of mine who happens to be running the networking team for one of the rare companies that understands how infrastructure should be built and operated.

Of course, I had to ask him what he thinks about the imminent death of CLI and all-encompassing automatic provisioning from some central orchestration system. Here’s the gist of his response:
