BrandPost: Delivering Best-in-Class Education Technology Without Breaking the Bank

Digital technology is driving fundamental changes in the educational process. As digital devices and the internet become an integral part of students’ lives, schools are finding they must support new learning solutions. Digital learning is a new constant in the school day.New digital solutions and technologies such as virtual/augmented reality, digital whiteboards, distance learning, personalized learning, artificial intelligence, and gamification are creating new demands on schools’ IT capabilities and infrastructure. And as these and other exciting new technologies come into regular use, many schools find they need to upgrade their server room into an “always-on,” flexible, and cost-efficient data center designed to support 21st century learning.To read this article in full, please click here

Understanding IPv6: Prepping For Solicited-Node Multicast (Part 5 of 7)

Solicited-node multicast: I stumbled and tripped a bunch over this one in the beginning.  Well, that isn’t 100% true. Admittedly, at first, I really just ignored it, which really got in the way of my understanding some of the fundamentals of Neighbor Discovery Protocol (NDP).

But before we jump into solicited-node multicast, let’s review link-local scope multicast addresses.

Multicast is all around you
Multicast is all around your current IPv4 network. You might not think so if you haven’t enabled IP multicast routing and PIM, but it’s there. Pretty much everywhere you turn, it’s there.

Let’s return to our RouterA/RouterB environment. But let’s have IPv4 only running right now, like probably a lot of your routers in your environment.

Show IP interface
This is often an overlooked command, which is a shame because there is a great deal of very useful information that is given in the output. For now, we’re going to focus on the line “multicast reserved groups joined” and ignore all the other lines.

See? Lots and lots of multicast! To be specific, lots of “Local Network Control Block (224.0.0.0 – 224.0.0.255 (224.0.0/24),” according to the Internet Continue reading

Which data center intrusion prevention systems are worth the investment? NSS Labs tests 5 DCIPS products

Performance is critical when evaluating data center intrusion-prevention systems (DCIPS), which face significantly higher traffic volumes than traditional IPSes.A typical IPS is deployed at the corporate network perimeter to protect end-user activity, while a DCIPS sits inline, inside the data center perimeter, to protect data-center servers and the applications that run on them. That requires a DCIPS to keep pace with traffic from potentially hundreds of thousands of users who are accessing large applications in a server farm, says NSS Labs, which recently tested five DCIPS products in the areas of security, performance and total cost of ownership.To read this article in full, please click here

AMD Gets Zen About The Edge

If there is one thing that can be said about modern distributed computing that has held true for three decades now, it is that the closer you get to the core of the datacenter, the beefier the compute tends to be. Conversely, as computing gets pushed to the edge, it gets lighter by the necessity of using little power and delivering just enough performance to accomplish whatever data crunching is necessary outside of the datacenter.

While we have focused on the compute in the traditional datacenter since founding The Next Platform three years ago, occasionally dabbling in the microserver arena …

Understanding IPv6: What Is Solicited-Node Multicast? (Part 4 of 7)

IPv6 solicited-node multicast somtimes seems to confuse those new to IPv6 in the beginning. I think this is because it seems so foreign and new. In this post, we will explore exactly what IPv6’s solicited-node multicast is and the rules of creating such an address as told to us by RFC 4291.

However, before we start on what’s new and different, let’s look at what solicited-node multicast has in common with IPv4 and IPv6 constructs that we already know.

In this blog post, we looked at IPv6 link-local scope multicast addresses. One of the examples was FF02::A. This address is for all devices on a wire that want to “talk” EIGRP with one another.

Focusing specifically on FF02::A and how routers join it, we can see and say three things:

  • Local: FF02::A is local to the wire.
  • Join: Each device “joins” FF02::A by just “deciding to listen” to the IPv6 link-local scope multicast address FF02::A. Then, by extension, it listens to the corresponding MAC address for that multicast IPv6 address (33:33:00:00:00:0A).
  • Common interest: As we can see, these varying groups have something in common that they would all like to hear about. For FF02::A, the common interest — the “connection” Continue reading

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 …
