Data center cooling market set to explode in the coming years

The worldwide market for data center cooling equipment will reach $20 billion by 2024, a massive jump over the $8 billion spent in 2016. That is the finding of a report from Global Market Insights (GMI), which says cooling systems account for approximately 40 percent of the total energy consumption on average.Data center operators have been obsessed with lowering their PUE, or power usage effectiveness, the ratio of power consumed by the hardware to power consumed to cool it. The problem is that while Intel, AMD and the rest of the component vendors obsess over lowering thermals and overall heat generated, the density of these servers is increasing.To read this article in full, please click here

Check Point Firewall VM Disk Resize

How Does Internet Work - We know what is networking

It is related to Check Point MGMT VM with R80.10 in my story, but you would as well want to resize Check Point gateway firewall hardware box or VM. I was searching for a simple solution and found different ones that didn’t work for me, so here are the steps that you need to go through when you resize your CheckPoint VM disk in vCenter and then need to expand the partition inside Check Point VM in order to use the additional space. Of course, you did choose too small HDD for your VM when you created it and now

IDG Contributor Network: 5G and the need for speed

Tesla’s “Maximum Plaid” speed mode rockets its new Roadster from 0-60 in 1.9 seconds. If you think that’s fast, go ahead and Google “5G.”5G is Plaid for cellular networking – a next-generation mobile network that promises not only ten-times the available spectrum, for ten-times the download speeds, but across ten-times the devices and with a fraction of the latency.The move from 1Gbps to 10Gbps speeds will support bandwidth-intensive applications like high-definition video and virtual reality, and near real-time connections will enable ultra-low latency applications like autonomous cars, remote surgery and specialized applications within the Internet of Things (IoT).To read this article in full, please click here

Core Switching : Juniper EX8200 Vs Cisco 6800

Today I am going to talk about the Core switching where I am taking two vendors and compare the features between them. Here in the specific switch in the Core we can have two different models for which we are comparing the features. The two Switches are Juniper EX8200 and Cisco 6800 Core switches

Before I start with the models one by one,I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further. I will going to add many more videos soon on the channel, Please subscribe to the channel for the study network related videos

AWS re:Invent 2017 Keynote with Andy Jassy

This is a liveblog of the re:Invent 2017 keynote with Andy Jassy, taking place on Wednesday at the Venetian. As fully expected given the long queues and massive crowds, even arriving an hour early to the keynote isn’t soon enough; there’s already a huge crowd gathered to make it into the venue. Fortunately, I did make it in and scored a reasonable seat from which to write this liveblog.

The pre-keynote time is filled with catchy dance music arranged by a live DJ (same live DJ as last year, if I’m not mistaken). There’s already been quite a few announcements made this year even before today’s keynote: Amazon Sumerian (AR/VR service), new regions and availability zones (AZs), and new bare metal instances, just to name a few of the big ones. There’s been a great deal of speculation regarding what will be announced in today’s keynote, but there’s no doubt there will be a ton of announcements around service enhancements and new services. Rumors are flying about a managed Kubernetes offering; we shall see.

Promptly at 8am, the keynote starts with a brief video, and Andy Jassy, CEO of AWS, takes the stage. Jassy welcomes attendees to the sixth annual Continue reading

BGP as a Better IGP? When and Where?

A while ago I helped a large enterprise redesign their data center fabric. They did a wonderful job optimizing their infrastructure, so all they really needed were two switches in each location.

Some vendors couldn’t fathom that. One of them proposed to build a “future-proof” (and twice as expensive) leaf-and-spine fabric with two leaves and two spines. On top of that they proposed to use EBGP as the only routing protocol because draft-lapukhov-bgp-routing-large-dc – a clear case of missing the customer needs.

Celebrating 6 Years

How Does Internet Work - We know what is networking

Last month I celebrated 6 years of writing my blog. This project reached yesterday his most visited day in history with more than 1500 visitors and more than 31K all together in November. Nice to finally see someone actually reading my rumblings. It was and still is hard work of editing old posts making them better and finding new interesting stuff to write about. Blog is about computer network technologies, you know, the stuff that makes thing get to you and appear on your device’s screens so you can stare at it all the time ? Some other interesting trivia:

The Ecosystem Expands For AMD Epyc Servers

The “Naples” Epyc server processors do not exactly present a new architecture from a new processor maker, but given the difficulties that AMD had at the tail end of the Opteron line a decade ago and its long dormancy in the server space, it is almost like AMD had to start back at the beginning to gain the trust of potential server buyers.

Luckily for AMD, and its Arm server competitors Qualcomm and Cavium, there is intense pressure from all aspects of high-end computing – internal applications and external ones at hyperscalers and some cloud builders as well as enterprises …

IDG Contributor Network: How to help your files speak S3

Among the many clouds in the storage sky, Amazon Web Services is the dominant leader by far. The annual AWS re:Invent trade show is taking place in Las Vegas this week, and given how many enterprises have some data in the AWS cloud, the event is expected to sell out.It’s no secret that the cloud is one of today’s top storage industry disruptors, significantly reshaping enterprise IT architectures and investments. Cloud object storage has a well-earned reputation for cutting costs since enterprises can avoid both upfront capital and costly operational expenditures by storing data off-premises. However, the challenges of getting data to the cloud means many enterprises are only getting started on adoption. There is much more growth ahead, as the cloud’s elastic scaling can also deliver agility, but so far, most enterprises are relegating cloud storage for archival.To read this article in full, please click here

Worth Reading: Quad9

In a joint project, IBM Security along with Packet Clearing House (PCH) and The Global Cyber Alliance (GCA) today launched a free service designed to give consumers and businesses added online privacy and security protection. The new DNS service is called Quad9 in reference to the IP address 9.9.9.9 offered for the service. The group says the service is aimed at protecting users from accessing malicious websites known to steal personal information, infect users with ransomware and malware, or conduct fraudulent activity. —CircleID In a joint project, IBM Security along with Packet Clearing House (PCH) and The Global Cyber Alliance (GCA) today launched a free service designed to give consumers and businesses added online privacy and security protection.

NetDevOpEd: The right tool for the right job

I’ve been traveling to northern Europe these past few months to meet with various customers, deliver onsite trainings and speak at meetups. I’ve noticed some common themes that crop up no matter with whom I speak. IT professionals are exhausted by the complexity required to manage and maintain their infrastructure. Somehow, networking and server interconnectivity has become this unmanageable complex mess over the past 20 years. And I don’t blame them. As networking has layered on more and more solutions, it becomes hard to separate out the complexity from the deployment.

Normally when I have these conversations, I start at the most basic levels. I focus on two topics that create the most grief for the vast majority of networks:

Layer 1 cabling issues
Typos and misconfigurations

The reason I start there is because resolving these two issues in the data center would eradicate over 90% of all issues that cause late maintenance windows and urgent midnight troubleshooting calls.

At Cumulus Networks, we resolve these issues by rethinking what it means to configure a network device. The most effective solution to both of these issues is simplification of configuration. Because we focus on integration and solution first, we are able Continue reading

Terminology Tuesday Presents: Blockchain

Think of Blockchain as primarily two things. 1) A peer-to-peer technology 2) A way of keeping a public record.

The technological backing of Blockchain is the ability to have many (many) computers host the same information. Snippets of code (known as blocks) are duplicated and maintained in so many different places rendering fraud impossible. The fact that each of these blocks is timestamped and unique makes it increasingly challenging to outsmart. If you’re interested in learning more about the technological specifics there are a number of great resources online including this presentation by Binh Nguyen, IBM’s Blockchain Fabric Chief Architect.

Today, Blockchain is most commonly thought of in connection to Bitcoin as it describes the technology and process that we’ve all come to know as being so secure. Bitcoin’s past affiliations with illegalities of all sorts have given a bad name to Blockchain but there are many benefits to secure transactions all with a public record as our purchases and currency become increasingly digital.
