Intel launches Optane, the go-between for memory and storage

Intel formally introduced the Optane DC persistent memory modules late last week, an entirely new class of memory and storage technology designed to sit between storage and memory and provide expanded memory capacity and faster access to data.Unlike SSDs, which plug into a PCI Express slot, Optane DC is built like a thick memory DIMM and plugs into the DIMM slots. Many server motherboards offer as many as eight DIMM slots per CPU, so some can be allocated to Optane and some to traditional memory.That’s important because Optane serves as a cache of sorts, storing frequently accessed data in its memory rather than forcing the server to fetch it from a hard disk. So, server memory only has to access Optane memory, which is sitting right next to it, and not a storage array over Fibre Channel.To read this article in full, please click here

IDG Contributor Network: The 6 ways to make money in IoT

According to the McKinsey Global Institute, IoT will have a total potential impact of up to $11.1 trillion a year by 2025. With so much opportunity, it makes sense why so many companies are looking to connect their devices and enter the IoT arena.But simply adding an internet connection to your widget doesn’t mean your business will make immediate profits. IoT products come with significant ongoing costs – web infrastructure, networking, and other connectivity and data-related costs. If you can’t justify the additional value to your customers, those costs will eat away at your margins.To read this article in full, please click here

IPv6 Adoption Still Lags In Federal Agencies


On September 28, 2010, Vivek Kundra, Federal CIO at the time, issued a “Transition to IPv6” memorandum noting that “The Federal government is committed to the operational deployment and use of Internet Protocol version 6 (IPv6).” The memo described specific steps for agencies to take to “expedite the operational deployment and use of IPv6”, and laid out target deadlines for key milestones. Of specific note, it noted that agencies shall “Upgrade public/external facing servers and services (e.g. web, email, DNS, ISP services, etc) to operationally use native IPv6 by the end of FY 2012.”

For this sixth “launchiversary” of the World IPv6 Launch event, we used historical Internet Intelligence data collected from Oracle Dyn’s Internet Guide recursive DNS service to examine IPv6 adoption trends across federal agencies both ahead of the end of FY 2012 (September 2012) deadline, as well as after it.

Background

The data set used for this analysis is similar to the one used for the recent “Tracking CDN Usage Through Historical DNS Data” blog post, but in this case, it only includes .gov hostnames. While the memorandum calls out the use of IPv6 for ‘web, email, DNS, ISP services, etc.’, in order Continue reading

Datanauts 137: Automating Infrastructure As Code With Terraform

The robotic production facilities on board the Datanauts’ dreadnought cruiser are really great at making scout drones for identifying rich mineral deposits. Sadly, our probe production numbers are fairly low right now, because every single build is done by hand.

Blasphemy! We need a way to simply define the end state of our drone creation and then let an orchestration engine handle all of the building. Plus, if the design changes, we need to make sure all of the existing drones are retrofitted to take advantage of the new improvements! What can be done?!

Our guest today is Ned Bellavance. We pick Ned’s brain about infrastructure as code and his hands-on experience with HashiCorp’s Terraform.

Video – Vint Cerf on the 6th anniversary of World IPv6 Launch and why IPv6 is so critical now

Today, on the sixth anniversary of World IPv6 Launch, Vint Cerf, co-designer of the TCP/IP protocol and a “Father of the Internet”, sent us this video message to share with you all:

To learn more about IPv6, read our State of IPv6 Deployment 2018. And if you have not yet started, visit our Deploy360 IPv6 resources to learn how you can begin.

Six Years After: State of IPv6 Deployment 2018

On the sixth anniversary of World IPv6 Launch, we’re sharing an updated report on the State of IPv6 Deployment in 2018. It really is staggering how far IPv6 deployment has progressed in six years. In mid-2012, Google measured less than 1% of users accessing their services over IPv6. Today that figure is getting close to 25%. Several major operators now deliver the majority of traffic from major content sources like Google, Akamai and Facebook over IPv6. Individual operators, like T-Mobile USA, have deployed IPv6-only networks for their subscribers.

Seven years ago, the Internet Society helped to organize World IPv6 Day, where thousands of ISPs and websites joined together for a successful, global-scale, 24-hour trial of IPv6. A year later, for World IPv6 Launch, major ISPs, home networking equipment manufacturers, and web companies around the world permanently enabled IPv6 for their products and services.

To help showcase the progress made in the six years since World IPv6 Launch we are sharing:

– an updated report on the State of IPv6 Deployment 2018
– an infographic that clearly shows the scale and scope of IPv6 deployment
– and a fun quiz for you to test and share your knowledge of the Continue reading

IBM strengthens mainframe cloud services with CA’s help

You’re probably doing your IIoT implementation wrong

The Industrial internet of things promises a quantum leap forward in automation, centralized management and a wealth of new data and insight that is often too tempting to pass up. But automating a factory floor or a fleet of vehicles is far from simple, and many would-be IIoT adopters are going about the process all wrong, according to experts.To make an IIoT transition a success, the process has to be led by the line-of-business side of the company – not IT. Successful IIoT adopters frame the entire operation as a matter of digital transformation, aimed at addressing specific business problems, rather than as a fun challenge for IT architects to solve.To read this article in full, please click here

6 years on, IPv4 still dominates IPv6

IPv6, the modern version of the Internet Protocol framework that underlies just about everything on the network, is seeing steady uptake among service providers, but still hasn’t pushed its predecessor, IPv4, into obsolescence, according to a report released today by the Internet Society.There are 24 countries in the world where IPv6 totals more than 15% of overall IP traffic, and 49 that have topped the 5% threshold. Yet the Internet Society – a non-profit that works to promulgate internet standards and lobby for open access to the internet – describes the technology as having moved from the “early adoption” development stage to the “early majority” phase.To read this article in full, please click here

Automation Win: Document Cisco ACI Configuration

This blog post was initially sent to the subscribers of my SDN and Network Automation mailing list. Subscribe here.

A while ago I complained how the GUI- or API-based orchestration (or intent-based) systems make it hard to figure out what exactly has been configured because they can’t give you a single text configuration file that you could track with version-control software.

Dirk Feldhaus found the situation so ridiculous that he decided to create an Ansible playbook that collects and dumps tenant parameters configured on a Cisco ACI tenant as a homework assignment in the Building Network Automation Solutions online course. As he explained the problem:

Reducing DRAM footprint with NVM in Facebook

Reducing DRAM footprint with NVM in Facebook Eisenman et al., EuroSys’18

(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site).

…to the best of our knowledge, this is the first study on the usage of NVM devices in a commercial data center environment.

We’ve been watching NVM coming for some time now, so it’s exciting to see a paper describing its adoption within Facebook. MyRocks is Facebook’s primary MySQL database, and is used to store petabytes of data and to serve real-time user activities. MyRocks uses RocksDB as the storage engine, and a typical server consumes 128GB of DRAM and 3 TB of flash. It all seems to work well, so what’s the problem? Spiralling costs!

As DRAM facing major scaling challenges, its bit supply growth rate has experienced a historic low. Together with the growing demand for DRAM, these trends have led to problems in global supply, increasing total cost of ownership (TCO) for data center providers. Over the last year, for example, the average DRAM DDR4 price has increased by 2.3x.

Just using less DRAM per server Continue reading
