Data center power efficiency increases, but so do power outages

A survey from the Uptime Institute found that while data centers are getting better at managing power than ever before, the rate of failures has also increased — and there is a causal relationship.The Global Data Center Survey report from Uptime Institute gathered responses from nearly 900 data center operators and IT practitioners, both from major data center providers and from private, company-owned data centers.It found that the power usage effectiveness (PUE) of data centers has hit an all-time low of 1.58. By way of contrast, the average PUE in 2007 was 2.5, then dropped to 1.98 in 2011, and to 1.65 in the 2013 survey.To read this article in full, please click here

Are microservices about to revolutionize the Internet of Things?

Along with the rise of cloud computing, Agile, and DevOps, the increasing use of microservices has profoundly affected how enterprises develop software. Now, at least one Silicon Valley startup hopes the combination of microservices and edge computing is going to drive a similar re-think of the Internet of Things (IoT) and create a whole new software ecosystem.Frankly, that seems like a stretch to me, but you can’t argue with the importance of microservices to modern software development. To learn more, I traded emails with Said Ouissal, founder and CEO of ZEDEDA, which is all about “deploying and running real-time edge apps at hyperscale” using IoT devices.To read this article in full, please click here

What is data deduplication, and how is it implemented?

Deduplication is arguably the biggest advancement in backup technology in the last two decades.  It is single-handedly responsible for enabling the shift from tape to disk for the bulk of backup data, and its popularity only increases with each passing day.  Understanding the different kinds of deduplication, also known as dedupe, is important for any person looking at backup technology.What is data deduplication? Dedupe is the identification and elimination of duplicate blocks within a dataset. It is similar to compression, which only identifies redundant blocks in a single file. Deduplication can find redundant blocks of data between files from different directories, different data types, even different servers in different locations.To read this article in full, please click here

50 Shades of Open Source: How to Determine What’s Suitable for Enterprise White Box Networking

To date, the open source community has been quite successful in terms of coming up with scalable and reliable implementations for enterprise servers, databases and more. Yet many enterprises remain skittish about implementing open source software, probably no more so than in the networking space.

Part of the reason is that there are so many different implementations of open source software, many of them backed by different entities with different agendas. Having many minds contribute to an open source project can be a good thing – until it comes time to make a decision about something and stick with it, so you can get a working product out the door. Enterprises need practical implementations that they can count on day in and day out to get a job done.

Defining the shades of open source
Open source essentially comes in different shades that are not all created equal. Understanding them will help you determine whether the open source implementation you have in mind has the kind of reliability and stability you need in any enterprise IT tool or application.

At a base level is the “pure” open source community, where like-minded people contribute their time and knowledge to a project. Continue reading

What is DHCP, and why might its days may be numbered as IPv6 grows?

Dynamic Host Configuration Protocol (DHCP) is the standard way network administrators assign IP addresses in IPv4 networks, but eventually organizations will have to pick between two protocols created specifically for IPv6 as the use of this newer IP protocol grows.DHCP, which dates back to 1993, is an automated way to assign IPv4 addresses, but when IPv6 was designed, it was provided with an auto-configuration feature dubbed SLAAC that could eventually make DHCP irrelevant. To complicate matters, a new DHCP – DHCPv6 – that performs the same function as SLAAC was independently created for IPv6. [ Now read 20 hot jobs ambitious IT pros should shoot for. ] Deciding between SLAAC and DHCPv6 isn’t something admins will have to do anytime soon, since the uptake of IPv6 has been slow, but it is on the horizon.To read this article in full, please click here

Intel continues to optimize its products around AI

Normally, this is the time of year when Intel would hold its Intel Developer Forum conference, which would be replete with new product announcements. But with the demise of the show last year, the company instead held an all-day event that it live-streamed over the web.The company’s Data Centric Innovation Summit was the backdrop for a series of processor and memory announcements aimed at the data center and artificial intelligence, in particular. Even though Intel is without a leader, it still has considerable momentum. Navin Shenoy, executive vice president and general manager of the Data Center Group, did the heavy lifting.News about Cascade Lake, the rebranded Xeon server chip First is news around the Xeon Scalable processor, the rebranded Xeon server chip. The next-generation chip, codenamed “Cascade Lake,” will feature a memory controller for Intel’s new Intel Optane DC persistent memory and an embedded AI accelerator that the company claims will speed up deep learning inference workloads by eleven-fold compared with current-generation Intel Xeon Scalable processors.To read this article in full, please click here

Improving Gender Rights Online: Perspectives from the Global South

The Internet has helped to empower communities of across the globe. However, existing gender disparities, discrimination, and inequalities, especially faced by women living in the Global South, including the least developed countries, has had a  considerable impact on the digital gender divide, leading to the digital exclusion of women.

A study “Views & Perspectives on Gender Rights Online, for the Global South”, was undertaken by Amrita Choudhury, CCAOI & Asia Pacific lead for the Internet’s Society SIG Women and Nadira AL Araj, ISOC Palestine and MENA Civil Society activist, to identify the main challenges towards improving the gender access and rights online, especially in the Global South; highlight the best practices which nations or regions have adopted to overcome those challenges; and suggest policy areas which need reforms.

In addition to relying on secondary sources, the opinions of 19 experts from 15 countries and responses of 162 people from 54 countries were sought. The findings were further discussed and validated through a workshop at the Internet Governance Forum (IGF) 2017 “Redefining Rights for a Gender Inclusive Connected Future (WS 102) and then compiled into a report.

The top challenges identified across the Global South hampering the creation Continue reading
