Brocade Gen6 Fibre Channel prepares businesses for an all-flash world

Last year, Brocade introduced its 32 Gig Fibre Channel portfolio. Gen6, as Brocade calls it, is ideally suited to meet the demands of a digital world that is seeing an explosion of traffic from data center modernization, the Internet of Things (IoT) and cloud computing.Earlier this week the company announced its new G610 switch. The product is designed to be an entry-level switch that enables businesses to start at eight ports and then expand to 24 ports through a software license. The ports can be configured to run at 16 Gbps today and then upgraded to 32 Gbps when the data demands require it. To read this article in full or to leave a comment, please click here

Google Calendar finally comes to the iPad

Google’s Calendar app is making a long-awaited move to a new device: Apple’s iPad. You read that right: Until Wednesday, the tech titan hadn’t optimized its marquee calendar application to run on Apple’s tablets.The app provides users with a view of the calendars that they have and that are shared with them through Google’s service. In addition, they get a handful of features Apple’s native calendar app doesn’t have, like the ability to more easily find time and space for a meeting with other people inside their organizations.Making iPad users wait for a native Calendar app is hardly a surprise coming from Google, considering that it’s the company behind Android, and frequently ships new features first to apps for devices running its mobile operating system.To read this article in full or to leave a comment, please click here

Cord cutting is happening. No it’s not. Yes it is. No it’s not…

I practically kick myself every time our Verizon FiOS cable bill arrives because I still haven't acted on my intention to cut the cord in some way that won't drive my family nuts and will allow me to watch local sports.Re-energizing my focus of late, I've created a Google Alert on "cord cutting" to force myself to read up on the topic and latest statistics daily. But if I was confused before, I'm even more so now.MORE: Father of the web cites 3 big concerns about his 28-year-old babyDeloitte, in its 11th annual Digital Democracy Survey of U.S. consumers, found that three quarters of more than 2,100 consumers surveyed online said they still subscribe to pay TV, such as cable or satellite, most because it comes bundled with internet service.

And more services, like YouTube TV announced last month, keep coming.To read this article in full or to leave a comment, please click here

Ever wonder how many books you’ll have read by the time you die? We may never know the answer to that question, but we might be able to guess how many we have remaining. A recent article in Quartz highlights just that in two fascinating graphs. Based on the number of books the average American reads every year (12), the charts show estimates of the number of books men and women can expect to have left in their reading careers. —Intellectual Takeout

IDG Contributor Network: The gender gap: How to build a pipeline of women IT leaders

Compared to other corporate functions, women are significantly underrepresented in IT leadership positions. According to CEB data, women currently represent 38 percent of all functional leaders in North America. However, they represent just 28 percent of IT leaders.The potential for negative public scrutiny is a primary concern stemming from this gender gap, but there is another often hidden concern: An IT gender gap can create challenges in effectively delivering on customer services. As IT shifts from serving as builders of internal IT products towards builders of customer-facing digital service experiences, it’s critical to have IT leaders reflect the customer base that they serve.To read this article in full or to leave a comment, please click here

Donald Trump using a new iPhone after calling for Apple boycott

About a year ago, Donald Trump publicly called for a boycott of Apple products following Apple's refusal to help the FBI access data from an iPhone 5c that belonged to one of the San Bernardino terrorists. To be fair, Apple was willing to help, but was unwilling to create a custom version of iOS that would have allowed the FBI to circumvent some of iOS' built-in security features.Apple's refusal to cower to the FBI bothered Trump to such an extent that he even referenced it during a stop on his campaign tour last year."First of all, Apple ought to give the security for that phone," Trump said. "What I think you ought to do is boycott Apple until such time as they give that security number."To read this article in full or to leave a comment, please click here

As April brings the best college basketball teams together for the final leg of March Madness, college basketball is in full swing. With all this attention on the top teams and programs in country, there is more than one parallel between data center managers and NCAA basketball coaches.Their management techniques and job descriptions often align: optimizing lineups to ensure they have the best team on the floor in the final seconds of a big game, or stressing teamwork and cooperation during tight deadlines, outages or other time-sensitive situations. Coaches and data center managers play a similar role to ensure their team (or infrastructure) is ready to perform when it matters most.To read this article in full or to leave a comment, please click here

Trojan source code leak poised to spur new online banking attacks

The source code for a new Trojan program that targets banking services has been published online, offering an easy way for unskilled cybercriminals to launch potent malware attacks against users.The Trojan is called Nuclear Bot and first appeared for sale on underground cybercrime forums in early December for $2,500. It can steal and inject information from and into websites opened in Mozilla Firefox, Internet Explorer and Google Chrome and can also open a local proxy or hidden remote desktop service.These are all features commonly seen in banking Trojans, as they're used by attackers to bypass the security checks of online bank websites to perform fraud. For example, the proxy and remote desktop functionality allows hackers to initiate rogue transactions through the victims' browsers after they have been tricked into providing the second authentication factor.To read this article in full or to leave a comment, please click here

Kubernetes networking 101 – Pods

Some time ago I wrote a post entitled ‘Kubernetes networking 101‘.  Looking at the published date I see that I wrote that more than 2 years ago!  That being said – I think it deserves a refresher.  The time around, Im going to split the topic into smaller posts in the hopes that I can more easily maintain them as things change.  In today’s post we’re going to cover how networking works for Kubernetes pods.  So let’s dive right in!

In my last post – I described a means in which you can quickly deploy a small Kubernetes cluster using Ansible.  I’ll be using that environment for all of the examples shown in these posts.  To refresh our memory – let’s take another quick look at the topology…

The lab consists of 5 hosts with ubuntu-1 acting as the Kubernetes master and the remaining nodes acting as Kubernetes minions (often called nodes now but I cant break the habit).  At the end of our last post we had what looked like a working Kubernetes cluster and had deployed our first service and pods to it.  Prior to deploying to the cluster we had to add some routing in the form Continue reading

Microsoft’s Surface Book and Surface Studio will ship in more markets

Microsoft has been cautious about making its Surface product line available worldwide. It tests devices in specific markets, sees how they do, and if the response is good, ships them to those areas.The company appears to have have received a strong response, in particular, to its Surface Studio, Surface Book devices and Surface Dial, which will soon be available in many Asian and European countries.The expanded availability of these devices was announced on the same day Microsoft said it would release Windows 10 Creators Update on April 11.The Surface Book with Performance Base, one of the devices that will be more broadly available, is a high-performance laptop that can also be a tablet. The screen pops out from the keyboard base to be a tablet. In a review, PC World concluded the device was powerful and easy to use, but had some design issues and was heavy.To read this article in full or to leave a comment, please click here
