Dell Open Networking and SDN – All About Disaggregation
When Dell first announced its Open Networking initiative a little over a year ago, they were the first major networking vendor to do so. Very similar to what Dell did for servers, Dell is now doing for networking – allowing customers to choose their hardware and then choose what operating system they want to install. Continue reading

6WIND – From Data Plane Acceleration to Virtual Appliances
Data Plane Acceleration with 6WIND and Intel DPDK
6WIND is an interesting company I’ve been following for some time now, initially out of curiosity, and then out of more curiosity :-). They first started as a networking software company claiming to solve performance challenges for software defined networks (SDN) and network function virtualization (NFV). How you ask? They leverage the capabilities of multicore processors and Intel’s Data Plane Development Kit (DPDK) to allow direct access to the data plane enabling a zero-copy mode from network to CPU!

VMware NSX Service Composer: Advanced Security & Micro-segmentation
In a prior blog, Firewalling & Micro-segmentation with VMware NSX, I discussed some of the basics of firewalls and micro-segmentation with VMware NSX. In this blog, I’ll introduce how security groups via NSX Service Composer can be used with VMware NSX to further enhance the micro-segmentation and security capabilities. Continue reading

Security, Art of Hacking, & the Worst 2014 Security Breaches
Security is hot; no doubt about it. Consider the fact that between 2011 and 2013, venture investors put nearly $3 billion into cyber security companies, resulting in new funding for some 300 firms (Source: Thomson Reuters). Worldwide security software revenue alone totaled $19.9 billion in 2013, a 4.9 percent increase from 2012 revenue of $19.0 billion (Source: Gartner). According to Gartner, global cybersecurity spending is to reach $76.9 billion in 2015 and $80 billion in 2016; in 2011 it stood at $55 billion. Continue reading

Market Cannibalization, Innovation, and Consumer Demand
At MacWorld 2007, for the iPhone Keynote, Steve Jobs famously stated, “It’s the best iPod we’ve ever made.” In Q4 2006, iPod units sold stood at 8.73 million. In Q4 2014, iPods units sold were 2.64 million while iPhone and iPad units sold stood at 39.27 million and 12.32 million units respectively. (Source: Apple) Continue reading

Cumulus Linux on Dell Switches: Spine-Leaf Architecture & OSPF on Unnumbered Interfaces
In a prior blog, Cumulus Linux on Dell Networking Switches, I demonstrated how to install Cumulus Linux on a Dell S6000 switch and do some basic configuration. In this blog, I’ll demonstrate how to configure routing on Dell switches running Cumulus Linux. The example covered demonstrates a Spine-Leaf architecture with OSPF on unnumbered interfaces. In this example 2 x Dell S6000-ON and 2 x Dell S4810-ON switches [Cumulus Linux 2.1.1] are utilized. The lab setup is depicted by the network diagram below. Continue reading

Mac OS X: Java – “Application Blocked by Security Settings” Solution
Starting with Java 8 Update 20 (Java 8u20) and later versions the option to lower the security setting in the Java Console Panel to Medium has been removed. Prior, changing the setting to Medium would quickly resolve issues where certain unsigned Java applets would not run. Now, with Java 8u20 and later, only High and Very High levels are available. These security levels are described on the java.com website as stated below. Continue reading
