Jenkins as system job scheduler

Jenkins is an open software tool, typically used for continuous integration in software development. Network or system changes can be treated in a similar way as code changes are: developed, tested and deployed. Test frameworks are coming  to Network world (look at TODD) but are not popular yet.  Even without unit tests we can still use developer tools like Jenkins […]

Leveraging IXP Colocation as an Enterprise

Providing a comprehensive solution for global connectivity is still not a trivial task. As most global enterprises know, the scale both geographically and organizationally can kill almost any well engineered network design.  Size and complexity aside, just designing for the next “XaaS” solution and cloud sprawl can greatly challenge most network engineers One approach to […]

Back to Basics: Cooling – Part 1

In this pair of articles I will be dissecting the fundamentals of cooling and refrigeration from an IT engineering perspective, then going over the process of sizing a cooling system. As infrastructure engineers, we likely deal with the topic of cooling on occasion, and those occasions tend to be during a facility buildout/upgrade or outage […]

Breaking down the Ivory Tower part 1 – Vision

Network engineers and operators may often feel themselves at odds with network architects, who live in ivory towers and make pronouncements from on high about how a network should be set up, but aren’t actually responsible for making it work. Now for those that have listened to the Datanauts show on VCDX certification (at around […]

Power9, GPUs, FPGAs will have a profound effect on the data center

Last week brought us, in my opinion some of the biggest news that I’ve read recently. In a nutshell the news was that Google is working with Rackspace and IBM and that they have created an OpenPower Foundation. In a nutshell, they’re collaborating on open hardware designs based on the Power9 architecture from IBM and, at […]

cPacket Provides Distributed, Line-Rate, Real-Time Packet Analysis

The core cPacket value proposition is that of deep packet inspection and analysis at line rate in a scalable, distributed manner. Rather than merely directing traffic to various tools for analysis by creating a visibility fabric, cPacket handles both the functions of visibility fabrics as well as traffic analysis tools.

Savvius Insight Review

Recently, I had the opportunity to evaluate a Savvius Insight appliance. Like most freelance network professionals, much of my interaction with my clients’ networks is remote. This leaves me with fewer options for network analysis and troubleshooting, so I jumped at the chance to look at something that might fill that gap. The Hardware The appliance […]
