Welcome to the New Age: ARIN Exhausts IPv4 Addresses
In the next few days, the American Registry for Internet Numbers (ARIN) will finally run out of IPv4 addresses. ARIN is the Regional Internet Registry (RIR) for the United States, Canada, the Caribbean, and North Atlantic islands, so any organization within those boundaries will no longer be able to guarantee assignment of new IPv4 addresses […]
Using Agile and Scrum Methodologies to Accelerate IPv6 Deployment
As I was reading Ed Horley’s fifth blog post in his series on IPv6 planning and deployment best practices, it made me think about how organizations shouldn’t wait to get started. Organizations should not delay their IPv6 deployment by trying to attempt to design it perfectly from the start. Large and small organizations tend to […]
Replacing Your WAN with IWAN
For many businesses today, employees are spread across multiple locations. Transferring data between these “branches,” the central data center, the Internet and cloud-based apps is complicated and expensive. But did you know there is a way to utilize the Internet to add horsepower to your branch network and to save money? Tapping in to the […]
Can SDN Switches Replace the Firewall?
One of my 2015 technology predictions was that more companies would start to deploy Software Defined Networking (SDN). Although the concept originated in the mid-1990s, SDN is finding an eager audience today as organizations seek a more dynamic, adaptable and cost-effective solution for their intensive data transfer requirements.
Security in the Data Center with Cisco ACI
I was recently selected to be a member of the Cisco Champions team in 2015. This is truly an honor and gives me the opportunity to share my thoughts on IPv6, data center security and networking on the Cisco Communities blog site.
How to Reduce Energy Use in the Data Center and Beyond
Did you know that IT is 25 – 55% of a company’s energy consumption, the largest unmanaged expense in the enterprise? IT “plug load” is a huge—and often overlooked—savings opportunity.
Simplify Data Management with Scale-out Storage
Why has storage become such a pressing issue for companies of all sizes in almost every industry? The answer lies in rising data loads, and it doesn’t take a data scientist to know that growing data goes hand-in-hand with data center expansion. Thankfully, new storage innovations have been rolled out to simplify the storage, management, […]
More Ways to Set Up Your Cloud Infrastructure for Failure
In my last post , I offered five steps for ensuring a disastrous deployment of hybrid cloud infrastructure. Below are a few more pieces of advice that you can take with a grain of salt (unless you’d like your deployment to fail).
How to Assure Failure in the Hybrid Cloud
One of the longest-lasting traditions in the computer industry is one of stubborn behavior in the face of change. Back in the days when mainframes ruled the earth and information technology (IT) was called management information systems (MIS), there were COBOL-encrusted contrarians who believed that personal computers (PCs) were a fad. They would never catch […]
Troubleshoot IPv6 and IPv4 with These Free Mobile Apps
Living “Life in a Dual Stack World” requires that we have tools available to help us operate both protocols with aplomb. After all, we will be performing many networking tasks twice; once for IPv4 and once for IPv6. Any technique or tool that we can utilize to speed up our configuration or troubleshooting will help […]
