While I have stock homework assignments prepared for every module of the Building Network Automation Solutions online course I always encourage the students to pick a challenge from their production network and solve it during the course.
Pavel Rovnov decided to focus on consistency of network management parameters (NTP, SNMP, SSH and syslog configuration) across Extreme and Cumulus switches, Fortinet firewalls and several distributions of Linux.
Read more ...If Mellanox Technologies had not begun investing in the Ethernet switching as it came out of the Great Recession, it would be a much different company than it is today. It might have even been long since acquired by Oracle or some other company, for instance.
To be sure, Mellanox might have been able to capture some business at the cloud builders, hyperscalers, and clustered storage makers with InfiniBand. But it would not have been the one to capitalize on moving InfiniBand-style technologies such as remote direct memory access (RDMA) to Ethernet, and it would not have been able to …

Many of my students have been asking whether CCDE Practical/Lab Exam Result policy is still the same. As you might know after CCDE 2017 May exam cancellation , practical exam results can be learned after 8 to 12 weeks. This mean, if you attend CCDE Practical exam, you cannot learn the result (Pass or fail) …

If it were not for the insatiable bandwidth needs of the twenty major hyperscalers and cloud builders, it is safe to say that the innovation necessary to get Ethernet switching and routing up to 200 Gb/sec or 400 Gb/sec might not have been done at the fast pace that the industry as been able to pull off.
Knowing that there are 100 million ports of switching up for grabs among these companies from 2017 through 2021 – worth tens of billions of dollars per year in revenues – is a strong motivator to get clever.
And that is precisely what …

Designing and manufacturing processors – or paying a third party foundry to do some of the work – and then manufacturing systems and updating and modernizing operating systems and middleware is tough work. And it is work that few IT vendors and about the same number of hyperscalers do these days. Despite all of the gut-wrenching changes in the datacenter over the past six decades, International Business Machines is still in the game that it largely defined so long ago.
In the fourth quarter of 2017, the company’s System z mainframes had the highest shipment level, as gauged by aggregate …

For those who may not have heard, Cisco recently updated their blueprint for the CCIE Service Provider Written and Lab Exams. According to Cisco, only about 10% of the overall blueprint has changed and topics on 4.1 will be similar to those on 4.0. Read on to learn more.
Domain Changes:
4.1 domain topics are almost exactly the same as 4.0 topics. The main difference in domains is that domains 1 and 3 (service provider architecture and evolution and service provider base services) have been merged into one domain. While other domain topics did not change, slight shifts were made to domain weights.
Weighting of Domains:
Topic changes within the Domains:
