Moving to Summer Schedule
The inevitable summer decline of visitors has started, so I'm switching (like every summer) to a lower publishing frequency. Given my current focus (here and here) expect one network automation post and one other in-depth post every week… and maybe an occasional this-is-worth-reading link.
Working in the summer office ;)
Take some time off, enjoy the vacations, and I hope to meet you in the September online course ;)

Cray CTO On The Cambrian Compute Explosion
What goes around comes around. After fighting so hard to drive volume economics in the HPC arena with relatively inexpensive X86 clusters in the past twenty years, those economies of scale are running out of gas. That is why we are seeing an explosion in the diversity of compute, not just on the processor, but in adjunct computing elements that make a processor look smarter than it really is.
The desire of system architects to try everything because it is fun has to be counterbalanced by a desire to make systems that can be manufactured at a price that is …

Knights Landing Can Stand Alone—But Often Won’t
It is a time of interesting architectural shifts in the world of supercomputing but one would be hard-pressed to prove that using the mid-year list of the top 500 HPC systems in the world. We are still very much in an X86 dominated world with the relatively stable number of accelerated systems to spice the numbers, but there are big changes afoot—as we described in depth when the rankings were released this morning.
This year, the list began to lose one of its designees in the list of “accelerator/offload” architectures as the Xeon Phi moves from offload model to host …

HPC Poised For Big Changes, Top To Bottom
There is a lot of change coming down the pike in the high performance computing arena, but it has not happened as yet and that is reflected in the current Top 500 rankings of supercomputers in the world. But the June 2017 list gives us a glimpse into the future, which we think will be as diverse and contentious from an architectural standpoint as in the past.
No one architecture is winning and taking all, and many different architectures are getting a piece of the budget action. This means HPC is a healthy and vibrant ecosystem and not, like enterprise …

Technology Short Take #84
Welcome to Technology Short Take #84! This episode is a bit late (sorry about that!), but I figured better late than never, right? OK, bring on the links!
Networking
- When I joined the NSX team in early 2013, a big topic at that time was overlay protocols (VXLAN, STT, etc.). Since then, that topic has mostly faded, though it still does come up from time to time. In particular, the move toward Geneve has prompted that discussion again, and Russell Bryant tackles the discussion in this post.
- Sjors Robroek describes his nested NSX-T lab that also includes some virtualized network equipment (virtualized Arista switches). Nice!
- Colin Lynch shares some details on his journey with VMware NSX (so far).
- I wouldn’t take this information as gospel, but here’s a breakdown of some of the IPv6 support available in VMware NSX.
Servers/Hardware
- Here’s an interesting article on the role that virtualization is playing in the network functions virtualization (NFV) space now that ARM hardware is growing increasingly powerful. This is a space that’s going to see some pretty major changes over the next few years, in my humble opinion.
Security
- Anthony Burke gives a little bit of a sneak peek Continue reading

Pivoting off Hidden Cobra Indicators
On June 13th 2017, US-CERT issued a joint Technical Alert (TA17-164A) entitled Hidden Cobra – North Korea’s DDoS Botnet Infrastructure. The alert, which was the result of analytic efforts between the Department of Homeland Security (DHS) and Federal Bureau of Investigation (FBI), included a list […]Some recommendations for the network engineers
In this post, I will share many network engineering blogs which will be very beneficial for the network engineering and for those who want to learn more about network design. Almost everyday I receive a message through social media or via email from the connections. What should we study ? I am new […]

What is MPLS Traffic Engineering and Why do you need MPLS-TE ?
MPLS Traffic Engineering is a mechanism that provides cost savings in an MPLS networks. How cost saving can be achieved ? How traffic is steered to the paths which wouldn’t be used in normal circumstances ? I will explain in this post. Let’s look at below topology. MPLS Traffic Engineering […]

Is HPE’s “Machine” the Novel Architecture to Fit Exascale Bill?
The exascale effort in the U.S. got a fresh injection with R&D funding set to course through six HPC vendors to develop scalable, reliable, and efficient architectures and components for new systems in the post-2020 timeframe.
However, this investment, coming rather late in the game for machines that need hit sustained exaflop performance in a 20-30 megawatt envelope in less than five years, raises a few questions about potential shifts in what the Department of Energy (DoE) is looking for in next-generation architectures. From changes in the exascale timeline and new focal points on “novel architectures” to solve exascale challenges, …

Serial Pinout for APC
This is just a quick note to remind me how to make serial cables for APC power strips. This cable works between an APC AP8941 and an Opengear terminal server with Cisco-friendly (-X2 in Opengear nomenclature) pinout.
Only pins 3,4 and 6 are populated on the 8P8C end. It probably doesn't matter whether the ground pin (black) lands on pin 4 or 5 because both should be ground on the Opengear end. The yellow wire is unused.
