Introduction This article is the second in a series addressing questions around how much latency the various functions of NSX add when compared to a purely physical network design. The last article focused on the NSX Distributed Firewall. This time, we’ll be looking at VTEPs/VXLANs and Distributed Logical Routers from an East/West traffic perspective. We […]
A lot of people want to submit and defend for their VCDX, but they never get around to putting their design together because they just don’t know where to begin – especially people who are starting from scratch with a wholly fictitious design. I suffered from this myself, and wrung my hands for a long […]
I’m on the plane back from another set of VCDX panels, and I’m reminded of an area of Enterprise Architecture that seems to be glossed over: Risk Management. I read through a lot of design submissions that are light in this area. This is concerning to me because any Enterprise Architecture methodology worth its salt […]
Introduction A lot of the customers I talk to who are considering virtualizing their network ask what the “overhead” or “performance penalty” is for running NSX. The general answer is “so low that you probably won’t be able to measure it”. For some people, that’s not enough. They want to know an exact figure for, […]
I help a lot of customers across verticals and segments spitball how they are going to lay out their rules when they implement NSX Distributed Firewall. For some reason, many of them don’t seem to appreciate how much simpler Service Composer can make the management of these rules via nested Security Policies vs. just doing […]
This is an excerpt from a presentation I give to explain the value of VMware Professional Services and why a customer needs the services of an Enterprise Architect. It uses cars as an analogy for people who aren’t very familiar with vSphere, because most technical people I’ve met have some frame of reference when it […]
The simplest way to explain the purpose of EA is to paraphrase John Zachman: “We should try to understand the Enterprise first, before we go and build infrastructure to support it. Infrastructure is expensive, and takes time to implement or migrate to, but most importantly it is hard to change once in production. Therefore the […]
Why am I writing this? Why would anyone run vSphere on Intel Atom? There are a number of use cases that spring to mind (DAAS, ROBO, Dev/Test, Labs, etc), but let’s focus on one that recently cropped up in my daily routine. I have been working with a couple of large service provider customers who […]
I thought I’d share some observations about testing my first real-deal-non-simulated, non-nested, non-HOL, non-bogus production VSAN 2.1 cluster on vSphere 6 U1. This stuff may be old news for a VSAN specialist, but I’ve been heavily focused on NSX this year and frankly haven’t had a chance until now to really implement VSAN in production […]
I just received word that my VCDX-NV design package passed scrutiny, and I am now officially a double VCDX (I already obtained my VCDX-DCV about 18 months prior). I have zero inclination at the moment to try for a third. Way too many other side projects that need attention. This blog, for example. But who […]
