I had a power outage recently that took out my entire lab in a very ungraceful manner – everything, well mostly everything, came back up without a hitch – but NSX was acting a bit weird, so I decided to redeploy the NSX Controllers. I removed all 3 controllers and tried redeploying but ended up […]
Customer, Partner, Vendor.
Over the last 9 months, a lot has happened in my life; I have a nice titanium plate in my shoulder now courtesy of a major car accident. I changed roles at Novosco from Infrastructure Engineer to Cloud Technologist – focusing more on R&D and emerging platforms, and I helped out Frank Denneman and Niels […]
vSphere 6.5 Host Resources Deep Dive
Over the last 6-9 months, I have been reviewing the vast majority of a new book just released to print by Frank Denneman and Niels Hagoort – The vSphere 6.5 Host Resources Deep Dive. This book is, without a doubt, the most in-depth look at host design I have ever read, we are not talking […]
Enabling IPv6 with DHCPv6-PD and PPPoE on a Fortigate
Out of morbid curiosity (and lack of IPv4 public address space available to me), I decided I wanted to enable IPv6 in my lab. However, before taking the plunge there, I would try it out on my residential ADSL line, I use the same brand of firewall there as in my lab so the experience […]
Vote for your top vBlogs and podcasts!
It’s time for the annual Top 100 vBlog voting as hosted every year by Eric Siebert. This year is notable as some of the long-standing champs of the blogging scene have chosen to withdraw (notably Frank Dennemann and Duncan Epping) to allow some new blood to enter the top 10. For good reason, as Duncan […]

Designing a networking platform for IaaS multi-tenancy
This post is part of the Multi-tenant IaaS Networking course.
Based on my last post, you’ll understand some of the challenges that are faced with traditional approaches to datacenter networking so let’s get into the high-level conceptual design here of how we might solve one of these problems. Most service providers have or are at least familiar with using MPLS for customer segregation in a […]
Multi-tenant network challenges
This post is part of the Multi-tenant IaaS Networking course.
As of late, I have been getting my feet wet in more networking things – Firstly out of necessity, but it has grown into a genuine area of interest to me. I have a homelab that I like to simulate a production working environment in, so I had a nice opportunity to lab up what […]
Interview on OpenTechCast!
Just a quick link referral today, I had the privilege to be interviewed by the great guys over at OpenTechCast during the UK VMUG in Birmingham a while back about the recent datacenter networking article, more in the pipeline as well as system architecture and design, also a nice little prod at the end about […]
Recovering NSX Manager with corrupt filesystem
I had a bit of a storage outage in my lab due to a funky behaviour on the Synology that I use as primary storage for all my VMs: Today I Learned: Adding IP address to interfaces on Synology causes reboots :/ Lab now in not such great shape. 80 VMs with APD. #vExpert — […]
