I had a question last week from Bozo Popovic during our EMEA field SE training session on vSAN operations relating to SPBM support for service providers that use vCloud Director in their environments. Next up Mr. @mylesagray giving a #vSAN operations overview to our EMEA field at the @vmwarevsan workshop this morning pic.twitter.com/48seQc8i7d— Cormac Hogan […]
Migrating vSAN vmkernel ports to a new subnet
After deploying a vSAN cluster, the need sometimes arises to make changes to its network configuration, such as migrating the vmkernel network of the cluster to a new subnet. This requirement may appear for example when changing the network in which the vSAN cluster is running, or even, in a more complex scenario such as […]
vCloud Director console proxy and UI on a single interface
I was recently rebuilding part of my lab infrastructure, and as part of it, I wanted to migrate my vCD cells from two IPs each to a single IP (as this feature was added in vCD 8.10) for both the web UI and the console proxy. It simplifies provisioning, potential routing problems, and load-balancer configuration […]
Removing orphaned IPs from NSX using REST API
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 […]
Implementing a multi-tenant networking platform with NSX
This post is part of the Multi-tenant IaaS Networking course.
So we have covered the typical challenges of a multi-tenant network and designed a solution to one of these, it’s time to get down to the bones of it and do some configuration! Let’s implement it in the lab, I have set up an NSX ESG Cust_1-ESG and an NSX DLR control VM Cust_1-DLR with […]
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 […]
