After spending a bit of time tidying up cables in my rack, I figured I’d take the opportunity to write about my current setup. Here it is in all its glory: Not the greatest picture. From top to bottom: Here’s a diagram of how it’s all connected together. Not in the diagram is a UniFi … Read more
I previously blogged about how you can get BGP working between a UDM-SE and NSX Edge. I wanted to revisit the topic as BGP is now built into the UDM itself as of GW firmware 4.1 I believe, and there is no requirement to visit the command line except to troubleshoot and verify. I also … Read more
Whilst HCX is a perfectly suitable to migrate most workloads, there are some which require careful consideration and planning such as SQL Clusters, Oracle (or other database servers), load balancers, and even Active Directory Domain Controllers. Domain Controllers definitely fall into the category of requiring extra consideration before migrating them with HCX. Whilst it is … Read more
HC 4.10 has just been released and with it come a whole host of excellent new features. You can read the release notes here: https://docs.vmware.com/en/VMware-HCX/4.10/rn/vmware-hcx-410-release-notes/index.html In this post, I want to concentrate on what will be welcome to customers who operate their own private datacentres and have no use for encryption. Historically, the traffic between … Read more
With the release of HCX 4.8 comes in my opinion one of the biggest new features released since Network Extension High Availability went IA in 4.3. In previous versions for any given Compute Profile pair, while it was possible to deploy more than one Service Mesh, only the first one would be used. I previously … Read more
I’ve seen a few cases in the field where a HCX Manager has been deployed onto the same network which is use by workload VMs, and to make matters worse, the network is in scope for being stretched and then moved to the target environment. The issue here is that when you come to unstretch … Read more
I previously blogged that you can install and enable FRR on a UniFi UDM (or UDM SE) running UniFi OS 3.0.x. which gives you the ability to run BGP; in my case I was using it to talk to my NSX Tier-0 Edge. I noticed I started getting some weird issues after the first 3.1.x … Read more
HCX OS Assisted Migration (OSAM for short) is a VMware tool where VMs hosted on either KVM or Hyper-V or can be migrated into vSphere. It’s designed to work at scale and can do 50 concurrent migrations per Service Mesh and will scale up to four Service Meshes; allowing up to 200 total parallel migrations. … Read more
LACP on ESXi is fairly common with some vendors that do their own networking between the Top of Rack switches and the hosts, such as Cisco UCS and HPE Synergy. This has been problematic as extending networks with this configuration has typically been unsupported. Up until recently, the HCX documentation has called out the following … Read more
Although I have previously documented my homelab, there have been some changes as well as a housemove. This is part 1 of my 2023 update. This is how it was around a week ago, and as you can see it’s a bit of a mess. The Lack ‘Rack’ was only tempoary and I’ve had it … Read more
