Quick answer: distributed switch versus port group A vSphere Distributed Switch (vDS) is the datacenter-level switch configuration that vCenter Server applies consistently across multiple ESXi hosts. A distributed port group is a policy-defined set of ports on that switch for a specific network or traffic type. Create the vDS first, create and validate its port … Explore: Create a vSphere Distributed Switch and Port Groups
VMware has just released a new document to perform a migration from NSX-V to NSX-T leveraging the NSX-T Datacenter Migration Coordinator. Click to access nsxt_24_migrate.pdf Happy reading.
Prerequisites The VMs must be hosted on hypervisors that have been added to the NSX-T Data Center fabric. The fabric nodes must have NSX-T Data Center management plane (MPA) and NSX-T Data Center control plane (LCP) connectivity. The fabric nodes must be added to a transport zone. A logical switch must be created. Steps: In … Explore: Connecting a Virtual Machine to a NSX-T Logical…
When I first tackled NSX-T, like many, I was concerned about IO/Packet flow. Based on feeding my own curiosity while preparing my production environment for NSX-T I decided to write this article. Below you will find high level overview of components and the two tier routing topology. Routing can be defined in the following directions: … Explore: NSX-T Routing 101
It feels like I cannot go a week without being asked the question of, “What is my real capacity on vSAN/VxRail?” Followed by we just cannot get our capacity planning correct and we are determining how much more capacity to grow our cluster by. I thought I would perform a back to basic vSAN math … Explore: VxRail / vSAN Capacity Math Made Easy
NSX-T Manager Controller provides the graphical user interface (GUI) and the RESTful API for creating, configuring, and monitoring NSX-T components, such as logical switches. NSX-T Manager Controller implements the management plane for the NSX-T infrastructure. It provides an aggregated system view and is the centralized network management component of NSX-T.

This is my fourth and final installment of this series. These steps were taken by me to failover and failback multi-million dollar datacenters in as easy as 4-clicks. At this point we should have our SDDC deployed and linked back to our onprem. VR/SRM should be deployed both onprem and in the SDDC. All site … Explore: Part 4. DRaaS – The four click failover…
Recently, I have been getting a lot of questions around how to build vSAN for high performing workloads. This article is intended to cover hardware differences, slack space, what is vSAN namespace, object, component, Raid-1 vs Raid-5/6, and stripe width, which all can impact performance. Please keep in mind I am not covering dedup/compression overhead … Explore: Performance Tuning your vSAN / VxRail Environment
I wanted to cover real quick creating a custom storage policy on vSAN, which even on a VxRail is done in vCenter. House keeping items:Raid 1 mirror is where you write a complete replica of the object. This is the highest performance protection you can apply to an object. Since it is a complete replica … Explore: Create a new vSAN Storage Policy in vSphere…
In my previous article I showed everyone how to install the latest vCenter 6.5 U2d. Now I will show how to upgrade your existing vCenter to 6.5 U2b and why created new vCenter’s with embedded Platform Services Controllers will make upgrades even easier. Before we begin, always remember to take a snapshot before upgrading any … Explore: Upgrade vCenter with external PSC to 6.5 U2b
As we are all aware vCenter is at the heart of our vSphere environments. Whether deploying a lab or a net new datacenter with vSAN/VxRail, you will require a new vCenter. Before I begin, embedded vs external Platform Services Controller (PSC). I say treat any net new install as embedded PSC only. VMware is in … Explore: How to Install a vCenter (VCSA) 6.5 U2d
This is the third installment of my ongoing series on DRaaS. We have have by now installed VR/Site Recovery Manager, configured site pairings, and configured onprem and SDDC mappings.
