One of the new, exciting features in vSAN 7.0U1 is the extension to vSAN File Service. As well as supporting NFS v3 & v4.1, we now also support SMB (Server Message Block) protocols v2 & v3. This protocol is commonly associated with Windows File Shares. In this post, I will go through the new configuration steps, and then we shall present the new created SMB file share to a Windows desktop. One of the new prerequisites, which wasn’t needed with NFS file shares, is that Active Directory integration is required for SMB. We will see this new step during the…
I’ve spent a lot of time recently on creating and building out vSphere with Tanzu environment, with the goal of deploying a Tanzu Kubernetes “guest” cluster. I frequently used the kubectl-vsphere command to logout of the Supervisor namespace context and login to the Guest cluster context. This allowed me to start deploying stateful and stateful apps in my Tanzu Kubernetes Guest cluster. I thought no more about this step until a recent conversation with my colleague Frank Denneman. He queried whether or not Kubernetes developers would actually have vSphere privileges to do this. It was a great question which led…
One of the new features introduced in vSphere 7.0U1 is HCI-Mesh, the ability to remotely mount vSAN datastores between vSAN clusters managed by the same vCenter Server. My buddy and colleague Duncan has done a great write-up on this topic on his yellow-bricks blog. In this post, I am going to look at how to address the situation of selecting the correct vSAN datastore when provisioning Kubernetes Persistent Volumes in an environment which uses HCI-Mesh. This will address the support statement in the vSAN HCI-Mesh Tech-Note that states that the following use case is not supported: Remote provisioning workflows for…
With the release of vSAN 7.0U1, a major change was made with regards to what was termed “slack space” requirements. This basically referred to how much space should be set aside on the vSAN datastore for operational and rebuild purposes. I have had a few queries about this recently, so I thought I would take the opportunity to highlight some of the capacity management features now available in vSAN. This would also be a good time to revisit the advanced options for Automatic Rebalance, as well as discuss the Reactive Rebalance features that we have had in vSAN for some…
I’m sure most readers are now aware that we now have 2 versions of what was initially called “Project Pacific” at VMworld 2019. Our initial release with vSphere 7.0 (vSphere with Kubernetes) was only available with VCF & NSX-T. However, with the release of vSphere 7.0U1, whilst we continue to have VCF with Tanzu, there is a new version outside of VCF called vSphere with Tanzu. I have written about how to get started with this new version, from covering the prerequisites, deploying a HA-Proxy, enabling vSphere with Tanzu Workload Management and deploying your first TKG ‘guest’ cluster. In this…
At VMworld 2019, I had the pleasure of presenting our business unit’s Spotlight session with our GM, John Gilmartin (you can watch the complete recording here). One of the topics that generated a lot of interest was a low-cost Disaster Recovery (DR) service. A lot has happened in the past year but most notably was the acquisition of Datrium. Merging the original goal of a low-cost DR as a Service (DRaaS) solution alongside the smarts acquired from Datrium, we are now almost at the point where we are ready to deliver a new VMware Cloud Disaster Recovery service to our…
In a previous video, we looked at the steps involved in enabling vSphere with Tanzu / Workload Management. That video concluded with the creation of a vSphere Namespace. In this video, we will demonstrate how to login to the namespace, how to create a Tanzu Kubernetes Grid (TKG) ‘guest’ cluster via a simple manifest / YAML file, and then how to change contexts so that a developer can work in the context of the new TKG guest cluster. This video accompanies a more detailed write-up on deploying a TKG guest cluster in vSphere with Tanzu.
