New Book: VMware vSAN 8.0U1 Express Storage Architecture now available

I am delighted to announce the availability of a new book, VMware vSAN 8.0U1 Express Storage Architecture. Along with my colleagues, Duncan Epping and Pete Koehler, we have updated the vSAN deep dive book to focus on the new vSAN architecture which was announced with the vSphere & vSAN 8.0 releases. We held off publication as we were aware of a number of upcoming enhancements in 8.0U1. Now that this release is generally available, the book includes all of the new features and functionality found in the 8.0U1 release. Please note that we made a decision not to focus on…

VMware Explore 2022: What’s new in vSphere 8 & vSAN 8

VMware Explore 2022 kicked off this week. There are of course many announcements taking place across the whole suite of VMware products. In this post, I will focus primarily on the announcements related to the products that I work with on a regular basis. Those products are vSphere 8, vSphere Tanzu Standard (vSphere with Tanzu), and vSAN 8. vSphere 8 In the vSphere 8 space, the most significant announcement in my opinion is the fact that we are delivering on Project Monterey. We got our first technical preview of Project Monterey back in 2020 by the VMware CTO, Kit Colbert.…

A closer look at vSphere+ and vSAN+

At this stage, I guess that most readers will already be aware of the recent announcement around vSphere+ and vSAN+. I’m sure many readers are also aware that VMware is on a multi-cloud journey, with a goal of offering the benefits of cloud to on-premises vSphere deployments. vSphere+ and vSAN+ are some of the first steps we are taking at VMware to make this goal a reality. So what advantages does vSphere+ and vSAN+ give to customers? In this post, I will attempt to highlight some of those benefits. Centralized Management First and foremost, vSphere+ offers a new mechanism for…

vSAN Data Persistence platform (DPp) Revisited

Around 18 months ago, I published an article which highlighted a new feature called vSAN Data Persistence platform, or DPp for short. Basically, it describes a set of vSphere services built into vSphere with Tanzu. There are a few changes since I last wrote about it. For that reason, I thought I would revisit it. I am going to use my recently updated vCenter Server version 7.0.3e (build 19717403), and vSphere with Tanzu Supervisor Cluster v1.22. In this post, I will go through the new steps that demonstrate how to install MinIO as a vSphere Service. I will then show…

Announcement! vSAN Deep Dive book updated for 7.0 U3

I am delighted to announce an updated version of the vSAN Deep Dive book. It’s been a while since we did an update to this book. The most recent version was for vSAN 6.7 U1. A lot has changed since then. We’ve seen the arrival of some significant features such as vSAN File Service and HCI-Mesh.  We have also seen vSAN positioned as a platform for Cloud Native Applications through integration with the vSphere CSI driver and Kubernetes. There have been plenty of other enhancements such as Compression Only support, Durability Components and changes around Capacity Management and reservations. In…

Kubernetes, vSAN Stretched Cluster with CSI driver v2.5.1

In this post, we will look at a relatively new announcement around support for vanilla or upstream Kubernetes clusters, vSAN stretched cluster and the vSphere CSI driver. There are a number of updates around this recently, so I want to highlight a few observations before we get into the deployment. First of all, it is important to highlight that a vSAN Stretched Cluster can have at most 2 fault domains. These are the data sites. While there is a requirement for a third site for the witness, the witness site does not store any application data. Thus all of the…

vSAN File Service backed Persistent Volumes Network Access Controls [Video]

A short video to demonstrate how network access to Kubernetes Persistent Volumes, that are backed by vSAN File Service file shares, can be controlled. This allows an administrator to determine who has read-write access and who has read-only access to a volume, based on the network from which they are accessing the volume. This involves modifying the configuration file of the vSphere CSI driver, as shown in the following demonstration. The root squash parameter can also be controlled using this method. This links to a more detailed step-by-step write-up on how to configure the CSI driver configuration file and control…
