TKG & vSAN File Service for RWX (Read-Write-Many) Volumes

A common question I get in relation to VMware Tanzu Kubernetes Grid  (TKG) is whether or not it supports vSAN File Service, and specifically the read-write-many (RWX) feature for container volumes. To address this question, we need to make a distinction into how TKG is being provisioned. There is the multi-cloud version of TKG, which […]

vSAN 7.0U1 – File Service SMB Support

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 […]

vSAN File Services and Cloud Native Storage integration (Video)

In this short video, I want to show some of the integration points between vSAN 7.0 File Services, and Cloud Native Storage (CNS). We will use the CSI driver that ships with vSphere 7.0 to provision a new read-write-many persistent volume backed by a vSAN file share. A read-write-many persistent volume is one that can […]

I thought this was controlled by the accessModes parameter in the PersistentVolumeClaim manifest file. This is not the case. It is controlled from the Pod, which to me seems a bit strange. Why would this not be […]

Using Velero to backup and restore applications that use vSAN File Service RWX file shares

It has been a while since I looked at Velero, our backup and restore product for Kubernetes cluster resources. This morning I noticed that the Velero team just published version 1.4. This article uses the previous version of Velero, version is v1.3.2. The version should not make a difference to the article. In this post, […]

Read-Write-Many Persistent Volumes with vSAN 7 File Services

A few weeks back, just after the vSphere 7.0 launch event, I wrote an article about Native File Services in vSAN 7.0. I had a few questions asking why we decided on NFS support in this initial release, and not something like SMB or some other protocol. The reason is quite straight-forward. We are positioning […]

Native File Services for vSAN 7

On March 10th 2020, we saw a plethora of VMware announcements around vSphere 7.0, vSAN 7.0, VMware Cloud Foundation 4.0 and of course the Tanzu portfolio. The majority of these announcements tie in very deeply with the overall VMware company vision which is any application on any cloud on any device. Those applications have traditionally […]
