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 vSAN as a platform for both traditional virtual machine workloads and newer containerized workloads. We chose NFS to address a storage requirement in Kubernetes, namely a way to share Persistent Volumes between Pods. To date, the vSphere CSI driver only provisioned block based Persistent Volumes…

Track vSAN Memory Consumption in vSAN 7

One of the most common requests in relation to vSAN performance is how much CPU and memory does vSAN actually consume on an ESXi host, i.e. what is the overhead of running vSAN. Through the vSAN Performance Service, we have been able to show both host and vSAN CPU usage for some time. However, up to now, we have only been able to show host memory usage, and not overhead attributed to vSAN. It has also been extremely difficult to determine how much memory vSAN required.  Way back in 2014, with the first vSAN version 5.5 release, I wrote this…

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 been virtualized applications. Now we are turning our attention to newer, modern applications which are predominantly container based, and predominantly run on Kubernetes. Our aim is to build a platform which can build, run, manage, connect and protect both traditional virtualized applications and modern containerized…

A holiday promo for the vSAN 6.7U1 Deep Dive Book

A very short post to let you know that Duncan and I are doing a holiday promotion for our vSAN 6.7U1 Deep Dive book. We will start the promotion for the e-book on December 24th, when we will lower the price of the e-book to just US $0.99 (Amazon.com) and UK £0.99 (Amazon.co.uk). The price will then gradually rise back to the original price over the following 10 days. Unfortunately, Amazon does not allow publishers to create promotions on every site, so this promotion will only be available on Amazon.com and Amazon.co.uk. For the paper copy of the book, we…

CNS – not just for vSAN

After a very eventful VMworld, we received lots of questions about CNS, the Cloud Native Storage feature that was released with vSphere 6.7U3. Whilst most of the demonstrations and blog articles around CNS focused on vSAN, what may have been missed is that this feature also works with both VMFS and NFS datastores. For that reason, I decided to create some examples of how CNS can also bubble up information in vSphere about Kubernetes Persistent Volumes (PVs) created on both VMFS and NFS datastores. Let’s begin by creating some simple policies to tag my VMFS datastore and my NFS datastore.…

Video of HCI Spotlight Session from #VMworld now available #HCI3551KE

This week at VMworld in Barcelona, I was honored to  be able to  co-present the HCIBU Spotlight Session with our GM and SVP, John Gilmartin. I noticed that the full video is now available online on the VMworld Video site. If you want to learn more about how to Future Proof your Infrastructure with vSAN and VMware Cloud Foundation, give it a watch. The cool demos, showing Cloud Native Storage, Site Recovery Manager support for vVols and Project Magna auto-tuning vSAN all start around the 30 minute mark. The full video is available here. Enjoy!

Recording of my VMUG France presentation now available

Last week I had the pleasure of presenting at the French VMware User Group (VMUG) meeting in Paris. The local VMUG team did an awesome job with respect to the logistics, and even had someone on-site to record all of the sessions. The team just sent me the recording of my presentation, which I am delighted to be able to share with you. If you’re interested in learning more about vSAN 6.7U3, Kubernetes and Cloud Native Storage, this recording should help. And don’t worry – only the first few sentences are in my very terrible French 🙂 Encore merci équipe…
