At VMworld last year, Duncan Epping and I presented on the power of Storage Policy Based Management (SPBM for short). You can find all of the slides and recordings here. One of the demos we used in the presentation was deploying virtual machines via vRealize Automation, and showing how to consume a storage policy on vSAN. This was using a vRealize Automation plugin, and to be honest, it was a little bit challenging to get it to work. And it wasn’t really a VMware plugin per-se, but something developed by our field team. Today, I’m pleased to announce that we…
At VMworld 2018, one of the sessions I presented on was running Kubernetes on vSphere, and specifically using vSAN for persistent storage. In that presentation (which you can find here), I used Hadoop as a specific example, primarily because there are a number of moving parts to Hadoop. For example, there is the concept of Namenode and a Datanode. Put simply, a Namenode provides the lookup for blocks, whereas Datanodes store the actual blocks of data. Namenodes can be configured in a HA pair with a standby Namenode, but this requires a lot more configuration and resources, and introduces additional…
Recently I was looking for a way to consume the Storage Policy Based Management (SPBM) cmdlets in PowerCLI. I wanted to see if I could provision a VM from a Template onto my vSAN datastore with a particular policy rather than simply change it after it was deployed. It wasn’t as easy as I thought, as some of the commands I tried would only change the VM Home Namespace to the new policy, and leave the disks with the default datastore policy. And when I tried to clone a new VM from a template, I couldn’t get the VM to…
As part of my preparation work for VMworld 2018, I was looking into how one might be able to automate the deployment of VMs from vRealize Automation 7.4 with an appropriate policy for consuming the under-lying storage. In my case, this underlying storage was vSAN 6.7 (and vSphere 6.7), so I wanted to be able to select a vSAN policy for my VM Home namespace and disks. Fortunately, there is a vRealize Orchestration (vRO) plugin to do just that called the vRA SPBM Integration plugin. But, once I had this plugin installed, and followed the instructions, I hit a snag.…
One of the great things about presenting at VMware User Group meetings is actually talking to customers and finding out about what their pain points are, and how VMware can improve on our products and features. At the most recent VMUG I attended (in Poland), I was asked a question about storage policies, and if there was a way to allow some users to use some policies, and other users to use a different policy. Unfortunately there is no permissions associated with policies at this time, so any user can select any policy. With that in mind, I had a…
Last week, I was presenting at the VMware User Group (VMUG) event in Poland. My topic was SPBM, Storage Policy Based Management. This is the framework for consuming data services, whether these are provided from vSAN, Virtual Volumes or VAIO (IO Filters). You can get the presentation from here. One of the attendees who had implemented Virtual Volumes (aka VVols) asked a very interesting question about changing policies of a VVol based VM on-the-fly. The question is whether a policy change causes a new VVol has to be instantiated, data synced to original VVol and then the original VVol is…
Last week I wrote about the new vSAN management pack for vRealize Operations. This week sees another nice new storage feature/solution released. This time it is a solution to integrate vRealize Automation and Storage Policy Based Management (SPBM). For those of you who saw the VMworld 2016 keynotes, you may remember Yanbing Li demonstrating the ability to have a VM move to a completely new datacenter, based on storage policy compliance. In essence, if a VM exits compliance with its storage policy (for whatever reason), vRealize Automation SPBM integration can initiate a migration of this VM to a completely different…
