My Software Defined DataCenter

I received a question from a customer. There were some issues with anti-affinity rules in their environment, where the status would stay on “Pending”, after they had created an anti-affinity rule for VM’s. In my lab-environment I tried this out as well and, at first, ran into the same issue. This is my environment: As you can see, I have two clusters, connected to one Prism Central. I usually have my lab shut down and power it on, when needed….

Besides Disaster Recovery with Prism Central, there is also Data Protection available in Prism Elements. So after setting up DR for the Windows VM’s in: https://my-sddc.net/disaster-recovery-with-prism-central/, I am trying something similar for the Linux VM’s, by leveraging Prism Elements. First step for this, is define the clusters as eachothers “Remote Site”: Here I can also directly create a mapping between Networks and between Storage Containers: After the Remote Sites have been set-up, I can create a “Protection Domain”, that contains…

Studying for the NCP-MCI exam, I ran into the fact that I needed to know more about Disaster Recovery. I did the training modules, but that doesn’t seem enough to pass the exam, I think. I took some of the available test exams on Nutanix University and felt that some hands-on experience would be necessary. I already have two clusters set-up, so I am going to protect some VM’s from both clusters to the other and try and get some…

I’m following a course to get myself certified on the Nutanix Tech and one of the topics I ran into, was migrating with Nutanix Move. So I thought, besides do the module, I would also try it out for real. So I started with downloading and installing the Move appliance on my Nutanix cluster: I am using the following sequence: Download Nutanix Move Well, that is easy enough. Just go to: https://portal.nutanix.com/page/downloads?product=move (if you have an account, with the right…

Na het succes van de vEUC TechCon, ontstond het idee om een vergelijkbaar evenement te houden over “Networking & Security” én over “Management & Automation” op het gebied van de VMware portfolio. Een aantal collega’s van vooraanstaande partners op deze gebieden is dan ook, in samenwerking met VMware gestart met de organisatie van twee technische conferenties om deze onderwerpen te belichten. En zodoende houden we op 25 september een vNS TechCon en op 26 september een vMA TechCon. Beide evenementen…

This morning, I woke a little early, because of the heat, so I went to my home office in the attick, and immediately saw the news I was waiting for, for some time, NSX 6.4.1 was released. Thanks to Martijn Smit, I could read all about it at http://lostdomain.org/2018/05/25/nsx-v-6-4-1-released-html5-vsphere-6-7-support-more/. So now, “finally”, the version of NSX that supports vSphere 6.7 has arrived, which means, time to update the lab. The benefit of waking early, so to say ;). The update process…

So another Sunday to add some stuff to my Ravello Lab. Last time I wrote about the basics, like vSphere, vSAN and NSX. I also added vRealize Log Insight at that point, configuring all the components to write their syslog entries to the appliance. Something not all of the vSphere and NSX customers know is that with both products comes the right to use vRealize Log Insight for free. For each vCenter server licensed, a 25 OSI-license for vRealize Log…

While in the process of deploying some management functionality to my Ravello LAB (see:  New virtual LAB on Ravello (part 1) and the second part coming), I ran into some issues with disk space. I had created a vSAN with approximately 800 GB of total space: When trying to deploy vRealize Operation Manager, I was told that there was not enough space. But fortunately the Ravello platform gives me the option to easily expand my vSAN. One node at a time,…

For a customer of mine, we are in the process of implementing a vSAN environment, where stretched clustering is used. They use a witness location, which is (independently) connected to both data-locations. For the vSAN networking, they do not use VRRP or another way to stretch there routing, but they do use stretched layer-2 networking. So their environment looks like this: In order to make sure that HA is handled correctly, it is advised to create a gateway-address within the…
