VCF on VCD: vSphere Replication

VCF on VCD: vSphere Replication

Comments 0 Comment

Because I have had some issues with my lab in the past (having to rebuild it a couple of times) I switched my storage to iSCSI (see https://my-sddc.net/vcf-on-vcd-iscsi-configuration/), but I also wanted to have another means of redundancy and for that I am using vSphere Replication. I will replicate my two VCF instances to each other. The following setup is what I will be aiming for: So the “odd” volumes are Production and the “even” volumes are Replication (I will…

VCF on VCD: iSCSI Configuration

VCF on VCD: iSCSI Configuration

Comments 1 comment

Because my lab has seen a couple of failures, with regards to storage, I got the advice to move my Management VM’s away from the vSAN, since a distributed storage layer on top of a distributed storage layer is not the best option, from a availability perspective. So I have been building a couple of Truenas iSCSI servers, in order to store my VM’s there and at the same time configure some replication, so I am safe from any issues…

vSAN and vSphere compatibility differences

vSAN and vSphere compatibility differences

Comments 0 Comment

In my work, I am often doing updates for customers that are not using VMware Cloud Foundation. And when doing these updates, it is very important to be aware of the differences in compatibility between vSphere and vSAN. They both use the drivers that are installed by the update process, from Update Manager or Lifecycle Manager, but they maintain different Hardware Compatibility Lists. When I did an update of vSphere for a customer, deploying the latest updates from vSphere, I…

After creating the NSX Managers (Local and Global, see https://my-sddc.net/nsx-t-global-manager-installation-and-initial-setup), and receiving the goods I ordered for the nested hosts, it is time to begin building the basics for the new lab. I have the availability of one HP DL380p Gen8, with two processors and 384 GB of memory. Two 450 GB 10K SAS disks for the basic virtual machines (vCenter, NSX-Manager and such) and I added two time three SSD’s. The idea behind this, is that I will create…

New Lab – Part 2 – Setup and some small tips & tricks

Comments 0 Comment

For my lab environment I am building on a combination of physical and virtual. I have one (massive, from home lab perspective) DL380 on which I will run multiple nested environments and I have one PC with a fair amount of memory, which will host some virtual machines, that will help me along. Setup Basically, I am working towards the following setup (for now): All of this is connected to a NetGear switch (not to fancy, but support for VLAN’s…

New lab environment – Part 1 – vCenter Server install on VMware Workstation

New lab environment – Part 1 – vCenter Server install on VMware Workstation

Since my company has moved offices recently (during the COVID-pandemic), the availability of my demo (/lab) environment has been cut off. This was okay for a couple of weeks, but it has been a couple of months now, and I really miss the possibility to test out some things. So I decided to get myself a new homelab. The lack of lab-equipment also stopped me blogging for quite some time, but since we are in the summer vacation, I plan…

Repointing embedded vCenter server to join existing SSO-domain, for Enhanced Linked Mode

Repointing embedded vCenter server to join existing SSO-domain, for Enhanced Linked Mode

Comments 0 Comment

I was running a demo environment with three separate vCenter Servers, because of historical reasons. At one stage I wanted to migrate some VM’s from on to the other. Two choices exist, one is the Cross vCenter vMotion fling (very useful, find it here), the other is joining two (or more) vCenter Servers into one environment, by using Enhanced Link Mode (ELM). I chose the second option, because that would give me other advantages as well. To do this, we…

vSphere 7 and VCF 4.0: evolution or revolution?

vSphere 7 and VCF 4.0: evolution or revolution?

Comments 2 comments

When looking at the new version-numbers of both products, you might think, “a major update, but going further along an already well-trodden path”. Well, you would think wrong. The newest additions to VMware’s SDDC portfolio do have new features and functions (and lots of them), but they are also very much changing things around and giving customers the possibility to focus on the technology that is taking the world by storm. Modern Applications So terms like DevOps and Modern Applications…
