Running VCF 9 in a Nested Lab using vSAN ESA on a single host is that not great?

For the deployment I used a server that has 16 cores en 32 cores total and a lot of ram!

Installation on Nested ESX VM’s

For the nested ESX VMs I am using the generic ESX image. In my lab I’m using 4 nested ESX nodes for vSAN ESA (Minimum is needed is 3).

  • Ideally add 24 vCPUs to the nested ESX, but VCF Automation is capable of being deployed with 16 vCPUs
  • Check Expose hardware assisted virtualization to the guest OS under CPU
  • Add a NVME controller and connect disks to this controller if planning to use vSAN ESA (Don’t forget to remove the old Controller)
  • Add at least two VMXNET3 nics connected to the same network
  • Choose VMware ESXi 8.0 or later as the Guest OS version.
  • Change the IDE CD-ROM to SATA ROM (Failed to locate kickstart on Nested ESXi VM CD-ROM in VCF 9.0)

Config the 4 Host for vSAN ESA

To config the 4 Hosts for vSAN ESA I used my own powercli script where I blogged about here: Config vSAN ESA host or VCF ESA vSAN Host the easy way with Config-VSAN-ESA-VCF-Lab-Host Script

You can download the script HERE!

Installing the Vib works still great. No problem with ESA  Pre-check: ✅

If you have problems check this great blog from William Lam: vSAN ESA Disk & HCL Workaround for VCF 9.0

VCF installer.

At first you have to deploy the VMware Cloud Foundation

The name of the installer is a little off: VCF-SDDC-Manager-Appliance-9.0.0.0.24703748.ova

Download token

If you don’t have a download token from the Broadcom support then it’s a little complicated. I won’t go into this in depth now but here is a nice article if you have a Synology Nas: VCF 9.0 Offline Depot using Synology

(Note: For any vExpert reading this… You need to claim your own domain name because build your profile is not working with a @hotmail.com or @gmail accounts, Noted by Broadcom)

I looks something like this!

10GBE Nic Pre-Check Issue

Next thing to do was: Disable 10GbE NIC Pre-Check in the VCF 9.0 Installer or this should also work: How to change the vmxnet3 link speed of a VM (Not tested)

Deployment

I have deployed the beta in a earlier state. For deployment I used the same json file to start with.

VCF Automation will deployed automatically that was only the change that I changed it

Performance running Nested!!

Above the screenshot from the host with de Nested VCF lab deployment it’s quite cpu intensive (2 x CPU 8cores / 16 Threads)

Optimalization

After the deployment I did three things
– On the vSAN ESA Cluster (Disable Auto Disk Claim) (Keep the warning away)
– On the NSX VM reduce the cpu reservation from 6000 🡪 2000 (It helps but not enough)
– VCF automation VM 24 cores to 16 cores.

NSX en VCF automation are really CPU intensive.

I had deployed also two Edge servers but the server did not like that. Edges are also CPU intensive.

I am thinking about adding MS-01 or MS-A2 for splitting some load.
