HOW TO: Configure & Install VMware ESXi ARM 8.0.3b on Raspberry Pi CM4 installed on a Turing Pi v2 Mini ITX Clusterboard | FULL MEGA GUIDE

Tuesday, December 3rd, 2024

Welcome to Hancock’s VMware Half Hour! This is the Full Monty Version, the MEGA Full Movie on configuring and installing VMware vSphere Hypervisor ESXi ARM 8.0.3b on a Raspberry Pi Compute Module 4. The CM4 is installed in a Turing Pi v2 Mini ITX Clusterboard, delivering a compact and powerful platform for ARM virtualization.

In this 1 hour and 19-minute guide, I’ll take you step-by-step through every detail, covering:

? Demonstrating Raspberry Pi OS 64-bit booting on CM4.

? Creating and installing the ESXi ARM UEFI boot image.

? Configuring iSCSI storage using Synology NAS.

? Setting up ESXi ARM with licensing, NTP, and NFS storage.

? A full walkthrough of PXE booting and TFTP configuration.

? Netbooting the CM4 and finalizing the ESXi ARM environment.

? Flashing the BMC firmware is covered in this video

? Replacing the self-signed Turing Pi v2 SSL certificate with a certificate from Microsoft Certificate Services. is covered in this video

Part 56: HOW TO: Manually remove a failed vSAN disk group from a VMware vSphere vSAN cluster using ESXCLI

Monday, November 25th, 2024

In this video presentation which is part of the Hancock’s VMware Half Hour I will show you HOW TO: Manually remove a failed vSAN disk group from a VMware vSphere vSAN cluster using ESXCLI.

 

The VMware vSphere vCenter Server web client has difficulty in performing some vSAN actions, so we need to connect via SSH to the bash shell of the ESXI host to perform this action using the following command

esxcli vsan storage remove -u <VSAN Disk Group UUID>

Part 48. HOW TO: Add a VMware vSphere vSAN license to a VMware vSphere vSAN Cluster

Saturday, October 19th, 2024

In this video presentation which is part of the Hancock’s VMware Half Hour HOW TO Video Series I will show you HOW TO: Add a VMware vSphere vSAN license to a VMware vSphere vSAN Cluster.

The storage devices we are using in this video are the Intel® Optane™ SSD DC P4800X Series 375GB, 2.5in PCIe x4, 3D XPoint™, but this procedure can be use to add any compatible storage devices in ESXi to a vSAN datastore.

This video follows on from the follow video in this series

Part 36: HOW TO: Select an inexpensive HCL Certified 10GBe network interfaces for vSphere ESXi 7.0 and vSphere ESXi 8.0 for VMware vSphere vSAN

Part 37: HOW TO: Change the LBA sector size of storage media to make it compatible with VMware vSphere Hypervisor ESXi 7.0 and ESXi 8.0.

Part 39: HOW TO: Create a VMware vSphere Distributed Switch (VDS) for use with VMware vSphere vSAN for the VMware vSphere vSAN Cluster.

If you are creating a design for VMware vSphere vSAN for a Production environment, please ensure you read the  VMware Cloud Foundation Design Guide 01 JUN 2023 – this should be regarded as The Bible!

Part 39: HOW TO: Create a VMware vSphere Distributed Switch (VDS) for use with VMware vSphere vSAN for the VMware vSphere vSAN Cluster.

Saturday, October 12th, 2024

In this video presentation which is part of the Hancock’s VMware Half Hour HOW TO Video Series I will show you HOW TO: Create a VMware vSphere Distributed Switch (VDS) for use with VMware vSphere vSAN for the VMware vSphere vSAN Cluster.

VMware vSphere Distributed Switch (VDS) provides a centralized interface from which you can configure, monitor and administer virtual machine access switching for the entire data center. The VDS provides:

  • Simplified virtual machine network configuration
  • Enhanced network monitoring and troubleshooting capabilities
  • Support for advanced VMware vSphere networking features

As my 10GBe switch in this VMware vSphere Lab has LACP functionality I have decided to demonstrate how we configure the vDS for a LACP LAG. Link Aggregation Control Protocol (LACP) is one elements of an IEEE specification (802.3ad) that provides guidance on the practice of link aggregation for data connections, it’s used on trunks or port channels, to bond two ethernet ports together. It is only supported using a VMware vSphere Distributed Switch (VDS) , it is not supported on a VMware vSphere Standard Switch (VSS).

This video covers the following

  • Creation of the VMware vSphere Distributed Switch (VDS).
  • Creation of Portgroups with vLANs for Management, vMotion and vSAN.
  • Creation of the LACP LAG.
  • Adding vDS to hosts in the vSphere Cluster.
  • Migration of existing VMKernel portgroups from VSS to VDS.
  • Testing the VMware vSphere Distributed Switch (VDS).

If you are creating a design for VMware vSphere vSAN for a Production environment, please ensure you read the  VMware Cloud Foundation Design Guide 01 JUN 2023 – this should be regarded as The Bible!

3..2..1.. and Success (don’t try this at home kids)

Saturday, September 18th, 2010

After another few failed attempts, and some diagnosis, it was the sealed lead acid battery that wasn’t providing enough power (Amps) to fire the rocket cluster. I tried charging the battery with a car battery charger and that went horribly wrong and smelly, and the plastic case melted on the battery, because my special charger for the seal lead acid battery had also failed.

So I purchased a new sealed lead acid battery and here are the results

Quick disclaimer (don’t try this at home kids), you could get seriously hurt!

This test was to check the rocket mounts were secure to hold in the two rocket motors, before further completing the rocket assembly. You can clearly here the warning tone before firing the rocket motors, both rocket motors ignite simultaneously, the rockets both burn at a constant rate, until the ejection charge which would normally deploy the recovery mechanism, e.g. a parachute is heard.

Looking back at the video, I think there is a slight delay between the rocket motors!

3..2..1.. and nothing… Umm

Monday, August 30th, 2010

Now that the UK has relaxed it’s Rocketry and Explosives requirements, it’s a little easier to acquire and use rocket motors in the UK, without all the red tape and certificates, and explosives license.

so back to Model Rocketry….

Before I complete the rest of this rocket, I’m testing the motor mounts, before adding fins and painting, it’s very important to ensure that the motor mounts are fixed and glued correctly within the body of the rocket, otherwise the motors when ignited will just seperate from the model rocket body.

Test Number 1. 3..2..1.. and nothing… Umm

Time passes and sometime later that evening….. (it’s getting dark now).

Test Number 2. 3..2..1.. and nothing… Umm

Damn Damn and Fecking Damn!!!

Back to the drawing board, electrical issues maybe……not firing….

Well it’s Rocket Science you know!
