VMware vSphere VCSA 6.0 – 503 service unavailable via Web Client

I realized this by first checking the logs on the VCSA: SSH to the VCSA and run cat /var/log/vmware/vpxd Notice how there is some error connecting to SSO? Try to connect to SSO VMOMI endpoint Since I am using an external PSC, I then SSHd into that and checked the services with service-control --status --all As you can see above, the vmware-psc-client was not running so I...

VMware vSAN – Career changer?

Since starting my career in technology, I've always had a keen interest in virtualization. Over time, the virtualization of other datacenter objects has become more common and affordable. vSphere, Horizon View, NSX to name a couple have assisted with this. More recently vSAN has seen a lot of growth. Duncan Epping @DuncanYB, tweets about this growth periodically. The latest figures show 5000 vSAN customers which is a 200% growth year on year. What's interesting is that the growth looks to be increasing as customers gain more faith in the technology and VMware push out new features...

How can we achieve this? Luckily there is a very useful website over at https://www.cpubenchmark.net They determine a "PassMark" per CPU which grades a CPU on performance, the higher the...

The system cannot find the file specified VMware ESX cannot find the virtual disk "vm.vmdk". Verify the path is valid and try again.
