Hello,
i have a small lab environment with one ESXi 6.7 host booting from 256 GB SSD.
This works fine without problem.
No i have a system where i wanted to test if running from SSD is improving the performance.
So i started a "storage vmotion" to move the VM to SSD, where the vmfs datastore is available.
I have the problem that the copy is soooooo slow, that i do not think this is a good idea.
Can it be, that ESXi is limiting access to the datastore so extremely "by design"?
As there's no other performance problem with the host itself, i guess this can be the only reason.
Thx for giving me a hint.
Any write operation will be depended to source and destination speed.
May be, the source disk is the cause of slowness.
@DavoudTeimouri: this might be the cause but it's an Sasmung evo 860 SSD.
I could not see this slowness on boot or installing the host.
But i remember that there was some kind of "protection" in the esxi that would disallow some things to protect the hypervisor.
I will try to do some speedtest to check this out.
