Intel® i219-LM ESXi // lost access to volume successfully restored access to volume

Hello dear community,

I am importing (deploying) an OVF template to my host. Apart from the fact that it is damn slow it also looses the access frequently (please note the time stamp):

I am wondering what that is?

I already notice or figured out the LAN card has some issues with ESXi (or the other way around):

• ESXI 6.5 - Intel gigabit ct slow performance
• Re: Intel 82577LM should work out-of-the-box on esxi 6.5 but doesn't. Ideas, why?

That's the NIC I use:

• Intel® i219-LM Ethernet (10/100/1000)

Can the NIC issue cause the loss of access to the datastore or am I facing already the next problem?

Thanks for any advice
