On the flip side, I have only had four USB keys go bad on me in 11 years with 13 servers. It is not a big sample size but it is something.
WOW - that's huge! nearly 30% failure...
Yeah. The previous admin used shitty USB keys. Once I switched to Sandisk, I have not had any problems. One was and old USB key with a microcenter label, the other three were Transcend. Man, those SUCK!

@pmoncho how do you deal with USB or SD card failures in this instance? Is there a way to program a replacement or would it be as easy as re-downloading ESXi onto another USB/SD and inserting that as a replacement?
Does your Dell have the SD card reader? If so, it runs the SD cards as a RAID1 array.
I haven't installed ESXi myself ever (to expensive too quickly once you get into "I have to license this"). I'd want to use 2 usb drives in a mirror if going the usb route, but don't know if that is easy or possible with the installer.
-
@travisdh1 it doesn’t. I know if you order them specifically for ESXi then they ship it with either an SD or USB (can’t remember which) that’s already setup as RAID 1. Definitely a detail to remember for the future. Pushing hard to go Virtual after this last Ransomeware hit.

Here's a KB that matches the virtual machine hardware versions with product versions like you see when you try to create a VM - https://kb.vmware.com/s/article/1003746.
Here's a list of capabilities that match to different virtual machine hardware versions - https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.vm_admin.doc/GUID-789C3913-1053-4850-A0F0-E29C3D32B6DA.html.
So if you created a VM that was compatible with 6.7U2, it could not run on a host running any version of ESXi older than 6.7U2. In your case that won't be a problem since you are just getting started, but it is something to keep in mind if you build an environment with hosts on newer versions of ESXi later and want to move things around. Keep the VM hardware version at the right level for max flexibility / compatibility in the environment.
-
Also, just for due diligence, I recommend checking the power profile on the server and ensure it is set to max performance. Turn off processor C-states as well to ensure you get all the firepower that host can give you. There's a host power power management policy setting in ESXi for each host that you can set to high performance as well.

@NetworkNerd, @pmoncho , I'm still having no luck over here. I've tried 6.5, 6.7 and 6.7 U2. All with Dell ESXi and without. Dell is saying that they think it's because this specific server doesn't have a PERC cache. Does that sound like nonsense to you all or not? I know the previous machine (which I had 0 zero issues other than forgetting to install VMWare Tools on initially), worked fine, but it DOES have a PERC cache...

Which RAID card do you have in the server according to the BIOS or iDRAC?

Well, they are right that the PERC H330 does not have a cache. Based on a few google searches, others have had similar issues with this card depending on the RAID level.
So, what type of drives do you have and what RAID level are you using?

RAID 5, 7 - 1TB Intel SSD, shipped with the Server.

@pmoncho, @NetworkNerd, @travisdh1, @Dashrender, @DustinB3403, @marcinozga - Thanks for your help. After reading an article on it or two and talking with Dell, We're ditching the H330. Boss just ordered the H730P.

That, in the long run, is probably the best call. Any way you can get the boss to add on the SD Card module? That will be a benefit also if you stay with ESXi.
-
When you were trying to copy files and so forth, were you viewing the Disk Monitor on the host? If so, did you notice abnormal latency?
-
@pmoncho There were a lot of spikes.

The H330 is like for labs or testing. Shouldn't be found in a production environment. It's a fine card for what it is, just not a production use card

Yeah, that's definitely the way to go. You need the CPU and cache of that card.

haha, yes. Working on that as we speak.

Sweet. Keep going. See if your boss can get iDRAC enterprise license if you don't have that. Not really required but it is nice to have.

Begs the question why when ordering a server for a specific purpose, they would even ship that out.
