Hi, I was wondering if anyone here knows how to boot up Esxi 7.0 on a m.2 or even if it is possible? Because I want to use M.2's instead of regular SSD drives. My Supermicro motherboard does not support any M.2 onboard, that is why I bought a PCIE 4 to M.2 adapter to support my M.2.

Of course you can however why would you boot off your fastest media? Remember you burn the boot device in esxi and are prevented from utilizing it as a datastore later. So the general use case is to boot off a satadom or USB and save the m.2 for datastore media.

I think usb devices can't be used to store vms, other block devices should work without problem.

Ah.. have not used USB devices in years - vCenter logging killed them all. Cheap old Intel enterprise SSDs it is:)

I've recommended the use of local SSD for booting ESXi for years now, because of mainly K.I.S.S.

For Prod = Dual SSD on B.O.S.S (Boot Optimized Server Storage)
Recommend Size = 200GB+ or more = more chance of being "Future Proof"
All Self-Contained, easier troubleshooting for when murphy shows up and have to rely on local logs :)

For my Homelab, I've using SM x10 2U Servers with 1 x Older 240GB SSD 2.5 SATA, had a few laying around, mounted them on an empty PCI slot with Startech Adapter, was pretty cheap & works great!

Here are some official sources / blogs / documentation:
