ESXi recommends SD card, USB is a bit to fragile for the number of writes you'd be making to it.
M.2 SSD is the recomendation. SD cards lack any kind of ECC and the controllers are too dumb to prevent read discards. Throw in the fact that cheap SD cards are slow on boot, you can log local on a M.2, I'd say for non-lab usage M.2 is the recomendation going forward.
If you must go embedded SD card, I'd get at least 32GB as it will likely have fewer read endurance issues.
are servers starting to come with M.2 slots specifically for this? that would make sense - it also makes booting systems much easier I would think.
I have not seen any M.2 on dell servers yet. With that being said, they R840 the OP has, there are two rear 2.5" SATA (HDD/SDD) bays that may/may not be used for a boot device. Have not looked to find out if it is possible though.
yeah, I've seen servers in the past with internal HDD/SSD, it only makes sense to keep moving forward and put M.2 in there for this purpose - I would assume less space needed in chassis, less power consumption, less cooling possible, etc.

All 14G servers AFAIK support adding in a "BOSS" card that has 2 M.2 slots.

"By putting it on the motherboard, it just seems like a way to charge everyone who doesn't use for it
An H330 is going to cost you about the same, and wastes 2 drive slots.
FWIW VxRAIL uses BOSS for boot as of 14Gen so there is a decent volume of them in production (For 13Gen they used a high endurance SATADOM device). -

Some SBCs do that, too. Like the Pine64 upper end card.

What kind of RAID did you set the drives on?
How much RAM?How did you setup the VM? How much storage, ram, vcpus?

I’m at home now, but will try to answer to the best of my ability until I get back.
- RAID 5
- I tried ESXi 6.5, 6.7 & 6.7 U2, with Dell OEM 6.7 U2 on host.
- I originally was doing 20GB RAM, 2.5 TB HD, but later tried more basic 16GB RAM, 500GB HD
- CPU 2 Socket 2 core and 4 socket 1 core really just mixing it up at this point hoping anything will be different.
- I tried selecting SCSI Controller VMWare Paravirtual, but when I install VMWare Tools to load the driver so I can see the Partitions, it only lets me select the AMD64 which is wrong. Then it tells me I can’t install windows on the partition. So I was using the default LSI Logical SAS.
I made sure Virtualization was on in BIOS, and tried turning on Turbo, but not getting anywhere as of yet.

RAID 5
Why raid 5 today with all of the evidence that it's dead tech. Are these SSDs that makeup the array?

My boss configured the RAID, and yes they are SSD’s.
Would you recommend 10?

Additionally, I just got them to buy me some Thumb Drives (verbatim 32 GB). Thinking of running RAID 1 on those for ESXi (is it possible to do that with one partitioned USB or maybe that’s a bad idea because if the thing fails it all failed right?). At least until we can get an internal M.2 or SD setup going.

RAID 5 on SSD should be fine. It's the old-fashioned spinners that the major issues exist with.

Yeah with an SSD array you're fine, but with spinning rust I'd consider RAID 6 or RAID10

How could AMD64 be wrong? What other possibility is there? VMware only runs on AMD64.
What are you running? You don't have a Power or Itanium system, do you?

Not likely, RAID 5 is perfectly fine there. RAID 10 is likely overkill. But RAID 5 definitely would push you to a powerful RAID card.

That doesn't change anything. It's a licensing thing, not a tech thing.

For s&h why not try Hyper-V as the hypervisor, then setup a Windows VM

S&H, not Ss&Gs?

If you are going to try something, try KVM. Faster, easier, less likely to have weird things happen. Hyper-V is good, but if you are starting over, might as well make life as easy as possible.

I was assuming the driver should have been the Intel driver (as that’s an option too) because I have an Intel Xeon, but you’re saying it’s for use by ESXi, for ESXi and not for use by ESXi for the chipset installed. I guess I misunderstood that.
