UNICOM Engineering has identified specific vulnerabilities with IPMI interfaces
Don’t expose your IPMI to the internet. Actually don’t expose your TrueNAS GUI either.

well i dont portforward anything on pfsense. but i dont know enuff about ipmi to be confident 
Then it’s fine.

8 year old video. but he explains how to use it.
so how the heck do u assign static ip to the ipmi if u have to graphics card in first place to see bios?
or is it by default in bios ipmi is enabled. but its using dhcp? so ipmi will just work right off the bat?
so do you do a network scan, and look for a gigabyte leo, to know thats the ipmi ip?
Gigabyte Mainboard MC12-LE0
so for pcie here, the x16 use for the sfp+
then the x4 if to the m.2 nvme ssd (2 ssd) is this gonna work?
cant i just use this?
https://www.jeffgeerling.com/blog/2024/jetkvm-tiny-ip-kvm-thats-not-apple-watch
with jetkvm does that mean i also dont need graphics card or igpu to access bios on monitor? just plug in?
then i dont need to be hung up over ipmi motherboard. is that possible?
well i’ll just order the case first 
Yes, dhcp.
So you can see it in your pfsense leases, or you can run a network scan.
I’m not sure about gigabyte, but Supermicro has an app which will show the IPMIs in your local LAN.

These external network connected IP KVMs require graphics output from the motherboard.
The server grade BMC systems include a crappy VGA graphics card, which is what is connected to the internal IP KVM

this is the ddr4 ecc ram i found. 1 month warranty used. customers reported memtext showing it works without issue.
so 2 sticks of 16gb ddr4 3200mhz i guess.
*update
going through the thread. making sure i dont miss anything. appreciate every1s feedback 
how do u do this? do u mean undervolting?
i recently used pbotuner 2 on my desktop pc. this helped me keep temps 65c under. before it was maxing 83c
without rails, there is this shelf thing to add support for the 4u. not sure what would fit for my rack though 
my plan b, is to just sit the 4u on the flat shelf which i installed at the bottom of the rack 
but for convenience, the sliding rails would be pretty neat for upgrade/maintenance from time to time. this 4u is gonna be too heavy to derack. thats gonna be hell
hoping the seller has the rails and it fits *cross fingers
i was doing some research on cpu cooler. maybe this will help some
this is for thin profile cpu cooler for am5
but i’m needing for am4
Im between Shuriken 2 and Noctua L9a-x65 I’ve used scythe fans before (luv them), but i havent used noctua before though im aware they r good rep (yes shocking i know maybe now is a good time? but it always comes down to price)
but i need something for MATX. any suggestions for these 2 brands. what will work with the gigabyte leo board
useful reference it would look roughly like this i imagine

Normally CPU coolers are restricted by what sockets they support, rather than “boards”
Afterall, the CPU + Socket doesn’t know how much board is around it 
Although this is a gorgeous image

i got confused cauz the cooler product description said itx. not matx. so i figured it wouldn’t work
yes that looks great. im using a scythe fuma 2 for my main desktop pc. even my water cooling back in the day for 360 radiator i bought a couple scythe fans for it, works well.
i was checking the prices scythe was cheaper than noctua.
“ideally suited for ITX systems and other confined applications”
ie, ITX systems are confined… and this is good for confined systems… because its small. You can use it on an E-ATX board if you want.

here is part list so far
- ryzen 5600x (the spare cpu i have lying around)
- artic mx5 thermal paste (may have some left over which i can use. 5 dot pattern as per amd recommendation)
- ddr4 ecc ram. 16gb x2 3200mhz (used, 1 month warranty. other customer report good. but will run memtest to confirm myself. quite affordable)
- gigabyte leo motherboard am4 (confirming the price first)
- scythe shuriken 2 (maybe should get bigger cooler? not sure)
- RM41-H08 (4u rack case for the truenas)
- Seasonic focus + GX 750 psu (is this compatible with the motherboard? is 750 overkill?)
- seagate exos x12 12tb x 4 (5 year warranty international. probably recertified drives. good customer reviews though)
- 3x m.2 nvme (gen4) Crucial p5? 1x 1tb, and 2x 2tb. os ssd installed on motherboard, the other 2 on the pcie card (used for vm and docker containers)
am i missing anything? any improvements?
Will try use ipmi to set it up. hope that works since it’s my first time
will install the 10gtek sfp+ pcie card into the x16 slot. (for 10g om3 fiber optic networking)
Then for the x4 pcie slot, install the m.2 nvme ssd pcie card to be able to install 2 nvme ssd gen4
if the rails is a no go (still checking with seller), i can rely on my existing rack shelf already installed.
plan b.
ecc be damned, just get a 5600g cpu, B550 PG Riptide motherboard (supports 6 sata ports)
https://pg.asrock.com/mb/AMD/B550%20PG%20Riptide/index.us.asp
Umm.
No.
The 2 M.2 card you linked before only has one PCIe NVMe slot. The other is a SATA SLOT which is just used to convert a SATA port on the mother board into a M.2 SATA slot.

well im gonna need 3x m.2 nvme ssds somehow not quite clear how to do that. i thought just adding pcie card for it would work but…
well if the leo doesnt cut it i can go plan b?
server B550 motherboard + his 5600X
OK, no GPU needed, 6 SATA, 4 M.2 in x16 slot (DDR4 ECC UDIMM possible)
problem with this though.
if i use the x16 slot for the m.2 ssds
i cannot install my 10gtek which requires either a x8 or x16 slot to install. It wont work in x4
You need to figure out which sockets and bifurcate, and what the lowest they can bifurcate to is.
Without fancy pcie switches, you can only get one NVMe in a PCIe x4 slot.
If the 16x can bifurcate to 4x4x4x4 then you can get 4x M2s in that slot.
But if it can only go to 8x4x4 then you can only get 3 M2s, or 2 M2s and a someother card, such as a GPU.

sounds like i need a mobo with 2 x16 pcie slots at least then or a 1x 16, and x8
im guessing here. no expert this is why i wanted to copy someone elses build cauz then i know that works.

what about this asrock X570 Pro4? has 8 sata ports. so if like u said the pcie card converts to m.2 nvme, wouldnt this enough to leave 4 sata ports for my hdds?
2 PCIe 4.0 x16, 2 PCIe 4.0 x1
8 SATA3, 1 Hyper M.2 (PCIe Gen4 x4 & SATA3), 1 Hyper M.2 (PCIe Gen4 x4)
https://www.reddit.com/r/HomeServer/comments/1c5gcbq/asrock_x570m_pro4/
So my AsRock X570M Pro4 can bifurcate the 2nd x16 PCIe 4.0 slot into x4/x4/x4/x4, (or x8/x8, but that’s not useful to me) for example for using the quadruple NVME cards that are available on the market, but isn’t the uplink to the CPU from the chipset only x4 anyway?
So even if I RAIDed four NVME on the second slot I’d be limited to x4 speed because of the weak chipset uplink?
Also why is the second slot even marketed as a full speed PCIe 4.0 slot if it’s choked by the chipset to CPU uplink to begin with? Wouldn’t a graphics card in that slot only operate on x4 real bandwith?
AK-Brian
The X570M Pro4 supports bifurcation of the primary (x16) slot, reconfiguring it into an x4/x4/x4/x4 arrangement. A few folks on the NAS forums have been using the quad-M.2 cards on this board without issue, either with the GPU in the x4 slot or running headless.
That said, I cannot think of a practical use case for allowing bifurcation on the x4 chipset-connected slot on the X570M, since it’s already just four lanes, and my gut tells me it’s simply a BIOS option that ASRock has retained which is present across all of their X570 series products - it’s for a slot that doesn’t exist on certain boards. Many ATX sized X570 boards have two CPU-connected slots, which can be configured in a few different ways, but the second CPU-connected slot is not present on the Pro4 line.
If your goal is just to use a third NVMe M.2 drive, I’d grab one of the <$10 PCI Express x4 to NVMe M.2 adapter cards. This will get you Gen3 speed (up to ~4GB/s), and while it does share bandwidth with the rest of the chipset-connected traffic, the CPU-PCH uplink on X570 is actually 8GB/s in aggregate and traffic is switched internally at the chipset. The Toshiba RC500 you mentioned only uses up to 1.7GB/s. It won’t be an issue.

I don’t know how importan power consumption is for you but the combination of X570, Asrock and AM4 is a really bad combination.
X570 is a power hungry shipset. My 5700x with a X570 idles at 30 watts. With a B550 it’s at 18.
AM4 has a high base idle power draw.
Asrock doesn’t support higher C states through the BIOS and you can’t enable ASPM.
