If only these had a 10gig port on them instead of the 2x 1gbe.

Been offered the full servers at 80€/ea previously but did not look like any cheap way to get 10gbe onto them.

You could do adapter abortion level stuff with that m.2. It has 4 lanes of pcie.

Wow, mITX, ECC capable, (relatively) low TDP, and cheap?

Seems like this mobo comes out of these servers G431-MM0 and they don't have the PCI-e 16x slot (4x)
"MJ11-EC1 does NOT have the bifurcation option in the BIOS" from another forum.

just hidden, needs some input/acceptance/password ???

 

[Bjorn Smith]

tempted to pick one up for a firewall, probably faster than my C3338

do you think it can fit in a 1U chassis?

 

[monotux]

I accidentally bought one of these, plus ram. I’m fine with it being only gigabit and no pcie slot, as it’s mitx and has enough ports for my drives.

With the fan on top, no.

 

[efschu3]

To sad it has neither 5 sata, nor 8 pcie lanes, nor digital video output. With either one of these criterias it would be a nobrainer for me.

(Or would it be possible to solder another 4x pcie plug ?)

The slimSAS 8i connector in bottom of board is pci-e x8, its the link to the pci-e breakout board in the server.
In the other posts/threads on this boards ive seen people connect x8 or x4+x4 adapters to it, but those cost about same as the board itself.

There is a thread on here about this board - Gigabyte MJ11-EC1 EPYC 3151 Mystery
Some consumption data etc there

 

[efschu3]

So actual how many lanes are useable (with adapters)?

slimSAS 8x
M.2 4x
U.2 4x

Makes 16 in total, right?

 

[Cruzader]

i dont think ive seen the slimsas 4i connector confirmed/used, atleast not that i remember.

When i looked at adapters my idea was splitting the 8i to x4/x4 for nic+hba to do 8hdd ceph node and keep the m.2 for db/wal storage.
Halfway gut the server, put the 8x3.5" in rear of case and (if able to find cheaply) replace psus with 2 lower wattage units.

 

[efschu3]

So it makes 12 usable lanes?

its made for 1U, the FAN is custom, not required if your 1U chassis has the usual jet engine FANs.

The heatsink in picture with fan on top is the default/original heatsink for that board design.

such a crap from Gigabyte ? strange !

It was meant for industrial/automation/robotics products and their custom enclosures.

That they got put into stuff like the mining servers was more an afterthought as it needed almost no compute/lanes.

 

[efschu3]

I'm still confused about the usable pcie lanes amount. Is it 12 or 16?
