I'm not using bifurcation. Not sure what the Genoa limit is, but apparently this is a known limit on the H13SSL-NT and other boards caused by the onboard VGA. Not sure what the limit will be after that because I'd rather not run a patched BIOS to see. Regardless switching to a 2P system will...

It's a POST error. I've been given a patched BIOS by a knowledgeable third party who says it's due to the built-in VGA stuff but I'm hesitant to apply it since you have to directly program the BIOS chip due to the third party's inability to sign the BIOS. Unfortunately Supermicro doesn't deal...

Oh well, I've ordered the GENOA2D24G-2L+ instead.

12 PCIe x16, got the error as soon as I added the 13th.

I should mention single processor boards like the H13SSL-NT have a limitation where it runs out of PCI resources after a certain number of PCIe devices are connected, so a dual processor board is necessary.

I currently have a few H13SSL-NT which are readily available from third party sellers, but need more PCIe in a single system. I can't seem to find anyone that sells the H13DSG-O-CPU-D without having to buy the entire chassis solution which I don't need. Any clue where I might be able to score...

Fantastic, that's awesome thank you!

I don't see anything in the Manual or BIOS screens about bifurcation support. Does anyone know if any or all 7 PCIE slots can be broken out as x4/x4/x4/x4?

The Broadcom PEX88000 PCIE 4 and Broadcom PEX9700 PCIE 3 family of chips have some very intriguing features, most interestingly Tunneled Windows Connection (TWC) that allows true multi-host to host communication via DMA. The previous generation PEX8700 only supported Non-Transparent Bridge...

The AMD v1000 series seems like the perfect system for a small form factor 1xM.2 2800 NVME + 1xSATA SSD/HDD Ceph OSD system. Connecting to an Infiniband backbone is paramount so a PCIE 3.0 x8 slot for QDR is a must have. Up to this point the best I've seen is PCIE 2.0 x8 outside of EPYC which...

Application is varied. multi-host without NT. Those things run less than $500 which to me is dirt cheap were it to work. $1k would be pushing it for an unknown part.

I've stumbled across IEI's SPXE-11S :: IEI which has 6 PCIe Gen3 ports attached to a PEX 8724. Even though this is a backplane part, I'm wondering if this could also be used standalone as a poor man's 6-port PCIe switch. Does anyone know if there would need to be firmware changes to be able to...

Unfortunately standards to affordable silicon let alone devices and software will be a long cycle. Definitely good to keep it mind for the stack. Thank you for pointing that out.

I have been running Mellanox QDR Infiniband primarily due to the magnitude of difference in latency using RDMA and its use via SRIOV in containers and VMs. Unfortunately Infiniband in the industry is almost entirely proprietary and PCIE fabrics have been a promising future for years now without...

Many years ago, probably a decade, I was looking closely at Untangle www.untangle.com. They touted the open source model and I considered contributing to their apps, but was leery of their license agreement which gave them ownership of all contributed work that they would then license back free...
