You can fit a lot of NVMe. I think all these mods work on an M720q as well: https://www.reddit.com/r/homelab/comments/1ddkzjaHas someone managed to get both 4 disks in an external inclosure and the dual sfp+ NIC into a M720q?

It requires soldering a modification GitHub - badger707/m920q-pcie-bifurcation: Lenovo M920Q PCIe x8 bifuration to x4x4The M920q doesn't support bifurcation which would be necessary if I wanted to connect to two NVMe x4 SSDs. Would it support a quad 2.5G PCIe x4 NIC, though, where each Ethernet controller chip is wired to a different PCIe lane?
I've seen conflicting information on whether bifurcation is or isn't needed and I'm hoping someone who has practical experience with this can report on their findings.
Thanks, I will save that link for future use.It requires soldering a modification GitHub - badger707/m920q-pcie-bifurcation: Lenovo M920Q PCIe x8 bifuration to x4x4
Looking at the schematics of the M920Q, there is a possibility to control a second fan. The connections are not brought out on the PCB but there are 2 test points for HDD_FAN_PWM_SIO and HDD_FAN_TACH_SIO.Are there now way to get speed control/PMW/RMP monitoring on the second fan that will work with linux?
Unfortunately Intel removed the ability to bifurcate the CPU lanes to x8x4x4 on 12th, 13th and 14th generation, so it's not possible to bifurcate the riser slot on Tinies based on those generations. The most you could get on those machines is the x8 CPU link and the x4 PCH link. In theory on the latest Core Ultra 200 based models it should be possible again, once someone figures out the new soft-strap based bifurcation config.I'd like a Lenovo Tiny with a relatively newer CPU (Intel 12th Gen would be great - looks like M90Q Gen3 would fit the bill) but I'd like to mod it to be able to use all of the PCIe lanes. I'm wondering if there are any newer tinys that are known to have pbie bifurcation mods with compatible risers?
It looks like the tiny6 has one GitHub - qq8322302/Tiny6-P340-pcie-bifurcation-expansion-card: Lenovo Tiny6 P340 PCIE Bifurcation Expansion Card but I'd prefer12th Gen (want the newer integrated graphics with SR-IOV to share the device in proxmox)
Thanks.
Thank you for the information. I did not know that. What a shame. Especially since there's a big leap in IGP performance from 10th to 11th gen, but for some reason 11th gen (rocket lake) has neither SR-IOV or GTV-g.Unfortunately Intel removed the ability to bifurcate the CPU lanes to x8x4x4 on 12th, 13th and 14th generation...
I've been looking into riser slot bifurcation possibilities on all generations, and on Tiny7 (M90q gen 2/P350) it isn't possible either, since the bottom side NVMe slots are actually connected to the CPU lanes (for PCIe 4.0 support), meaning it's already using x8x4x4 bifurcation with the x8 going to the riser slot and the x4x4 going to the NVMe slots. The newest generation that you could get bifurcation on right now would be Tiny6, until someone figures out TIny11.Thank you for the information. I did not know that. What a shame.

Oddly, tiger lake (11th gen mobile) has SR-IOV. Come on, Intel.
I was hoping to have the IGP run double-duty between jellyfin encodes (VAAPI) and immich facial detection (OpenVINO). Without SR-IOV or GTV-g I guess that means I would have to run them as LXCs (or privileged dockers) with /dev/dri mounted?
Are there any reported successes and/or instructions for Tiny7 (M90q Gen2, Core Gen 10/11) bifurcation mods out there?
