Any idea where I can find a P350 Tiny PCIe x16 riser (part #5C50W00877) for sensible money? The only place that seems to have them in stock is Aliexpress, and they're gouging the heck out of the price over there


The riser for the older P330 tinys seems relatively plentiful on eBay, but I've compared these to photos of the newer one and the older riser has fewer pins on the motherboard connector so it's unlikely to be compatible.

I refuse to pay £60 / $70 for a basic PCB that probably cost $2 to make.
I have a spare one i can sell you if you are in the UK, I ordered two from ebay as I thought I was going to get 2 p350 tinys but only ended up getting one

Genuine Lenovo ThinkStation P340 Tiny Workstation PCIE16 Riser Card 5C50W00877 | eBay you can always message these guys as well to see if they will be able to get more, I had to wait a good 3 weeks for it so assuming they order direct from lenovo.

I'll post the link later if I remember. It's not much different, but in the end, it worked for me
Ha, I remembered. Here is the documentation that I've followed and worked flawlessly. Instead of the USB Fling, I used the Network Community Fling
What I've done also is create a .ps1 file with the contents:
Code:
Add-EsxSoftwareDepot .\VMware-ESXi-7.0U3d-19482537-depot.zip
Add-EsxSoftwareDepot .\Net-Community-Driver_1.2.7.0-1vmw.700.1.0.15843807_19480755.zip

Yeah, it's a problem. I'm hoping this is a temporary issue relating to component shortages and it'll resolve itself during the northern summer.

If you think that's bad, the standard chassis screw (at the back, which you take out to access the internals) is a £25 spare part, which is why I added its size to the original post. It's a good move to replace it with a thumbscrew anyway.
Mad. I'll be extra careful not to lose that one then.

That would be helpful. How much are you asking, including standard UK postage?

I bought a pack of twenty M3.5 black metal thumbscrews for £3.50 delivered; I wouldn't worry about it. I do recommend you replace that screw with a thumbscrew anyway, since then the chassis is toolless and you can upgrade the RAM, add m.2 drives etc without hunting down a screwdriver.

But the high theoretical cost of the part did help me when an eBay seller sent me a Tiny without a chassis screw, and I said - well, see, it's £25 to replace, so they gave me a £25 discount...

The riser for the older P330 tinys seems relatively plentiful on eBay, but I've compared these to photos of the newer one and the older riser has fewer pins on the motherboard connector so it's unlikely to be compatible.

I refuse to pay £60 / $70 for a basic PCB that probably cost $2 to make.
I can confirm that the Tiny5 riser does not work with the Tiny6 chassis. It does fit, right down to the screw placement and where it puts the PCIE card, comparing with the Tiny6 PCIE x4 riser I got from encompass and a x4 single 10GbE NIC. But the box will not power on with the Tiny5 riser in it. I have a couple Tiny6 x16 risers on backorder from encompass with a currently expected ship date of 8/30. I hope they can hit that!!

In other P350 news, I'm slightly disappointed to see that this model idles a few watts higher than the M720qs I have in my cluster. Even with a single 10GbE NIC vs a double, it idles in Proxmox at 19-20w, vs 14-15w with the older boxes. I'm sure the bigger power supply plays some role, since at idle these things are floating around 10-12% load, which tends to be pretty inefficient for most power supplies. I also need to turn everything off in the BIOS though just to make sure. Of course, 17000+ passmark, 32gb of RAM, 10GbE, and space for 3 SSDs in a ~1L enclosure is pretty darn tough to beat.

@adman_c, Have you tried undervolting yet?
I have not. Do you have links/how tos you can share?

Oh, and @Parallax I can't remember if you already verified this, but the SATA connector on the P350 motherboard does indeed work just fine with the older models' SATA cables. Booting from a shucked 256gb SATA SSD as we speak in my tiny monster hypervisor.

I do run Proxmox on my Whitebox built from spare parts ;)
For now, I've settled with ESXi on them as it provides more learning value/skills development for work.

Nonetheless, a good suggestion I shall try in the future :D

I suspected but hadn't verified, so thank you. I'm going to test out a random "laptop" SATA cable/connector off eBay 'cos that's a cheaper way to do it and will post back. How are you securing your naked SSD?

Make sure the laptop SATA connector has the same number of pins. Several of the ones I looked at appeared to have a different number. My naked SSD is currently wrapped in electrical tape to prevent shorts and is wedged against the back of my NIC. Since these drives live their life in an enclosed plastic space I figured the electrical tape wouldn't make it cook but it's a good reminder that I should check the SMART data for temps just to verify.
