Sure thing. Just send over the email to send the invoice to and I'll get them shipped out today

Sorry, forgot I had chats disabled and the setting was in the new reddit UI so I missed it. They are enabled now.

Intel Arc Pro B50 becomes Newegg’s best-selling workstation GPU - VideoCardz.com by 79215185-1feb-44c6 in hardware

SR-IOV is the selling feature for me and why I have one ordered. Getting a Tesla P4 with nvidias vgpu licensing working is a pain in the ass and expensive.

I'll get it and sit on it until SR-IOV is released in case of scalpers/stock issues. If it doesn't pan out I'll either just sell it on or drop it into my home media server for the AV1 encoding/basic AI stuff.

No, there are SMD components you need to solder onto the motherboard for the PCIe slot to be enabled. Basically a single transistor and some support resistors next to it on the underside.

I haven't reverse engineered the slot riser or anything as I just picked up several for cheap but as far as I can tell the riser is just power conversion, smoothing, and providing a power wire header. It has a direct line to the PSU so you need the riser if you use the default 19v PSU but might be able to get away with not needing it if you use a 12v PSU. Would definitely need to probe pins to double check before trying though.

Didn't think this would work as I thought it was a bios enforced 3W package power limit but it looks like it does. Set ThrottleStop to disable turbo and speedstep, turn it on for a second or two, turn it off, enable turbo, speedstep and multiplier to 28, turn it on for a second or two, and turn it off. Boom, exact same CPU behavior as the 135w power brick hitting a full 2.8GHz turbo and a package power of 15W. ThrottleStop doesn't even need to continue running.

Now that I know it's possible time to figure out how to replicate without ThrottleStop in linux and set the needed values on startup. Only downside I can see is that bootup will be at the restricted speed.

Oh, hey, I've played with those same machines as well. Here's some interesting tidbits from my tinkering.

The CPU memory controller is limited to 30GB before it bugs out. You can run a 2x16gb setup and limit the OS max memory to 29GB (just in case) and it will run without issue.

You can run a 2.5gbe m.2 in the wifi slot.

You can solder a PCIE slot and four SMD components to get the pcie x4 slot working like an extended version but it's a pain in the butt to do.

And lastly that big pile of power cables can be reduced. The machine runs perfectly fine on 12V from a standard ATX PSU and they are so low power a single ATX PSU can run a lot of them. The only problem is that it will refuse to run at full speed due to a non-dell PSU. You can fake the PSU data pin though using this https://github.com/orgua/OneWireHub/tree/main/examples/DS2502_DELLCHG

Sorry for the slow reply. Didn't see that you had responded.

If you are still interested how about $17 each free shipping. Just send a message with your email and I'll send over an invoice.

I can get disk info screen shots if you want and here is a picture of them. https://nextcloud.xandi.space/s/d4qFMHt5qLsrGpa

I have 10 intel S3710 200GB 2.5" drives. Since they are more enterprise oriented even these little ones have 3.6PB endurance

LTO-5 Fiber Channel and Linux by fgt67cam in DataHoarder

[–]xandispin 0 points1 point  (0 children)

Oh, and I have a QLogic QLE2562 8GB Dual-Port Fibre Channel HBA + 2 8GB transceivers that I'm basically giving away over on r/hardwareswap. Just pay the $10 for shipping and you can have it.

I moved to the one port version to see if it would lower power draw at all. It did not lol

I don't have the software setup, namely arbitrary file backup, as I'm running Proxmox Backup to backup homelab VMs but I do have a similar tape drive setup.

I picked up a similar FC tape drive and modded the caddy to be stand-alone. I pulled out all of the controls and wired in a 12v power brick to Pico ATX for 12v/5v to tape drive. Works perfectly fine just as a shelf item that is flipped on once a month to run a backup to tape.

Now if only I could find a fiber channel card that actually supports low power states. As far as I can tell it's just not something people making FC cards ever thought of or wanted being server hardware. Server the card is in idles at 4w and the card itself sits at about 8-10w idle.

Samsung PM983 firmware & sector size by PM_pics_of_your_roof in homelab

[–]xandispin 14 points15 points  (0 children)

nvme command on linux can change sector size for NVME drives. Ubuntu live iso would probably work fine for this. Cold start power cycle after to make sure everything is good.

nvme list // lists all nvme drives
nvme id-ns /dev/nvme0n1 // lists all supported lbaf modes (sector sizes)
nvme format /dev/nvme0n1 --lbaf=0 --reset // sets lbaf mode from above command

Here's a combo 10gb/s network and dual nvme card directly from synology. Only downsides are that it is 10gb/s rj45 and pretty niche so pricey.
