Thanks, I'll need to have a look at how the chipset link works, and how the southbridge combines incoming PCIe lanes to reduce the number of connections from 24 in my example, to the 4 available. Despite this though, and considering these devices are typically PCIe 3.0, operating at the maximum spec, they could swamp the link with 3x the data it has bandwidth for (24x3.0 is 23.64GB/s, vs 4x4.0 being 7.88GB/s).

This is what I do as well. I have a public DNS record for my internal reverse proxy IP (no need to expose my public IP and associate it with my domain). I let NPM reach out to the DNS provider to complete verification challenge using an account token, NPM can then get a valid cert from Let’s Encrypt and nothing is exposed. All inbound traffic on 80/443 remains blocked as normal.

The icing on the cake for me is the empty “Neat Patch” above the switches

Thanks. This is a pretty compelling option. I hadn’t looked at the entry level arc, but when it comes to encode/decode it seems all the tiers are similar. 30W is okay, and it’s not a hard limit or anything, just nice to keep bills down!

I hadn’t considered AMD, really only due to the high praise I’m seeing around the web for QuickSync, and AMD falling behind both Intel and nvidia in hwaccel. Certainly will consider if there’s not a viable option with QS anyway.

And you’re right, the south bridge provides additional PCIe connectivity (AMD and Intel), but bandwidth has to be considered. Connecting a HBA (x8), 2x m.2 SSD (x8), and 10Gb NIC (x8) over the same x4 link for something like a TrueNAS VM (ignoring other VM IO requirements), you’re going to be hitting the NIC and HBA and/or SSD (think ZFS cache/logging) at max simultaneously, saturating the link resulting in a significant bottleneck, no?

Thanks. I'll be the first to admit a lack of knowledge with respect to CPU architecture - very interesting. I think you've answered my question - I can't have QuickSync AND lanes.

Given I can't have both, I suppose the question pivots to a comparison of performance-per-watt and number of simultaneous streams of an iGPU with QuickSync vs. a discrete GPU (likely either nVidia or Intel ARC), considering a dGPU will increase power usage by 200W+ under load (27c/kWh here). Strong chance I am mistaken though, and have misunderstood QuickSync's impressive capabilities. I will keep reading.

I think the additional lanes are of greater value for future proofing. I can just lean on CPU without HWaccel. Thanks again!

 

I'm currently running a Xeon E3-1231v3. It's getting long in the tooth, supports only 32GB RAM, and has only 16 PCIe lanes. I've been butting up against the platform limitations for a couple of years now, and I'm ready to upgrade. I've been running this system for ~10yrs now.

I'm hoping to future proof the next system to also last 8-10 years (where reasonable, considering advancements in tech and improvements in efficiency), but I'm hitting a wall finding CPU candidates.

In a perfect world, I'd like an Intel with iGPU for QuickSync (HWaccel for Frigate/Immich/Jellyfin), AND I would like the 40+ PCIe lanes that the Intel Xeon Scalable CPUs offer.

With only my minimum required PCIe devices I've surpassed the 20 lanes available on desktop CPU's with an iGPU:

  • Dual m.2 for Proxmox ZFS mirror (guest storage) - in addition to boot drive (8 lanes)
  • LSI HBA (8 lanes)
  • Dual SFP+ NIC (8 lanes)

Future proofing:

High priority

  • Dedicated GPU (16 lanes)

Low priority

  • Additional dual m.2 expansion (8 lanes)
  • USB expansions for simplified device passthrough (Coral TPU, Zigbee/Zwave for Home Aassistant, etc) (4 lanes per card) - this assumes the motherboard comes with at least 4-ports
  • Coral TPU PCIe (4 lanes?)

Is there anything that fulfills both requirements? Am I being unreasonable or overthinking it? Is there a solution that adds GPU hardware acceleration to the Xeon Silver line without significantly increasing power draw?

Thanks!

I use the Amplipi from Micro-Nova for whole-home audio and I love it. It’s local, open source and has a Home Assistant integration.

The main unit has 6 zones, but expansions units can be added. I think it supports up to 4 simultaneous streams. We use 2x AirPlay streams, and a turn table connected via RCA, but many other options are supported. They detail it all on their website and GitHub repo.

Yeah they must have removed the fields in 23.10. Thanks again

Thanks for the clue. I haven't been able to find anything in my config. Is there supposed to be a text field for setting auxiliary parameters, or are we just referring to advanced options here? Do they need to be configured via the shell in Scale? I've included screenshots of my SMB/share config below.

Next step will be to just install Scale fresh and re-config from scratch, importing the existing pool. This will hopefully eliminate any odd parameters that shouldn't have been carried over from BSD.

Also, and I'm just venting now, why isn't any of this mentioned in the Truenas article for the migration, or the supplemental "Preparing to Migrate..." article...?

Hey all, not a lot of activity here yet, but hopefully someone can offer some advice!

I'm having major regrets following migration from Core to Scale. The migration via update file went smoothly, but immediately apparent on starting up Scale, all of my SMB shares were broken. Both Linux and Windows clients are unable to connect.

I have since tried creating new users/groups (I noticed that my normal user and group with id's 1000 had been changed to 1001 in Scale), stripping ACL's and recreating, and deleting the shares and recreating. Failure to connect on each attempt.

Is there something I'm missing relating to the migration that prevents SMB from working? I'm not well versed in the inner working, or shell command available for troubleshooting, so most of this has been attempted through the GUI.

Also, I realise I have shot myself in the foot. Like an idiot, I saw the feature flag update message when Scale first started. I clicked through and upgraded without even thinking. I realised what I had done when I restored my Core VM from the previous day - the pool was offline, with zpool import showing an unsupported feature message. So any path back to Core is off the cards I think.

Any help is appreciated...

EDIT:

I think I have found the culprit. I downloaded the debug info and had a look at the SMB config (specifically net_config.txt). For some bizarre reason, the SMB interface had bound to an old IP address (two or three home network revisions ago - not used in many years).

[GLOBAL]

interfaces = 127.0.0.1 192.168.0.200

By selecting the systems current IP address in the optional "Bind IP Addresses" field in the global SMB service settings (under advanced), I've been able to rebind it to the correct address, and I have access (tested in Linux only so far)! phew...
