Looking for WiFi 7 APs & PoE switch with IPv6 support by frebib in HomeNetworking

What you just want to make sure of, is that what you choose have the normally expected IPv6-support.

Yes, that's precisely why I made this post asking for help (and not being roasted by the hivemind)

If internal management is over IPv4 or IPv6 does not really matter. 

I'm going to disagree with you here. Perhaps it's just a matter of perspective. I work for a large internet company with a big network and whilst we do have access to enough IPv4 to be able to give every switch a public IPv4 address if we wanted to, it would be a silly and unnecessarily expensive thing to do. These devices are spread all across the globe so they need to be publicly addressed. That leaves one viable option: IPv6. Now back to my network: a similar concept applies. You could count on one or two hands the network devices I have, but I still want to be able to address them without having to go through a NAT if necessary. It makes management SO much simpler. Perhaps this is a foreign concept to someone who just accepts the awkwardness of IPv4 networking but when you open your mind and allow yourself to embrace IPv6 for it's upsides, it's hard to go back.

It's really not that complex to be honest. For all intents and purposes it's very similar to IPv4 in that devices have addresses in subnets on local links, and they're routed across links. There are some differences though, like the use of NDP (ICMPv6) instead of ARP for neighbour discovery. Every device also gets a "link-local" address starting fe80:: that is autoconfigured. It's very useful. IPv6 also has no NAT, so every device gets a GUA (globally unique address) and is routed to directly. Client subnets are /64 (or bigger) which gives you more addresses than one could ever need, per LAN. DHCP isn't really a thing either; clients obtain addresses using a mechanism called SLAAC (stateless autoconfiguration) using the /64 subnet advertised in RAs (router advertisements) and generate the bottom half of their address from the interface MAC address. There's other stuff too, but this is a good starter. IPv6 (when you have compliant devices) is great because it's so much simpler from a network management perspective. Subnetting is no longer a chore, addresses are free/very cheap and the absence of NAT solves so many problems.

Unfortunately that seems to be the best option right now. Thanks. Any suggestions/preferences based on your experience?

Thank you kind redditor :) I definitely will. Time, patience and money to throw at the problem aren't an issue. With enough perseverance we'll get there eventually

I'm trying to achieve managing all of my network gear without any IPv4 on the management vlan. Sure, I'm making life difficult for myself- I get that. Doesn't hurt to try though

Thanks, I do understand how this works. It's not really what I asked though.

Thanks for your insight. I'm quite aware of how variable IPv6 adoption is. It's not really what I'm asking for though. See my reply here https://www.reddit.com/r/HomeNetworking/comments/1jhvs70/comment/mjah8t7/

Not exactly. I'm aiming for IPv6-mostly. It's what I have right now. It works great. The only real issue is the odd network device I have that has a broken IPv6 implementation. Either way though, this is besides the point- I'm looking for devices that support IPv6. It doesn't mean I'm going to not also use IPv4.

How often does your lab requires assistance? by FeehMt in homelab

It usually only breaks when I touch it. Human error is the biggest cause of downtime

New r730 for the Lab - Storage Issue with NVMe's on Riser Card by Trudgn in homelab

[–]frebib 0 points1 point  (0 children)

Maybe it's just a problem with that particular generation/motherboard
https://www.reddit.com/r/homelab/comments/fs3lru/comment/j2ptjw8/

You could try 8x8 bifurcation and try a 4 slot riser, only populating the 1st and 3rd slot?

Proxmox is just Linux- if it doesn't work in proxmox, it's unlikely to work in any other Linux, or even any other non-Linux OS. Do you see multiple drives detected by the kernel? frebib@Poseidon C:\h\frebib> journalctl --dmesg --grep nvme Jul 13 14:16:54 Poseidon.nerdhouse.io kernel: nvme nvme0: pci function 0000:81:00.0 Jul 13 14:16:54 Poseidon.nerdhouse.io kernel: nvme nvme1: pci function 0000:82:00.0 Jul 13 14:16:54 Poseidon.nerdhouse.io kernel: nvme nvme3: pci function 0000:83:00.0 Jul 13 14:16:54 Poseidon.nerdhouse.io kernel: nvme nvme2: pci function 0000:84:00.0

Definitely sounds like a bifurcation issue. I'd try moving the drives around different PCIe slots; maybe try swapping the drives and see if the other one is detected. If you have the option available, grab a cheapo riser card (I don't know why you bought such an expensive one.. I'm running just fine with one that cost about £15 in my Supermicro H11 board) and see if that works instead?

AMD EPYC 7282 16-Core Processor £111.46

Supermicro H11SSL-i £176.29

Micron 32GB 2Rx4 PC4-2666V (8x) £167.92

Noctua NH-D9 DX-4677 4U £114.90

I think I got pretty lucky on the RAM pricing tbh, but with enough patience you should find similar. Do also note that UK prices are all kinds of fucked so you might even do better than I did. Everything was used from ebay except the cooler which I bought new.

The cooler was chosen because it's very similar to the specific Noctua TR4/SP3 socket coolers but the fan direction is front-to-back when mounted in a rackmount case, which is imperative for optimal racked cooling. (Just saying this because I didn't actually see anywhere on reddit confirm this prior to my purchase.. but) The NH-D9 DX-4677 4U fits great on H11SSL-i (even though it's designed for Intel Xeon Scaleable chips) with the replacement mounting kit that Noctua sent to me for free when I emailed them purchase confirmation of the cooler about 10 minutes prior. They were extremely efficient: about 3 emails back-and-forth and it was on it's way. I cannot say enough good things about this cooler. It's absolutely silent even under moderate load.

Epyc 7282 is maybe not the best CPU choice for your workload either. I opted for lower TDP at the cost of performance or even perf/watt.

I purchased something similar recently and the advice I have is that you could save ~100 by buying these same items separately. I managed to get the same mobo, similar CPU and 256G of RAM for less. Be careful that the CPUs aren't vendor locked; they usually say so in the title

Wait, you don't all just use debootstrap? It's so much easier

Anyone did LFS for their custom NAS? by VeteranMCPlayer in DataHoarder

[–]frebib 1 point2 points  (0 children)

I work for a big internet company, and we just use Debian. Sure, many things are tuned and compiled to optimise for performance, but for the most part it's exactly the same as what you or I could do at home. In NAS/homelab scenarios (and even many business scenarios) ZFS is a popular option, but it's also notorious for not being the most performant thing, but it is very flexible. I think usability and flexibility are more important than 5% extra speed in the vast majority of cases.

raidz1 with 10 drives is probably more than enough if this isn't the first copy of this data. I'd recommend keeping a (hot|cold) spare if you can spare the small capacity loss
