    Thoughts on T-Mobile 5G Internet?

    I have it on 5G using the n41 band mostly. It's ok. My local towers aren't too congested, so I don't get hit with the deprioritization too badly. What I do have is occasional times of high packet loss for no apparent reason. It will be basically unusable for a while. I have another connection I...

    Could ZFS copies=2 be the answer for this build?

    Even a good SSD is unlikely to keep up with 10Gbe. If you trust your backups and don't mind a little down time, there's nothing wrong with the idea. I don't know that I'd bother with copies=2 in that case though. You have checksums and verification, along with good backups. It doesn't hurt...

    Natex S5520HC BIOS recovery restores NICs

    Yeah, it's old school, but still plenty for the sort of things I ask it to do. I have a pair of x5675s in it, and plenty of RAM. Works well as a Proxmox host serving ZFS and a number of containers for various services. The array of rust likely pulls more power than the mobo/CPUs, and power...

    Clarifying IPv6 ULA

    Right, the address assigned from SLAAC should be stable with most even remotely modern gear. You can put them in DNS without issues. If you find a problem, you can static assign as well. The OS determines the details, like which method is used to generate addresses and if privacy addresses are...

    Clarifying IPv6 ULA

    What I did was to generate a ULA prefix using one of the many websites that do it for you. You want this so that your prefix is unique, at least that you have a high probability of it being unique anyway. This is nice so that you don't have collisions should you use a VPN or something else that...

    Home network IPv6 conundrum

    I don't know how much more "secure" the network is with a VPN. You're moving the point where someone has access to the unencrypted traffic, but it does help somewhat with stupid ISPs and such. There are VPN services that work with ipv6, so that's one option. I think I would set up a VPN only...

    General Home Server suggestions - Plex, HomeAssistant, Email with room to grow

    CPU, they will both work fine for what you are talking about. I'm not 100% up to date on video transcoding, but I'm sure you can find info on that. If you want to do things like hardware passthrough, Epyc and Threadripper are nice as you have more PCIe lanes so you don't lose performance with...

    New here.

    Shrug.. I still run 2 1366 systems. One is a firewall on OpnSense, one is my main storage/VM server. It gets the job done. They are power hungry, but so is the 10G switch, and the HDDs in the storage box use more than the CPUs. I will say that the single proc firewall can't saturate a 10G link...

    10 4tb hdds

    SATA expanders seem to have more issues than you would get with just a HBA. SAS expanders seem to work well for most people, but you can get a pair of HBAs for less than the cost of an expander, at least at the time I was looking. I would just get a pair of 8i HBAs unless you get a really good...

    Setting up routing between 2 different subnets - what are the basics?

    You will need to set up a route to it then. Another option is to give the server an interface on each VLAN. They can be virtual interfaces on the same physical interface. Exactly how you do that depends on the distro, Proxmox has a web UI that includes support for it. The traffic has to...

    Proxmox VE raid 1/ZFS?

    If there's no I/O, why have the Optane at all? :) IMO, the issue with consumer SSDs and ZFS is overblown. It does run them a bit harder, but it's not like they are going to die in a week. Even with the Optane as a cache, you still have to push data in/out of the SSDs. I wouldn't use the...

    Proxmox VE raid 1/ZFS?

    Sure you could. Either would likely work fine. I'm not sure how much you would gain with the Optane drive in either case though. A ZFS mirror is already quite fast on SSDs. To really benefit from a cache, you need that cache to be faster than the drives. It is, but how much? And you would...

    Setting up routing between 2 different subnets - what are the basics?

    I would, and did, separate them out with VLANs and use my OpnSense firewall to route between them, the little traffic I allow between them. My setup is pretty simple. Internal network. Reasonably secure/trusted devices that I want to generally allow to do most things. Main file server...

    Setting up routing between 2 different subnets - what are the basics?

    I think you might be missing some parts of how IP works. The stack compares the destination address to the netmask and local IP to see if it is on the same subnet. If it is not, it checks the routing table for a route to that subnet. This can be a specific route, or the default route. It sends...

    Setting up routing between 2 different subnets - what are the basics?

    Masquerade is NAT. You don't need it for this. Forget all the upper layer stuff for now, you need to get L3 working. Unless you are using L3 routing in the switch, you don't need to configure it for subnets. The subnets need to be isolated, either physically or with VLANs. It is possible to...
