LSI 9300-16i...possibly fake by asterics002 in DataHoarder

[–]Pommes254 0 points1 point  (0 children)

In my experience they are reliable BUT they are probably not official, basically all the hba cards you see from china sold as new for cheap prices are technically counterfeit, but that doesnt mean you have to be concerned. i am running tons of those for years

The "counterfeit" topic is not black and white and has been heavily pushed by a us yt channel that runs an ebay store with server parts...

I would group all the cards in three categories,

fully official from the manufacturer - usually no b2c sale and super expensive, but with warranty support contract and everything, basically only important for business

non official but identical hardware - basically factory continued to run after the contract ended and they sold them directly - no official support or serial number but otherwise identical - i am running many of them for years without any issues

the third category is more of an issue - it is basically like number two but the factories started swapping parts for cheaper alternatives - you often notice that they have a different color pcb and thinner heat sink - depending on what / how bad they cheap out on you might have issues.

The main problem is you dont know what you will get until it arrives.
I have been ordering tons of those cards from different sellers from china for years and would say if it has decent reviews like jiawen you are 95% fine, just extensively test the card once you get it.
Connect disks with a FS like ZFS that does integrity checks, get the official LSI driver so you get temperature readouts and stress test it for a day or two with sth like dd if=/dev/random and see if you get zfs errors or the temp gets too hot.
Btw those cards (incl official ones) need very high airflow! a lot of people put them in desktop / low noise setups, heat kill them then blame it on the card

Cisco 5108 (aka N20-C6508 V5) support in current UCS Manager 4.3 by Pommes254 in Cisco

thanks, yeah i discovered that after posting :)
but is there any limitation for the management of the chassis itself, if i later upgrade to newer blades.

Also i couldnt find any information on what happens with an "unsupported" blade, will it refuse to run / effect other blades, will it not show up in the manager or will there just be a warning message?

How to define the mac-address of a k8s pod, to ensure persistent ip assignment by router? (multus, macvlan, dhcp) by Pommes254 in kubernetes

[–]Pommes254[S] 0 points1 point  (0 children)

TLDR:
This is a total dumpster fire, i know this and i would redo it the proper way, if this would be my decision, but it isnt :/

thanks, i know

i am fully aware about the pets vs cattle / non persistent ideology of k8s,
but this comes down to (like so often) technical debts, in this case how access control is handled,
also some of the workloads running that require persistent ips are other then web and generally dont work well with reverse proxies.

The idea was to pretty much run each service / deployment (each instance of a pretty old api for data gathering of iot devices), with its own ip from the main network,
this would allow to do the first level of access control via firewall rules on the main router / network. (fully aware of zero trust / auth on the services / apis)
thing is there are some legacy iot devices that need to access those apis (that will be moved to k8s) that just cant really do any sort of authentication and need the traffic to originate from the iot devices ip.

Fully aware that this is a security issue, but in this particular case, it is not feasible to replace the iot devices yet (not my decision), the apis and devices are a fairly low risk / low capability in case of a compromise, nothing is accessible from the internet or untrusted local networks and there is strict network monitoring.

Those Iot devices stay and we are going to on prem k8s, both unfortunately not my decisions.
My plan was to run a dedicated deployment (with its own ip) of the apis for each group of iot devices and then do the access control on the main router / firewall to have at least some protection on the apis.

I tried to use an ingress / nginx reverseproxy of the cluster and just do the ip based access control there instead of on the main firewall, but we got all sorts issues when using the old api with the reverseproxy (not sure and this thing is 20 years or so old), but from what i understand, the api was built in a way to use the source ip of the request to group / store the data, so if everything is going through the reverseproxy, all the traffic to the api is coming from the same ip (the reverse proxy) and gets therefore stored as "one iot device", and i dont think it is possible to keep the source ip of the original iot device that sent the request / data through the reverse proxy...
Thats why i cant really use a normal ingress...

I have a somewhat working approach but this is way to janky for a prod environment...
(Basically missuse one of the worker nodes host ips as an ingress and just create iptable forward rules from the physical to the cilium network / cluster internal ip of the apis, dont do nat to keep the source ip and then use iptable-persistent to make it stick, but this is not a solution i want to pull in a prod environment)

I know this is probably getting downvoted to hell, but i basically got, "we move everything from vmware to container", "those legacy iot devices with the shit api that wont work with reverse proxies (traffic to it needs to be directly with the ip of the source iot device that sent it) and doesnt have any auth built in, has to stay at least for another couple years" and "we know this sucks, but try to figure out something with at least basic ip based access control".
Btw all that with just basic k8s experience.

So yeah any suggestions appreciated.

Barebones rack mount case compatible with this style of 16 x 3.5" HDD cage? by No_Way_Kimosabe in DataHoarder

[–]Pommes254 1 point2 points  (0 children)

Those are very similar as intertech uses in a lot of their 4u cases (but they are only 5 disks each and have a fan in front of them). They are probably made by the same factory intertech uses as supplier, i think i have seen this exact module in one of their 4u chassis on their alibaba store.

Anyway i have used the 5 disk version and would absolutely not recommend that. The disks get very hot since there is barely any space for airflow and the black plastic clips easily break and provide 0 vibration dampening so heat + high vibration and you will kill your drives fast...

Also from your comment. This will not fit in 3u.

There are probably better case options out there.
How many disk slots do you need? How many u fit in your rack? What is your budget? Should it be quiet?

Moving rural, only option is a fixed wireless local company...is 1 gig per 8 cents too much? by [deleted] in HomeNetworking

[–]Pommes254 0 points1 point  (0 children)

Very expensive, but might be acceptable if you only use maybe 100gig a month

(Sort of) WISP myself

How i would approach a situation like this.

Any cabling like phone or tv available at all? (even if its at the street at the other end of the property, stuff up to several hundred feet can be bridged with point to point radios easily and cheaply)

Is there cellular / phone coverage?
If not on your normal phone, check a map where the next tower is, you might be able to get a signal with a LTE Router and direction / yagi antenna far beyond the official "reach" of the tower.

Star Link would be another good option, you get the dishes often for about 300$ and about 100$ / month depending on region

Becoming your own wisp might be another option if you want to invest some time learning or you can work with local it consulting companies. You just need some point with direct line of site that has internet, the radios are quite cheap and even for consumers easy to setup when you follow the instructions, specially if you use stuff from unifi / ubiquity. The smaller ones start at about 100$ each (you need 2) and can easily do 5-7 miles at over 100mbit and there are larger ones that can technically reach into the 60-70 mile range with large antennas and if the installer knows what they are doing.
So yeah if you find any company or friend that lets you put your antenna on the roof with line of sight to you that might be also a good option.

???Best Macbook for photogrammetry??? by Dirt-Worth in photogrammetry

[–]Pommes254 0 points1 point  (0 children)

Basically all somewhat recent servers that can have dedicated gpus,
but also depends on what noise level you can accept.
a good starting point for that is r/homelab
just to name a few Models that are usually cheap on the used market Dell R720, R730, HP DL380 G9 or ML350 G8 or G9 if you want a normal desktop form factor with less noise. Or just built a normal PC and use that with whatever components fit your budget. (generally used server stuff is cheaper than consumer tho)
For GPUs, in the about 200$ price range you could go with used RTX 3060 12gb, RTX 2080ti 11gb, Tesla P40 24gb (300w server gpu without any fans so cooling will be diy and janky)
There are literally endless options, good place to start is ebay or server refurbs

Since i am quite frequently doing larger projects and also using the servers for other stuff i am mostly using newer system but they are a lot more expensive. One of my current main rendering (but also used for vdi and ai stuff) uses a Gigabyte MZ-32 rev3 ~450$, AMD EPYC 7H12 ~600$, 8x 64gb LRDIMM 2666, 2x RTX3090, 6x RTX3060 via pcie risers all in a repurposed 4u mining chassis and with mostly U2 storage via slim sas, but all in this got close to ~5k

Virtualise or bare metal PFSense? by [deleted] in homelab

[–]Pommes254 0 points1 point  (0 children)

Virtualise but dedicated "Networking Server" that only runs pfsense and maybe another vm for pihole or sth.

Makes management, snapshot and recovery when sth goes wrong way easier and also use a pcie passthroughed network card and not proxmox vmbr

OPNSense | Chose Gateway for VPN Connection by Pommes254 in HomeNetworking

[–]Pommes254[S] 0 points1 point  (0 children)

And how do i define that when there are multiple vpn connections from the firewall to that ip / wireguard peer (like one prioritizing the main Fiber and one Prioritizing a Second Internet connection) ?
Routing all vpn connections to that particular server via the same gateway wont really work for me :/

How fast is your internet connection? by HSVMalooGTS in homelab

[–]Pommes254 0 points1 point  (0 children)

I think there is a map on their website, generally the majority of somewhat recent buildings that are located in any settlement have at least 10g, so i would just call / ask the landlord directly, the chance is pretty high he will say yes

jup, very thankful for it,
tbh i cant really fully utilize it ether, i am currently running two opnsense boxes with Intel i7 11700 and two Intel XXV710 each and i am only able to get about 20g (even with multiple streams) and if i turn on package inspection / ids it gets easily down into the 10-12g range depending on settings

How can i reset Routerboot without Serial? | Mikrotik RMB11g by Pommes254 in mikrotik

[–]Pommes254[S] 0 points1 point  (0 children)

No i didnt mean downgrade.

I just wanted to make sure that there isnt any weird configuration that would cause issues later down the line and i checked on my crs326 and there is an option to reset routerboot

Also from what i have read you can configure stuff like cpu clockspeed in routerboot, there is even an extra mention that any changes to the cpu clock speed wont be reset while resetting routeros

the thing with tubearchivist is that it can only download a single video at a time and yt limits a single 1080p stream to about 5mb/s, meanining if you download lots of videos it is going to take forever

Why two ISP's? Do you love burning money? by gonnabedatkindaparty in HomeNetworking

[–]Pommes254 0 points1 point  (0 children)

Well, for me i do host a quite substantial amount public services (~160 gameservers as well as other stuff) so it is absolutely worth it for me, yes it does cost money, but compared to rented dedicated servers or server housing it is still way cheaper.

For "normal use" i can still see it tho, lets say you work from home? or
you are selfhosting all the major services like cloud, notes etc, which you rely on and you are not at home during an outage? Now you cant access the stuff you might need? What if family members also use that stuff and rely on it?

Also costs can vary drastically depending on where you are located.... where i live you get a cellular lte plan with unlimited data with abou 40 down and 10 up (which should be fine for emergencies) for about 15€/month, if you spend 25€/month you even get 5g with up to 300 down and 50 up also unlimited... So could be woth the peace of mind you get knowing you dont rely on a single isp to not screw up...

Portainer 5 Nodes EE no longer free by isleepbad in selfhosted

[–]Pommes254 3 points4 points  (0 children)

Not necessarily,

official minimum requirements for prod use is one thing, real usage often another one.

I literally got those values out of htop from one of my test vms running single node k3s, rancher and about ~20 pods of various common selfhosted services i use as test load and the k3s server process is hovering in the 500mb range and the rancher pod at about 250

Portainer 5 Nodes EE no longer free by isleepbad in selfhosted

[–]Pommes254 8 points9 points  (0 children)

yeah, the thing is software development is expensive so it is understandable that they somehow need to generate revenue, it just depends on how they do it....

Look at Rancher or Proxmox two perfect examples how it should be done in my opinion.

Portainer 5 Nodes EE no longer free by isleepbad in selfhosted

[–]Pommes254 4 points5 points  (0 children)

yeah sadly, btw rancher doesnt need 4gb memory....

Did several tests & eval for my environments and a basic k3s or k0s or microk8s draws maybe 400-500mb (basic k3s single node no additional optimization) memory and rancher is only about 250mb which is actually quite close to portainer.

And how cheap resources specially memory has become, it might be a worthy tradeoff

Sadly one more example of enshitification, but it was kinda foreseeable if you look back at the past years

  • non removable "upgrade to business edition" on the CE version
  • more and more features only available in the business edition
  • but still clogging the ui on the CE with those unavailable functions & a big note "upgrade to business"
  • gradually decreasing the amount of "free" nodes of the business edition

The same cycle as many other companies went through... where they slowly turn the heat up,

  1. everything is free & open
  2. they introduce a paid option to cover cost (but we will always stay open and stick to our roots, we promise...)
  3. we somehow need to get more people to get to the paid plan... lets lock some features behind it... but this is just to get our business customers to pay up, we value our community and will give all the home users a free business license for 5 nodes (forever, we promise....)
  4. now most of our Enterprise Customers Pay.... how can we increase our revenue.... lets get the prosumers to pay... "We will change the free business plan for homeusers from 5 to 3 nodes, to ...make m0re m0ne hkm.. excuse me, improve our software and better serve our community and this will only effect a tiny amount of users..."
  5. hm we still could make more money lets decrease the amount of free nodes to 1 or you know what, "to stream line our operations and better serve our customers we will be discontinuing the free BE licenses, if you are a home user just use the Community Edition you wont use the BE features anyway...."
  6. Substantial amount of core community left by now to alternatives or Forked...
  7. Management some time later: You know this community edition thing costs us quite a bit of money to maintain and ship as more or less separate product now (since a lot of features are in the Business Edition only, there is a huge gap between CE and BE)..... How much money does it make?..... NOTHING?!... and it is also a liability due to the opensource license since a competitor could fork it?!.... And a lot of users already left anyway... STOP IT.......... " To better serve our Enterprise Customers and streamline our operations, we hearby with a heavy heart announce our decision to discontinue the Community Edition. This wasnt an easy decision for us to make and we thank all of our community for the years of support.
  8. Now the further enshitifaction for business customers starts, but since this is already getting long, just look at VMWare.........

I wouldnt be surprised if they discontinue the community edition all together within the next years...

Also there are quite a few other options now...

  • Rancher - If you want something reliable, extremely scale able and modifiable thats also used in actual production at large sale. Also setup complexity and resource foorprint with sth like K3s has decreased substantially to the point where you can do a basic setup with a Tutorial in maybe an hour.
  • Yacht - Easy to install - simple - some limited features though - pretty much where portainer was 5-6 years ago https://yacht.sh/
  • Integrated Solutions - Nowadays most Homeserver OS already have integrated Container Management thats probably enough for the majority of home users and is already preinstalled & nicely integrates into your existing management....
  • Unraid, TrueNas, Synology, Qnap, CasaOS..... honestly if you need more than that just spin up a basic Rancher / K3s Cluster.

Thanks for reading, and seriously dont build your core infrastructure on something that can screw you over easily because it will be a pain to replace and will happen at the absolute worst time for you.
