Yes, some chips (or rather parts of all chips) are spare on enterprise SSDs. You can even see how much is left via smart data

The loss did occur on simple ping commands, only on 2 out of 5 ports. The vendor confirmed the behavior to be faulty and took the switch back.

Maybe it was just a faulty model? However I do use multicast in my network (corosync) and a lot of 10G switches seem to have problems with that, maybe this was the case here, too.

The exact model is TRENDnet 5-Port 10G Switch, 5 x 10G RJ-45-Ports and there sure seem to be quite some people having issues as well...

I tried a 5port 10g trendnet switch some time ago, had weird speed issues and package losses. No good experience at all :(

In my area there is a dog which has been fed a vegan diet for almost ten years now. So they definitely can survive on it. Said is healthy.

Those 28 people sent back are conflicted felons. All of them committed serious crimes (Schwerverbrechen)

Nice downvotes on your post. Must be really nice people who find it okay to lock a little kid into a small room. One can only hope they never have kids themselves.

It might be cheaper but that is a pure capitalistic point of view. And capitalism is what brought us to our worlds current state

But how can one consider natural gas? The whole point is to avoid getting more greenhouse gases into the atmosphere?!

What is your understanding based on?

Regarding production batteries might be more expensive, but they can be charged some thousand times without any additional cost

Because canonical removed packages from apt to prevent users to install their apps from apt instead. Firefox for example.

Firefox from Apt is a link to a snap!

https://askubuntu.com/questions/1399383/how-to-install-firefox-as-a-traditional-deb-package-without-snap-in-ubuntu-22

This is some bullshit level activity that I do not want.

I moved away from Microsoft to not have to deal with such an annoyance. Now canonical is doing it to their users.

Avoiding snaps on Ubuntu sadly is not an option anymore. Maybe go for pop!_os Instead of Ubuntu.

There are already some charging stations in Germany offering 400kW. Still 16 minutes though. 800kW is just insane. CCS is currently capped at 500kW, so you would need MCS which is planned for trucks.

Hi,

I've got a network setup consisting of 3 proxmox servers of which two have a 10Gbe interface. All interfaces are RJ45 copper ports.

So far I've got two qnap switches with 2 10Gbe and 5 2.5Gbe portss. They are connected to each other via one of the 10Gbe ports, and one of the servers on the other one.

This setup is working flawlessly, iperf measurements show 9.4gbit/s in both directions.

Recently I tried to increase my network for future expansion and bought a trendnet switch with 5 10Gbe ports.

Weird problems occurred and as they were also described in some amazon reviews I returned the switch and bought another one, this time a 4port 10Gbe switch from ubiquity.

Again there are problems. This time one direction seems to be at 10gbit/s as expected while the other direction (between the same two servers) is limited to 1gbit/s. The connection to the third server shows the same problem (one direction 2.5gbit/s and the other one limited to 1gbit/s).

All wires are connected correctly and as there is no problem on the qnap switches I do believe that there is no hardware problem on the cable/NIC side.

However I'm not sure if this is this just bad luck or some deep network problem I don't understand.

Maybe someone has an idea?
