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 :(
Yeah, we pay a lot. We also got one of the lowest downtimes regarding electricity, on average approximately 10minutes per year…so that’s kind of a (small) advantage you get for the premium price
Average load 800W is 0.8kW24h30d=576kWh/M
Which is over 172€ on a 30ct/kWh contract.
Just my 2 cents:
Proxmox. Flexibility for both new services via VM/LXC and backups (just install proxmox backup server alongside and you get incremental backups with nice retention settings, file-restore capabilities as well as backup consistency checks)
If it’s in a VM/container you don’t need to worry about backups, see 1.
In this case isn’t it sufficient to be able to access the data via Windows network?
Yes,
It does not work. Additionally, the ubiquity switch does not sync with 10gbit/s to one of the qnap switches (I tested with different cables and ports, but the led on the qnap stays orange, indicating connection speed lower than 10gbit/s)
As I’m maybe returning the switch due to the problems I hesitate to register it to access settings. Jumbo frames settings could actually be the solution. But with the problem mentioned in the first paragraph I’m not sure. A 300€ device should just work IMHO…
Thanks for the suggestion with ping, I will test it.
Thanks for your input. All criteria you mentioned are met.
If I build the same connection with the second qnap switch instead of the ubiquity it is working flawlessly.
As I am not sure if I should keep it return it I hesitated to do anything else than using it as a dumb switch.
It’s just two switches.
Server 1 — 10Gbe — ubiquity switch — 10Gbe — qnap switch — 10Gbe — server 2.
I can’t help you identify the root cause, but I know there are fake display HDMI adaptors imitating a connected display people use to realize headless gaming VMs.
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
