Hab 3 neue Server bekommen und nach der Installation von PVE und der Konfiguration eines Full Mesh Network (RSTP Loop Setup) folgenden Datendurchsatz mit iperf3 bekommen:

Code:
root@pve3:~# iperf3 --client 10.10.xx.xxx
Connecting to host 10.10.xx.xxx, port 5201
[  5] local 10.10.xx.xxx port 41210 connected to 10.10.xx.xxx port 5201

Sollte der Durchsatz mit dieser Karte (Ethernet Controller E810-C for SFP) nicht etwas höher sein oder kann die nicht mehr?

Die E810 sind eigentlich 25/100 GBit. Wenn du aber 10 GBit SFPs rein steckst, geht natürlich auch nur 10 GBit.
 
Hab die NICs direkt verkabelt, dann liegt es vielleicht an den Kabeln (Twinax Kuperfer)? Hatte ich bisher noch nicht...
Wenn das SFP+ sind dann sind das 10GBit DAC. Du brauchst SFP28 DAC für 25 GBit.

Soetwas z.B.
