Hello gurus,
We can easily get 10Gbit on a single port of a dual-port NC522SFP NIC card - on a DL580 G7.
However - when starting to transmit to the second port - the first port throttles down - and the sum total of both ports can't seem to exceed about 5 Gbit.
Is this the card? The firmware (we have the latest)? an OS limitation (Oracle/RHEL Linux)? The switch (Nexxus 5K) ?
Thoughts?
Thank you !
