Yes. It should get close to 1 GB/s where 1GbE is limited to about 125 MB/s.
Lower latency? Probably since most Ethernet drivers set interrupt coalescing by
default. Intel e1000 driver, for example, have a cluster mode that reduces (or
turns off) interrupt coalescing. I don't know if ceph is latency sensitive or
not.
Sorry, I meant 10GbE.
10GbE should get close to 1.2 GB/s compared to 1 GB/s for IB SDR. Latency again
depends on the Ethernet driver.
We're using bonded active/active 2x10GbE with Intel ixgbe and i'm able
to get 2.3GB/s.
Not sure how to measure latency effectively.
