Hello All,
I just installed the CRS305-1G-4S+IN, before I had a workstation with a big raid and a freenas server connected with an optical cable and SFP+ modules.
However I seem to have issues regarding the transfer speed using the CRS305-1G-4S+IN.
When checking the errors tab I can see lots of: Rx Pauses, Rx Overruns and Tx Pauses.
When I enabled "Flow Control Tx/Rx" It seemed to double the TX speed to 500MB/s from 250MB/s, however my internal raid and server can hit 1GB/s easy. With direct attach I could reach these speeds.
Any ideas what could be causing this?
My workstation is connected with an optical SFP+ module. The server with a copper cable.
SFP1 FINISAR CORP. FTLX8571D3BCL A AMK0NAY 12-38-11 850nm multi-mode fiber 49C 3.318V 8mA -2.192dBm -2.653dBm

SFP3 CISCO-MOLEX INC 74752-9026 A MOC12372548 08-09-18 3m copper
Any tips would be greatly appreciated!
Thx!
