what values need to match for NIC and switch port

[robertkwild]

hi all,

im trying to tweak my nics for best performance ie speed as this servers going to be used just for transferring files from and to different network shares (each network share has a different nic assigned to it on the server)

on windows especially what advanced values on the nic have to match the values on the switch port ie i know these need to match both ends ie nic and switch port

mtu

flow control tx and rx

anything else that need to match ie offloads ie RSS, RSC, LRO, LTO, TSO etc etc

thanks,

rob

You should ensure that the NIC is operating at maximum available speed(1G, 10G), and if you are looking to do bulk transfers of files you can maximise MTU through the whole path between client and server. Other than that I would look at means of transfer(which protocol, which software, software config, unicast/multicast) to increase performance instead. There will be very marginal - if any performance improvements in these NIC settings.

if i change the MTU on both server nic and switch port int, do i need to change the MTU settings on the network share ie the server where im copying file to as well?
