If SFP cost is an issue, are the distances involved too great for 10GBASE-T.

Thought I’d throw out a few questions and a request for some feedback around some datacenter switching we are looking at. Currently each server has 6 10GbE NICs of which two are dedicated iSCSI that will run through this fabric. <o:p class=""></o:p></div>

The current requirement is to replace our 1000BaseT switching with 10GbE but the cost of SFP+ modules is an issue and currently twinax has been rules out due do cable management issues (don’t ask :/).<o:p class=""></o:p></div>

It would be nice to also standardise for our core also so routing is a “nice to have” but not a requirement.<o:p class=""></o:p></div>

If we could get some decent or support 3<sup class="">rd</sup><span class="Apple-converted-space"> </span>party SFP+ modules for a good price it would make the Cisco/Brocade options much more attractive but never used the Startech or Netgear SFPs before & I’d
