Hello,  If the switches are dedicated for iSCSI use, then there is no benefit to using DCB.  DCB by itself doesn't make iSCSI faster.  I just makes sure that non-iSCSI traffic doesn't interfere by providing iSCSI with a higher priority.  All other traffic goes into a "lossy" class of service.  Also you will need DCB converged network adapters to use DCB on the hosts.  Most software iSCSI adapters don't support DCB.   Regards,  
Good morning All I have a new virtualisation environment of 3 M620 blades, 2 x Force10 MXL switches and 2 x Equallogic PS6210 - there is the option of using DCB - is it worth setting up DCB, will I get any gains or better stability from it, or for such a small environment should I just use the standard iscsi configuration?  Any thoughts or alternate options gratefully received.  Thanks 
DCB - Force10 MXL and Equallogic PS6210 - worth it or not?
