DCB - Force10 MXL and Equallogic PS6210 - worth it or not?

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.
