Hello. currently we have six 9506 directors. When we originally bought them we had only the 1/2 DS-X9016 modules (16 port module running at 1 or 2 Gbs). Since then we have installed the DS-X9148 (48 port module) and the DS-X9304-18K9 (18/4 module with 4 GigE ports).

I know that the 48 port module is over subscribed with 12 ports in a port group sharing about 12.8 Gbs. Is the 18/4 module also over subscribed or can all 18 ports run at 4Gbs?

Thanks - Brad
