What switch should I buy if I want to get 2:1 oversubscription ratio?


Userlevel 4
I have a very high bandwidth data center and I need 2:1. It looks like a lot of the 10Gbps switches have only 4 up-links.

e.g.:
(48 downlink ports * 10Gbps = 480 Gbps)
(4 uplink ports * 40Gbps = 160 Gbps)
480 / 160 = 3:1 Oversubscription.

Should I get a 32x40Gbps? Is there breakout cables? Any other options?
