Hp 2930M - Bandwith errors

Hi all,

 

I've got two 2930M switches with a 10 Gbit modules at the back.

I've connected on each switch a server with two 10 Gbit interfaces. When doing an iperf speed test, I get a maximum bandwith of 5 Gbit. That should be 10 Gbit? What could be the problem causing a half bandwith?

 

The setup is simple. I've got 2 VLAN's, DATA & BACKUP. Each interface of the server is in one of the two vlans.

 

Kind regards,

Thomas
