How can i run two LAN Cards on SAP B1 Server Machine

Hi Experts,

We have two LAN Cards on our server machine ,it is causing the slow performance of sap b1 clients. When i disable one LAN Card the speed for B1 clients is normal.

But i need to have two LAN Cards on my server one for storage and one for network.

SO is this possible two run two LAN Cards without effecting the performance of SAP B1

Thanks
