Hi guys,  I need two more network card modules for a PE R510 server. I see two options: 1. Search for a single network card with 2 LAN ports or 2. Search for two network cards with 1 LAN port each  Can you, please, tell me what kind of slots they fit in so I can also search or can you give me some network card models that fit into those servers?  rgds, Florin
