I have never upgraded to 10GB ethernet before. I have 2 Cisco 2960s switches. I was wondering what hardware I need to add to my switches to make them function at 10GB. I was also wondering which area of my network actually benefits from the 10GB switches, my virtual servers, ect, and if so do they need 10GB nic cards? Any detail you could give me so that I can have a better understanding of the benefits and whats involved would be appreciated?
