Some time ago I have purchased a cisco catalyst switch (I dont remember the exact model) ,that has regular twisted pair Ethernet and two SFP ports. All this time I have been using the twisted pair Ethernet ones, but I would like to also utilize the SFP ports to gain some speed networking with my NAS storage. The trouble is I dont know anything about SFP transceivers. What do those support? Fiber maybe? What card will I need to purchase to connect to my servers? What SFP's and cable? Please give me an example setup on how to utilize the ports.

Thanks!

Without the model it’s hard to help you. It would be best to give us the model, then we will see if this is a sfp or sfp+ port. With sfp you are still limited to 1G. And even if it’s sfp+ and you connect your nas to it, the user is limited to 1G from the rj45 ports on the switch. So unless there are multiple users using an exzessive amount of bandwidth this will not help you at all.

Just for your information. You need a Gbic which is supported by you switch. This gbic can be with fiber (single or multimode LC) or also RJ45 1G or 10G. There are a lot of options.
