Padma has linked the product page for UCS. There is no 6250, but a 6248 and 6296 fabric Interconnect. 6200 is the latest 2nd Gen series of fabric interconnect. The xx48 & xx96 refer to the point count on the devices.
The 6200 series Fabric Interconnect is similar hardware to a Nexus 5500, with additional memory, flash and runs UCS manager software on top of it.
In a nutshell, they are both built off the Nexus platform, but the UCS 6200 is the fabric interconnect which has UCS Manager embedded in the interconnect and the Nexus 5k is a true FCoE switch and I am sure you understand what FCoE is???
If you are wondering can you take a 5k and make it a FI, then the answer is no. Because the 5k can do Fabric and Ethernet, then in a Flexpod configuration it could act as a fabric switch for storage.
That is in a nutshell, I am sure Padma, Rob and Michael could expand, but I will start here.
