They can operate over XFP to SFP+ cable

The XFP to SFP+ cable (10 Gigabit Small Form Factor Pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber, along with its interface to other electrical components which is called XFI. XFP to SFP+ cable modules Per the title, this is really about the EMC Clariion, not RamSans.  Since the RamSan 500 was fronted with the DRAM cache, and the EMC CX4 series contains cache as well What I am getting at is there seems to be the possibility of flooding the Service Processors cache with flash based storage data, depending on change rate.XFP to SFP+ cable is used to provide 10Gb/s serial links for 10 GbE datacom (belly-to-belly for high density applications) and storage area network (SAN/NAS) applications based on the IEEE 802.3ae and Fiber Channel standards.
