Appendix C SFP+ Connectivity Options
We expect most initial implementations of 10GbE switches, iSCSI target adapters and host NICs will
utilize SFP+ form factor physical connections. The SFP+ based Direct Access Copper solution (DAC or
10GSFP+Cu) is a fairly short-haul solution restricted to cable lengths of less than 15 meters. The
standard copper SFP+ cable includes the SFP+ interface as part of the cable. Fiber SFP+ solutions will
require the purchase of separate interface modules that match the cable standard being used. Various
SFP+ cable options are listed in Table 4 below. The best practices presented in this paper do not
differentiate between SFP+ physical implementations. They should apply to any of the various SFP+
cabling solutions available.
