Fibre Channel
System component
Description
Fibre Channel ports
9
96 SFP+ ports that support any combination of short wavelength (SWL) and long
wavelength (LWL) or extended long wavelength (ELWL) optical media. 16 DD ports
that support 64G SFP-DD or SFP+ transceivers. The SFP+ ports are capable of
autonegotiating to 8, 10, 16, 32, or 64G speeds depending on the SFP+ model and
the minimum supported speed of the optical transceiver at the other end of the
link.
• A 64G optical transceiver can autonegotiate to 64G, 32G, or 16G.
• A 32G optical transceiver can autonegotiate to 32G, 16G, or 8G.
• A 10G optical transceiver can autonegotiate to 10G.
