Fibre Channel
System component Description
Fibre Channel ports 96 SFP+ ports that support any combination of Short Wavelength (SWL) and Long
Wavelength (LWL) or Extended Long Wavelength (ELWL) optical media.
8 QSFP ports that support 32-Gbps QSFP transceivers.
The SFP+ ports are capable of auto-negotiating to 4, 8, 16, or 32 Gbps speed
depending on the SFP+ model and the minimum supported speed of the optical
transceiver at the other end of the link.
v 10-Gbps performance is enabled by 10-Gbps SFP+ transceivers provided the other
end of the connection is also of 10-Gbps speed.
v 4-, 8-, and 16-Gbps performance is enabled by 16-Gbps SFP+ transceivers provided
the other end of the connection is minimum of 4 Gbps speed.
v 8-, 16-, and 32-Gbps performance is enabled by 32-Gbps SFP+ transceivers provided
the other end of the connection is minimum of 8 Gbps speed.
Note: 2-, 4- and 8-Gbps transceivers are not supported.
