Fibre Channel
System component Description
Fibre Channel ports 48 SFP+ ports that support any combination of Short Wavelength (SWL) and Long
Wavelength (LWL) or Extended Long Wavelength (ELWL) optical media.
4 QSFP ports that support 16-Gbps or 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.
• 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.
• 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 and 4 Gbps transceivers are not supported.
