l
Host CNC ports configured with SFPs supporting the following:
o
4/8/16 Gb FC
o
10GbE iSCSI
o
1 Gb RJ-45
l
Host interface ports configured with 12 Gbit/s HD mini-SAS (SFF-8644) connectors.
Host CNC Ports Configured with SFPs (FC or iSCSI)
The following figure shows CNC ports configured with SFP+ transceivers that support 4, 8, or 16 Gb FC, or
10 GbE iSCSI connections. The SFPs look identical. Refer to the CNC LEDs that apply to the specific
configuration of your CNC ports.
