Mapping to interconnect ports 
Several port types are referenced in the following tables. 
•  Examples of 1x ports are 1-Gb Ethernet (1 GbE) switch modules and Fibre Channel interconnect 
modules. 
•  An example of a 2x port is a Serial Attached SCSI (SAS) interconnect module. (Reserved for future use.) 
•  Examples of 4x ports are 10-Gb Ethernet (10 GbE) interconnect modules. 
•  Gen8 servers have FlexibleLOM adapters that have the same port mapping as the previous generation 
server blade Embedded NICs. 
 
  NOTE: 1x and 2x port mezzanine cards interface with single-wide interconnect modules. 4x 
port mezzanine cards interface with double-wide interconnect modules. 
 
The term "1x/2x" refers to the number of interconnect lanes per port provided by the controller. The more 
lanes provided per port, the higher the data transmission rate coming from that port.
