When reading the specifications for the LSi SAS 9206-16e HBA, it says

Storage Connectivity; Data Transfer Rates
* 16 ports; 6Gb/s SAS 2.1 compliant 

SAS Bandwidth   
* Half Duplex 2400MB/s, x4, 6Gb/s SAS lanes

Port Configurations
* 16 ea, x1 ports (individual drives)
* 4 ea,  x4 wide ports
* 2ea, x8 wide ports

Connectors
* Four (x4) mini-SAS HD external connectors (SFF8644)

So there are 4 physical connectors.

Question

What is the bandwidth for each of the connectors?

I would be temped to say 6Gb/s * 4, but then it mentions the "Port Configurations" and 2ea, 4ea, 16ea, which I don't understand what is.

Does this mean, that the 4 physical connectors are not identical?
