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.
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?
I would like to connect an external SuperMicro disk shelf with 45 SATA 7200RPM disks. From what I have heard, then the maximum bandwidth I will be able to get out of such a diskshelf is 24Gb/s. So my interest in this question is do I need 1 or 2 cables?
