Thanks, is very useful document, however it doesn't explain value 2.8Gbyte/s. Besides, I don't understand restriction 4.8Gb/s on 8 SAS ports (page 15). If each port transfers 6Gbit/s, 8*6Gbit has to give 6Gbyte, right?
As far as I know, my controlers already have support of PCIe Gen3.
From Intel RMS25CB080 Datasheet:
Features:
...
4
x8 PCI Express Generation 3
1
interface for fast communication with the server board

At launch, compatibility will be limited to PCIe Gen2. PCIe Gen3 support is anticipated to be added by August 2012 and will require a module with a manufacture date that follows the
addition of PCIe Gen3 support.
