MegaRAID 6Gb/s SAS RAID Controller Family
The MegaRAID 6Gb/s SAS RAID controllers are dual PHY, SAS 
PCI Express RAID controllers and are used in a system with a

it is intended as a unifying I/O architecture for various systems: desktops, 
workstations, mobile, server, communications, and embedded devices. 
The following subsection provides graphics and connector information for 
the 6Gb/s SAS RAID controllers.
