3.1 12GB/s MegaRAID SAS RAID Controller Family
The 12Gb/s MegaRAID SATA+SAS RAID controllers are dual-PHY, SAS PCI Express (PCIe) RAID controllers and are used
in a system with a PCIe slot. PCIe goes beyond the PCI specification in that it is intended as a unifying I/O architecture
for various systems: desktops, workstations, mobile devices, servers, communications, and embedded devices.
The following subsection provides figures and connector information for the 12GB/s MegaRAID SAS RAID controllers.
3.1.1 MegaRAID SAS 9341 RAID Controllers
The MegaRAID SAS 9341-4i low-profile SATA+SAS RAID controller controls four internal SAS/SATA ports through one
SFF-8643 internal mini-SAS HD-4i connector.
The MegaRAID SAS 9341-8i low-profile SATA+SAS RAID controller controls eight internal SAS/SATA ports through two
SFF-8643 internal mini-SAS HD-4i connectors.
3.1.1.1 MegaRAID SAS 9341-8i RAID Controller – Board Layout and Jumper and Connector Information
This subsection provides the board layout, and the connector and jumper information for the MegaRAID SAS 9341
RAID controllers. The following figure shows the jumpers and the connectors on the MegaRAID SAS 9341-8 controller.
NOTE The MegaRAID SAS 9341-4i RAID controller is the same as the
MegaRAID SAS 9341-8i RAID controller, except that the MegaRAID SAS
9341-8i RAID controller contains an additional internal port
connector, J1B.
