Chapter 3: MegaRAID SAS RAID Controller Characteristics
12GB/s MegaRAID SAS RAID Controller Family
The following table describes the jumpers and the connectors on the MegaRAID SAS 9341-8i RAID controller.
3.1.2 MegaRAID SAS 9361 RAID Controllers
The MegaRAID SAS 9361-4i 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 9361-8i low-profile SATA+SAS RAID controller controls eight internal SAS/SATA ports through two
SFF-8643 internal mini-SAS HD-4i connectors.
3.1.2.1 MegaRAID SAS 9361-8i 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 9361
RAID controllers. The following figure shows the jumpers and the connectors on the MegaRAID SAS 9361-8 controller.
NOTE The MegaRAID SAS 9361-4i RAID controller is the same as the
MegaRAID SAS 9361-8i RAID controller except that the J5A1 connector
on the MegaRAID SAS 9361-4i RAID controller is a single internal port
connector. The J5A1 connector on the MegaRAID SAS 9361-8i RAID
controller is a dual internal port connector.
NOTE Pin 1 on the headers and connectors is highlighted in red in this figure.
