6Gb/s MegaRAID SAS RAID Controller Family
3.1.7 MegaRAID SAS 9271 RAID Controllers
The MegaRAID SAS 9271-4i low-profile SAS/SATA RAID controller controls four internal SAS/SATA ports through one
SFF-8087 mini SAS 4i internal connector.
The MegaRAID SAS 9271-8i low-profile SAS/SATA RAID controller controls eight internal SAS/SATA ports through two
SFF-8087 mini SAS 4i internal connectors. This controller supports a nonvolatile CVFM02 module that connects to a
CVPM02 module to provide backup for your data in case of power loss.

C Enclosure Management connector
3-pin connector
Supports SES (SCSI enclosure services) over I
2
C through an
internal I
2
C backplane cable.
J1B1 Serial EEPROM (SBR) 2-pin connector
Provides controller information, such as the serial number,
revision, and manufacturing date. The default is no shunt
installed.
J2B1 x4 SAS Ports 0 to 3 Internal connector SFF-8087 mini SAS 4i internal connector
Connects the controller by cable to SAS drives or
SATA 2 drives.
J2B2 x4 SAS Ports 4 to 7 Internal connector SFF-8087 mini SAS 4i internal connector
Connects the controller by cable to SAS drives or
SATA 2 drives.
J2B3 Advanced Software Options Hardware Key header 3-pin header
Enables support for the Advanced Software Options
features, which include CacheCade, FastPath, Recovery, and
SafeStore disk encryption.
J2B4 Standard Edge Card connector The RAID controller interfaces with the host system though a
standard edge card.
This interface provides power to the board and an I

C
interface connected to the I
2
C bus for IPMI.
J5A1 Serial Universal Asynchronous Receiver/Transmitter
(UART) connector for the Expander
4-pin connector
Reserved for LSI use.
J5B1 Board-to-board Mezzanine connector 240-pin DDR3 nonvolatile memory module interface
Connects the controller directly to a CVFM module. The
module can connect to an optional remote LSIiBBU09
intelligent battery backup unit.
Refer to the MegaRAID LSIiBBU09 Intelligent Battery Backup
Unit Quick Installation Guide for the procedure used to
connect a CVFM module to a remote LSIiBBU09 unit.
