3-1 Storage Backplane Options
RM43596 supports below backplanes:
2 x 24-port 3.5” SAS/SATA SAS29-pin passive backplane (Front)
2 x 24-port 3.5” SAS/SATA SAS29-pin passive backplane (Rear)
8 x 12Gb/s SAS Expander Card (Internal)
2 x 12Gb/s SAS Expander Card (External)
1 x 12Gb/s BMC Module
All available SAS/SATA backplanes include the following common features:
12Gb/s SAS and 6Gb/s SAS/SATA
SFF-8680 12Gb/s rated drive interface connectors, providing both power and I/O signals to attached devices
Hot swap support for SAS/SATA devices
I2C interface from a 4-pin connector for device status communication to the BMC over SMBus
LCM Display to indicate drive activity and status for each attached device
Functionality
The microcontroller has a master/slave I2C connection to the server board BMC. The microcontroller is not an IPMB compliant device.
The BMC will generate SEL events by monitoring registers on the HSBP microcontroller for DRIVE PRESENCE, FAULT, and RAID
REBUILD in progress.
