12 Gb SAS and 6Gb SAS/SATA



29-pin SFF-8680 12 Gb 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 3-pin connector for device status communication to the BMC over slave SMBus



LEDs to indicate drive activity and status for each attached device

5.4.1

I2C 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.

5.4.2

Intel Spare Product Code: FXX35HSCAR

The 3.5" drive system SKUs within the product family will ship with a 4x drive backplane capable of

supporting 12 Gb/sec SAS and 6 Gb/sec SAS / SATA drives. Both hard disks and Solid State Drives (SSDs)

can be supported within a common backplane. Each backplane can support either SATA or SAS devices.

However, mixing of SATA and SAS devices within a common hot swap backplane is not supported.

Supported devices are dependent on the type of host bus controller driving the backplane, SATA only or

SAS.
