4.3.2.1 SATA Enclosure Management Controller
The QLogic* GEM424 enclosure management controller for the SATA backplane monitors
various aspects of the storage enclosure. The chip provides out-of-band SAF-TE management
through the SATA Host I
2
C interface. The GEM424 controller also supports the IPMI
specification by providing management data to a baseboard management controller through the
IPMB.
The GEM424 controller has general input and output pins (GPIOs) that allow for customization.
These GPIOs are used for hardware drive detection and driving FAULT and ACTIVITY LEDs.
The GEM424 controller comes in an 80-pin Thin Quad Flat Pack (TQFP) package and operates
from 3.3V and an input clock frequency of 20MHz.
4.3.2.2 SATA Interface
The GEM424 controller implements SAF-TE over the HBA I
2
C interface. The GEM424 controller
supports the following SAF-TE Command Set:
 Read Enclosure Configuration
 Read Enclosure Status
 Read Device Slot Status
 Read Global Flags
 Write Device Slot Status
 Perform Slot Operation
4.3.2.3 I
2
C Serial Bus Interface
The GEM424 controller supports two independent I
2
C interface ports with bus speeds of up to
400Kbits. The I
2
C core incorporates 8-bit FIFOs for data transfer buffering. The I
2
C bus supports
a National* LM75 or equivalent I
2
C -based temperature sensor. This enables actual temperature
value readings to be returned to the host. The Intelligent Platform Management Bus (IPMB) is
supported through the I
2
C port 0.
The following figure provides a block diagram of I
2
C bus connection implemented on the 6HDD
SATA HSBP.
