Server Management

5.1Sahalee Baseboard Management Controller (BMC)

The Sahalee BMC contains a 32-bit RISC processor core and associated peripherals used to monitor the system for critical events. The Sahalee BMC, packaged in a 156-pin BGA, monitors all power supplies, including those generated by the external power supplies and those regulated locally on the server board. The Sahalee BMC also monitors SCSI termination voltage, fan tachometers for detecting a fan failure, and system temperature. Temperature is measured on each of the processors and at locations on the server board away from the fans. When any monitored parameter is outside of defined thresholds, the Sahalee BMC logs an event in the system event log.

Management controllers and sensors communicate on the I2C*-based Intelligent Platform Management Bus (IPMB). Attached to one of its private I2C bus is the Heceta5, an ADM1026 device, which is a versatile systems monitor ASIC. Some of its features include:

•Analog measurement channels

•Fan speed measurement channels

•General-Purpose Logic I/O pins

•Remote temperature measurement

•On-chip temperature sensor

•Chassis intrusion detect

The following table details the inputs/outputs of the Sahalee BMC as used in the SE7501WV2 server system.
