Hardware Monitoring
The latest hardware from TYAN is equipped with Baseboard Management Controller
(BMC) from QLogic Zircon, which provides not only system monitoring but also remote
manageability. The BMC can always monitor the hardware regardless of how the
operating system is running. With the BMC onboard, any IPMI-compliant software can
monitor, control or diagnose the hardware locally, or from a remote site.
Protocol and Standard
•
Intelligent Platform Management Interface (IPMI)
•
Remote Management and Control Protocol (RMCP) for IPMI-Over-LAN
•
Alert Standard Forum (ASF)
Auxiliary Communication Interface
Other standard devices that the SMDC communicates with:
•
IPMB = Intelligent Platform Management Bus
•
EMP = Emergency Management Port
•
LAN = Local Area Network
Auxiliary SMBus / I
2
C buses
The SMDC provides 4 dedicated and independent buses for user expansion. A lot of
devices including Northbridge, Southbridge, Super I/O, Hardware Monitor, LAN
controller, etc. provide I
2
C communication. These I
2
C buses bridge the proper
communication between these devices.
Teaming with other IPMB Devices (PMCs and EMCs)
Numerous devices in the market already support IPMB communication. BMC
facilitates the control and management of these mentioned devices. PMC stands
for Peripheral Management Controller and EMC stands for Enclosure
Management Controller.
Depending on the overall set up of the system, the SMDC could initialize and
communicate with other PMC/EMC residing on the same IPMB bus. Simply connect
the devices to designated IPMB connector.
Examples of PMC/EMC Devices include:
•
Satellite controller - SCSI RAID controller unit
•
Power supply - power supply unit that has a hardware monitoring chip inside
