The SMDC provides 4 dedicated and independent buses for user expansion. Many devices including Northbridge, Southbridge, Super I/O, Hardware Monitor, LAN controller, etc., provide I2C communication. These I2C buses bridge the proper communication between these devices.
Teamed with other IPMB Devices (PMCs and EMCs)
Numerous devices in the market already support IPMB communication. BMC facilitates the control and management of these 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 the designated IPMB connector. Available PMC/EMC options include:
•Satellite controller - SCSI RAID controller unit
•Power supply - power supply unit that has a hardware monitoring chip inside
Remote Monitor, Control and Diagnostics
Sensor Monitor
•Voltage
•Temperature
•Tachometers
•Fan Speed Control / PWM
•Chassis Intrusion
Control Command Set
•Power Up
•Power Down
•System Reset
•System Power cycle
•System NMI
•Watchdog Timer Diagnostic Command Set
•
•CPU Voltage Identification (CPU VID)
•ACPI State Detection
•Request Message Redirection through IPMB
•Remote Console Redirection over LAN
Remote Console Redirect over LAN
Remote Console Redirection allows IT managers to effectively control and maneuver text console of a remote machine. Serial console information goes through the M3291/3295 SMDC and is processed over the network. TSO software then reproduces the exact text console at a remote location. For example, someone may own a group of servers at a remote location and could change options of those servers from a completely separate location. Another example is that one may log in to the Linux serial console through M3291/3295 SMDC over the network.
See SMDC installation section for details.
