Symbios 53C896 SCSI Controller

A Symbios 53C896 LVDS SCSI controller provides embedded SCSI on the primary 32-bit PCI
bus. The configuration registers define PCI-related parameters for the 53C896 device. The
53C896 supports all mandatory registers in the PCI configuration space header, including the
vendor ID, device ID, class code, revision ID, header type, and command and status fields.
The 53C896 supports two LVDS channels. One channel controls slow devices such as CD-ROMs,
and DVDs; the other channel provides a high speed connection to the internal LVDS drives or an
external disk array.

IDE Controller

The PIIX4 multifunction device on the PHP I/O baseboard acts as a PCI-based Fast IDE controller
that supports:
•
PIO and IDE DMA/bus master operations
•
Mode 4 timings
•
transfer rates up to 33 MB/sec
•
buffering for PCI/IDE burst transfers
•
master/slave IDE mode

Server Management (SM)

During normal operation, SM receives information about the status of the server. SM also
monitors the power supply voltages and operating temperature of the server. If SM determines
that the server is not operating within specified limits, it attempts to notify a supervisor or an
administrator about the condition of the server. The microcontrollers on the front panel board, disk
backplane, and PHP I/O baseboard implement the server management features.
