System Overview
!
Burst transfers up to a peak of 132 MB/s
!
8-, 16-, or 32-bit data transfers
!
Parity enabled.
SAF-TE Controller
The system has an SAF-TE (SCSI Accessed Fault Tolerant Enclosure) controller that
provides an interface to the disk subsystem that supports status signals, hot swapping
drives, and enclosure monitoring.
The transport mechanism for the standardized alert detection and status reporting is the
SCSI bus. disk drives, power supplies, cooling fans, and temperature are continually
monitored and the conditions then reported over the SCSI bus to the system. When used
with RAID management software the user can be alerted of impending or imminent
conditions requiring attention. This allows the user to react to conditions that could
normally go unnoticed until data loss.
Real-Time Clock/Calendar
The real-time clock provides system clock/calendar information stored in a non-volatile
memory (NVRAM). The real-time clock battery provides power backup for the real-
time clock.
BIOS
The BIOS and Setup Utility are located in the Flash EPROM on the system board and
include support for system setup and legacy device configuration. A number of security,
reliability, and management features also have been incorporated to meet vital server
needs.
Controllers
The following provides a description of the controllers.
IDE Controller
The system includes a single channel enhanced IDE 32 bit interface. The controller has
a connector located on the system board that supports one device. The IDE controller
provides support for the internally mounted CD-ROM.
The device controls:
!
PIO and DMA transfer modes
!
Mode 4 timings
!
Transfer rates up to 33 MB/s
!
Buffering for PCI/IDE burst transfers
!
Master/slave IDE mode.
