1-4 • Overview AlphaServer 1000A Owner's Guide
System Features
The system provides a number of special features that enhance its reliability, ensure
its availability, and improve its expansion capabilities, as well as facilitate hardware
management and improve security.
Reliability/Availability
•
64-bit Alpha RISC architecture Provides significantly better performance
than 32-bit architecture.
•
Error Correction Code (ECC)
memory and CPU cache
Allows recovery from most cache and
memory errors.
•
Dual SCSI backplanes
One SCSI controller for each backplane
allows fully redundant disk subsystems.
•
Second power supply
Provides redundant power as backup.
•
Variable fan speed
Adjusts fan speed according to system
temperature.
•
Internal sensors
Monitor and detect internal system
temperature, fan failure, power supply
temperature.
System Expansion
•
Flexible memory architecture
Provides a 128-bit data path with ECC
protection. System memory can be
upgraded from 16 MB to 1 GB using
memory options.
•
Seven PCI expansion slots, and
two EISA expansion slots
Accommodates industry-standard option
cards such as Ethernet, FDDI, SCSI, and
modems.
•
Integrated Fast Wide SCSI-2
controller with external SCSI-2
connector
Supports tape, CDROM and hard disk
drives without use of an expansion slot.
•
Integrated SVGA controller
Supports management and configuration
applications locally without use of an
expansion slot.
