System Overview
1-4 AlphaServer 1000A Rackmount Owner’s Guide
System Features
The system provides a number of special features that enhance reliability, ensure
availability, and improve 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.
Variable fan speed
Adjusts fan speed according to system
temperature.
Internal sensors
Monitor and detect internal system
temperature, fan failure, and 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 SCSI-2 controller
Supports tape, CD-ROM, and hard disk
drives without use of an expansion slot.
