Alpha Family Systems Summary
A complete family of open systems with
exceptional performance
The Alpha family: Where else can you find so
many powerful and open systems in a single,
compatible family? These systems give you the
freedom to choose from several operating
systems, thousands of applications, and a whole
marketplace of industry-standard I/O devices.
The Alpha family includes a complete range of systems,
from AlphaStation(TM) workstations to AlphaServer(TM)
enterprise servers -- all based on the same 64-bit RISC
technology.
Alpha systems at a glance
o Industry-leading performance and price/performance.
o Industry-standard PCI, ISA, and EISA slots let you
connect the inexpensive, commodity devices that work
best for your needs.
o Three-year hardware warranty for most AlphaStation and
AlphaServer systems the best in the industry for
RISC-based systems.
o Choice of operating system: DEC(TM) OSF/1(¨) for the
most standards-compliant UNIX(¨) operating system in
the industry; OpenVMS(TM) for exceptional business-
critical computing; Windows NT(TM) for unprecedented
Microsoft(¨) Windows(TM) power and performance.
o Imagine solutions that offer enduring value and that work for
today and tomorrow...technology that opens the way for
innovation by enabling you to take advantage of totally new
ways of computing...computing without boundaries that can
actually change the way people and computers interact.
