Support
of Multiple
Operating
Systems
Currently, the DEC 4000 AXP can run two different operating
systems:
• OpenVMS AXP
• DEC OSF/1 AXP
The NT AXP operating system and other operating systems are
planned to be supported in the future.
Integration
with Existing
Technology
The DEC 4000 AXP system is designed to be compatible with
existing technology:
• VAX hardware
DEC 4000 AXP, like all Alpha AXP systems, can connect to
your existing VAX hardware in clusters and networks.
• VMS and UNIX software environments
By upgrading the operating system software, existing
versions of VMS or OSF/1 can support any Alpha AXP
system.
DSSI
VMScluster
Support
A DSSI VMScluster configuration consists of two or more
systems, running VMS software, configured as a DSSI cluster
sharing their DSSI devices through a bus. Each system can have
direct access to any of the devices on a shared DSSI bus; this can
include a shared common disk.
