100% uptime for 20 years?
So what makes OpenVMS so much more stable than Unix? What is the
difference?
The short answer is that uptimes like that are VMS *cluster*
uptimes. Individual hosts don't necessarily have that uptime, but
the cluster availability is maintained for extremely long periods.
You can probably find more discussion of this in comp.os.vms.
And the 15MB/sec of I/O throughput on that state-of-the-art cluster
is something to write home about? ;)
Seriously, as someone alluded to earlier, we're not comparing
apples to applies. And a 9000 series VAX Cluster was one of the
earlier multi-user systems I worked on for reference ;)
Making that kind of stuff work with modern expectations and
tolerances is a whole new kettle of fish...
OpenVMS runs on modern gear (Itanium).
