RE: System Uptime Measurements

["Cotes, Steven" <cotess@xxxxxxxxxxx>]

Rich,
The "uptime" numbers for the AS/400 are _very_ good.
Other responses have given you some numbers and I'm
sure IBM could quote Gartner or someone for you.

I wanted to toss out something for your thoughts.
When we started measuring availability, we looked at our business
goals and definitions. Users don't care if a system is running 99+%
of the time, they care that it is available for their use when they
expect
and need it. We kick users off for backups, update processing, MRP,
period-end close, etc. We publish what hours the system will be
available for users. Any non-available time during those hours counts
against us. Even if scheduled, if we don't let users on, it's not
available. We then compare our numbers to our historical and
our other systems.

We found these numbers to be more valuable then just system
running time.
