The server is a direct interface

between a business and its customers

16

Availability of the application is a

direct contributor to revenue

17

Single transaction is of enormous

value or critical

Self-checking logic detects and isolates errors to the component level and notifies Stratus of problems

If hard error occurs, faulty component is taken out of service; duplicate component continues normal processing – ZERO LATENCY

23

What happens to the data?

24

Disks run in Full Duplex mode

25

Memory is mirrored and synchronised

26

Network ports are duplicated and “teamed”
