In today’s world, there is an
expectation that systems are “
always available”.
Every application is
“mission essential”.

Putting a perspective on the cost of downtime…..
Industry Segment Normal Cost of Downtime Peak Cost of Downtime
Discrete Manufacturing €49,000 €247,000
Process Manufacturing €19,800 €762,000
Banking €828,000 €2,698,000
Telco €192,000 €499,000

Technology to “de-risk”
aggressive virtualization deployments
Always or “Continuously” available
Simple to operate and maintain uses commercially available
operating systems everything is “hotplug”

Constantly changing data is needed in real-time to make
decisions
15
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
importance

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”

Stratus Failsafe software
33
Reliably distinguishes software issues from hardware issues to speed problem resolution – TRANSIENT ERROR PROTECTION
34
Driver hardening ensures uninterrupted processing if an I/O interface fails
35
Rapid disk resynchronization transparently mirrors disks and protects data integrity
