The Smarter Approach to Uptime^™

Stratus Continuous Processing technology offers you the most complete set of availability safeguards in the business.

These Stratus innovations are the result of more than two decades' experience of assuring uptime for the world's most demanding applications.

Lockstep technology.

Lockstep technology uses replicated, fault-tolerant hardware components that process the same instructions at the same time. In the event of a component malfunction, the redundant component provides an active spare that continues normal operation and averts system downtime. The system also eliminates transient hardware errors that could cause software failures if left unchecked.

Hardware logic, in the form of Stratus ASICs, provides the core error detection, fault isolation, and synchronization logic for the lockstep architecture.

While other servers may offer duplicated power supplies, fans, and disk drives, only Stratus provides protection for core system components including motherboards, processors, memory, I/O buses, and I/O adapters.

Failsafe software.

Our failsafe software works in concert with lockstep technology to prevent many software errors. Unlike typical servers or clusters, ftServer hardware and software handles such errors transparently, shielding the operating system, middleware, and application software. Even in-memory data is constantly protected and maintained.

Management and diagnostic features also capture, analyze, and notify Stratus of software issues. This allows support personnel to take a proactive approach to correcting software problems before they recur. Our hardened device drivers also add considerable reliability to the Windows environment on ftServer systems.

ActiveService^™ architecture.

Component replacement takes place while the system continues normal operations. Hot-swappable components allow users to accomplish the task themselves.

Remote support capabilities - made possible by the system's ftServer Access Adapter and our global ActiveService Network - enable our service engineers to troubleshoot and resolve problems online more than 95% of the time. If necessary, the system automatically orders its own hot-swappable replacement part and ensures the correct part is delivered within 24 hours to key locations worldwide. Users can install replacement components easily while the ftServer system continues to run uninterrupted. What's more, our secure Web-based ActiveService Manager allows Stratus and customer-authorized vendors to collaborate on faster problem resolution.
