- 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 partner component provides an active spare that continues normal operations and prevents system downtime. The system also eliminates transient hardware errors that, in-turn, could cause software failure. ftServer systems use a standard DMR (Dual Modular Redundancy) configuration which includes two CPU/memory units. The fault-tolerant I/O system is logically separated from the CPU-memory system. Hardware logic, in the form of custom ASICs, acts as a PCI bridge between the CPU and I/O, and also provides the core error detection, fault isolation and synchronization logic for the lockstep architecture. Fault-tolerant I/O is implemented using replicated PCI buses, replicated I/O adapters and replicated devices. Multiple paths are available to any logical I/O operation, including both internal and external storage operations. Any I/O operation failure will result in a retry using an alternate path ensuring successful completion of the I/O operation.

- Stratus’ Active Service architecture detects and reports problems before they cause system downtime. ActiveService architecture combines automatic fault detection and isolation with integrated call-home remote support and online component replacement to ensure a level of built-in serviceability that other vendors can’t match. ActiveService Access features allow the hardware to handle the first level of customer support, with the system correctly isolating faults, and automatically opening a call on the Stratus call system that tells the support center exactly what action to take. The remote support capabilities of ftServer systems allow service engineers to troubleshoot and solve problems online more than 95% of the time. If necessary, the system automatically orders its own hot-swappable replacement part. Users can install these components easily while the ftServer system continues normal operation. Out-of-band management capabilities are provided by the Virtual Technician Module (VTM). Running on independent power and network connections, the VTM allows remote communication to take place between Stratus’ ActiveService Network and the customer’s module — regardless of the system’s state. The VTM allows a service engineer to remotely power on/off or reset/ reboot the system and manages the security of incoming and outgoing communications through the ActiveService Network.
- The ActiveService Architecture has its foundation in the design of the hardware and its technology-enabled Access features. The system's self-monitoring and diagnostics features are capable of correctly identifying the specific hardware or software component that causes an abnormal condition. The elimination of guesswork and trial-and error-part swapping clearly sets ftServer systems apart from alternative high-availability solutions. In the event of component failure, the system automatically opens a call with the Stratus Customer Assistance Center that supplies information on exactly what action is needed. Most replacement components arrive within 24 hours. . The hot-pluggable components are easy to replace by users without special tools, commands or a visit from a field engineer. Once in place, the new component is automatically integrated into the running system. Throughout this entire process, you system and application will continue to run normally.
- Serviceability is built directly into the hardware and system software. This allows the ftServer system to automatically isolate component failures and report any failure immediately to the Stratus Customer Assistance Center (CAC). Our Advanced Exchange service enables us to deliver parts to every major location in the world within 24 hours. Our hardware enables us to deliver the correct part 100% of the time. Stratus offers a 100% availability program with our Assured Availability Plus Critical Service level.
- Notes: Describe the complexity and data loss the come with cluster implementations. Plants often don’t have IT people to manage clusters. Stratus systems are designed to handle hardware problems automatically, with no failover delay or data loss. Lockstep technology uses replicated fault-tolerant hardware components that process the same instructions at the same time. Hardware logic, in the form of Stratus chipsets, provides the core error detection, fault isolation, and synchronization logic for the lockstep architecture. Errors are detected and isolated to the component level and the system itself then notifies Stratus of any problems so that corrective action can be initiated immediately. Stratus systems are also built to withstand unpredictable transient errors that can lead to system downtime or cause silent data corruption on conventional systems and clusters. In the event of a component malfunction, the redundant component acts as an active spare that continues normal operation, thus averting system downtime. 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. In-memory data is protected from hardware failures by the ftServer lockstep architecture which maintains at least two copies of all memory data.
