Stratus® ftServer®

Continuous availability from the data center to the edge

Simple to deploy, manage, and service

In today’s always-on global economy, seconds matter. Downtime in critical business applications can have far-reaching economic, security and legal consequences. Recovering from a failure, no matter how fast, is simply no longer an option.

Nowhere is this more important than at the edge – the last mile of digital transformation for many. Companies are looking for reliable, secure, yet easy to manage edge computing infrastructure that’s highly interoperable with their data centers and cloud.

Optimized for distributed edge-in architectures, Stratus ftServer delivers the performance needed to support your advanced processor and data intensive applications, while also providing the fault tolerance, security and manageability required at the edge of your corporate networks.

ftServer Features

ftServer’s unique combination of Stratus IP and industry standard components delivers dramatically simplified continuous availability:

  • Automated Uptime Layer

    Patented lockstep processing ensures no transactions are lost. Multi-path I/O failover prevents data corruption or data loss.

  • Single system with fully duplexed hardware:

    Redundant components are presented as a single system – only one OS or application is required, saving licensing fees.

  • Versatile industry standard platform

    Uses industry standard x86 processors, memory DIMMs, SSDs and HDDs. Supports standard shrink-wrapped OSs from Microsoft, Red Hat, and VMware.

  • Proactive Health Monitoring

    Self-monitoring and self-diagnosing systems simplify issue management. Automated online parts replacement eliminates guesswork, and systems continue to run while being serviced.

  • Hot-swappable customer replaceable units (CRU)

    Subsystems or components are designed to be easily replaced. CRUs are automatically re-synchronized when reinserted.
