Stratus ftServer

Continuous Availability Made Easy

Simple to deploy, simple to manage, simple to 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. What companies need today is failure prevention, not failure recovery. What they shouldn’t need is a PhD to set it up.

Stratus offers quick and easy failure prevention with ftServer. Conventional technologies such as clustering and virtualisation-based HA do not prevent downtime, but rely on recovering from hardware or software failures. And this recovery time can vary from minutes to hours. Only ftServer prevents the downtime of your critical business applications, ensuring continuous availability, even when your underlying hardware components fail.

Key benefits

ftServer is a fully integrated continuously available platform that helps companies maximise revenue, quality, and productivity:

No unplanned downtime:

Ensure application availability despite component failures. Ride through transient errors and power spikes that would take down other x86 systems

No data corruption or data loss:

Ensure all transactions are processed. Protect the integrity of both committed and in-flight data

Simplified deployment:

Get instant continuous availability without having to modify your software applications or write failover scripts

Simplified management:

Save time and effort with self-monitoring hardware, automated parts replacement, and customer replaceable subsystems

Lower total cost of ownership:

Save up to 40% when you factor in acquisition, deployment, management, and unplanned downtime costs

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.

Active service architecture:

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-synchronised when re-inserted.

Organisations that believe solving an availability weakness requires an "either", "or" decision should reconsider. VMware and Stratus ftServer can offer a better way to address the challenge.
