For instance, every nuclear power plant based on Siemens designs has a slew of ftServers from Stratus controlling their operations. Stratus is offering either 7.2K RPM or 15K RPM drives, since customers want either "fat or fast drives", as Lane puts it, and 10K RPM are neither. Um mit der heutigen, durch verteilte Computersysteme geprägten Zeit mitzuhalten, haben wir unser Angebot durch eine Reihe von … In a software-based approach, all data committed to disk is mirrored across redundant systems. Stratus ftServer verwendet einen hardwarebasierten Ansatz zur Bereitstellung fehlertoleranter Anwendungen und Daten. Well, sorry, it's the law. Stratus did not make configured pricing available for its machines, but says an entry ftServer comes in at around $13,000. Bei ftServer gibt es keine Wiederherstellungszeit, wenn ein Ausfall in einer einzelnen Komponente oder CRU auftritt. The available CRU simply takes over as the primary server until the unavailable CRU is replaced. "While hardware keeps getting more reliable over time, the bar for availability keeps going up and up. A Message from Stratus CEO Dave Laurello about the COVID-19 Virus We gather real time statistics from all global ftServer deployments that have the automated dial home feature activated. Even if customers could virtualize everything and cram it all onto one four-socket machine, they are jumpy about doing so even when the box is fully replicated by lockstepping hardware. Es sind keine zusätzlichen Failover-Skripte erforderlich, um die Anwendungsverfügbarkeit und Datenintegrität zu gewährleisten. When it comes to hardware-based fault-tolerant computing on x86 iron, there's really only two games in town: NEC and Stratus Technologies. Local failures are then handled by ftServer; complete site outages due to server room, fire/flood/disaster are handled by the DR failover module to your chosen disaster recovery site. how to manage them. We've streamlined processes to be cost effective for our customers but that puts more of a burden on IT infrastructure. Maynard, MA 01754, USATel#: +1 978-461-7000© 2020 Stratus Technologies. This solution is the world’s first software-based, fault-tolerant solution that supports single and symmetric multi-processor and multi-core Microsoft applications. Stratus hasn't sold SATA drives for a couple of ftServer generations now. Our Mission If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naively designed system, in which even a small failure can cause total breakdown. Local failures are then handled by everRun 2 x host fault tolerant protection; complete site outages due to server room fire/flood/disaster are handled by the DR failover module to your chosen disaster recovery site.

Stratus ftServer uses proprietary field programmable gate arrays (FPGA) to ensure lock-step processing across two identical halves of an ftServer system. Bei einem softwarebasierten Ansatz werden alle auf der Festplatte gespeicherten Daten über redundante Systeme gespiegelt. No additional failover scripts are needed to ensure application availability and data integrity. That was a Windows-based system, and discussions with Stratus about Linux distributions showed that although it had a Linux … Proprietary algorithms dynamically adjust checkpointing frequency, based on the type and amount of data changes and I/O throughput. Other issues are captured, analysed and reported to Stratus. And if anything, we are seeing increasing interest in fault tolerance for virtualized workloads," Lane said. Unsere Vision These latter Xeon 5500 machines are known as the V-Series, and they run the VOS operating system from Stratus and include the processor, memory, and lockstepping electronics created by Stratus. Avance 3.0 was announced at the end of July, and among other features included tweaks to support Intel's Xeon E5 family of server chips. When superb processing performance is vital and there is limited or no on site IT support available choose Stratus ftServer: the world's first, simple 'fault tolerance in a box' integrated solution. Thisreport isan introduction to fault-tolerance concepts and systems, mainly from the hardware point of view.
