vServerFT
vServer Enterprise-Grade Fault-Tolerant is a cutting-edge fault-tolerant virtualization platform designed to ensure zero downtime and zero data loss for mission-critical applications. By clustering two independent physical servers into a single fault-tolerant system, it delivers seamless failover and continuous operation even during hardware failures.
The imperative of fault tolerant
In today’s digital-first world, 24/7 service continuity is non-negotiable. Virtual server fault tolerant is the lifeblood of business resilience.
How vServer delivers zero downtime
In today’s digital-first world, 24/7 service continuity is non-negotiable. Virtual server fault tolerant is the lifeblood of business resilience.
​
Layered redundancy
Protects compute, storage, and network layers to ensure uninterrupted operations during failures.
​
Hypervisor cluster architecture
-
Spans two physical hosts with specialized engines.
-
Engines run distinct processes while sharing real time VM states via a private cluster bus.
​
Failure detection
-
Continuous "heartbeat" checks via a dedicated VLAN for instant fault detection.
vServerFT Overview - Architecture
The vServerFT Fault-Tolerant System, architected on virtualization technology, guarantees business continuity and ensures that system failures do not result in loss of application availability or critical data.
​
With vServerFT, fault tolerant is achieved through the use of two redundant servers which present as a single operating environment. Critical applications continue to run despite component or system failures.
This implementation follows our Fault Tolerant Architecture designed for mission-critical environments.
