High Availability Solution for Mission-Critical IT – FailXafe HA
High Availability (HA) is designed to reduce downtime by using redundant systems and automated failover when a server or system becomes unavailable.
FailXafe HA provides a virtualized high availability solution that helps reduce service interruption through automated failover between active and standby environments.
Prevent Downtime in Mission-Critical IT Systems
Key features
High Availability (HA)
Improve system availability and reduce the impact of server failures through redundant infrastructure and automated failover.
In high availability mode, one machine is actively running while the other is on standby, ready to take over in case of a failure.
This helps reduce service interruption when workloads are transferred to the standby environment.
Automatic Failover
​
When the active server becomes unavailable, FailXafe HA automatically transfers the protected workload to the standby server, helping reduce recovery time and operational disruption.
Simplified System &
Software Management
​
A streamlined console for system and software management that allows administrators to effectively manage multiple VM and system resources settings with ease.
Streamlined Security
​
Edge computing security is made more manageable through various security features, including a host-based firewall, restricted USB ports and secure communication protocols.
These features work together to minimize security risks.
Compatibility
​
Seamlessly integrate with your existing commercial off-the-shelf (COTS) servers, eliminating the need for costly and time-consuming custom hardware procurement.
A flexible solution that can adapt to your business's evolving needs, making it a
cost-efficient option for your organization.
Built-in Virtualization
​
Configure scalable virtual machines to run business applications.
The system works with both Linux and Windows OS, and provides a user-friendly console for managing and monitoring of the virtual machines.
System Architecture
How Does FailXafe HA Solution Work?
FailXafe HA uses two interconnected physical servers, both configured for virtualization and capable of hosting protected virtual machines.
One VM runs as the active workload, while a corresponding VM remains on standby.
I/O and application data are synchronized between the two servers so that, if the active server or one of its critical components becomes unavailable, the standby server can take over automatically with minimal service interruption.
Protecting Mission-Critical Applications In A Physical Environment Vs. Virtualization
Diagram 1: Conventional, silo-based approach to High Availability
Diagram 1 shows a conventional, silo-based approach to availability and disaster recovery, where different applications may rely on separate protection methods. Managing multiple independent solutions can increase operational complexity, maintenance effort and the risk of service interruption.
​
A virtualized High Availability environment can simplify protection for mission-critical applications by consolidating workloads onto redundant server infrastructure. FailXafe HA adds active-standby protection and automatic failover, helping reduce service interruption when a protected server or component becomes unavailable.
