HA Cluster - High Availability without Compromise

High Availability Options Tailored to your Requirements

Site-to-Site High Availability and
Resilience

euroNAS Metro Cluster functionality enables businesses to synchronize storage infrastructure across geographically separated locations. This solution delivers seamless business continuity, even in the event of a complete site failure. Data mirroring operates across buildings within a campus or across the city, ensuring real-time synchronization. 
Key benefits
  • Secure Site Mirroring: Real-time data replication across locations with immediate failover capabilities. Synchronous replication ensures zero data loss and uninterrupted business operations.
  • Automatic Failover and Failback: Site failures trigger immediate automated failover without administrator intervention. Automatic failback re-establishes full redundancy upon site restoration. 
  • Optimized Read and Write Performance: Local read operations maximize speed while write operations utilize synchronous replication. Performance scales with network speed and latency  between sites.
This architecture is ideal for organizations operating geographically distributed infrastructures requiring high availability and resilience across extended distances. 

Dual Controller Configuration - Maximum Performance with Shared Storage

euroNAS Dual Controller configuration delivers maximum performance and availability within single data center environments. Both nodes access identical shared storage, ensuring optimal efficiency and speed while maintaining enterprise-grade availability. 
 
Key benefits
  • Shared Storage Architecture: Both nodes access identical storage for extremely fast data processing. Network-based data replication is eliminated, maximizing performance
  • Seamless Automatic Failover: Node failure trigger immediate service takeover without interruption. Shared storage architecture ensures seamless transitions without data copying or re-synchronization.
  • Optimized for High-Performance Environments: Perfect for single data center deployments prioritizing both performance and availability.
 This architecture is ideal for virtualisation, databases and critical applications requiring maximum performance within centralized environments
If you’re running a virtualised environment or simply trying to meet the demands of the 24-hour business cycle, you cannot afford downtime. With HA Cluster, you will get the highest level of redundancy, data security, reliability and availability possible, eveen in the event of a complete server failure.

What does HA Cluster do?

Automatic Failover Protection
When a storage server experiences failure, HA Cluster immediatley transitions operations to the secondary server with zero manual intervention required. This seamless failover capability ensures continuous business operations and eliminates costly downtime.
Enterprise-Grade Performance & Flexibility 
Our Storage OS deploys in minutes, delivering enterprise-class performance without vendor hardware lock-in. Organizations benefit from maximum operational flexibility while maintaining cost efficiency – essential for scalable IT infrastructure. 

HA Cluster Software is purpose-built for mission-critical business environments. Installation takes minutes, ensuring your data remain accessible even during system failures.

Comprehensive Protocol Support for Maximum Flexibility 

euroNAS HA Cluster supports a comprehensive range of protocols, accommodating diverse use cases and infrastructure  requirements:
  • iSCSI: Block-level access optimized for virtualisation environments and database storage provisioning
  • SMB: Cross-platform file sharing for Windows, Linux and macOS environments
  • NVMe over TCP: NVMe storage access over standard Ethernet networks without specialized hardware
 
This protocol diversity makes euroNAS the optimal choice for businesses with heterogeneous IT environments requiring both performance and flexibility.
Key Benefits:
  • Maximum Availability: 24/7 data and service availability, even during system failures
  • Unmatched Performance: Optimized configurations for distributed multi-site or high-performance local deployments
  • Flexible Architecture: Multi-protocol support ensures seamless integration into any IT infrastructure
  • Proven Technology: Nearly 20 years of reliable storage solutions for global enterprises

 

Rapid Deployment and Management

HA Cluster installs and configures in under 30 minutes, featuring intuitive web-based management with automated email notifications and monitoring capabilities. Advanced mirroring technology and continuous data replication enable planned maintenance on cluster nodes without impacting network applications or client data access.
With euroNAS, I immediately understood the installation and configuration, which can often be confusing with other systems. For me, complex solutions must be understandable for users and that is the case with euroNAS. The support is great and the cluster has been working perfectly since then.
