Introduction
The increasing reliance on digital services places a clear expectation on IT infrastructure it has to be reliable, consistently available, and straightforward to operate.
The euroNAS HA (High Availability) Cluster is designed to meet that requirement directly. It provides a resilient platform for applications and data, ensuring that services remain available in the event of node failure, without introducing unnecessary operational complexity.
At its core, the platform operates as a two-node HA system. Depending on the deployment model, it can be configured either as a shared storage dual-controller solution within a single site, or as a synchronously mirrored cluster for resilience across nodes or locations. In both cases, the behaviour is consistent services continue to run, and data remains intact, without the need for manual intervention.
The platform is hardware agnostic and supports standard x86 server infrastructure, allowing it to be deployed flexibly without vendor lock-in. It also supports a range of access protocols, including SMB, NFS, iSCSI and NVMe over Fabrics, enabling it to support both traditional file services and performance-sensitive block workloads.
This guide outlines the architecture, deployment models, and operational behaviour of the euroNAS HA Cluster, with a focus on practical implementation and real-world use.
High Availability
The main advantage of euroNAS HA Cluster liesis in its abilitydesigned to ensurekeep highservices availabilityrunning of IT resources. By utilizing multiple servers that work together aswhen a cluster,node datafails, exchangeusing betweena dedicated cluster control layer to continuously monitor node state and coordinate failover.
Workloads are available across both nodes, allowing services to continue on the remaining serversnode if one becomes unavailable. This process is automatic, with data consistency maintained inand no requirement for manual recovery.
Failover is handled quickly enough that applications typically do not register an interruption, and from a user perspective the eventservice ofremains a server failure. This allows for near-continuous uptime and minimizes downtime, which can have costly implications for business operations.consistent.

The underlying data is kept in sync between nodes, allowing services to continue without the need to move or rebuild data.
On the network side, everything is handled through the built-in virtual switch layer. Interfaces can be addedbonded for resilience and additional throughput, and VLANs can be used to accommodateseparate traffic properly. This also allows for micro-segmentation, so storage, client access, and management traffic can be isolated as required.

You also get visibility across the whole environment, with telemetry covering storage, network, and I/O throughput. That means you can see what’s actually going on across the platform, rather than piecing it together node by node.
The result is a system that stays straightforward to manage, without losing the level of control the entire cluster. This reduces complexity, and ITinsight staffyou canneed focusin ona moreproduction criticalenvironment.

Troubleshooting and Recovery

This allows recovery to happen quickly and predictably, maintaining service availability and data consistency without manual intervention.
