Storage and virtualisation software for infrastructure you control
euroNAS develops complete, hardware-independent software for enterprise storage, high availability, Ceph and virtualisation. Each product includes its own operating environment; on bare metal, no additional host operating system is required.

Four complete operating platforms for distinct infrastructure roles—not applications layered on another OS.
Complete operating platforms—not applications layered on another OS
euroNAS GmbH develops, licenses and supports complete infrastructure operating environments. Installed directly on qualified industry-standard server hardware, euroNAS provides the operating system and the storage or virtualisation services in one tested software stack. Customers and system integrators retain the choice of hardware, deployment model and access protocols.
Start with the outcome your infrastructure must deliver
Each euroNAS product serves a defined operating model. The correct starting point is the workload, availability, recovery, access method and growth requirement—not capacity alone.
Virtualisation
Build shared storage for VMware and Hyper-V, or evaluate eEVOS as an integrated virtualisation platform with Backup & Disaster Recovery.
Explore virtualisation →Enterprise storage
Provide file, block and S3 services from a standalone server, a Virtual Storage Appliance or a two-node high-availability design.
Explore storage technologies →Scale-out & object
Use graphically managed Ceph for distributed block, file and S3 services, explicit failure domains and multi-node growth.
Explore scale-out Ceph →Availability & recovery
Separate automatic service continuity, replication, historical recovery, cyber resilience and disaster recovery by event.
Explore resilience →Match the access model to the application
Protocol performance matters only after application compatibility, data semantics, path resilience and operational support are understood.
NVMe over Fabrics
NVMe/TCP and NVMe/RDMA for low-overhead network block access.
Explore NVMe-oF →RDMA
RoCE, RoCEv2 and InfiniBand across a correctly engineered path.
Explore RDMA →Fibre Channel
Dedicated SAN fabrics with established zoning and multipathing practices.
Explore Fibre Channel →iSCSI
Mature Ethernet block storage for broad host and application support.
Explore iSCSI →SMB & NFS
Shared namespaces, permissions and locking for enterprise clients.
Compare SMB and NFS →S3
S3-compatible application and backup storage with an integrated File Manager.
Explore enterprise S3 →Ceph
Scale-out block, file and object services across multiple nodes.
Explore Ceph with eEKAS →Block, file or object?
Understand who owns the filesystem, namespace and data lifecycle.
Compare data models →A faster protocol cannot correct the wrong data model. Validate the application, host, network, storage and recovery path as one service.
Five operating models—not one universal platform
The right model follows the failure boundary, growth pattern and operational responsibility of the service.
Standalone or VSA
hosts
system
Focused file, block and S3 services on one server or virtual appliance.
Two-node failover
Synchronous Mirror or dual-controller shared storage with automatic service takeover.
Virtualisation cluster
Hyper-V
NVMe-oF
Shared block storage without a fixed two-compute-node limit.
Distributed Ceph
Block, file and S3 across explicit failure domains with multi-node expansion.
eEVOS
VMs
storage model
Virtualisation, availability and integrated recovery in one operating environment.
Support the platform you run—or choose an integrated alternative
Existing hypervisor estates and new consolidated platforms require different decisions. euroNAS supports both approaches through dedicated storage and virtualisation platforms.
Four euroNAS products, each built for a distinct infrastructure role
These are licensed software platforms rather than fixed-branded appliances. Final selection requires workload, compatibility, availability, recovery and growth validation.
| Software product | Best-fit operating model | Key capabilities | Important distinction |
|---|---|---|---|
| euroNAS Premium | One physical storage server or Virtual Storage Appliance. | File, block and S3 services; snapshots and asynchronous replication options. | Focused scale-up storage. Product details → |
| HA Cluster | Compact two-node storage availability. | Synchronous Mirror or dual-controller shared storage; file, block and S3 services. | Automatic local failover; asynchronous replication remains a separate protection option. Product details → |
| eEKAS | Distributed multi-node storage and S3 services. | Graphically managed Ceph block, file and S3; File Manager, capacity quotas and billing options. | Scale-out requires appropriate node, network, failure-domain and free-capacity planning. Product details → |
| eEVOS | Integrated virtualisation, availability and recovery. | VM lifecycle, live migration, Backup & Disaster Recovery and Instant Backup & Recovery. | Consumes internal, shared or Ceph-based storage as part of the virtualisation design. Product details → |
Product availability and supported combinations should be confirmed for the intended software version, host platform and deployment topology.
Architectures proven in real operating environments
