HA clusterBenefits

Server mirroring via Ethernet

HA Cluster mirrors the data in real-time on two servers (synchronous data replication) over the network.

Shared storage via iSCSI, SAS or Fiber Channel

Both server nodes can share the shared memory via iSCSI or Fiber Channel.

Failover services for business continuity

If one of the two servers in the replication network fails, the euroNAS system automatically switches to the second server – without the need for manual intervention. HA Cluster supports all major network protocols and can provide the data via SMB / CIFS, AFP, NFS and iSCSI. Active Directory connectivity is also supported.

Not coupled to a specific hardware

Traditional storage server manufacturers often offer proprietary hardware tailored to their systems. Future expansions are very expensive or force you to buy more units. With euroNAS, you continue to rely on the hardware of your trust, but mostly at significantly lower costs than for proprietary storage servers.

Software-defined storage

euroNAS supports most servers on the market, but you can also run it as a cost-effective virtual storage appliance within a virtualized environment. You can connect your existing server to euroNAS and make more out of it.

Hybrid cache

With euroNAS Hybrid Storage Cache you get the best of both worlds. You can merge your SSD and SATA / SAS drives to get the maximum capacity AND maximum I / O rate.

euroNAS automatically analyzes the incoming data transfer and moves the blocks of data that are frequently accessed to the faster (SSD) drives. The longer the server is used, the better it adapts and the more effective the symbiosis becomes.

Client support

euroNAS supports all relevant clients in their native environment. eg Microsoft Windows (XP, 7, 8, 2003/2008/2012, Hyper-V), VMware ESX / ESXi, Mac OS X including XSAN, StorNext, Citrix XenServer 5.x / 6.x, Linux, Unix.

Active Directory

Your server can be set up as a member of an Active Directory domain. Users and passwords are then automatically synchronized with the domain. This makes it much easier for system administrators to manage users and permissions.

SMB/ CIFS support

euroNAS products support access via SMB protocol (SMB versions 1, 2 and 3) / CIFS

AFP support

AFP is the first choice for the MAC environments.

NFS support

Thanks to NFS support, connecting Linux / Unix clients or virtualization servers is very easy.

iSCSI incl. VAAI

iSCSI allows packing the SCSI commands into Ethernet packets for transport over IP networks. The iSCSI drive is located on the euroNAS server and can be on a single drive, integrated raid, or hardware raid. On the client, the drive appears as a local hard drive. It is possible to create multiple iSCSI drives on a drive and to enlarge them at any time. VAAI (vStorage API for Array Integration) support relieves the strain on the ESX Server. Chap authentication and LUN masking improves security.

NVMe over TCP

NVMe over TCP is a new protocol that provides better efficiency for SSD and NVMe disks. It also provides for new versions of ESXi that support this protocol


euroNAS snapshots are a useful supplement to the usual data backups and allow a very fast recovery of the data.

With the euroNAS Snapshot functionality, the data can be backed up from a given point of time with almost no performance loss and high memory consumption.

Hardware RAID

In addition to the integrated Raid, euroNAS also supports a large number of hardware raid controllers.

With the help of the Hardware Raid Manager, it is possible not only to read out the status of the Raid network, but also to configure it directly in the software. The Hardware Raid Manager helps to initialize the disks, create a raid / volume, define a spare drive or read out the log files of the controller.

The euroNAS HW Raid Manager automatically detects the supported Raid Controller and adapts to it – only the functions relevant to this Raid Controller are displayed (in a uniform interface).
For a list of supported controllers, see the Support section

Software RAID

In addition to the excellent hardware raid controller support, euroNAS also helps to significantly reduce the costs of a redundant storage system: euroNAS products also offer a particularly reliable, easy-to-manage integrated RAID functionality.

With euroNAS Software Raid you can connect all hard disks connected to your server to a euroNAS Software Raid.

euroNAS Software Raid hardly differ in functionality from the high-end hardware raid controllers.


euroNAS Server will automatically shut down when battery power is low. Email notification will inform you about power outages. SNMP network and USB devices are supported.

Network port bundling

Network ports can be bundled to achieve the highest possible redundancy and throughput.

E-Mail notification

euroNAS will inform you about hard drive failure, power failures, UPS and cluster events.
