Server mirroring via Fiber Channel

SAN Cluster is a high-availability software-defined storage for your Fiber Channel environments.
If one of the two servers in the replication network fails, the cluster system automatically switches to the second server – without the need for manual intervention. The transition is usually much faster than IP-based replication.

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 us you continue to rely on the hardware of your trust, but mostly at much lower cost than for proprietary storage servers.

Software-defined storage

It supports most servers and is compatible with most Fiber Channel storage appliances in the market. Thanks to hybrid cache tiering, you can even accelerate your existing storage and make even more out of it.

Client support

All relevant clients such as Microsoft Windows (Server 2008/2012, Hyper-V), VMware ESX / ESXi, Mac OS X including XSAN, StorNext, Citrix XenServer 5.x / 6.x, Linux, Unix are supported

iSCSI support

Connect your existing iSCSI storages and transform them into a powerful Fiber Channel appliance with real-time mirroring.

Fiber Channel incl. VAAI

Fiber Channel is the first choice for enterprise environments. SAN Cluster provides the maximum constant I / O speed. VAAI (vStorage API for Array Integration) support offloads the ESX Server.

Hybrid cache tiering

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


Snapshots are a useful addition to the usual backups and allow a very fast recovery of the data.
With snapshot functionality, data can be backed up from a given point of time with almost no performance loss and large memory usage.

Hardware RAID

In addition to the integrated Raid, it also supports a variety 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 HW Raid Manager automatically detects the supported Raid Controller and adapts to it – only the functions relevant for this Raid Controller are displayed (in a uniform interface).

The node will automatically shut down when the battery is low. Email notification will inform you about power outages. APC network and USB devices are supported.
E-Mail notificationServer will inform you about disk failure, power outages, UPS and cluster events.
