StorMagic SvSAN: sovereignty score and 8 European alternatives

SvSAN is StorMagic's virtual SAN software. It creates highly available shared block storage from two servers, aimed at edge sites and small data centres. A lightweight remote witness decides which server becomes primary if the link between the two nodes fails, and the two servers can have different hardware. SvSAN runs on x86 servers alongside VMware vSphere, Microsoft Hyper-V or KVM hypervisors, and is delivered as software that the customer installs on its own hardware.

StorMagic is a British company, co-founded in Bristol, England, which places it outside the EU and EEA. SvSAN is not a hosted service: storage data stays on the customer's own servers. Ownership and data processing terms should be confirmed directly with the vendor before purchase, together with the support and remote-access arrangements and the licence terms.

Why digital sovereignty matters with StorMagic SvSAN

StorMagic SvSAN is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

StorMagic SvSAN runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

StorMagic SvSAN is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs StorMagic SvSAN together with your other vendors and gives a total score, a heatmap and the main risk drivers.
