Synchronous replication
Write operations are acknowledged only after two copies of the data have been created.
Storage resilience
Data safety built into the storage layer.
Website data is stored on a distributed filesystem designed to keep services available through disk and node failures, while maintaining replicated copies across the storage cluster.

Replicated write
A write is acknowledged after two copies have been created.
Core behavior
Resilience without tying data to one disk or server.
Traditional RAID improves disk reliability, but remains constrained by a single system and can complicate maintenance or expansion. EuroHost uses distributed storage so data can be replicated, moved and recovered across multiple storage nodes.
Automatic failover
If a disk or storage node fails, I/O is redirected to healthy storage while the missing replica is recreated.
Scalable capacity
Storage capacity can be expanded by adding storage nodes instead of rebuilding around a fixed local array.
Parallel I/O
I/O can be served across multiple nodes in parallel, with frequently accessed data accelerated by SSD-backed cache storage.
Failure handling
The storage system is designed to recover in place.
Failure handling happens inside the storage layer. Replicas are distributed with rack awareness, filesystem integrity is checked continuously, and applications keep standard filesystem semantics.
Rack-aware replication
Replicas can be distributed across rack failure domains so a wider hardware fault does not depend on copies stored in the same rack.
Standard filesystem access
The filesystem provides standard Linux security and access-control behavior for hosted applications.
Self-healing checks
Checksumming and periodic data scrubbing help detect inconsistencies and keep stored data consistent.
Concurrency control
Capability-based access allows multiple applications to perform I/O on the same file without relying on one storage node.
Storage lifecycle
Write, replicate, recover.
The key idea is simple: data is not treated as belonging to one physical disk. The storage cluster maintains replicated copies and can rebuild missing replicas when hardware fails.
Data flow
1
Write request
An application writes data to the shared filesystem.
2
Replica creation
A second copy is created before the write is acknowledged.
3
Failure recovery
If a copy becomes unavailable, healthy nodes continue serving data while replication is restored.
