Server & Hosting

A professional-grade storage system. Multiple hard drives and components work together to store data quickly and reliably. If one component fails, others take over. SAN systems are used where data is critical and downtime is costly. For you, this means your website isn't stored on a single disk, but on a robust system.

A SAN separates the storage from the server. Instead of having hard drives in the server, it accesses a central storage array via its own network. This sounds complicated, but it's the reason why failover works at all: If one computer fails, another can immediately continue accessing the same data.

The trade-off is an additional path. Local NVMe drives respond in approximately 0,1 milliseconds, while a good SAN takes 0,3 to 1 millisecond. For a website with many small requests, this difference is noticeable, which is why fast environments often combine both: local storage for speed and a centralized network for fault tolerance.
