Storage Spaces Direct clusters allows deployments as small as two servers for helping reduce hardware costs. Businesses with Remote Offices and Branch Offices (ROBO) will find this feature extremely beneficial and cost-effective.
Drive Fault Tolerance
Through built-in redundancies, as soon as any failures are detected the system will automatically self-heal itself to recover any lost data. By keeping multiple copies of your data, those same copies will be guaranteed to land on any number of the separate drives. This way if any one drive fails, not only is all your data safe, it also remains continuously accessible.
Chassis & Rack Tolerance
The same concept follows suit with your rack servers as well. When you tag each server in a rack or chassis with Storage Spaces Direct, the system will adapt all of its functions to place copies not only in different drives or in different servers, but also in different racks. Even through a rack outage, your data will be completely safe and continuously accessible.
Scale out effortlessly as your needs grow and claim more space simply by more compute nodes to existing clusters. The storage pool will also automatically absorb new drives for scaling up to rebalance any new data. Resulting in better storage efficiency, performance, and improved scalability.
