Storage Spaces Direct (S2D) is a function starting with Microsoft Windows Server 2016 to build a software-defined storage solution. The use of additional hardware storage is not necessary.
Storage Spaces Direct is the corresponding function that paves the way to high availability solutions on server basis. A common storage space is created - the so-called Storage Space - which extends over several storage media / data carriers. On this common storage space, storage units (volumes) are managed, which behave like local drives. This is all called "hyper-convergence" - the merging of different resources under one management.
When using Storage Spaces Direct, a central storage can be dispensed with, since the storage media of the connected servers are accessed here and the failure of components (e.g. in the event of an accident) is compensated for via the shared storage space. Even if two complete servers fail, the functionality of Storage Spaces Direct intercepts these failures and maintains operation.
- Building high availability without centralized storage
- No special hardware necessary - use of standard servers and Ethernet
- Full scalability when expanding the solution
- Flexibility in the use of hardware, since the solution works software-defined
