Summary
Single-Layer
Dual-Layer
Details
There are two main VxFlex OS components to consider:
- Storage Data Server (SDS) that is used to present storage volumes
- Storage Data Client (SDC) that is used to access storage volumes that are presented

Therefore VxFlex OS can be setup in two ways:
1. By installing both the SDS and the SDC component on the same server, creating a hyper-converged single-layer configuration.
2. By installing the SDS and SDC component on separate servers, creating a traditional dual-layer configuration.

The flexibility of the VxFlex OS platform allows the two configurations to be mixed within the same environment.
