Details
VxFlex OS supports both single-layer (hyper-converged) and dual-layer architectures, as well as a mix of both. This flexibility allows the platforms Storage Data Servers (SDSs) to present storage volumes to servers that have the Storage Data Client (SDC) component installed.

Storage+Compute: Existing VxFlex OS clusters can be expanded by adding additional VxFlex OS nodes that have both SDS and SDC components installed, which adds additional compute and storage resources to the shared pool.

Compute-only: Existing VxFlex OS clusters can be expanded by adding additional VxFlex OS nodes that only have the SDC component installed, which adds additional compute resources to the shared pool.

Storage-only: Existing VxFlex OS clusters can be expanded by adding additional VxFlex OS nodes that only have the SDS component installed, which adds additional storage resources to the shared pool.
