Recap: Hyper-Converged, Software-Driven Architecture10

Scale-Out Model on Hyper-Converged Solution

• Intelligence in software

• Single layer of compute,

networking and storage software

• Elastic Scaling

• Hardware agnosticSoftware

• Convergence of physical storage

on commodity x86 hardware

• Building block approach
