Server Impact On Server Storage: Key Assumptions

Key features in vSphere such as High Availability and vMotion are enabled by shared storage between hosts. For customers who will not be implementing
physical a shared storage solution, a new software solution from VMware, the vSphere Storage Appliance (VSA), transforms cheaper internal host storage
(up to 3 hosts) into a single shared storage resource.

Ideal for customers planning to virtualize smaller environments with vSphere Essentials+.
