The PowerVault ME5 array has several integrations and touchpoints with the VMware vSphere ecosystem. Like the vSphere Web Client plug-in, some are more visible than others, such as the VAAI primitives in the firmware. However, a clear understanding of the functionality and benefits they provide is vital to efficient virtual-environment design.
These integrations and touchpoints include VMware vStorage APIs for Array Integration (VAAI) and VMware Storage I/O Control (SIOC).
