Single-Layer: Pivot3 Acuity is meant to be used as a storage platform as well as a compute platform at the same time. This effectively means that applications, hypervisor and storage software are all running on top of the same server hardware (=single infrastructure layer).
Pivot3 Acuity can also serve in a dual-layer model by providing storage to non-Acuity hypervisor hosts (Please view the compute-only scale-out option for more information).
