Storage+Compute: Existing Pivot3 Acuity clusters can be expanded by adding additional X5-Series nodes, which adds additional compute and storage resources to the shared pool.

Compute-only: Because Pivot3 Acuity leverages a common block protocol (iSCSI), storage can be presented to hypervisor hosts not participating in the Pivot3 Acuity storage cluster, as long as these hosts are connected to the storage iSCSI network. This is also beneficial to migrations, since it allows for online storage vMotions between Pivot3 Acuity and non-Pivot3 Acuity storage platforms.

Storage-only: With the release of Acuity 10.6.1 Pivot3 introduces Storage appliances next to its HCI appliances. The Storage appliances have minimal CPU and Memory resources on board and only take part in the storage cluster so they can contribute to the shared storage pool of the HCI appliances. They do not take part in the hypervisor (compute) cluster, so no VMware vSphere licenses are required.
