Nutanix AOS Storage (often referenced simply as “AOS Storage” inside Nutanix Cloud Infrastructure (NCI)) is a distributed, software-defined storage layer for hyperconverged infrastructure (HCI). It aggregates local disks across nodes into a single storage fabric intended to reduce reliance on traditional SAN/NAS for many virtualization and cloud workloads. Nutanix describes AOS Storage as providing linear scale-out, automated data placement/tiering, snapshot/replication-based data protection, and policy-based management through the Prism interface.
On the official product page, Nutanix characterizes AOS Storage as central to its cloud platform offering and positions it as an option for replacing traditional SAN and NAS in many environments with a scale-out, automated storage fabric. Key feature themes include data locality, intelligent tiering, snapshot efficiency, and self-healing capabilities.
