Nutanix Unified Storage Fundamentals and Architecture

What the exam tests

This domain checks whether you can explain how Nutanix Unified Storage combines Files, Objects, and Volumes on the Nutanix Cloud Platform, and how those services inherit AOS resilience. Expect questions on the Distributed Storage Fabric, Prism Element versus Prism Central, storage containers, and the fact that unified storage is software-defined rather than a separate silo.

Core architecture

  • Unified Storage runs on AHV clusters and uses the Distributed Storage Fabric for data placement, replication, and tiering.
  • Files presents SMB and NFS through File Server VMs. Objects exposes an S3-compatible endpoint. Volumes presents block LUNs over iSCSI.
  • Prism Element manages a single cluster. Prism Central provides multi-cluster management and RBAC.
  • Replication factor and storage policies are set at the container or volume group level, not by the client protocol.
  • Platform services such as snapshots, compression, deduplication, and encryption remain available regardless of protocol.

Worked example

A team wants one platform for SMB shares, an S3 backup target, and an iSCSI datastore for a physical server. The design is not three storage arrays. Deploy a Nutanix cluster, create a storage container, add Files for SMB, Objects for S3 buckets, and a Volume Group exposed through Volumes. The Distributed Storage Fabric provides resilience; each service adds its own access layer.

Traps

Do not treat Files, Objects, and Volumes as separate clusters by default. Do not assume Prism Element and Prism Central are interchangeable for every task. Do not confuse a storage container with a share or bucket. Do not forget that protocol services consume cluster IP addresses and capacity.

Key points

  • Unified Storage is a software-defined set of services on AOS.
  • Files uses FSVMs; Objects uses an S3 endpoint; Volumes uses iSCSI targets.
  • Prism Element is cluster-scoped; Prism Central is multi-cluster.
  • DSF supplies replication and data services beneath all three protocols.
  • Design capacity and IP planning before deploying services.
