- Nutanix Cloud Infrastructure (NCI)
- Related: AHV, Nutanix Distributed Storage Fabric
The foundational software layer that pools compute and storage across cluster nodes and presents them as shared resources. AI deployments size GPU hosts, storage tiering, and network fabric on top of this distributed platform.
- AHV

The per-cluster management interface for configuration, health, and alerts. Operators use it for local GPU host settings, storage container policies, and cluster-level monitoring of AI infrastructure.
- Prism Central
- Related: Prism Element, Nutanix Categories
A multi-cluster management plane that aggregates Prism Elements and adds categories, policies, and centralized reporting. Multitenant AI environments rely on it for scoping, RBAC, and cross-cluster visibility.
- Nutanix Distributed Storage Fabric (DSF)
- Related: Storage Container, Nutanix Files
The software-defined storage layer that spreads data across all nodes with local SSD and HDD tiers. It supplies the throughput and resilience that training data pipelines and checkpoints depend on.
- Storage Container
- Related: Nutanix Distributed Storage Fabric, Erasure Coding
A logical storage grouping on DSF with its own policies for compression, deduplication, and replication factor. AI datasets are usually placed in containers tuned for high sequential read and low dedup overhead.
- Erasure Coding
- Related: Storage Container, Replication Factor
A data protection scheme that stores parity fragments instead of full replicas, trading some write cost for lower capacity overhead. Large immutable AI datasets often benefit from it compared with replica-based protection.
- Replication Factor
- Related: Erasure Coding, Nutanix Distributed Storage Fabric
The number of copies of each data extent that DSF maintains across nodes. Raising it improves durability for critical model artifacts but consumes capacity that could otherwise hold training data.
- Nutanix Objects
- Related: S3-Compatible Endpoint, Nutanix Files
An S3-compatible object store that runs on Nutanix infrastructure and scales across clusters. It backs data lakes, model artifact repositories, and bucket-based access for AI pipelines.
- S3-Compatible Endpoint
- Related: Nutanix Objects, Data Lake
An HTTP interface exposing bucket and object operations using the Amazon S3 API conventions. AI frameworks and tools point at this endpoint to read datasets and write checkpoints without code changes.
- Nutanix Files
- Related: Nutanix Objects, NFS Datastore
A scale-out file service providing SMB and NFS shares on the Nutanix platform. Shared NFS exports are common for multi-node training jobs that need a common dataset and checkpoint location.
- NFS Datastore
- Related: Nutanix Files, Persistent Volume
A storage mount presented over the Network File System protocol and registered as a datastore for virtualization or containers. It gives many GPU workers concurrent access to the same training corpus.
- Nutanix Database Service (NDB)
- Related: Database Clone, Nutanix Objects
A database lifecycle management service that provisions, clones, and patches database engines on Nutanix. AI applications that need relational or vector-capable databases use it for fast test and dev copies.
- Database Clone
- Related: Nutanix Database Service (NDB)
A space-efficient copy of a database created from a snapshot or gold image, often writable almost instantly. Teams use clones to refresh feature stores or evaluation datasets without duplicating storage.
- Data Lake
- Related: Nutanix Objects, S3-Compatible Endpoint
A centralized repository holding raw and processed data at scale, usually on object storage. AI teams land training corpora here before curation, labeling, and feature engineering.
- Nutanix Kubernetes Platform (NKP)
- Related: NVIDIA GPU Operator, Persistent Volume
Nutanix's curated Kubernetes distribution for deploying and managing clusters across on-premises and cloud environments. It hosts containerized inference services, notebooks, and ML operators.
- NVIDIA GPU Operator
- Related: Device Plugin, Nutanix Kubernetes Platform (NKP)
A Kubernetes operator that automates driver, container runtime, and device plugin installation on GPU nodes. It makes GPUs schedulable in NKP clusters without manual node configuration.
- Device Plugin
- Related: NVIDIA GPU Operator, GPU Scheduling
A Kubernetes extension that advertises a hardware resource such as a GPU to the scheduler. Pods request GPUs through resource limits, and the plugin handles allocation on the node.
- GPU Scheduling
- Related: Device Plugin, Node Affinity
The process of assigning pods or VMs to hosts with available GPU capacity based on requests, taints, and affinity rules. Correct configuration prevents contention and idle accelerators in shared clusters.
- Node Affinity
- Related: GPU Scheduling, Taint and Toleration
A scheduling rule that constrains which nodes a workload may run on, based on node labels. AI jobs use it to pin work to GPU models or to isolate tenants on dedicated hardware.
- Taint and Toleration
- Related: Node Affinity, GPU Scheduling
A paired mechanism where a node repels pods unless they explicitly tolerate its taint. Operators taint GPU nodes so only accelerator-consuming workloads land there, preserving scarce capacity.
- GPU Passthrough
- Related: vGPU, AHV
A configuration that gives a virtual machine direct, exclusive control of a physical GPU. It delivers near-native performance for training but prevents sharing that card with other VMs.
- vGPU
- Related: GPU Passthrough, MIG
A technology that partitions a physical GPU into virtual slices assigned to multiple virtual machines. It improves utilization for lighter inference or desktop workloads while isolating each consumer.
- MIG (Multi-Instance GPU)
- Related: vGPU, GPU Scheduling
A hardware partitioning feature on certain NVIDIA GPUs that splits one card into isolated instances with dedicated memory and compute. It suits small inference tasks that do not need a full accelerator.
- Nutanix GPT-in-a-Box
- Related: Nutanix Kubernetes Platform (NKP), Model Inference
A reference architecture and deployment model for running generative AI models and supporting services on Nutanix infrastructure. It bundles validated compute, storage, and software guidance for self-hosted inference.

- Related: Role-Based Access Control, Prism Central
Key-value metadata labels applied to VMs, clusters, or other entities for grouping. Policies and role assignments can target categories, enabling automated and tenant-scoped governance in AI environments.
- Role-Based Access Control (RBAC)
- Related: Nutanix Categories, Namespace Isolation
An access model that grants permissions to roles and assigns roles to users or groups. Multitenant AI platforms scope roles to projects or categories so tenants see only their own resources.
- Namespace Isolation
- Related: Resource Quota, Role-Based Access Control
Separating Kubernetes workloads into distinct namespaces with their own quotas, policies, and network rules. It prevents one team's training job from consuming another team's GPU or storage budget.
- Resource Quota
- Related: Namespace Isolation, GPU Scheduling
A Kubernetes limit on aggregate CPU, memory, GPU, or storage that a namespace may consume. Quotas keep a single AI team from monopolizing shared accelerator capacity.
- Encryption at Rest
- Related: Nutanix Objects, Storage Container
Protecting stored data by encrypting volumes or buckets so physical access to media does not expose content. It is a baseline control for regulated training data and model artifacts.
- Persistent Volume
- Related: NFS Datastore, Nutanix Kubernetes Platform (NKP)
A Kubernetes storage abstraction that outlives individual pods and binds to a backing datastore. Model caches and datasets mount as persistent volumes so restarted pods keep their data.
- Nutanix Cluster
- Related: Prism Element, Nutanix Distributed Storage Fabric
A set of nodes managed as a single unit that shares storage and compute resources. AI capacity planning starts at cluster granularity because GPU hosts and storage scale together.
- Lifecycle Management
- Related: NVIDIA GPU Operator, Nutanix Kubernetes Platform (NKP)
The practice of tracking versions and applying upgrades, patches, and retirement to infrastructure and software components. AI environments need coordinated updates across hypervisor, Kubernetes, drivers, and model servers.
