Enterprise data storage as an on-demand service

The Nutanix Enterprise Cloud Platform eliminates the need for traditional SAN and NAS solutions by employing a highly distributed software architecture. It delivers a rich set of software-defined services that are entirely VM-centric, including snapshots, high availability, disaster recovery, deduplication and more.

Performance Acceleration

Nutanix web-scale solutions employ a variety of advanced mechanisms to drive the highest possible performance for a wide range of virtualized workloads. Powerful acceleration capabilities such as caching, automatic data tiering and data locality speed storage performance. Server-attached flash storage is used both as a high-performance read cache, as well as a persistent data tier in a Nutanix hyperconverged system.

Intelligent Distributed Data Tiering

Automatic Optimization

Application and user data is automatically placed in the optimal storage tier – flash or HDD – to yield the fastest performance and optimize capacity in the cluster.

Hot Data

The most frequently accessed data (“hot” data) is placed in the SSD or cache tier for near instantaneous access by VMs.

Cold Data

As data becomes “cold,’”it is demoted into the higher capacity HDD tier for more efficient storage, so that SSD and cache capacity remains available for new “hot” data.

Data Placement Management

MapReduce technology manages data placement as a distributed, background process to ensure negligible impact to real-time performance.

Data Localization

Localized Write I/O

Data stays proximate to the VM and allows write I/O operations to be localized on that same node.

Continuous Analysis

Each Nutanix Controller VM (CVM) continually analyzes whether I/O requests are satisfied by storage resources local on that node, or from another node in the cluster.

Transparent Migration

If a VM migrates to another host for load balancing in an active migration scenario, hot data automatically follows the VM to maintain the highest performance.

Intelligent Migration

After a certain number of read requests made by a VM to a controller that resides on another node, Nutanix data localization moves the remote data to the local controller.

Data Localization Management

Data localization is managed as a MapReduce job to take full advantage of all cluster resources and not impact system performance.

Flexible Block Sizes

Range of I/O Sizes

End-to-end support for I/O sizes from 512 bytes up to 1 MB ensures optimal performance across a wide range of workloads and delivers application-tuned metadata efficiency.

Variable Lengths

Unlike traditional storage systems that break up incoming I/O requests into fixed 4KB chunks, Nutanix efficiently handles block sizes of variable length across the entire write path.

VM Flash Mode

Keep Data in Vdisks

For applications that require consistent, fast storage performance, data can be kept in vdisks in the cluster-wide SSD tier for highest performance regardless of data access.

Mix Workloads

VM Flash Mode provides the ability to mix IOPS-sensitive workloads with regular workloads in the same Nutanix cluster without creating resource silos.

Granular Control

Features can be enabled and controlled at VM or vdisk granularity, providing fine-grained control over storage performance in a hybrid cluster.

Capacity Optimization

Nutanix incorporates a wide range of storage optimization technologies that work in concert to make efficient use of available capacity for any workload. Deduplication and compression technologies are intelligent and adaptive to workload characteristics, eliminating the need for manual configuration and fine-tuning. Erasure coding offers deterministic capacity savings regardless of workload characteristics.


Performance Tier Deduplication

Removes duplicate data in the content cache (SSD and memory) to reduce the footprint of an application’s working set, enabling more working data to be managed in the content cache for better performance.

Capacity Tier Deduplication

Global, post-process MapReduce deduplication reduces repetitive data in the capacity tier to increase the effective storage capacity of a cluster.

Simplified Management

Easily configured and managed at vdisk granularity for fine-grained control.


Increase Capacity by up to 4x

Data compression can be enabled as an inline capability as data is written to the system, or post-process as a series of MapReduce jobs after the data has been written, eliminating any impact on write path performance.

Leverage All Resources

Unlike traditional architectures where compression operations run on one or two CPUs, Nutanix compression runs on each node in the cluster to leverage all system compute and memory resources.

Compress a Variety of Data Types

Nutanix uses the Snappy compression algorithm to compress a variety of data types more efficiently, and includes the option to compress data at the sub-block level for greater simplicity.

Erasure Coding with Nutanix EC-X

Resilience with Capacity Efficiency

A mathematical function is applied around a data set to calculate parity blocks, which can then be used to recover data in the event of a failure.

Optimized Performance

Nutanix systems switch between data replication for hot data and erasure coding for cold data based on I/O frequency to optimize performance and storage.

Nutanix EC-X

This patent-pending algorithm distributes coding and rebuilds across the entire cluster to reduce vulnerability windows in the event of failures, and maintains data locality.


Improve performance with distributed caching of VM data for linked clones, redirect-on-write snapshots and writeable clones at the granularity of a single VM.

Snapshots & Clones

Near Zero Performance Impact

Redirect-on-write snapshots and writeable clones at the VM level increase efficiency, while differential forever snapshots impose lower capacity overheads on the system.

Fine-grained Data Management

Unlike systems that snapshot data at a volume or LUN level, Nutanix snapshots and clones are performed for individual VMs for fine-grained data management and protection.

Easy Clone Creation

Create clones (writeable snapshots) of a base image in seconds, leveraging integration with popular offload capabilities, including the VMware API for Array Integration (VAAI), Microsoft Offloaded Data Transfer (ODX) and SMI-s.

Shadow Clones

Unique Nutanix Feature

Shadow Clones are a unique Nutanix feature that significantly improves performance by caching virtual machine data across a Nutanix cluster.

Ideal for Multi-reader Scenarios

Gain performance where there are multiple VMs reading a single source of data, or in VDI deployments with linked clones (e.g., Citrix MCS Master VM or VMware View replica disks).

vDisk Access Trend Monitoring

If read I/O requests originate from more than two remote Controller VMs (CVMs) and the local CVM, the vDisk is marked as immutable and cached locally, so read operations are satisfied by direct-attached storage resources.
