Infrastructure resilience for always-on operations

Nutanix offers a natively integrated solution for data protection and continuous availability at VM granularity. A robust system design provides rapid fault detection, isolation and recovery to ensure an always-on operation with an affordable range of options to meet the recovery point objectives (RPO) and recovery time objectives (RTO) for different applications.

AHV: A Virtualization Solution for the Enterprise Cloud

Hypervisor software licensing can be a significant portion of the IT infrastructure spend. Are you getting value from that spend? Nutanix AHV is an enterprise-ready hypervisor included at no additional cost with every Nutanix node.

Backup

Enterprise-grade backups with single pane of glass management provide the ultimate simplicity in management, while seamless backups of data to public cloud services provide high availability.

Cloud Connect

Built-in Hybrid Cloud

Get seamless, low cost VM-centric backups of data to public cloud services such as AWS and Microsoft Azure without third-party software.

WAN Optimized

Data transfer to the public cloud is WAN optimized, reducing the storage footprint and networking bandwidth by over 75%.

Simple Operations

Backup to and recover from the cloud with just a few clicks – view VM snapshots stored in the cloud and easily choose specific snapshots to recover.

Cloud Connect for AWS

A live Nutanix cluster runs on EC2 instances using the Elastic Block Store for metadata and S3 storage for backups, with support for Amazon Virtual Private Cloud (VPC).

Cloud Connect for Azure

Nutanix software runs on Azure Compute and storage is from Azure Page Blob, with support for Azure Virtual Network (VNET).

Converged Local Backups

Unlimited, Enterprise-grade Backups

VM-centric snapshots and integrated workflows with single pane of glass management deliver RPO in minutes.

Intelligent Disk-balancing

In heterogeneous clusters, Nutanix disk-balancing ensures that the data stored on nodes is proportional to the node storage capacity, increasing the effective storage available for snapshots.

Uncompromised Performance

Nutanix Time Stream’s redirect-on-write algorithm, VM-centric snapshots and file-level recovery provide optimum operational efficiency.

Simple Operations

Create virtual copies of data and roll back state with a single click.

Self-service File Recovery

End users can recover independent files inside a VM without having to recover the entire VM and without administrator intervention.

Near Unlimited Scalability

Seamlessly add Nutanix hyperconverged appliances to existing clusters to support nearly unlimited retention of snapshots and fast recovery.

Advanced Capabilities

Remote Backups

Integrated workflows simplify remote backups and one-click recovery.

Customized Scheduling

VMs can be backed up or asynchronously replicated to another customer owned datacenter based on a user-defined schedule.

WAN Optimized

During replication, data is compressed and replicated at the sub-block level for maximum efficiency and lower WAN bandwidth consumption.

Flexible Replication Topologies

Replication topologies are flexible and bi-directional, enabling one-to-one, one-to-many and many-to-many (e.g., hub-and-spoke, full-mesh) deployments

Disaster Recovery

Leverage integrated recovery and replication capabilities to meet the recovery time objectives (RTO) and recovery point objectives (RPO) of different applications. A simplified view of all local and remote snapshots allows administrators to restore state at VM granularity from a snapshot with a single click, or to failover to a secondary datacenter seamlessly.

Metro Availability

Continuous Availability

Synchronous replication ensures continuous availability of data and business-critical applications during disasters and planned maintenance.

One-click Failover

Simple and intuitive management that can be set up with a few simple steps, and failover that can be initiated with a single click.

Flexible Configuration Support

Supports heterogeneous clusters, and asymmetric hardware setups and storage policies across sites with existing infrastructure.

Bi-directional Replication

Metro Availability can be set up bi-directionally between two sites connected over a metro area network with a round trip latency of less than five milliseconds.

Non-disruptive Migrations

Virtualization teams can non-disruptively migrate virtual machines between sites, providing continuous data protection with zero (RPO) and near zero (RTO).

Resiliency

The Nutanix platform is fault resistant, with no single point of failure and no bottlenecks. A shared-nothing architecture – where all data, metadata and services are distributed to all nodes within the cluster – is built to detect, isolate and recover from failures anywhere in the system for an always-on operation.

Availability Domains

Intelligent Data Placement

Intelligent data placement across different physical domains (e.g., separate racks or power sources) protects against appliance and rack failures.

Robust Protection

Availability domains allow Nutanix clusters to survive the failure of multiple servers in a physical enclosure without loss to data or service, providing greater system-level resilience without increasing storage capacity.

100% Software-defined Flexibility

Administrators can configure and manage availability domains at the storage container level in clusters with five or more nodes.

Tunable Redundancy

User-defined Resilience

Administrators can configure data redundancy based on application SLAs and the criticality of the data set, with a replication factor (RF) of two or three.

Automatic Data Reconstruction

If a node fails, data is automatically read from other nodes. If the node does not come back online, all data on the affected node is automatically reconstructed to ensure full redundancy and data protection.

Synchronous Replication

Data is written to a VM’s local node and is synchronously replicated to one or more other nodes in the cluster, ensuring that all data exists in at least two independent locations and remains highly available.

Data Path Redundancy

High Availability During Controller VM Unavailability

Multiple copies of data ensure 100% data availability in the event that a Nutanix Controller VM is unavailable due to failure or maintenance.

Transparent Failover

If the Nutanix Controller VM becomes unavailable, Nutanix auto-pathing automatically re-routes requests to a healthy Controller VM running on another node in the cluster.

Fault-tolerant Architecture

Every node in a Nutanix cluster has access to all replicas so that I/O requests can be serviced immediately by any node, providing N-way, fully fault-tolerant failover for all VMs in the cluster.

Data Integrity Checks

Detection and Repair of Silent Data Corruption

The system scans data in the background and checks against checksums in the metadata store. If it detects an error, it will overwrite the bad data with the good copy.

Automatic Integrity Checks

On every read, a checksum is computed for the data being read and compared with the stored checksum. In the case of an inconsistency, the error is corrected.

Automatic Isolation and Recovery

If a drive fails, the system automatically runs a scan and replicates any data that is not redundant. During the failure and recovery process, both data and access to data are preserved.

Ecosystem Integration

Nutanix hyperconverged solutions integrate with popular offload capabilities, including VMware API for Array Integration (VAAI) and Microsoft Offloaded Data Transfer (ODX) to create clones in a matter of seconds with minimal overhead.

Support for vStorage API for Data Protection (VADP) and application-level consistent snapshots through Volume Shadow Services (VSS) provide full integration with third-party tools such as Symantec NetBackup, Veeam, Commvault and VMware SRM.

Integration with Commvault IntelliSnap delivers Commvault backup capabilities with enterprise grade storage features from Nutanix for a highly efficient backup solution.
