What is Azure NetApp Files?

Azure NetApp Files is a fully managed file storage service designed for enterprise workloads that require high throughput and low latency. It supports NFS (v3 and v4.1), SMB, and dual-protocol access, making it ideal for a wide range of applications, including SAP, databases, VDI, and high-performance computing (HPC).

Unlike traditional cloud storage services, ANF is natively embedded in Azure, meaning it doesn’t require any additional setup or third-party integrations. Users can provision volumes directly from the Azure portal, CLI, or API, and integrate them seamlessly with their existing Azure resources.

Key Features

  1. Performance Tiers

ANF offers three performance tiers to suit different workload requirements:
– Standard: Suitable for general-purpose file shares and dev/test environments.
– Premium: Ideal for latency-sensitive applications like databases and analytics.
– Ultra: Designed for the most demanding workloads, such as HPC and large-scale SAP deployments.
Users can dynamically change performance tiers without downtime, offering flexibility and cost optimization.

  1. High Availability and Durability

ANF provides 99.99% availability SLA and ensures data durability through redundant storage architecture.

  1. Security and Compliance

Security is a top priority with ANF. It supports:
– Encryption at rest and in transit
– Active Directory integration
– Role-based access control (RBAC)
– VNet integration and private endpoints

  1. Snapshot and Backup

ANF supports instant snapshots for data protection and rapid recovery. These snapshots are space-efficient and can be used for cloning environments or restoring data without impacting performance.

Benefits of Using Azure NetApp Files

  1. Simplified Management

As a fully managed service, ANF eliminates the need for manual storage provisioning, patching, and maintenance. This allows IT teams to focus on strategic initiatives rather than infrastructure management.

  1. Scalability

ANF can scale from a few gigabytes to multiple petabytes, supporting both vertical and horizontal scaling. This makes it ideal for growing businesses and dynamic workloads.

  1. Consistent Performance

With guaranteed throughput and low latency, ANF ensures consistent performance for critical applications, even under heavy load.

Network Architecture and Access

Azure NetApp Files volumes are deployed within a dedicated subnet known as a delegated subnet inside your Azure Virtual Network (VNet). This specialized subnet is exclusively reserved for Azure NetApp Files, ensuring a secure and isolated environment with no direct internet connectivity.

Access to these volumes is highly flexible:
– Within Azure, you can connect to ANF volumes using VNet peering, enabling seamless communication across different VNets.
– From on-premises environments, access is facilitated through a Virtual Network Gateway, using either ExpressRoute or a VPN Gateway for secure, high-performance connectivity.
This architecture ensures that your data remains protected within a controlled network boundary while still being accessible to both cloud-native and hybrid workloads.

Common Use Cases

  1. SAP on Azure

ANF is certified for SAP HANA and supports high IOPS and throughput requirements, making it a preferred choice for SAP workloads.

  1. VDI (Virtual Desktop Infrastructure)

With its low-latency and high-throughput capabilities, ANF supports fast user profile loading and application responsiveness in VDI environments.

  1. High-Performance Computing

ANF’s Ultra tier is optimized for compute-intensive workloads like genomics, oil and gas simulations, and financial modeling.

Getting Started

To start using Azure NetApp Files:
1. Register the ANF resource provider in your Azure subscription.
2. Create a NetApp account and capacity pool.
3. Provision a volume with the desired protocol and performance tier.
4. Mount the volume to your virtual machines or services.
