What if you could take advantage of the unlimited flexibility offered by an Azure cloud hosted infrastructure without changing your applications or your data?  Would you consider a move that can keep up with your business, as needs change and your demands grow, without the strain of rearchitecting your own capital intensive data centers?  Consider the flexibility and scale of Microsoft Azure on-demand resources, that no single organization could possibly afford, that allows you to tap into virtually unlimited adaptability… anywhere in the world!

IT organizations need the freedom to make the best choices for their business. Demands on enterprise storage capacities continue to grow at an increasing rate. Access to storing more data and enabling more applications and users, regardless of access requirements, are essential. With ultra-easy consumption, pay-as-you-grow pricing and no architectural limits on growth, the appeal of the consumption model of public cloud is rising.

SoftNAS Cloud® is a software only enterprise storage virtual appliance solution that can replace traditional on-premise storage options for applications that typically require NFS, SMB/CIFS/SMB, iSCSI, and Apple File Protocol (AFP). Microsoft has partnered with SoftNAS to enable an easy transition to Azure for customers that need storage capacities ranging from terabytes to many petabytes.

How Does SoftNAS Cloud Work?

Unlike traditional storage that you pick from a list of SKUs and then wait for it to arrive, SoftNAS Cloud running on Azure, takes less than an hour to configure. There are four fundamental steps that all occur via the Azure Portal:

  • Creating the Virtual Storage Appliance – The Azure search function locates the SoftNAS Cloud image and then walks you through selecting an “instance type” for the virtual controller. Options instantly show up on the workflow in the portal for picking an appropriate compute capacity for loading the SoftNAS Cloud image. Azure instance types provide the vital physical ingredients that allow different degrees of performance like RAM and local SSD for caching, networking, and CPU. Here’s a video for details.

  • Attaching the Storage Account – Using the flexible options for storage performance and capacity types available on Azure, users can attach the appropriate media provisioned from an Azure storage account. The options range from all flash to cool blob (object) storage types. See more on using Azure block storage or for adding Blob (object) storage.
    Attaching the storage account
  • High Availability – Using Azure Availability Sets, SoftNAS Cloud enables two instances that communicate via a virtual IP address to the workloads. The Availability Set architecture ensures that the two virtual machines running SoftNAS Cloud are not part of the same affinity group. For more information on setting up high availability, please see this video.

  • Final steps: Confirm the configuration, purchase and push the setup to deployment. In less than an hour, the NAS storage solution has been created and ready to use. Configuring the volumes
    and LUNs occurs via the SoftNAS StorageCenter™ web console. Here’s a video for an overview of the SoftNAS StorageCenter and more information on configuring pools and volumes.

SoftNAS Cloud utilizes the Azure block and/or object storage accounts as a storage pool much like traditional storage systems use disk drives.

SoftNAS and Azure InfrastructureSoftNAS Cloud and Azure make a great combination for increasing the native Azure file services capacity beyond the 5TB limit available today. Because SoftNAS Cloud is a software only means of creating the storage system, customers have the flexibility to choose from a wide range of Azure compute instances to meet varying performance demands. SoftNAS Cloud leverages these combinations to provide flexible cost and performance storage solutions that are often difficult or impossible to obtain using conventional on-premises options. If you are unsure of your future demands, you simply add-on capacity as your needs change.

Azure Options

Thinking you might be taking a step backwards by shifting your storage and applications to the cloud? SoftNAS Cloud includes all the enterprise features expected from an on-premises network storage solution. This includes these advanced capabilities:

Data Protection

  • High availability for a No Downtime Guarantee™
  • Copy on write file system
  • On-disk and in-flight encryption for 360-degree™ protection
  • AD, AAD, and LDAP integration

Lifecycle Management

  • Instance writeable clones Snapshotting
  • Replication

Data Efficiency Services

  • Deduplication
  • Compression
    … both for better cloud storage cost effectiveness


  • NFS, SMB, CIFS/SMB, AFP, and iSCSI protocols Hybrid, on-premises or Azure cloud hosted
  • Scales from terabytes to petabytes

If Azure already provides storage, why do I need SoftNAS Cloud?

Indeed, Azure provides various storage options, but these may not help fill all the needs customers have for making the shift to a public cloud hosted infrastructure. Here are some reasons why and how SoftNAS Cloud complements these Azure offerings:

File Services

  • CIFS/SMB only protocol
  • No AD integration
  • 5TB limit

Using the options below, SoftNAS Cloud overcomes capacity limits, adds all file protocols, adds full
AD/AAD/LDAP user access controls, consumption efficiency and full featured data services.

Standard Storage

  • SSD or Hard disk based storage
  • Block only 2 – 40TB capacity

Leverages the block storage to present NAS file protocols.
Accelerates performance and improves data efficiency.

Cool & Hot Block Blob Storage

  • Object storage only
  • Up to 500TB per storage account

Leverages the object storage to present NAS file protocols and expands the Azure capacity to petabytes by aggregating multiple storage accounts. Accelerates performance and improves data efficiency.

Ideal Uses Cases

The use cases for software-based virtual storage appliances hosted on Azure span many segments. At the end of the day, all computing resources require and use storage. For unstructured data with ever increasing file sizes, examples of ideal uses include:

  • Archive and record retention
  • User file sharing
  • Video/media storage
  • User file directories
  • Source code repository
  • Medical records
  • Legal documents
  • Energy Industry data
  • Big Data
  • Genomics

Hybrid storage for extending on-premises capacities to Azure using standard mountable NAS protocol connected over a VPN WAN connection is also a common use case. Use the existing data center infrastructure and expand to an Azure hosted storage option with ease. SoftNAS Cloud provides on premises to cloud capabilities for replication or expansion.

When to Think About Using

In summary, SoftNAS Cloud fits customer needs for the following scenarios when considering Azure: 

  • SoftNAS Cloud extends native capabilities of Azure for CIFS/SMB, NFS, AFP, iSCSI storage. 
  • For use cases where applications need large file capacity (up to many petabytes) and need an easy way to move them to Azure. 
  • You are ready to move from traditional on-premises storage to an elastic public model but don’t want the expense of re-engineering the data services.
  • Need a flexible storage model that can service different roles ranging from high performance all flash to capacity oriented Cool Blob.

How to Get Started:

You can get started with SoftNAS Cloud on Azure in multiple ways via the Azure Marketplace:

Get started with SotfNAS Cloud


  1. Free Azure Test Drive: Get started in under 10 minutes using the Azure Test Drive. This option allows you to quickly try SoftNAS Cloud without having to install or configure anything. The SoftNAS Cloud instance loads automatically, connects the Azure storage account and pre-provisions multiple storage volumes/LUN using NFS, CIFS/SMB, and iSCSI. No Credit card or Azure Subscription required but the environment is available for 1 hour from the time you enter the test drive.  
  2. Free 30-Day Trial:  You can also try the SoftNAS 30 day Free-Trial on your Azure subscription.  This will allow you to install, configure and use SoftNAS Cloud as if you were running in a production environment. This allows you to explore the product for multiple weeks; but, it will require an Azure subscription
  3. Purchase: You can purchase SoftNAS Cloud on the Azure Marketplace. We offer an Express Edition for 1TB of capacity, a Standard Edition for 20TB of capacity. Discounted larger deployments up to many petabytes, are available via a BYOL (Bring Your Own License) obtained by contacting the SoftNAS Sales team or an authorized reselling partner.
