Architecture and Technology

SoftNAS runs as a Linux®-based, 64-bit CentOS redistribution guest OS treated as a VM in a virtual server environment. In many use cases, storage devices are attached to the physical hardware layer, then presented to SoftNAS as a VM running Linux.

SoftNAS operates on an industry-standard Linux platform and uses a derivative of the Zettabyte File System® (ZFS), an open-source project originally released on OpenSolaris® by Sun Microsystems, Inc. This makes SoftNAS able to leverage many ZFS features and add layers of functionality for NAS solutions in virtual computing and cloud computing.

An Apache webserver provides robust, secure access along with Secure Shell® (SSH). Storage is accessible via TCP/IP protocols including NFS v3, NFS v4, SMB/CIFS (Microsoft® Windows File Shares), and iSCSI.  Also integrated into SoftNAS is Apache NiFi technology, providing powerful and scalable directed graphs of data routing, transformation, and system mediation logic.

SoftNAS is packaged with a primary administration interface called SoftNAS StorageCenter™, which provides commercial-grade storage administration and management functionalities for businesses of all sizes.

Use Cases

On-premises to Cloud Backup

With SoftNAS SnapReplicate™, easily replicate and backup your data from your VMware data center to the AWS, Microsoft Azure, or CenturyLink Cloud public clouds. Eliminate physical backup tape required by business compliance and archive data in inexpensive S3 object storage or send to cold storage like AWS Glacier for long-term storage.

Cross-cloud Data Migration

Server migrations can be complex, time-consuming, and error-prone. SoftNAS seamlessly replicates data across AWS, Microsoft Azure, CenturyLink Cloud, and VMware vSphere for easy cross-cloud data migration. Your data stays free to migrate, never locked down.

Business Continuity and Disaster Recovery

Easy-to-configure High-Availability (HA) with automatic failover and a 99.999% guaranteed uptime make SoftNAS a natural choice for your Disaster Recovery. Ensure business continuity in today’s 24x7x365 always-on business climate.

Faster Backup and Archival

As a business’ data grows, the backup window can become unmanageable and tie up precious network resources during business hours. SoftNAS local disk-based caching reduces the backup window by streaming data in the background for better WAN optimization.


Dev/Test Environments

Use SoftNAS to stand up test environments for agile development. Instant writable SnapClones allow regression testing of production data for more accurate testing throughout continuous delivery cycles. Leverage the agility of SoftNAS to change the storage performance and capacity profile at any time as you move from test to production.

New Applications and Proofs of Concept

Need the quickest way to stand up storage infrastructure for a new application or proof of concept project without any storage hardware? As a virtual storage appliance on AWS, Azure and CenturyLink Cloud or for VMware for on-premises projects, you can use SoftNAS to create your storage infrastructure in minutes. Don’t wait for traditional slow procurement processes to get your job done; get started immediately.

Extend the Life of Legacy SAN or Existing Storage Hardware

It’s no secret the maintenance renewal costs for legacy SANs are just as much, if not more than replacing your entire datacenter infrastructure. With hardware-neutral SoftNAS, extend the life of your existing storage resources and maximize your budget. Use SoftNAS to provide a rich enterprise-class set of features and leverage your existing SAN for the data store.

Get high-speed, reliable cloud storage at affordable prices.
