Nasuni: Next-gen Cloud-native File Storage

Andres Rodriguez, CEO
Unstructured file data is growing faster than ever, outpacing structured block data by a factor of 10. Businesses can’t keep up. “The traditional way of buying on-premises Network Attached Storage (NAS) for primary and archive storage; backing it up, and then duplicating the whole thing for disaster recovery (DR), doesn’t scale,” says Andres Rodriguez, CEO, Nasuni. During the dotcom era, when Rodriguez was the New York Times CTO, he got a firsthand look at the challenges in data storage, archiving and content preservation. Rodriguez found the answer to winning the file storage scalability battle in his third startup—Nasuni. By designing a global file system that could scale with cloud object storage and combining it with a consolidated set of NAS services, Rodriguez unlocked the cloud’s full potential through Nasuni’s cloud-scale enterprise file services solution. Hence why he named the company Nasuni - short for “NAS unified.”

The Nasuni platform enables enterprises to refresh aging NAS infrastructure, achieve new levels of cross-site collaboration, run analytics to extract more value from long-term file storage, and benefit from the new era of Internet-connected machines. At the heart of the platform is Nasuni UniFS. “This is world’s first global file system designed to “live” in the cloud. “This is where our unlimited scalability comes from,” adds the CEO. Nasuni offers unlimited primary NAS and archive storage capacity, backup, file access and collaboration, DR, and centralized management, all in one consolidated, pay-as-you-grow solution. “Nasuni typically saves up to 60 percent of the cost of traditional on-premises file storage infrastructure,” states Rodriguez. Because all files and metadata are stored in object stores, Nasuni inherits the scalability, durability, and geo-redundancy of the cloud.

The traditional file storage approach was to put all files into a file system that lives inside a big NAS array located on-premises. Nasuni turns this “device-first” model upside down with its new “cloud-first” approach. The firm uses on-premises caching appliances (virtual or physical) to provide high-performance access only to commonly used files using traditional NAS protocols.
Any file created by users on these edge appliances is automatically propagated to the cloud object store, where it is stored as the authoritative “gold copy” by Nasuni UniFS. The centralized control comes from the Nasuni Management Console, which enables administrators to manage edge appliances, volumes, and shares from a single web interface.

Furthermore, Nasuni’s Continuous Versioning feature eliminates the need for separate file backup infrastructure. Rodriguez explains, “Changes to files are continuously sent to the cloud where they are stored in a Write Once Read Many (WORM) model, with unlimited retention for both files and versions.” For customers of Nasuni, all it takes to recover any file or set of files is to restore the metadata stored in the cloud object store to a local edge appliance. This is true whether the file was deleted by a user, corrupted by an OS malfunction, or infected by WannaCry or CryptoLocker. This is why so many customers use Nasuni as a fast Ransomware fix. The built-in geo-redundancy of the cloud combined with the global reach of UniFS also means the days of building and maintaining expensive, dedicated disaster recovery sites are over.

Setting Nasuni apart from other vendors in the market, says Rodriguez, is that Nasuni is the first cloud-native solution that starts with the cloud, uses the object store as the gold master, and pushes files to the edge, which is much harder to engineer than competing solutions that use on-premises devices to store gold masters and simply use the cloud for backup. With Nasuni UniFS as the innovation behind a unified set of file services that offers unlimited capacity, improved recovery points and recovery times, global file access and collaboration, DR without the need for dedicated DR sites, and simple management—Nasuni is one of IT’s best new weapons in the battle for file storage scalability.
