Just like traditional hardware, the Nasuni Filer provides unified storage through standard protocols and access control through existing authentication systems. Unlike traditional storage, Nasuni’s next-generation storage controller never needs to be backed up or replicated and never runs out of capacity.
Much more than just a “cloud gateway”, the Filer is the on-premises component of the Nasuni solution that is responsible for everything from snapshots to auditing to anti-virus. Combining the best aspects of cloud storage with the comfort of traditional storage appliances, the Nasuni Filer delivers a whole new enterprise file storage experience.
In your network, the Nasuni Filer looks and feels just like a traditional storage controller – ensuring that end-users and applications have the exact same experience on a Nasuni Filer as they would on an array from the traditional vendors. Specifically, the Nasuni Filer can be used to handle both NAS and SAN workloads. Nasuni Filers are used for storage applications from 3D modeling to litigation support to file services and even server virtualization. Nasuni was the first Cloud-integrated Storage (CiS) vendor to offer both NAS and SAN capability and is the only vendor to offer integrated mobile file access over HTTPS.
The on-premises Nasuni Filer delivers local storage performance with a minimal footprint. Even though customers store hundreds of TBs with Nasuni Enterprise File Services, each Filer only caches the most important and most frequently accessed files. Using sophisticated and proprietary caching algorithms, Nasuni customers achieve local performance with only a small percentage of the dataset in their local storage. This means less hardware and lower costs for customers.
UniFS® is Nasuni’s file system that bridges NAS and SAN access to the scalable object storage of the cloud. It is the only file system of its kind and can scale from hundreds to hundreds of billions of objects without any degradation of performance. Nasuni customers already store millions of snapshots in the cloud and billions of files representing petabytes of data.
This patented capability allows Nasuni to conquer the limits of traditional snapshots and eliminate additional backup requirements. Unlike hardware-based systems where snapshots are a limited resource, Nasuni systems can contain millions of snapshots replicated to multiple datacenters offsite using cloud storage. Using Nasuni, files and blocks from previous snapshots can be recovered in a matter of minutes – regardless of whether the snapshot is from three days or three years ago.
The family of Nasuni Filers scale to deliver the optimal solution in every office – ranging from the corporate data center all the way to remote and branch locations. Some locations will need the performance of SSD storage and large amounts of RAM while other locations may need lots of local storage and can sacrifice raw speed. Varying needs of performance, local storage, high availability and price require a flexible family of Filers. Nasuni’s appliances offer a variety of versions and options that allows customers to work with Nasuni engineers to build the optimal storage controller solution for their unique price and performance needs.
Nasuni Filers truly are software defined storage – the same code in hardware appliances is available as a virtual machine. Deployments in the field contain a mix of virtual machines (both in the datacenter and the cloud) with every flavor of hardware available. Regardless of form factor, all Nasuni Filers will work together, sharing the same global dataset.
Critical functions provided by the Filer include:
Integrated WAN optimization enables Nasuni Filers to be deployed all over the world – even in offices and locations with limited and inconsistent connectivity. A perpetually cloud-connected storage system could saturate your network – especially if the local storage appliances frequently need to talk to one another. Not so with Nasuni.
Nasuni’s storage controllers communicate directly with the cloud – never with one another, ensuring they are leveraging the unlimited bandwidth of the cloud and not the limited connectivity of your offices. Before any bits are transmitted, data is chunked, compressed and deduplicated against the global file system so that nothing is sent twice.
All data stored with Nasuni is encrypted both in flight and at rest in the cloud using customer controlled keys. This simple design principle means that neither Nasuni nor a cloud storage provider ever has access to customer data. Furthermore, it transforms cloud storage from an unprotected pool of shared storage into a secure repository that even the most hardened security teams approve of.
Using established security protocols, the Nasuni Filer encrypts all data before transmission using military-grade AES-256 encryption. Nasuni further employs the open-source and highly efficient OpenPGP standard for key management – a standard that supports an extensive and thorough review process in the public domain. Using this publicly available and time-tested standard ensures customer data will always be available.
In addition to OpenPGP and customer controlled keys, Nasuni takes data security several steps further:
