Nasuni
Nasuni is a privately held cloud storage company with headquarters in Boston, Massachusetts. It was founded in 2008, and has raised approximately $120M, with the last funding a $38M investment by Goldman Sachs.
The firm's storage software uses object storage, local file caching appliances, and the company's proprietary UniFS global file system to offer a hybrid cloud solution for Network Attached Storage. Nasuni integrates with public cloud storage platforms, such as Amazon Web Services and Microsoft Azure, and private cloud storage platforms such as IBM Cloud Object Storage and EMC Elastic Cloud Storage. Such storage platforms provide an object-based storage infrastructure, on top of which UniFS creates a complete versioned file system. The Nasuni platform stores customer data as a sequence of snapshots that include every version of every file. The firm has demonstrated the ability to store more than one billion objects in a single storage volume.
Nasuni Edge Appliances run on-premises to provide shared access to active files. These Appliances can be virtual, running on existing infrastructure, or physical, running on hardware offered by Nasuni. The appliances can also run in the cloud as a Microsoft Azure or Amazon EC2 virtual appliance. Hardware appliance choices include systems with solid-state drives.
Nasuni holds a number of patents for technologies that support the Nasuni enterprise file services platform, including:
- A cached file system that stores data and metadata in a cloud object store.
- A cloud service that coordinates management of file locks across multiple locations to enable collaboration without file conflict.
- A cloud service that coordinates the creation of versions of a shared volume across multiple locations.
- A versioned file system with fast restore.
- Cloud-native global file system with multi-site support using push classes.
- Network accessible file server.
