NexuStorage’s Nexfs software serves block and file data from an object-backing store using sub-file chunking to reduce data movement and help data tiering, and claims great tier-one storage cost savings and good performance.

It has devised Nextassert software to do this without traditional data mapping indices, relational or NoSQL databases, manifests, stub files or symlinks. The company is a nine-month-old founder-funded startup based in New Zealand, and briefed a virtual IT Press Tour on its technology

Founder Glen Olsen, an ex-product manager at DataCore-acquired Caringo, said his Nexfs technology removes the gap between the worlds of file and block storage on the one hand and object storage on the other, with the object storage either on-premises or in the public cloud. Nexfs delivers, he said, a unified, intelligent, cost-effective, massively scalable, data-lifecycle-enabled, storage system that can provide an up to 95 per cent reduction in primary storage capacity.

The software runs on industry-standard servers and is available as a no-charge, downloadable Community Edition, with subscription-based, SLA-backed support coming soon.

Nexfs


Nexfs is a file system. It splits files into chunks of between 1MB and 8MB in size and stores these chunks on three tiers of media: fast SSDs, slower SATA disk drives, and slower-still object storage. Nexfs presents data through either block or file interfaces, with iSCSI, NFS and SMB/CIFS interfaces supported. There is no direct access to the underlying object storage, although an open source web proxy providing S3 access is on the roadmap.
