OS NEXUS makes next generation storage products to meet the needs of small, medium, and enterprise businesses which need high-performance, reliable, and cost effective storage cloud, server virtualization, and disk-to-disk backup solutions.

The company's flagship product, QuantaStor, is an iSCSI / FC / NFS storage system platform built from the ground up to be easy to use, low cost, and scalable. The QuantaStor Storage Appliance OS enables you to convert commodity 64bit servers into an enterprise grade storage system quickly and easily, and our QuantaStor E Series storage systems provide you with a turn key solution for your project.

Beyond the advanced iSCSI / FC storage system capabilities QuantaStor has a number of unique features including multi-tenancy via our 'private storage cloud' feature which enables administrators to delegate storage and its management to end users in their private storage cloud(s). This capability is key to supporting the multi-tenant environments deployed by cloud service providers and large organizations. With multi-tenancy and our advanced RBAC model QuantaStor is enabling administrators with powerful new tools for storage automation and delegation of common storage management tasks.
