QuantaStor is a unified file, block and object Software Defined Storage platform (iSCSI/FC/NFS/CIFS/S3/SWIFT) with grid technology that enables one to combine QuantaStor servers together within and across sites into a "Storage Grid". QuantaStor is a Linux based operating system and has been certified for use with all major servers including those from Cisco, DellEMC, HPE, Intel, Lenovo, Supermicro, and Western Digital. Once QuantaStor is bare-metal installed on a server, it may be combined with other QuantaStor servers to form a storage grid. Storage grids may scale to in excess of 100PB of storage and over 64 storage systems.

How is it unique from other SDS and storage systems?

QuantaStor is unique in a number of ways, specifically:

  • Storage Grid Management Technology
    • Enables companies to start small and grow hybrid-cloud environments to hyper-scale with ease. Grids can contain a heterogeneous mix of hardware from different vendors and may include QuantaStor Virtual Storage Systems.
  • Ease of Use
    • Strong focus on user experience which makes the QuantaStor web management interface easily understood and effective for IT generalists. OSNEXUS was founded by former EMC, Brocade, and Veritas Software engineers with a focus on eliminating the complexity found in traditional SAN/NAS systems.
  • Supports Open Standards
    • QuantaStor integrates with open storage technologies (Ceph, ZFS). OSNEXUS contributes to an supports OSS development and views the open filesystems as more reliable and better supported for the long term than proprietary alternatives which create data life-cycle risks for users.
  • Security Focus
    • QuantaStor is compliant to NIST 800-53, HIPAA, and CJIS standards and FIPS-140-2 Level 1 certified edition will be available in 2019. QuantaStor has an advanced Role-Based-Access-Control system and multi-tenancy features which provide further control and ability for organizations to delegate specific limited management access to IT administrators and users.
