What is QuantaStor?

Jump to: navigation, search

QuantaStor is a unified file, block and object Software Defined Storage platform (iSCSI/FC/NFS/CIFS/S3/SWIFT) designed from the ground up to scale-out and scale-up with ease. QuantaStor SDS is a Linux based OS which installs on all major server hardware converting bare-metal systems into a full-featured enterprise storage grid with up to 64 appliance nodes.

How is it unique from other SDS and storage systems?

QuantaStor is unique in a number of ways, specifically:

  • Grid management technology which enables companies to start small and grow to hyper-scale (>30PB) with ease. Grids can contain a heterogeneous mix of hardware from different vendors and may include QuantaStor virtual storage appliances. Grids can also span sites to form highly-available object storage clouds and can be used to setup easy DR replication policies in just a few clicks.
  • Strong focus on user experience which makes the QuantaStor web management interface easily understood and effective for IT generalists. OSNEXUS was founded by former Veritas Software engineers with a focus on eliminating the complexity found in traditional SAN/NAS appliances.
  • Uses leading open storage technologies (Ceph, ZFS, Gluster, XFS) so that a broad range of use cases can be solved an so that customer data lives on a stable platform that will be around for the long term. No other platform brings scale-out and scale-up together in a single platform on open tech. Most competitors are delivering storage on proprietary hardware, proprietary software, or some combination of the two which creates vendor lock-in and increased risk for customers.
