Built-in to the platform and unifies management of QuantaStor storage servers and clusters across racks, sites, and clouds.

End-to-End Security

Advanced RBAC, end-to-end encryption support, and compliance with NIST 800-53, 800-171, HIPAA & CJIS.

Unified File, Block & Object

All major storage protocols are supported including NFS/SMB, iSCSI/FC, and S3.


Broadest hardware portfolio and deep hardware integration

Built-on an Open Storage Foundation

ZFS Integrated with enterprise-grade open storage technologies (Ceph & ZFS).

QuantaStor’s intuitive web interface is accessible from every server within a given Storage Grid with no additional software to install.

Scale-Up Clusters

  • Provides iSCSI/FC & SMB/NFS in compact low-cost footprint
  • Uses NVMe and/or SAS shared storage connected to 2 or 3 clustered servers for high availability
  • Scale up to 6x JBODs (~600 disks) per cluster (> 10PB)
  • Grid technology spans clusters for unified management, replication, global namespaces, and scalability to over 100PB per storage grid.
  • Supports dual-ported NVMe for high-performance use cases like HPC and databases

Scale-Out Clusters

  • Provides unified file, block and S3 object storage in a unified cluster architecture
  • Supports all major protocols S3, NFS, SMB, iSCSI, and FC
  • Deploy multiple clusters per Storage Grid
  • Scalable to over 100PB per Storage Grid
  • Native file and block protocol access provides high performance for HPC use cases (CephFS, Ceph RBD)
  • Supports erasure-coding and replica based fault-tolerance with high-availability domains at a host, rack, or site level
  • Makes it easy for IT staff to configure and operate without any Linux or Ceph knowledge
