OSNEXUS QuantaStor Virtual Storage Appliances (VSAs) increase the performance and efficiency of data centers as storage appliances are shifted to run as virtual machines thereby providing shared storage without the cost of additional dedicated hardware and software. The QuantaStor VSAs can also be combined into a heterogeneous grid of virtual and physical appliances that scales to 64 nodes. Integrating storage assets from multiple vendors across sites, on-premises, or across global datacenters makes QuantaStor a powerful tool for increasing IT efficiency and agility in one of the largest IT cost centers.

Heterogenous Grid Technology

QuantaStor's grid technology enables organizations to build heterogeneous SDS storage grids using server hardware from multiple vendors along with VSAs. This makes managing a group of appliances as easy as managing a single unit. 

Multi-site Administration

From the storage grid, administrators can provision storage clouds with quotas for users and teams so that they can self-service storage from the grid.  This is a powerful tool to keep IT costs down and enable organizations to do more with limited staffing. In addition, the QuantaStor's patent pending role-based-access-control (RBAC) system provides the necessary tools to limit the scope of operations users can execute as well as the visibility of what storage resources can be viewed within the grid.

Multi-tenancy for 3rd Party SANs

Using QuantaStor VSAs, organizations can boost the value of their investments in existing SAN deployments (Netapp, EMC, Dell, HP) by making the existing storage multi-tenant. By delivering storage via FC or iSCSI to a VSA the storage is now the basis for a new virtual appliance and can now be used to deliver file, block and object capabilities with features that go far beyond the limits of traditional SANs.

VSA Software Licensing Advantages

Traditional SAN appliances typically have extra license fees for features such as disaster recovery, high availability, remote-replication, snapshots, compression, and encryption. By using QuantaStor as a VSA, enterprises can extend the capabilities of their SANs with all these features and more without having to buy more proprietary hardware and software licenses.
