Virtual Private Storage as a Service (VPSaaS)

Zadara Storage On-Premise as a Service (OPaaS) reduces the costs and complexity associated with data center storage by delivering fully managed SAN and NAS with consumption pricing. OPaaS replaces traditional storage purchases and leases and helps enterprises to become more efficient and agile while simplifying data portability.

For Service Providers, OPaaS delivers a cost model that reflects your business and growth. With zero Capex and pay-per-use pricing, we only charge you for additional storage capacity when you bring to a new customer.

Simplified Data Mobility
When you are ready, you can complement your in-houseVPSA OPaaS with VPSAOPaaS in remote data centers and public cloud service providers to simplify advanced IT processes such as business continuity, disaster recovery, high availability, scalability, quality of service, and more.

Of course, you can quickly and easily begin transforming your private cloud OPaaS environment into a hybrid cloud environment in the future with one of our industry-leading public cloud service providers. You have the flexibility to scale your Cloud storage as desired with VPSA.

Powered by Virtual Private Storage Arrays
OPaaS is powered by Zadara’s exclusive Virtual Private Storage Array™ (VPSA™) service, which had only been available in public and multi-tenant performance isolation. As an enterprise solution, Zadara VPSA OPaaS includes comprehensive support for SAN (iSCSI block) and NAS (CIFS/NFS file) protocols alongside hybrid SSD and HDD tiering so databases and applications gain access using native storage protocols, resulting in optimum reliability, availability, serviceability, and performance.

VPSA as On-Premise as a Service

  • Delivers better availability and simplified management at lower prices and no upfront costs

  • Brings an end to disruptive technology refresh cycles.

  • Improves business agility

  • Enables simplified data portability with comprehensive backup and disaster recovery to a global ecosystem of cloud service providers

  • Simplifies control with detailed metering and reports you can use

The Zadara Advantage

  • On-Premise as a Service (OPaaS) Unified SAN and NAS Storage
    Reduce the costs of enterprise SAN and NAS versus traditional purchased or leased storage.

  • Pay-as-you-go Pricing
    Immediately respond to changing requirements with pricing that matches actual VPSA™ usage.

  • Unified SAN and NAS Storage
    VPSA supports enterprise-grade needs using iSCSI, CIFS, and NFS protocols for accessing data.

  • Cloud-scale Performance
    Adapt VPSA performance higher or lower to match changes in workloads, number of servers, and desktop users.

  • Cloud-scale Capacity
    Scale VPSA capacity larger or smaller to accommodate any database or application needs.

Virtual Private Storage Array (VPSA™) Technology

Virtual Private Storage Arrays (VPSAs) include unique and patent-pending technologies by Zadara Storage to create SAN and NAS in the Cloud solutions. Only VPSA technology enables Cloud-based storage to deliver the same features and benefits of the traditional enterprise storage now powering enterprise data centers. As a result, enterprise organizations, small and medium businesses, and startups can move business databases and applications to the Cloud to achieve unsurpassed scalability, reliability, availability, serviceability, and performance


  • Enterprise-grade SAN and NAS in the Cloud
    While enterprise networking and computing effectively transitioned to the Cloud, enterprise storage could not, so compromised API- or object-based alternatives filled the void. Now, with VPSA by Zadara Storage, any organization gains access to an enterprise-grade SAN and NAS in the Cloud solution that complements current Cloud networking, computing, and storage.

  • Supports Business Databases and Applications
    Modern information technology (IT) architectures and infrastructures rely on essential SAN and NAS functionality. Yet, these are not supported by common Cloud-based storage alternatives so many databases and applications remain trapped within enterprise data centers. VPSAs use native block and file systems to serve storage to your applications using standard, familiar protocols with low latency and high performance. Only VPSA delivers SAN and NAS in the Cloud solutions that work with every business database and application.

  • Limitless Performance and Capacity Scalability
    As a Cloud-based solution, VPSA offers an essentially unlimited range of performance and capacity to support any database and application. SAN and NAS in the Cloud solutions rapidly adapt to changing requirements without disruptions, so organizations always experience the ideal level of usable performance and capacity and forever eliminate the need to over-or under-provision storage. Customers can pick the actual spindles and/or SSDs that they wish to use, in any mix. From that point, they are dedicated and never shared with others. You may at any time add more drives or give drives back, and monthly payment adjusts accordingly.

  • Unprecedented Control and Configuration
    Only VPSA delivers SAN and NAS in the Cloud solutions that give complete control of hardware configurations and storage settings. Users choose from a broad menu of hardware options to configure a custom VPSA, or select pre-configured solutions designed by Zadara Storage experts they can customize if desired. User are offered complete control for each application by choice of RAID levels, snapshot policies, remote mirroring frequencies, storage access protocols, drive mix and more. Flexible configurations allow users to accurately and precisely match the storage needs of their organizations, with or without the assistance of others.

  • Subscription-based Pricing by the Hour
    Users pay for SAN and NAS in the Cloud solutions using predictable, subscription-based pricing. Rates adjust to match the options selected by users, and usage is metered by the hour and billed periodically. This transforms storage costs into operational expenses (OpEx) and eliminates capital expenses (CapEx) to simplify planning, streamline budgeting, and improve return on investment (ROI).
