Qumulo Stratus: Cryptographically Isolated, Edge-to-Core‑to‑Cloud, Multi‑Tenant Data Platform

Architectural evolution, inspired by hyper-scale deployments, delivers sovereign‑grade security, combining strict tenant isolation with a shared-nothing data core and unified file‑and‑object services for the world’s most mission-critical workloads.

Qumulo, Inc., the leader in enterprise-wide unstructured data management, today introduced Qumulo Stratus, a breakthrough multi‑tenancy architecture that sets a new standard for data isolation, performance, and manageability across on‑premises and public‑cloud environments. Stratus is the first storage architecture to combine “shared‑nothing” tenant segregation with cryptographically assured boundaries, enabling every tenant to operate as if it has its own private infrastructure while still benefiting from the global efficiency of Qumulo’s scale‑out DataCore and Cloud Data Fabric.

Qumulo Stratus Cryptographically Assured Multi-tenant Architecture.

Stratus was engineered in collaboration with agencies and enterprises that cannot tolerate data co-mingling, such as national intelligence agencies safeguarding classified imagery and signals, global banks isolating regulated workloads, university consortia sharing petabyte physics labs, and life‑sciences leaders inventing and protecting genomic IP. By insulating tenants cryptographically and operationally, Stratus satisfies regulatory mandates from government entities such as the National Institute of Standards and Technology (NIST) , while slashing infrastructure creep and administrative overhead.

“Enterprises and public‑sector agencies no longer have to choose between security and scale,” said Qumulo President and CEO Douglas Gourlay. “Stratus erases that trade‑off. We’ve fused uncompromising cryptographic isolation with the elasticity of cloud and the performance of bare‑metal and accelerated computing, delivering a platform worthy of the world’s most sensitive data.”

Breakthrough Architecture

Stratus enables organizations to maintain strict data and infrastructure isolation while reaping the economic benefits and scalability of a shared-nothing data core, delivering the following benefits:

• Cryptographically Sealed Tenancy – Delivers true Zero Trust and Least Privilege for data management. Each tenant can use their own independent key management system and cryptographic keys, ensuring data at rest and in transit is invisible, even to cluster administrators.
• Disaggregated I/O & Data Planes – Compute, cache, and protocol services are provisioned per tenant as containers, VMs, bare metal, or accelerated computing platforms, preventing “noisy‑neighbor” contention while letting organizations scale performance independently from capacity.
• Unified File & Object Access – Stratus presents NFS, SMB, and S3 interfaces concurrently, enabling modern analytics pipelines and legacy applications to share the same data without copies or gateways.
• Cloud‑Native & On‑Premises Harmony – A single global namespace spans data centers and every major hyperscaler, backed by Qumulo’s real‑time analytics and policy‑driven data placement. With support for AWS, Azure, Google Cloud, and Oracle Cloud, Qumulo delivers organizations unparalleled choice and flexibility in using the cloud services that best meet their business objectives.
• Tenant‑Specific Enterprise Services – Per‑tenant Active Directory, Domain Name Services, Hardware Security Modules, and SIEM/audit domains - simplify Zero Trust compliance for government, defense, financial services, healthcare, and service‑provider environments.

"With Qumulo Stratus’s innovative cryptographic isolation technology, sensitive data remains protected while offering the flexibility and efficiency necessary for mission-critical operations," said Qumulo Chief Technology Officer Kiran Bhageshapur. "This enables both federal and enterprise customers to concentrate on their core missions with the confidence that they can meet their regulatory compliance and security objectives without compromising performance or scalability.”

Availability

Stratus is entering limited availability and private preview and will be generally available in Qumulo Core 8 for certified on‑premises platforms, AWS, Microsoft Azure, Google Cloud, and Oracle Cloud in the second half of 2025.
