Xcellis Workflow Storage


Xcellis Workflow Storage is high-performance shared storage for collaborative workflows—powered by StorNext 5, the industry’s fastest streaming file system. Engineered to solve the world’s toughest data management challenges.

What is Xcellis Workflow Storage?

Xcellis workflow storage enables high-speed shared access to your critical data. Powered by StorNext 5 data management software, it includes an Xcellis Workflow Director for system management and client connectivity, and RAID storage for data. This combination of software, compute, and storage is engineered to solve the world’s biggest storage challenges—and enables you to focus on your workflows rather than the storage. So you can do what you do best.

High-Performance, Massively Scalable Primary Storage

Most organizations that work with large amounts of data are familiar with the causes of their pain—large files, even larger data sets, more collaborators, shorter deadlines, nearly constant upgrades—but far less obvious is a way to address the situation. The ideal solution would be a storage system flexible enough to be right-sized for any large data workflow. One that is scalable enough to keep up with growing demands without performance degradation. A system collaborative enough to provide access, regardless of performance requirements. And finally, efficient enough to do all this and stay on budget. Quantum Xcellis™ workflow storage is just that.

Converged Architecture

Xcellis optimizes workflow and shared access by combining functions that were formerly provided by separate components into a compact, space- and energy-saving solution. Xcellis manages high-speed disk for the most demanding workflows, multi-protocol SAN and LAN client access, single-pane-of-glass management and monitoring, and automatic data movement to low-cost storage such as cloud, object, and tape. Xcellis maximizes operational and workflow efficiency, and reduces the cost of data storage.

Continuous Scalability

Other scalable storage systems require additional system acceleration units or compute-heavy expansion nodes in order to scale. These units increase the cost and network complexity of scaling. Xcellis scales simply by adding storage arrays so every dollar invested pays off in more capacity and greater bandwidth. Plus, the initial investment in Xcellis is protected, eliminating forklift upgrades in order to scale.

Unified Access

Demanding workflows have spawned an increased need for collaboration and expanded teams. By combining both SAN performance and the ease of NAS connectivity, Xcellis extends collaboration to the broadest range of users. This provides the right level of performance to the right people, improves collaboration, and simplifies deployments and workflows.

Efficiency And Enablement

Xcellis reduces or eliminates the need to maintain multiple storage systems, the network traffic to move data between them, and the time and headcount to manage them. By using converged storage and access, organizations can scale their storage system more efficiently by leveraging every dollar spent to benefit all connected users.

Xcellis optimizes workflows, accelerates time to insight, and empowers organizations to do more with their data.

Features & Benefits:
