Take the complexity out of complex solutions

Complex Storage Made Simple

Deploying solutions for Technical Computing, High Performance Computing (HPC), Analytics and Cloud environments can place a significant burden on IT. With the Lenovo Distributed Storage Solution for IBM® Spectrum Scale™ (DSS-G) clients can focus their efforts on maximizing user time instead of consuming valuable resources to design, optimize, install and support the infrastructure required to meet user demands.

Lenovo DSS-G is fulfilled through Lenovo Scalable Infrastructure (LeSI), leveraging decades of experience simplifying complex deployments for customers. With integrated, delivered, and fully-supported solutions that match best-industry components with optimized solution design, DSS-G provides scalable solutions that address the high-performance storage needs in the data center.

Powerful Combination

Lenovo DSS-G combines the performance of Lenovo ThinkSystem servers and Lenovo disk enclosures with industry-leading Spectrum Scale software to deliver a high-performance, scalable building-block approach to modern storage needs. Lenovo DSS-G allows organizations to start small and build incrementally, scaling both capacity and bandwidth. Customers now have the ability to perform online expansion to add building blocks within a solution, supporting the flexibility to grow their HPC storage with their requirements.

Optimized Design

Lenovo DSS-G features industry-leading ThinkSystem servers with powerful second-generation Intel® Xeon® Processor Scalable family CPUs, Lenovo 12Gbps SAS storage enclosures and drives, software, and networking components that allow for a wide choice of technology within an integrated solution, available in a pre-integrated rack or deployed in an existing customer rack.

Each solution is tested and optimized for reliability, interoperability and maximum performance, so clients can quickly deploy the system and get to work achieving their business goals. With DSS-G high-storage density and I/O performance, you gain all the reliability, integration and interoperability of a high-capacity Spectrum Scale-based storage architecture.

Increase Results

Clients are expanding the use of Technical Computing and HPC to solve complex problems. These environments need high-capacity storage with low-latency data access as well as quick rebuild times in the event of disk failure to maintain data integrity and system availability.

As an integral part of the Lenovo Scalable Infrastructure (LeSI) portfolio, the declustered RAID capability of Lenovo DSS-G provides extreme performance, reliability, and data integrity, with rebuild times up to 8x faster than controller-based storage. DSS-G offers a modular building-block approach to Spectrum Scale with nearly linear performance and capacity scaling, while maintaining a global namespace that enables users to view everything as a single storage cluster. These features allow users to quickly put the system to work, and easily grow with new storage demands, and increase their overall productivity.

End-to-end Support

Lenovo DSS-G is built, tested, delivered, and supported as part of an overall LeSI deployment. You receive single point-of-contact, solution-level support that includes components to deliver maximum system availability throughout the life of the system. This enables you to spend less time deploying and maintaining systems and more time delivering results.
