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.

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

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 supports three editions of IBM Spectrum Scale:

  • IBM Spectrum Scale Data Access Edition (DAE) provides base GPFS functions including Information Lifecycle Management (ILM), Active File Management (AFM), and Clustered NFS (CNFS) in Linux environments.
  • IBM Spectrum Scale Data Management Edition (DME) provides all the features of the Data Access Edition plus advanced features like asynchronous multi-site disaster recovery, native encryption support, Transparent Cloud Tiering.
  • IBM Spectrum Scale Erasure Code Edition (ECE) provides all the features of the Data Management Edition plus support for storage rich servers with network-dispersed erasure coding, distributing data and metadata across the internal disks of a cluster of servers.

Optimized Design

DSS-G features industry-leading ThinkSystem servers with powerful 3rd 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.

DSS Product Overview

Distributed Storage Solution Configurations for IBM Spectrum Scale

The following figure shows two of the configurations available, the G204 (2x SR650 V2 and 4x D1224) and the G260 (2x SR650 V2 and 6x D3284). See the model section for all available configurations.

DSS-G Components

DSS-G with ThinkSystem V2 is more than doubling the performance over the previous generation and supports up to 25% more capacity in a single building block. It can be licensed by the number of drives installed or alternatively the usable capacity, rather than the number of processor cores or the number of connected clients, so there are no added licenses for other servers or clients that mount and work with the file system.
