Lenovo Distributed Storage Solution for IBM Spectrum Scale (DSS-G)Product Guide

Lenovo Distributed Storage Solution for IBM Spectrum Scale (DSS-G) is a software-defined storage (SDS) solution for dense scalable file and object storage suitable for high-performance and data-intensive environments. Enterprises or organizations running HPC, Big Data or cloud workloads will benefit the most from the DSS-G implementation.

DSS-G combines the performance of the Lenovo ThinkSystem SR650 servers, Lenovo D1224 and D3284 storage enclosures, and industry leading IBM Spectrum Scale software to offer a high performance, scalable building block approach to modern storage needs.

Lenovo DSS-G is delivered as a pre-integrated, easy-to-deploy rack-level engineered solution that dramatically reduces time-to-value and total cost of ownership (TCO). All DSS-G base offerings described in this product guide are built on Lenovo ThinkSystem SR650 servers, Lenovo Storage D1224 Drive Enclosures with high-performance 2.5-inch SAS solid-state drives, and Lenovo Storage D3284 High-Density Drive Enclosures with large capacity 3.5-inch NL SAS HDDs.

Combined with IBM Spectrum Scale (formerly IBM General Parallel File System, GPFS), an industry leader in high-performance clustered file system, you have an ideal solution for the ultimate file and object storage solution for HPC and Big Data.

Lenovo DSS-G is licensed by the number of drives installed, 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.

Lenovo DSS-G supports online JBOD expansion. This enables a customer to grow the number of JBODs in an existing DSS-G building block without bringing down the file system, maximizing flexibility to scale storage capacity based on need.

With available Lenovo Premier Support Services, Lenovo provides a single point of entry for supporting the entire DSS-G solution, including the IBM Spectrum Scale software, for quicker problem determination and minimized downtime.

Lenovo DSS-G is fulfilled through Lenovo Scalable Infrastructure (LeSI), which offers a flexible framework for the development, configuration, build, delivery and support of engineered and integrated data center solutions. Lenovo thoroughly tests and optimizes all LeSI components for reliability, interoperability and maximum performance, so clients can quickly deploy the system and get to work achieving their business goals.
