Lenovo ThinkSystem SR950 Planning and Implementation Guide

Lenovo® ThinkSystem™ SR950 is a high-performance server that is designed for your most demanding, mission-critical workloads. Suitable workloads include in-memory databases, large transactional databases, batch and real-time analytics, ERP, CRM, and virtualized server applications.

The powerful 4U ThinkSystem SR950 can grow from two to eight Intel Xeon Scalable Family processors, and with 96 DIMM sockets, supporting up to 12 TB of high-speed memory. The modular design of the SR950 aids upgrades and servicing with easy front or rear access to all major subsystems to maximize server availability.

The SR950 packs numerous fault-tolerant and high-availability features into a high-density, 4U rack-optimized design that reduces the space needed to support massive network computing operations and simplify servicing.

This book provides a general understanding of SR950 technology, components and management features. It also describes preparing and implementing the server, including power and cooling considerations, operating system installations, systems management, and firmware update tools.

This book is aimed at customers, Lenovo Business Partners, and Lenovo employees who want to understand the features and capabilities of the ThinkSystem SR950 and want to learn how to install and configure the server for use in production.
