Introduction

The Lenovo ThinkSystem SR550 dual-socket 2U rack server is ideal for small to large organizations that need industry-leading reliability, management, and security, as well as cost-optimized performance, storage capacity, and flexible I/O. Designed to handle a wide range of workloads, the SR550 server cost-effectively performs complex analytics on structured and unstructured data, speeds transactional systems, and powers through collaboration workloads with ever-growing data sets and large files shared within an organization.

Featuring the Intel Xeon Processor Scalable Family, the SR550 server offers a balance of performance, capacity and value. The SR550 server supports up to two processors, up to 768 GB of 2666 MHz TruDDR4 memory, up to 16x 2.5-inch or up to 12x 3.5-inch drive bays with an extensive choice of SAS/SATA SSDs and SAS/SATA HDDs, and flexible and scalable I/O expansion options with the LOM slot and up to 6x PCIe slots.

The SR550 server offers basic software RAID or advanced hardware RAID protection and a wide range of networking options, including embedded LOM, selectable LOM, ML2, and PCIe network adapters. The next-generation Lenovo XClarity Controller, which is built into the SR550 server, provides advanced service processor control, monitoring, and alerting functions.

The SR550 server offers a balance of processing power, storage capacity, and cost for small and medium businesses up to the large enterprise. Ease of use and comprehensive systems management tools help make deployment easier and efficient design improves your business environment and helps save operational costs.
