Designed for a balance of processing power, storage capacity, and cost
Essential and Priced Within Reach
The Lenovo ThinkSystem SR550 dual-socket 2U rack server is ideal for small to large organizations that need performance, storage capacity, flexible I/O, and resiliency. With industry-leading reliability† and customer satisfaction‡, and designed to handle a wide range of workloads, SR550 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.
Flexible to Grow with Your Business
SR550 offers numerous features to increase performance and flexibility. It features two Intel® Xeon® Scalable family CPUs, with 43 percent more cores, faster memory, increased I/O, and more storage capacity than the previous generation*. SR550 is available with up to 120TB of storage, a 50 percent increase. Software and hardware RAID with simple-swap hard drives make it easy to manage storage needs.
SR550 also supports two internal M.2 boot drives, freeing up the other drive bays for additional storage capacity. Front USB 3.0 ports and optional front VGA simplify deployment and servicing. Plus, up to six PCIe adapter slots and several choices of optional 1GbE/10GbE LOM and NICs, 80 PLUS Platinum and Titanium PSUs, and continuous operation at 45°C, provide additional flexibility and cost savings.
Lenovo XClarity Controller is an all-new hardware embedded management engine common in every ThinkSystem server. XClarity Controller features an uncluttered graphical user interface, industry standard Redfish-compliant REST APIs, and enables booting in half the time of prior generation servers, with up to 6x faster firmware updates.
Lenovo XClarity Administrator is a virtualized application that centrally manages ThinkSystem servers, storage, and networking. Via reusable patterns and policies, it ramps up and scales infrastructure provisioning and maintenance. It serves as a central integration point to extend your data center management processes to physical IT. Running XClarity Integrators in external IT applications, or integrating through REST APIs, helps you further speed services provisioning, streamline IT management, and contain costs.
Lenovo is the leading provider of x86 systems for the data center. The portfolio includes rack, tower, blade, dense and converged systems, and supports enterprise class performance, reliability and security. Lenovo also offers a full range of networking, storage, software and solutions, and comprehensive services supporting business needs throughout the IT lifecycle.
