ThinkSystem ST550, Xeon Silver 4110, 4x 32GB RDIMM DDR4-2666, 3x 900GB HDD 10K 2.5" SAS12Gbps, 16x 2.5", 8x 2.5" SATA/SAS HS, Security Bezel/Chassis Intrusion Switch/TPM 1.2, XClarity Standard, 2x 750W Platinum

Enterprise enabled, ROBO ready

The Lenovo ThinkSystem ST550 is a scalable 4U tower server that features powerful Intel® Xeon® processor Scalable family CPUs. It provides the performance and reliability you expect from the data center, but optimized for office environments, with physical security and whisper-quiet operation. Its compact footprint uses 37 percent less space than its predecessor, making it ideal for under-desk, deskside, or rack-mount use. ST550 is ideal for email/file/print and web serving, IT infrastructure, virtualization, VDI, and private cloud.

Compact, secure, flexible

ST550 supports up to 96.4TB of internal storage capacity, and Lenovo AnyBay technology enables the mixing and matching of storage types (U.2/SAS/SATA) in the same bays. Up to 6x PCIe adapter slots and multiple hardware and software RAID options offer the flexibility you need for NICs, GPUs, and other adapters.

Physical and software security technologies, including lockable security bezel, Kensington lock slot, chassis intrusion switch, and TPM 1.2/2.0, are ideal for remote locations without the protection of a data center. ST550 also offers money-saving features, such as highly energy-efficient 80 PLUS Platinum and Titanium hot-swap PSUs, continuous operation up to 45°C, and easy centralized management via XClarity software.

High-performance, reliable, manageable

ST550 features more processor cores, memory, and I/O bandwidth than previous generations. It also provides more memory channels; 12Gb SAS interconnects; and support for HDD, SSD, NVMe, and M.2 drives; as well as high-performance GPUs—all at a lower price than previous generations.

Faster processors and memory, more cores, and support for NVMe and M.2 drives contribute to significantly better performance than the previous generation*. In addition, optional NVMe drives provide ultra-fast storage that can be tiered for greater application performance. Combining enterprise-class RAS features and shared components across the server portfolio increases reliability, promotes greater peace of mind, and reduces TCO.

*Compared to Lenovo ThinkServer TD350.

XClarity Controller is the management hardware engine inside every ThinkSystem server, and XClarity Administrator centralizes management of your ThinkSystem and ThinkAgile infrastructure. With Redfish APIs and XClarity integrators you can easily integrate the Lenovo infrastructure into higher-level IT applications.
