Lenovo ThinkSystem SR550 Server (Xeon SP Gen 1 /
Gen 2)
Product Guide (withdrawn product)
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 second generation of 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 2933 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 a LOM slot
and up to 6x PCIe slots. The built-in next-generation Lenovo XClarity Controller provides advanced service
processor control, monitoring, and alerting functions.
The following figure shows the ThinkSystem SR550 server with 3.5-inch front hot-swap drives. Other drive
configurations are also available.

Did you know?
The SR550 server delivers impressive compute power per watt, featuring 80 PLUS Titanium and Platinum
redundant power supplies that can deliver 96% (Titanium) or 94% (Platinum) efficiency at 50% load when
connected to a 200 - 240 V AC power source.
The SR550 server is designed to meet ASHRAE A4 standards (up to 45 °C [113 °F]) in select
configurations, which enable customers to lower energy costs, while still maintaining world-class reliability.

Key features
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.
Scalability and performance
The SR550 server offers numerous features to boost performance, improve scalability, and reduce costs:
Improves productivity by offering superior system performance with the second generation of the Intel
Xeon Processor Scalable Family with up to 22-core processors, up to 30.25 MB of last level cache
(LLC), up to 2933 MHz memory speeds, and up to 10.4 GT/s Ultra Path Interconnect (UPI) links.
Support for up to two processors, 44 cores, and 88 threads allows to maximize the concurrent
execution of multithreaded applications.
Intelligent and adaptive system performance with energy efficient Intel Turbo Boost 2.0
Technology allows CPU cores to run at maximum speeds during peak workloads by
temporarily going beyond processor thermal design power (TDP).
Intel Hyper-Threading Technology boosts performance for multithreaded applications by
enabling simultaneous multithreading within each processor core, up to two threads per core.
Intel Virtualization Technology integrates hardware-level virtualization hooks that allow
operating system vendors to better utilize the hardware for virtualization workloads.
Intel Speed Select Technology provides improvements in server utilization and guaranteed
per-core performance service levels with more granular control over processor performance.
Intel Deep Learning Boost (Vector Neural Network Instruction set [VNNI]) is designed to
deliver significant, more efficient Deep Learning (Inference) acceleration for high-performance
Artificial Intelligence (AI) workloads.
Intel Advanced Vector Extensions 512 (AVX-512) enable acceleration of enterprise-class and
high performance computing (HPC) workloads.
Helps maximize system performance for data intensive applications with up to 2933 MHz memory
speeds and up to 768 GB of memory capacity.
Offers flexible and scalable internal storage in a 2U rack form factor with up to 16x 2.5-inch drives for
performance-optimized configurations or up to 12x 3.5-inch drives for capacity-optimized
configurations, providing a wide selection of SAS/SATA HDDs/SSDs.
Provides I/O scalability with a LOM slot and up to six PCI Express (PCIe) 3.0 I/O expansion slots in a
2U rack form factor.
Reduces I/O latency and increases overall system performance with Intel Integrated I/O Technology
that embeds the PCI Express 3.0 controller into the Intel Xeon Processor Scalable Family.
Availability and serviceability
The SR550 server provides many features to simplify serviceability and increase system uptime:
Designed to run 24 hours a day, 7 days a week
Offers protection in the event of a non-correctable memory failure with Single Device Data Correction
(SDDC, also known as Chipkill, requires x4-based DIMMs), Adaptive Double Device Data Correction
(ADDDC, also known as Redundant Bit Steering [RBS], requires x4-based DIMMs and Intel
Xeon Gold or Platinum processors), memory mirroring, and memory rank sparing.
Provides easy access to upgrades and serviceable parts (such as processors, memory DIMMs, and
adapter cards) with tool-less cover removal.
Offers affordable data protection with software RAID and Simple Swap drives and advanced
hardware RAID data redundancy with hot-swap drives.
