Key featuresThe SR550 server offers a balance of processing power, storage capacity, and cost for small and mediumbusinesses up to the large enterprise. Ease of use and comprehensive systems management tools helpmake deployment easier and efficient design improves your business environment and helps saveoperational costs.Scalability and performanceThe SR550 server offers numerous features to boost performance, improve scalability, and reduce costs:Improves productivity by offering superior system performance with the Intel Xeon ProcessorScalable Family with up to 20-core processors, up to 27.5 MB of last level cache (LLC), up to2666 MHz memory speeds, and up to 10.4 GT/s Ultra Path Interconnect (UPI) links.Support for up to two processors, 40 cores, and 80 threads allows to maximize theconcurrent execution of multithreaded applications.Intelligent and adaptive system performance with energy efficient Intel Turbo Boost 2.0Technology allows CPU cores to run at maximum speeds during peak workloads bytemporarily going beyond processor thermal design power (TDP).Intel Hyper-Threading Technology boosts performance for multithreaded applications byenabling simultaneous multithreading within each processor core, up to two threads per core.Intel Virtualization Technology integrates hardware-level virtualization hooks that allowoperating system vendors to better utilize the hardware for virtualization workloads.Intel Advanced Vector Extensions 512 (AVX-512) enable acceleration of enterprise-class andhigh performance computing (HPC) workloads.Helps maximize system performance for data intensive applications with up to 2666 MHz memoryspeeds 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 forperformance-optimized configurations or up to 12x 3.5-inch drives for capacity-optimizedconfigurations, providing a wide selection of SAS/SATA HDDs/SSDs.Provides I/O scalability with the LOM slot and up to six PCI Express (PCIe) 3.0 I/O expansion slots ina 2U rack form factor.Reduces I/O latency and increases overall system performance with Intel Integrated I/O Technologythat embeds the PCI Express 3.0 controller into the Intel Xeon Processor Scalable Family.Availability and serviceabilityThe SR550 server provides many features to simplify serviceability and increase system uptime:Offers protection in the event of a non-correctable memory failure with Single Device DataCorrection (SDDC, also known as Chipkill, requires x4-based DIMMs), Adaptive Double Device DataCorrection (ADDDC, also known as Redundant Bit Steering [RBS], requires x4-based DIMMs andIntel Xeon Gold or Platinum processors), memory mirroring, and memory rank sparing.Provides easy access to upgrades and serviceable parts (such as processors, memory DIMMs, andadapter cards) with tool-less cover removal.Offers affordable data protection with software RAID and Simple Swap drives and advancedhardware RAID data redundancy with hot-swap drives.Provides availability for applications with redundant hot-swap power supplies and redundant non-hot-swap fans.Allows preventive actions in advance of possible failure, thereby increasing server uptime andapplication availability with Proactive Platform Alerts (including PFA and SMART alerts) forprocessors, voltage regulators, memory, internal storage (SAS/SATA HDDs and SSDs, M.2 storage),fans, power supplies, RAID controllers, and server ambient and sub-component temperatures.Lenovo ThinkSystem SR550 Server 2
