    Description

    The [Lenovo ThinkSystem SR530](#Lenovo ThinkSystem SR530) is a high-density 1U rack server designed for small-to-large enterprises requiring industry-leading reliability, management, and cost-optimized performanceLenovo Press. Featuring up to two 2nd-Generation Intel® Xeon® Scalable processors—each with up to 22 cores, 30.25 MB cache, and 10.4 GT/s UPI links—the SR530 accelerates multithreaded and virtualization workloads while maximizing processor utilization via Intel Turbo Boost 2.0, Hyper-Threading, Speed Select, AVX-512, and Deep Learning Boost (VNNI)Lenovo Press.

    Memory scales to 768 GB using 12× RDIMMs at up to 2933 MT/s, with advanced protection (ECC, SDDC/ADDDC, mirroring, rank sparing, scrubbing) to safeguard data integrity⎯all in a single-processor or dual-processor configurationLenovo Press. For storage, the SR530 offers up to eight 2.5″ AnyBay bays—supporting SAS, SATA, or direct-attach NVMe drives—or four 3.5″ hot-swap bays, plus two onboard U.2 NVMe ports and two M.2 SATA/NVMe boot slots (RAID 1) that free valuable drive bays for application dataLenovo Press

    I/O scalability is delivered via three low-profile PCIe 3.0 slots (x8/x16 configurations) and a LOM slot for embedded networking, enabling up to 6 GT/s per link and minimizing latency through Intel Integrated I/O technologyLenovo Documentation. Lenovo’s XClarity suite—embedded Controller, UEFI-based Provisioning Manager, Essentials toolkit, and centralized Administrator—streamlines everything from initial setup to firmware updates and proactive alerts (PFA/SMART), reducing provisioning time by up to 95 % while providing on-the-go monitoring via the XClarity Mobile appRouter Switch.

    Built-in enterprise reliability features such as Predictive Failure Analysis, light-path diagnostics, hot-swap power supplies/fans/drives, and ASHRAE A4 support (up to 45 °C) ensure 24×7 uptime in demanding environments. ThinkShield delivers comprehensive security from supply chain to decommissioning—featuring TPM 2.0, Secure Boot, Platform Firmware Resiliency, and optional chassis intrusion detection—to protect data throughout the server’s lifecycleLenovo Press.
