    Description

    The [Lenovo ThinkSystem SR850 V3](#Lenovo ThinkSystem SR850 V3) is a purpose-built 2U rack server that delivers affordable scalability on an industry-standard x86 platform, ideal for SAP HANA, virtualization, and database workloads Lenovo Press. Its intelligent “pay-as-you-grow” design lets you start with two 4th Gen Intel® Xeon® Scalable processors and 32 TruDDR5 DIMMs, then upgrade to four CPUs and 64 DIMMs for up to 16 TB of memory to meet evolving next-gen demands Lenovo Press.

    Supporting up to 24 direct-attach AnyBay 2.5″ drive bays (SAS, SATA, NVMe) and two mirrored 7 mm or M.2 rear boot drives, the SR850 V3 eliminates I/O bottlenecks for transactional processing, HPC, and big-data analytics—while maintaining tight compliance windows for backup and replication Lenovo Press.

    For GPU-accelerated workloads, install up to four double-width 350 W GPUs or eight single-width 75 W GPUs; optional Lenovo Neptune™ liquid-to-air hybrid cooling ensures optimal thermals and lower acoustic noise under full load Lenovo Press.

    Embedded management through [Lenovo XClarity Controller](#XClarity management) and centralized XClarity Administrator automates deployment, updates, and health monitoring—reducing manual provisioning by up to 95 % and freeing IT staff for strategic projectsLenovo Documentation.

    Usage Scenarios

    For in-memory databases like SAP HANA, the SR850 V3’s mesh-connected CPUs and 16 TB DDR5 deliver sub-millisecond query response and high VM density Lenovo Press. In AI training & inference, four double-width GPUs with NVLink and hybrid cooling scale elastically for deep-learning workloads without thermal throttling Lenovo Press. For virtualization & VDI, up to 480 threads and 24 NVMe drives ensure rapid boot storms and consistent desktop performance across hundreds of users Lenovo Press.

    Frequently Asked Questions

    Q1: How does “pay-as-you-grow” CPU expansion work?
    A1: Begin with two CPUs and 32 DIMMs, then add a customer-installable tray to expand to four CPUs and 64 DIMMs without downtime Lenovo Press.

    Q2: Can the SR850 V3 support NVMe boot drives?
    A2: Yes—two rear-mounted 7 mm or M.2 drives can be used for OS boot, freeing primary bays for data storage and accelerating boot times over USB/SD keys Lenovo Press.

    Q3: What cooling options are available for GPUs?
    A3: Lenovo Neptune™ liquid-to-air hybrid cooling removes heat via a closed-loop exchanger on GPU modules, reducing PSU load and acoustic noise by up to 30 % Lenovo Press.

    Q4: Which reliability features are standard?
    A4: Includes Predictive Failure Analysis for CPUs, DIMMs, fans, and PSUs; light-path LEDs for diagnostics; and Root of Trust firmware protection with TPM 2.0/TCM Lenovo Documentation.

    Q5: How many PCIe lanes are available per processor?
    A5: Each 4th Gen Xeon CPU provides 80 PCIe 5.0 lanes for networking and storage accelerators, a 67 % increase over previous generations Lenovo Press.
