    Description

    The [Lenovo ThinkSystem SR630 V3](#Lenovo ThinkSystem SR630 V3) is a 1U rack server optimized for dense, dual-socket compute, supporting up to two 5th-Generation Intel® Xeon® Scalable processors (Emerald Rapids) with up to 64 cores and 128 threads for parallel workloads Lenovo Press. It delivers up to 59 % higher performance over its predecessor, thanks to PCIe Gen5 lanes (80 per CPU) and DDR5-5600 memory speeds across 32 DIMM slots (16 per CPU) Lenovo Press.

    Storage options include up to four 3.5″ or twelve 2.5″ AnyBay bays, or sixteen EDSFF E1.S NVMe drives for sub-millisecond I/O, plus two rear 7 mm SATA/NVMe boot drives and two internal M.2 boot drives, all managed via VROC/VMD or software RAID (0, 1, 5, 10)Lenovo Press. With up to five PCIe 4.0/5.0 slots and one OCP 3.0 slot, the SR630 V3 scales for accelerators or high-speed networking, while Lenovo Neptune™ liquid cooling keeps GPUs and CPUs within optimal thermal envelopes Lenovo Documentation.

    Embedded Lenovo XClarity Controller simplifies foundation server management with agent-free deployment, firmware updates, and health monitoring, reducing provisioning time by up to 95 % when used with XClarity Administrator Lenovo Documentation.

    Flexible CPU, storage, and networking configurations let you right-size the server for cloud native microservices or traditional enterprise workloads, scaling seamlessly via XClarity automation Lenovo Documentation.

    Frequently Asked Questions

    Q1: What distinguishes the SR630 V3 from the SR630 V2?
    A1: The V3 adds support for 5th-Gen Xeon (up to 64 cores/CPU), PCIe 5.0 lanes (80 vs. 64), and DDR5 (up to 5600 MHz) vs. DDR4/PCIe 4.0 on the V2 Lenovo Press.

    Q2: Can I use U.2 NVMe drives and SATA HDDs in the same bay?
    A2: Yes—AnyBay bays support SAS, SATA, or U.2 NVMe drives interchangeably for maximum flexibility Lenovo Press.

    Q3: How does Neptune™ liquid cooling integrate with this 1U chassis?
    A3: Select GPU modules use a closed-loop heat exchanger that fits in the SR630 V3 chassis, offloading CPU/GPU heat to a liquid-cooled radiator without added plumbing.

    Q4: What RAID and boot options are available?
    A4: Supports software RAID (0, 1, 5, 10), VROC/VMD for NVMe boot, and optional PCIe RAID/HBA cards; two M.2 SATA/NVMe boot drives are integrated without consuming PCIe slots Lenovo Press.

    Q5: How do I manage and monitor multiple SR630 V3 servers?
    A5: Use Lenovo XClarity Controller embedded on each server plus XClarity Administrator for centralized 1:many provisioning, monitoring, firmware updates, and energy optimization Lenovo Documentation.
