    H3C UniServer R5300 G6 12LFF direct-connect barebone platform

    H3C UniServer R5300 G6 12LFF direct-connect barebone platform. Price excludes CPUs, memory, drives, GPUs, NICs, RAID controllers, and power supplies; all of these components must be selected and priced separately. CPU unit price × 2; power supply module unit price × 4. The chassis image is an R5300 G6 exterior reference only; internal topology and 12LFF layout are subject to the actual BOM. The exact supply scope and part numbers for fans, heatsinks, backplanes, carriers, cables, and rails must be verified in the order. This price does not apply to the 24LFF model.

    • 12LFF bare platform; CPU, memory, drives, GPUs, NICs, RAID card and power supplies are separate selections
    • Direct-connect topology; validate GPUs and slots against the approved BOM
    • 32 DDR5 slots; capacity and speed depend on the selected CPU, DIMMs and population
    • 4U air-cooled platform reference; exact part numbers, backplane and inclusions require confirmation

    Published model specifications describe available options, not the delivered configuration.

    Specifications & selection notes

    Scope and configuration boundaries

    Specification scopeR5300 G6 platform reference for this 12LFF configuration intent. Exact part numbers, backplane, included components and compatibility require an approved BOM.
    Scope of this listingBare-platform listing excludes CPU, memory, drives, GPUs, NICs, RAID card and power supplies. Other inclusions require confirmation.

    Processors

    Platform processor supportUp to 2 4th/5th Gen Intel Xeon Scalable processors; validate the selected CPU and cooling configuration against the compatibility list.
    Platform core-count limitUp to 64 cores per processor; this is not the installed core count.
    Processor power qualificationThe current product page lists up to 385W, while User Guide 6W106 lists 350W. Resolve this revision difference using the approved CPU, heatsink and server configuration.

    Memory

    Memory slots32 DDR5 DIMM slots: 8 channels per CPU, 2 slots per channel; the corresponding CPU must be installed.
    Memory capacity conditionsThe family maximum is 12TB with two CPUs. Guide 6W106 lists up to 6TB per 4th Gen CPU and 4TB per 5th Gen CPU. A 12TB configuration requires qualification of the exact CPU, DIMMs and server.
    Operating memory speedThe platform maximum of 5600MT/s requires a suitable CPU and 1DPC. Guide 6W106 lists 4800 for 4th Gen 1DPC, 5600 for 5th Gen 1DPC, and 4400MT/s for 2DPC. Individual CPU limits may be lower.
    CXL and HBM optionsThe official family page lists CXL 1.1 and HBM as restricted options. Confirm availability, CPU/component compatibility and capacity separately; do not count them as installed DDR5 or GPU VRAM.

    Storage and RAID

    Drive-cage configurationThis listing is a 12LFF configuration intent, not a 24-bay model. Validate the backplane, carriers and part numbers in the BOM.
    NVMe baysUp to 8 NVMe bays, subject to the UniBay backplane, cabling, controller and configuration; this does not mean 8 drives are installed.
    Onboard M.2The platform supports 2 onboard M.2 devices; confirm actual drives, boot configuration and compatibility in the BOM.
    RAID capabilitiesRAID levels and Tri-Mode depend on the selected controller, licence and drives. The family lists 0/1/10/5/6/50/60; not every controller supports every level.

    GPU and PCIe expansion

    GPU topologyDirect-connect topology configuration intent; validate the GPU node board, uplinks and exact part numbers in the approved BOM.
    GPU qualification boundaryAn applicable 8-slot module supports a configuration of 8 full-height, full-length, double-width GPUs. Exact models, count, power, slot use and qualification require an approved BOM; 8 installed GPUs are not implied.
    PCIe slot reference8-slot direct node board: 10 standard PCIe 5.0 x16 slots. OCP and dedicated RAID interfaces are separate; confirm sharing and usable slots in the BOM.
    NVLink interconnectRequires compatible GPUs and an optional NVLink Bridge. The guide describes bridging two adjacent GPUs; this is not an 8-GPU NVLink fabric or support for every GPU model.

    Networking

    Network expansionThe official family specification lists 1/10/25/50/100/200/400GE PCIe NICs. Confirm NIC and port speeds against the supported-parts list; 800G OSFP is not promised.
    OCP slot1 OCP 3.0 interface. Multi-host is conditional; validate the specific NIC, cables and server configuration.
    Management port1 dedicated 1GbE management port.

    Power and cooling

    Power-supply options4-module power architecture. Family options include 2000/2400/2700W Platinum and 3200W Titanium modules; confirm availability, input voltage and part numbers.
    Power redundancyThe family specification lists N+N hot-swap power redundancy. Usable redundant power depends on installed modules and load; do not substitute a universal 1+1 claim or fan N+1 redundancy.
    Standard cooling8 hot-swap 8056 fans with N+1 redundancy (4 dual-fan modules); this is not evidence of a liquid-cooled configuration.

    Chassis and environment

    Form factor4U rack-mount.
    Chassis dimensions174.8×447×828mm (H×W×D, without the security bezel); depth with the bezel is 856mm.
    Operating temperatureFamily standard operating range: 5–35°C, subject to CPU, GPU, drive and configuration restrictions.

    Selection guides & questions

    Are the published specifications included in the quotation?

    No. This page describes a 12LFF configuration intent. Bare platforms and processor bundles have different inclusions. Confirm each CPU, memory, GPU, drive, NIC, RAID card and power supply against the selected SKU and written quotation.

    Does the R5300 G6 include liquid cooling and an 800G NIC by default?

    No. The verified documentation describes an air-cooled platform and lists NIC options up to 400GE. Liquid cooling and 800G must not be presented as default inclusions. Confirm the exact NIC part number, support list and delivered configuration.

    Are all eight GPUs interconnected through NVLink?

    Not necessarily. NVLink Bridges are optional for specific compatible GPUs and adjacent installation positions; they do not imply eight-way all-to-all NVLink. Validate the direct-connect or PCIe-switch module, exact GPU part numbers and interconnect requirements together.

    How should memory capacity, speed and warranty be confirmed?

    32 DIMM slots do not mean that every CPU supports the family maximum capacity or speed. Check CPU limits, DIMM part numbers and population rules. Warranty term and response hours depend on the purchased service package and contract.
