    H3C · R5300 G6 12LFF PCIe-switch / 2×6526Y

    H3C UniServer R5300 G6 12LFF PCIe-switch platform · Dual 6526Y

    Proposed R5300 G6 12LFF PCIe-switch platform configuration for quotation, including 2 Intel Xeon Gold 6526Y processors in the quoted scope. The exact platform part number and inclusion of power supplies, fans, heatsinks, backplanes, cables, and rails remain to be confirmed. Memory, drives, GPUs, and NICs are priced as separate configuration requests; confirm each included item in the formal BOM to avoid double billing. This record does not establish system certification, stock availability, or a complete configuration ready to order. The R5300 G6 chassis image is an exterior reference; internal direct-connect/PCIe-switch structure and 12LFF bays are subject to the configuration list.

    • 12LFF configuration intent; CPU quotation scope: 2 × Intel Xeon Gold 6526Y
    • PCIe-switch topology; validate GPUs and slots against the approved BOM
    • 32 DDR5 slots; 6526Y up to 5200MT/s at 1DPC; validate capacity and operating speed in the BOM
    • 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 listingConfiguration intent includes the quotation scope of 2 Intel Xeon Gold 6526Y processors. This is not evidence of installed components or certified system compatibility; confirm all other inclusions in the approved BOM.

    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.
    Listed CPU referenceIntel Xeon Gold 6526Y: 16 cores/32 threads, 195W TDP at the default performance profile; this configuration intent specifies 2 processors.

    Memory

    Memory slots32 DDR5 DIMM slots: 8 channels per CPU, 2 slots per channel; the corresponding CPU must be installed.
    Memory capacity conditionsThe listed 6526Y supports up to 4TB per CPU, giving an 8TB two-CPU ceiling before DIMM and system BOM qualification. This is not installed memory or an 8TB configuration guarantee.
    Operating memory speedThe listed 6526Y supports up to 5200MT/s at 1DPC. Guide 6W106 lists up to 4400MT/s at 2DPC. The lowest CPU, DIMM and platform limit applies, not the DIMM label speed.
    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 topologyPCIe-switch 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 switch module: 8 double-width GPU slots plus 4 single-width standard PCIe 5.0 x16 slots. OCP and dedicated RAID interfaces are separate; confirm sharing and uplinks 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.
