Silver 3U rack chassis with ten front-facing blade nodes visible

GIGABYTE

GIGABYTE B343-C40-AAJ2 3U 10-node barebone server

SKU CH-E3XQ-VPNS5 MPN B343-C40-AAJ2

Holds ten independent AMD EPYC or Ryzen nodes in a 3U chassis with front-access Gen5 NVMe or SATA storage and dual 10GbE per node

  • 10 compute nodes in a single 3U chassis
  • Dual-channel DDR5 ECC memory support per node
  • 20 front-access 2.5″ NVMe/SATA drive bays total
  • Two 10GbE LAN ports per node via BCM57416
  • FHHL PCIe Gen5 x16 expansion slot per node

3U 10-Node Barebone Server

The GIGABYTE B343-C40-AAJ2 fits ten independent compute nodes into a single 3U rack chassis with front access. Each node accepts a single AMD EPYC 4005 or Ryzen 9000 series processor for high-density workloads. It targets operators who need maximum node count per rack unit without shared resources between nodes.

Dual-Channel DDR5 Memory per Node

Every node provides four UDIMM slots supporting dual-channel DDR5 ECC or non-ECC memory. This memory architecture is the primary factor determining per-node bandwidth and capacity limits for virtualisation or HPC tasks. Builders requiring registered DIMMs or more than four slots per node must choose a different platform.

Sustained Multi-Node Operation

Front-access drive bays and networking ports allow hot-swap maintenance while adjacent nodes continue running. Each node includes two 10Gb/s LAN ports via Broadcom BCM57416 and dual 2.5-inch Gen5 NVMe/SATA bays for local storage throughput. The shared 3U airflow design handles continuous load across all ten nodes without individual node throttling.
