xFusion FusionServer 2158H V8
AMD EPYC 9005 up to 192 cores · 12 DDR5 DIMM slots
Up to 4 dual-width GPUs · 10 PCIe 5.0 slots · 2 × OCP 3.0
A next-generation 2U single-socket rack server built on the AMD EPYC 9004/9005 platform. With up to 192 cores in one processor, twelve DDR5 DIMM slots, ten PCIe 5.0 slots, two hot-swap OCP 3.0 NICs and room for up to four dual-width accelerators, the 2158H V8 gives you the performance of a dual-socket node with the simpler economics of a single CPU — ideal for virtualization, databases, big-data analytics, private cloud and GPU-accelerated inference.
Virtualization & cloud
Up to 192 cores in one socket consolidate very large VM and container flees efficiently.
Big data & databases
High core counts, large memory capacity and fast NVMe storage power analytics workloads.
AI inference & GPU
Up to four dual-width GPUs plus a DPU, all on PCIe 5.0 bandwidth.
Single-socket value
Dual-socket-class performance with one CPU means lower licensing and simpler service.

How we prepare every server
Configuration check
We verify CPU, memory, drives and cards against your order and the official spec.
BIOS & firmware
Firmware is updated and BIOS settings (boot order, virtualization, SR-IOV) are applied.
Stress test
CPU, memory and accelerators are exercised to confirm stability under load.
Storage & RAID
RAID arrays are built and every drive is confirmed healthy with no errors.
Test & record
The unit is tested, labels verified, and photographed for your records.
Export packing
Secure packaging protects the server during international air or sea freight.
Why xFusion
