xFusion FusionServer 2158H V8 Server

xFusion FusionServer 2158H V8 Server

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

1

Configuration check

We verify CPU, memory, drives and cards against your order and the official spec.

2

BIOS & firmware

Firmware is updated and BIOS settings (boot order, virtualization, SR-IOV) are applied.

3

Stress test

CPU, memory and accelerators are exercised to confirm stability under load.

4

Storage & RAID

RAID arrays are built and every drive is confirmed healthy with no errors.

5

Test & record

The unit is tested, labels verified, and photographed for your records.

6

Export packing

Secure packaging protects the server during international air or sea freight.

Warranty you can rely on: every new xFusion 2158H V8 we supply is covered by a 3-year warranty, with responsive support and spare-parts availability.

Why xFusion

Proven at scale

xFusion servers are deployed across carrier, cloud and enterprise data centers.

Energy efficient

Dynamic energy management and high-efficiency Platinum/Titanium PSUs cut OPEX.

Open standards

PCIe 5.0, OCP 3.0 and Redfish make third-party integration straightforward.

Intelligent O&M

iBMC and optional FusionDirector enable remote, automated lifecycle management.

xFusion 2158H V8Typical 2U dual-socket

Maximum coresUp to 192 from one socketSplit across two CPUs
Memory12 × DDR5-6400More slots, two CPUs to fill
AcceleratorsUp to 4 dual-width GPUsSimilar, higher power draw
EconomicsOne CPU to license and serviceHigher software licensing cost
Honest note: the single-socket 2158H V8 often matches a dual-socket server while lowering your software licensing cost. If your workload needs two sockets, the established dual-socket xFusion 2288H V7 and the current-generation 1U 1288 V8 are our recommended alternatives. We will recommend the right platform rather than overselling any single one.
