WOLF-167S
Overview
System Switch + HPC in One 3U Slot
The VPX3U-BW2000E-SWITCH rugged 3U VPX module integrates three high-performance elements in a single, slot-saving SOSA-aligned switch card; NVIDIA RTX™ 2000 Blackwell embedded GPU (GB206), Configurable PCIe Gen4 switch, and a Configurable 200 GbE network switch.
The Blackwell GPU delivers parallel compute for embedded HPC/AI workloads and includes 8 GB of GDDR7 memory with ECC support. The module can operate as both the system fabric switch and an HPC node, allowing the PCIe and Ethernet fabrics to be routed while still provisioning a dedicated PCIe path to feed the GPU.
Module power is configurable from 75W to 140W, enabling the designer to tune power/thermals to chassis cooling capability and mission profiles.

FAQ
WOLF-167S combines three functions in one 3U VPX slot: an embedded GPU compute node, a PCIe Gen4 switch, and a high-bandwidth Ethernet switch fabric.
It is typically used when:
- You want a slot-saving system switch that can also run GPU workloads
- You need to route PCIe and Ethernet fabrics while still provisioning a dedicated GPU data path
- You want to reduce the number of separate switch and compute cards in the chassis
Choose WOLF-167S when slot count, weight, and fabric simplicity matter and you can accept a combined-function card.
It is most compelling when:
- You are tight on 3U slots and need both switching and compute
- You want shorter integration cycles with fewer inter-card dependencies
- Your platform can accommodate the combined power and thermal load in one slot
If you need independent scaling of switch capacity and GPU capacity, separate cards can be cleaner.
Prioritize:
- PCIe Gen4 fabric stability and correct routing for the intended uplinks and endpoints
- Ethernet switch behavior under load (port mapping, throughput, latency, TSN behavior if used)
- GPU data path validation (sustained transfers and workload stability)
- Power/thermal margin at your chosen power threshold and chassis cooling capability
Contact Sales for ordering numbers and switch configuration options.
The key ordering-time choices are primarily about fabric behavior and integration fit:
- Network switch configuration: determines port speed/port count presentation and how you partition traffic across the chassis
- PCIe Gen4 switch configuration: determines lane allocation between uplinks, GPU feed, and any downstream endpoints
- Slot profile alignment: the module aligns to a switch-slot profile (14.4.15), which drives backplane compatibility and role in the chassis
- Power threshold selection: must match chassis thermal headroom while switching at high throughput and running GPU workloads
