WOLF-163S
Overview

System Switch + HPC in One 3U Slot
The VPX3U-BW5000E-SWITCH rugged 3U VPX module includes an NVIDIA RTX 5000 Blackwell embedded GPU, a PCIe Gen4 switch, and a 200 GbE network switch in a single slot-saving module. It can operate as both the system fabric switch and a high performance compute node, freeing chassis space for other payloads.
This slot-saving module merges three high performance elements; NVIDIA RTX 5000 Blackwell embedded GPU (10496 CUDA / 320 Tensor), Configurable PCIe Gen4 switch and a 200 GbE network switch (up to 8 × 25GbE + 1 × 1GbE) for flexible high-bandwidth Ethernet routing within the VPX chassis.
The NVIDIA Blackwell GPU architecture provides increased efficiency and 24GB of GDDR7 memory, delivering over 50% higher bandwidth compared to the previous generation.
WOLF's advanced cooling technology is designed to move heat efficiently from the hot devices to the wedgelocks, enabling sustained deterministic performance in harsh aerospace and defense environments.
Block Diagram
The block diagram illustrates the integrated NVIDIA RTX 5000 Blackwell GPU, PCIe Gen4 switch, and 200GbE Ethernet switch combined on one 3U VPX switch module. It highlights the PCIe fan-out paths that feed the GPU and uplink to the VPX backplane, alongside the high-bandwidth Ethernet fabric routes used to move sensor and mission data through the chassis.
Features
WOLF-163S is a rugged 3U VPX module designed for embedded AI and HPEC workloads. Powered by NVIDIA RTX 5000 Blackwell, it pairs high-throughput 200GbE and PCIe Gen4 connectivity with a SOSA/OpenVPX-aligned mechanical profile (SOSA Switch 14.4.15). The onboard 24 GB GDDR7 memory helps sustain bandwidth-intensive pipelines, while the integrated feature set supports deterministic performance across harsh -40°C to +85°C environments.

FAQ
Choose WOLF-163S when chassis slot budget is tight and you want to combine system fabric switching and GPU compute in a single 3U VPX slot.
This is most useful when:
- The chassis would otherwise need a dedicated Ethernet switch slot plus a separate GPU compute slot
- You want a compute node that can also serve as a fabric aggregation point for sensor/mission data
- You are building a modular VPX system where the switch role may need to scale with compute
If you have ample slots or want to physically separate switch and compute for fault containment or upgrade cadence, discrete modules can be the better program-level choice.
The integrated Ethernet switch is intended for high-bandwidth, flexible fabric routing within the VPX system.
Typical planning considerations:
- Port budgeting: common configurations support up to 8 ports at up to 25GbE plus a 1GbE management-style port (implementation/config dependent).
- Traffic separation: decide early how you will separate payload data, control/management, and any timing flows.
- Determinism features: TSN support can matter when your platform requires bounded latency or time-aware scheduling.
Net: treat WOLF-163S as both a compute resource and a fabric resource, and plan port allocation like you would for a standalone VPX switch module.
Confirm these items early to avoid backplane surprises:
- Switch slot profile alignment: SOSA-aligned 14.4.15 (this is a switch profile, not a payload compute profile).
- PCIe fabric expectations: an onboard PCIe Gen4 switch is present; confirm how you want PCIe fan-out to feed the GPU and other endpoints.
- Ethernet fabric mapping: confirm how 25GbE lanes map to backplane planes and whether your chassis wiring matches the intended topology.
- System management approach: plan for IPMI integration (monitoring, thresholds, inventory) like you would for a managed switch card.
This module is easiest to integrate when the chassis/backplane was already designed with a switch slot role in mind.
The key tradeoffs are usually about fabric behavior rather than raw GPU compute:
- Network configuration: determines port speed/port count presentation and how you partition traffic.
- PCIe switch configuration: affects how PCIe lanes are allocated between the GPU, uplinks, and peer endpoints.
- Power threshold (100W-180W envelope): must match chassis thermal headroom for sustained compute while switching at high throughput.
- Program control options: variant locking and conformal coatings can matter for deployed programs and configuration control.
