Sizing LLM Hardware for 50 Users
By Mamy Rakotomalala
A 50-person engineering team requires an optimized multi-GPU server to support concurrent inference without query latency spikes.
WHY IT MATTERS
Under-provisioning on-premise hardware leads to high queue delays, while over-provisioning wastes capital budget. Sizing hardware correctly ensures smooth concurrent performance at predictable costs.
GO DEEPER
- Concurrent usage estimate: Plan for 10 peak concurrent requests from a 50-person workforce.
- Target model selection: Deploy Llama 3.3 70B quantized to 4-bit precision.
- GPU memory requirement: Install 2x RTX 6000 Ada (96 GB total VRAM) for model weights and KV cache.
- Inference engine choice: Use vLLM with continuous batching to maximize memory throughput.
- Host system specs: Pair GPUs with 256 GB DDR5 RAM and a 32-core EPYC processor.
- Power and cooling overhead: Budget for a 1.5 kW server unit inside a rack enclosure.
THE BOTTOM LINE
Deploying a dual-workstation GPU server with vLLM comfortably supports 50 employees with low latency.
