About the ThinkSystem SR780a V3
The Lenovo ThinkSystem SR780a V3 is a 5U rack platform purpose-built for large-scale AI. At its core is an NVIDIA HGX 8-GPU baseboard — the same architecture used in hyperscale AI clusters — available with HGX B200 (180 GB HBM3e per GPU, up to 1.44 TB pooled), HGX H200 (141 GB) or HGX H100. All eight accelerators are linked by 8-way NVLink, so the complex behaves as a single, coherent training resource rather than eight separate cards.
Two 4th- or 5th-Gen Intel Xeon Platinum processors feed the GPUs, with up to 112 cores and 32 TruDDR5-5600 DIMM slots for as much as 4 TB of system memory — enough to keep data pipelines saturated during multi-node training. NVIDIA ConnectX-7 400G adapters and BlueField-3 DPUs provide the east-west fabric for scaling across a pod.
What sets the SR780a V3 apart is Lenovo Neptune direct-water cooling on both the GPU and CPU complex. Removing heat with liquid rather than air lets the eight 1000 W-class GPUs run at sustained clocks in dense racks, cutting fan power and data-centre cooling load. Servnet configures, supplies and supports the SR780a V3 across the UK — build yours to spec and request a competitive quote.
ThinkSystem SR780a V3 — FAQs
Which GPUs does the SR780a V3 use?
It ships with an NVIDIA HGX 8-GPU baseboard — either HGX B200 (180 GB HBM3e per GPU) or HGX H100 (80 GB), with 8-way NVLink. Both are factory liquid-cooled.
Is it air- or liquid-cooled?
The SR780a V3 uses Lenovo Neptune direct-water liquid cooling on the GPU and CPU complex, enabling sustained training throughput at high density.
Can I configure and price it?
Yes — build the SR780a V3 to your exact spec in our Lenovo configurator (processor, memory, HGX board, storage and support) and request a competitive UK quote.
