Supermicro vs HPE for NVIDIA AI servers.
Side by side from our vendor index: what each firm actually designs, which NVIDIA platforms it ships, and the identity facts that shape a procurement decision. Sources and full detail live on each profile.
Supermicro
The reference pure-play. Supermicro designs boards, chassis, power and liquid cooling in-house and is routinely first to ship each NVIDIA generation, from HGX nodes to full GB300 NVL72 racks. For time-to-GPU it is usually the benchmark the rest of the market is measured against.
- DLC-2: second-generation in-house direct liquid cooling with own in-rack CDU (250kW) and in-row CDU (1.8MW); cold plates on CPU, GPU, memory, PCIe switches and VRMs, up to 98% heat capture, 45C inlet liquid
- Own server motherboard design lineage since 1995; current X14 (Intel) and H14 (AMD) platform families
- In-house BMC firmware stack and management tooling with Root-of-Trust on ASPEED silicon
- Data Center Building Block Solutions: end-to-end rack-scale integration including power shelves, coolant manifolds, networking and management software
HPE
HPE brings the Cray lineage to enterprise AI: genuine in-house direct-liquid-cooling engineering proven on exascale systems, applied to ProLiant and Cray XD NVIDIA platforms up to GB300 NVL72 scale. Strong where the buyer wants supercomputing discipline with OEM support.
- Cray supercomputing heritage (acquired 2019): the source of HPE's HPC and DLC engineering stack
- Industry's first 100% fanless direct liquid cooling architecture (Oct 2024): 8-element design covering GPU, CPU, blade, storage, fabric, rack, pod and CDU; claims 90% cooling-power reduction vs air
- Slingshot: proprietary Cray-developed interconnect used in DOE exascale systems
- iLO BMC: HPE designs its own iLO ASIC with silicon root of trust
