Additional InformationTwo 9.5mm E1.S Gen4 NVMe hot-swap bays handle primary storage along with one internal M.2 slot supporting 2242/2260/2280/22110 cards with a SATA interface. Built around a single 5th or 4th Generation Intel Xeon Scalable processor, the TO25-S12 Compute Node provides up to 64 cores and a maximum TDP of 250W. The platform includes 8x DDR5 RDIMM slots configured across 8x channels for up to 2TB of memory capacity. 5th Gen Intel Xeon processors support up to 5600 MT/s while 4th Gen Intel Xeon processors support up to 4800 MT/s. GPU and expansion capabilities include support for 1x dual-slot PCIe Gen5 GPU along with additional PCIe Gen5 slots.
Expansion Slots:
1 x FHFL PCIe Gen5 x16 slot for GPUs
1 x FHFL PCIe Gen5 x16 slot
2 x FHHL PCIe Gen5 x16 slots
1 x LP PCIe Gen5 x8 slot
With one 1 Gb/s management LAN for networking, the TO25-S12 Node supports a 48V DC bus bar power solution and ASPEED AST2600 BMC for remote management. Offering balanced power consumption to rack density the TO25-S12 is based on the Open Compute Project (OCP) specifications and is designed for a 21” OCP rack. Built for single-phase immersion cooling environments, this system delivers complete support for the NVIDIA AI software stack.
