- Selection qualification
- CTO is a configuration base code, not a fixed installed BOM. Platform limits do not mean simultaneously installed CPU, RAM, drives or GPUs. Verify machine type, CPU count, memory, backplane, cooling and power. AI/HPC denotes an ordering scope, not included accelerators. Confirm local warranty and supply separately.
