Server Parts for AI Infrastructure: GPU, NVMe, and High-Speed Networking
AI/ML infrastructure requires specialized server components — GPUs for compute, NVMe for data pipelines, and 100/200/400GbE for GPU-to-GPU communication. AI Server Stack Layer Component Recommendation Compute GPU NVIDIA H100/A100 (training), L40S (inference) Storage NVMe SSD High-endurance MU/WI for checkpointing Network InfiniBand/Ethernet ConnectX-7 (400GbE) or HDR InfiniBand Memory DDR5 Maximum capacity for data preprocessing GPU cross-reference […]
Server Firmware Update Best Practices: BIOS, BMC, RAID, NIC
Firmware updates fix bugs, improve performance, and patch security vulnerabilities. But a failed update can brick components. Follow these best practices. Update Order BMC first (iDRAC/iLO/XCC) — ensures management plane is stable BIOS/UEFI — after BMC is current RAID controller — may require reboot + rebuild NIC firmware — match driver version to firmware Drive […]
