Server components and options encompass the field-replaceable and upgrade units that configure, expand, or sustain rackmount and tower servers: processors (single- and multi-socket CPUs from x86 and ARM architectures), memory modules (DDR4/DDR5 RDIMMs, LRDIMMs, and NVDIMMs), storage controllers and HBAs, NIC and SmartNIC adapters, GPU and accelerator cards, power supply units, cooling assemblies, riser cards, and chassis backplanes. Selecting correctly requires matching socket generation, TDP envelope, PCIe slot version and lane count, form factor (HHHL vs. FHFL), and vendor qualification lists—most OEMs publish approved component matrices that govern warranty support.

These parts serve data center operators expanding compute density for HPC or AI training workloads, IT teams upgrading existing server generations to defer full-platform replacement, and system integrators building custom configurations to specific memory-bandwidth or storage-throughput targets. Buyers should verify compatibility at both the platform and firmware levels before procurement, particularly for memory interleaving requirements and NIC offload feature dependencies.
