How do I check compatibility for server parts?

Match by platform and part/FRU numbers, CPU socket, memory type (ECC RDIMM or LRDIMM), drive interface (SAS, SATA, NVMe), RAID or HBA support, NIC form factor (PCIe or OCP), and PSU wattage/connector.

Processors: Xeon or EPYC—what should I choose?

Intel Xeon offers broad software compatibility and strong per-core performance; AMD EPYC provides high core counts and memory bandwidth. Choose based on cores/threads, cache, TDP and socket/chipset support.

Storage drives: SAS vs SATA vs NVMe?

NVMe delivers maximum IOPS and low latency; SAS provides enterprise reliability and dual-path options; SATA offers cost-effective capacity. Verify bay size, caddy type and backplane interface.

Server memory: UDIMM vs RDIMM vs LRDIMM?

UDIMM (unbuffered, often ECC in servers) is common on entry or compact platforms but supports lower capacities; RDIMM (registered) is the standard choice for balanced capacity and stability; LRDIMM supports the highest capacities. Do not mix memory types in the same system. Match ECC requirement, speed (MT/s), ranks, voltage and per-CPU limits, and confirm that your platform supports UDIMM—many dual-socket servers require RDIMM or LRDIMM.

RAID controllers or HBAs—what’s right for me?

Select by interface (SAS/SATA/NVMe), required RAID levels (0/1/5/6/10/50/60), cache and battery-backed write-back for performance, and OS requirements—HBAs suit ZFS or software RAID.

Network cards: which NIC should I pick?

Choose the required speed (1/10/25/40GbE), copper or SFP+/SFP28, PCIe or OCP slot type, and driver support. Consider offload features for virtualisation and storage networks.

Power supplies: how do I size and select a PSU?

Use approved PSU models for your chassis, with suitable wattage and connector layout. Consider redundancy (1+1), future headroom for drives/GPUs and firmware compatibility.

Rail kits: will they fit my rack?

Confirm rack depth, hole type (square or round) and the exact rail kit model for your chassis generation. Some are tool-less; others require cage nuts.

Computational GPUs for servers—what should I know?

Verify PCIe lanes, PSU capacity and auxiliary power, cooling and airflow, plus chassis clearance. Choose VRAM size and ecosystem (CUDA/ROCm) to match the workload.

Warranty and returns—what do I get?

Most server parts include a 12-month warranty and a 30-day returns window. Coverage and any extended options are stated on each product page; all parts are tested and graded before dispatch.
