Computer Servers

Choose a tower for small offices or single-server needs with simple cooling and expansion; a rack server for data center environments where density, standardized mounting, and shared power/cooling matter; and blades when you need very high density and centralized management but have a compatible chassis and higher upfront infrastructure costs

Prioritize CPU cores and frequency for compute-heavy workloads, RAM capacity and ECC memory for virtualization and databases, and choose storage by workload: SSDs/NVMe for low-latency I/O, HDDs for large-capacity archiving, and consider RAID or software-defined storage for redundancy and performance

Look for onboard NIC speed (1GbE, 10GbE, or higher) and support for multiple ports if you need link aggregation or redundancy, consider built-in management interfaces (IPMI/iDRAC/iLO) for remote access, and check for optional fiber or SFP+ modules if your environment uses higher-speed or fiber networking

Check available CPU sockets, memory slots and maximum supported RAM, drive bays and interface types (SATA, SAS, NVMe), PCIe expansion slots for additional NICs or accelerators, and whether firmware and BIOS updates are readily available to support newer components

Plan for redundant power supplies and NICs, hot-swappable drive bays if uptime is critical, use RAID or distributed storage for data protection, implement monitoring and regular backups, and verify warranty and support options from the vendor

Evaluate server TDP and typical power draw under load to size power supplies and UPS capacity, consider energy-efficient processors and power supplies (80 PLUS ratings), and ensure rack airflow and data center cooling can handle the thermal output to avoid throttling and hardware failure

Compare warranty lengths, on-site vs. depot repair, availability of extended support and parts, firmware/software update policies, and the vendor's hardware lifecycle to ensure parts and security updates will be available for the expected service life
