Server Hardware Explained: CPU, RAM, RAID and More for UAE Buyers

Understanding What Goes Into a Server

Servers look like beefy PCs, but the components are engineered for 24/7 reliability. Here's what each part does and why it matters when buying in the UAE.

Processors (CPU)

Servers use enterprise CPUs — Intel Xeon Scalable or AMD EPYC. Key considerations:

• Core count — more cores for virtualisation and parallel workloads
• Clock speed — higher for latency-sensitive apps
• Sockets — single for smaller loads, dual to double capacity

Memory (RAM)

Servers use ECC (Error-Correcting Code) memory that detects and fixes bit errors — essential for stability. Registered (RDIMM) memory allows very large capacities. Entry servers start around 32–64GB; virtualisation hosts run 256GB and beyond.

Storage and RAID

RAID combines drives for performance and redundancy:

• RAID 1 — mirroring, simple redundancy
• RAID 5/6 — striping with parity, good capacity + resilience
• RAID 10 — striping + mirroring, best performance with redundancy

Drive types:

• NVMe SSD — fastest, for databases
• SATA/SAS SSD — balanced
• SAS/SATA HDD — high capacity, lower cost

Redundant Power Supplies

Enterprise servers ship with dual hot-swap PSUs so one can fail (or one power feed can drop) without downtime — critical in any UAE data centre.

Out-of-Band Management

• Lenovo XClarity Controller (XCC)
• Dell iDRAC
• HPE iLO

These let admins manage the server remotely — power cycle, mount media, monitor health — even if the OS is down.

Hot-Swap Everything

Drives, PSUs and fans that swap without shutting down keep uptime high.
