Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. The system includes 128 GB of DDR4 2400 MHz registered ECC memory across eight 16 GB modules.

Virtualisation hosts and database nodes

This configuration suits organisations running virtualised workloads, database clusters or high-performance computing tasks that benefit from 24 total cores and large memory capacity. The eight 2.5-inch drive bays with a PERC H730P controller support SAS and SATA drives in multiple RAID levels. Buyers needing more than eight internal drives or a different processor generation should evaluate alternative platforms.

PERC H730P 2 GB storage controller

The Dell PERC H730P 2 GB 12 Gb/s SAS/SATA controller with battery-backed cache enables RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. It manages the two installed 300 GB 10K SAS drives and any additional drives added to the eight-bay chassis. This controller choice determines the RAID capabilities and drive compatibility for the deployment.

Questions about this item

How do I install the server in a rack, and which step is commonly missed?

Mount the included Ready Rails into a standard 1U rack space, slide the chassis in, and secure the front bezel — many forget to latch the bezel, which blocks airflow.

What maintenance will the storage controller battery need later?

The PERC H730P 2GB controller uses a backup battery that typically requires replacement every 3 to 5 years to preserve write-cache protection during power loss.

What limit appears first when both CPUs run sustained workloads?

The 750 watt redundant power supplies set the thermal and electrical ceiling; sustained dual-CPU loads can reach the supply rating before CPU turbo limits engage.
