Dual-socket 1U server for dense compute

The Dell PowerEdge R640 packs two Intel Xeon Platinum 8160 processors at 2.1 GHz with 24 cores each into a single rack unit. 128 GB of DDR4 2666 MHz registered ECC memory is installed across eight 16 GB modules. A PERC H730P controller with 2 GB cache manages storage, and dual 750 W platinum power supplies provide redundancy.

Suits virtualization and database clusters.

This configuration targets scale-out environments that need high core counts and fast networking in minimal space. The quad-port X520/I350 daughter card delivers two 1 GbE and two 10 Gb SFP+ links, while iDRAC 9 Enterprise handles remote management. Buyers who need GPU acceleration or more than eight 2.5-inch drive bays should look at other platforms.

400 GB boot tier with room for six more drives

Two 400 GB SATA SSDs give a fast mirrored volume for the hypervisor or operating system. The eight-bay chassis leaves six slots open for additional SAS or SATA drives, letting you expand capacity or add a separate data array. Memory scales to 3 TB across 24 slots when workloads grow beyond the current 128 GB.
