DELL PowerEdge R640 1U rack server 2× Xeon Gold 5118 2.3 GHz 12-core 512 GB DDR4 2× 800 GB SSD H730P

Dense 1U dual-socket server

The Dell PowerEdge R640 fits two Xeon Gold 5118 processors and 512 GB of DDR4 memory into a single rack unit. A PERC H730P controller manages two 800 GB SATA SSDs with RAID levels up to 60. Quad-port networking adds two 1 GbE and two 10 Gb SFP+ links, while iDRAC9 Enterprise provides full remote management. Redundant 750 W platinum supplies and rails complete the package.

Suits scale-out compute.

This configuration targets virtualization, cloud and HPC clusters that need maximum CPU cores per rack slot. The 1U chassis leaves no room for full-length GPU cards or more than eight 2.5-inch drives. Buyers who need hardware acceleration or dozens of terabytes in one box should look at larger form factors.

512 GB DDR4 registered ECC across 24 slots

Memory is the spec that decides fit: sixteen 32 GB modules fill 16 of 24 DIMM sockets at 2400 MHz, leaving eight slots open for expansion to the 3 TB platform maximum. Any workload that exceeds the installed capacity or requires a different memory generation will need a different configuration.
