DELL PowerEdge R640 1U rack server 2x Xeon Gold 6148 2.4GHz 20-core 256GB DDR4 2x 400GB SSD H730P

Dense 1U dual-socket compute

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 6148 processors running at 2.40 GHz with 20 cores each. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules. A PERC H730P RAID controller with 2 GB cache manages two 400 GB SATA SSDs. Redundant 750 W platinum power supplies, iDRAC9 Enterprise, quad-port networking and rails are included.

Virtualisation hosts needing maximum cores per U

This configuration suits dense virtualisation, container clusters or database nodes that benefit from 40 total cores and large memory capacity in a single rack unit. The eight 2.5-inch drive bays and dual 10 Gb SFP+ ports support high-throughput storage and network fabrics. Buyers who require more than two processor sockets, GPU acceleration or additional drive bays should evaluate alternative platforms.

PERC H730P RAID controller with 2 GB cache

The storage controller defines which RAID levels are available and whether a battery-backed cache protects in-flight writes. This unit provides RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Confirm that the supported SATA and SAS interface matches your drive selection before purchase.
