DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6142 2.6GHz 16-Core 256GB DDR4 2x 400GB SSD

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 6142 processors, each running at 2.6 GHz with 16 cores. The system includes 256 GB of DDR4 registered ECC memory across 24 slots. Redundant 750 W platinum power supplies and a front bezel with rails are included.

Suits virtualisation hosts needing maximum core

This configuration suits virtualisation hosts and compute clusters that need 32 total cores and 256 GB of DDR4 memory in a single rack unit. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache. Buyers who need more than two processors or require 3.5-inch drive bays should look elsewhere.

256 GB DDR4 registered ECC memory across 24 DIMM

The installed 256 GB of DDR4 2666 MHz registered ECC memory occupies eight of the 24 available slots. This leaves 16 slots free for expansion up to the 3 TB maximum capacity. The memory type and slot count are the decisive factors when planning future upgrades or validating compatibility with existing modules.
