DELL PowerEdge R640 1U 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 running at 2.6 GHz with 16 cores each. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. Eight 800 GB SATA SSDs and a PERC H730P 2 GB storage controller provide the primary storage subsystem.

Virtualisation hosts and database clusters needing

This configuration suits virtualisation hosts and database clusters that benefit from 32 total cores and large memory capacity. The quad-port network daughter card with two 1 GbE and two 10 Gb SFP+ ports supports demanding east-west traffic. Buyers who need more than two processors or require GPU acceleration cannot expand beyond the 1U form factor.

512 GB DDR4 registered ECC memory installed

The server arrives with 512 GB of DDR4 registered ECC memory installed in 16 of 24 available slots. The maximum supported capacity is 3 TB when all slots are populated. This specification determines whether the system meets immediate workload requirements or requires additional memory procurement before deployment.

Questions about this item

How does the dual 16-core 2.6 GHz Xeon Gold 6142 configuration perform in a live 1U rack server?

Two Xeon Gold 6142 processors deliver 32 total cores at 2.6 GHz with 3.7 GHz turbo, giving high thread density for virtualization and database workloads inside a 1U chassis.

What does the PERC H730P 12 Gb/s SAS/SATA controller cap in real RAID arrays?

The H730P supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through at 12 Gb/s SAS and 6 Gb/s SATA, limited by the eight 2.5-inch drive bays.

What rails and clearance does the 1U R640 need to mount in a standard rack?

The server includes Dell Ready Rails for tool-less mounting in a 1U space and requires a four-post rack with standard square-hole spacing.
