Dual-socket 1U rack server

The Dell PowerEdge R640 fits two Intel Xeon Silver 4116 processors in a single rack unit. Each CPU runs at 2.1 GHz with 12 cores and 3.0 GHz turbo. The system ships with 256 GB of DDR4 2400 MHz registered ECC memory across 24 slots. Two 800 GB SATA SSDs and a PERC H730P RAID controller provide storage. Quad-port networking adds two 1 GbE and two 10 Gb SFP+ links. iDRAC 9 Enterprise enables remote management. Redundant 750 W platinum power supplies and rails are included.

Upgrade from single-socket or older 2U units

This configuration replaces a single-processor server when workloads need 24 total cores and up to 3 TB of memory. The jump is worth it when virtualisation density, database throughput or container orchestration demand dual-socket performance in 1U of rack space. The H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache battery. The X520/I350 daughter card delivers 10 Gb SFP+ connectivity without extra adapters. iDRAC 9 Enterprise adds full lifecycle automation.

Verify rack depth, power

Confirm the cabinet accepts a 1U chassis with front-to-rear airflow and enough depth for the included rails. Ensure the PDU can supply two 750 W redundant feeds at the required voltage. The front panel holds eight 2.5-inch bays; only two are populated with 800 GB SATA SSDs so plan additional drives if capacity must grow. Memory uses DDR4 RDIMMs only — do not mix generations. Network uplinks require SFP+ transceivers and compatible switch ports for 10 Gb operation.

Vragen over dit artikel

What rack spacing and rail type are required to mount the 1U PowerEdge R640?

The server occupies 1U of rack height and ships with Ready Rails for tool-less mounting in standard 4-post racks.

How are the two Xeon Silver 4116 processors and the 256GB DDR4 memory installed, and what step is often missed?

Both CPUs are pre-installed in the two LGA 3647 sockets; the 256GB (8x 32GB) DDR4 2400MHz Registered ECC modules fill eight of the 24 slots — verify each DIMM clicks fully into its latch.

Which components in the R640 are hot-swappable and will need replacement over time?

The two 750W Platinum power supplies, the 2x 800GB SATA SSDs in the eight 2.5-inch bays, and the PERC H730P controller battery are all hot-swappable for later replacement.
